    Lexus Announces IS With 2.0L Turbo Four... For Europe


    • The IS Gets A New Base Engine... For Europe


    The Lexus IS is quite good vehicle - aside from the looks - but it has one big problem. The base 2.5L V6 is a bit of a dog. There isn't enough power to move the IS around. Luckily, Lexus has a solution for this problem in Europe for the time being.

     

    Meet the Lexus IS 200t which has the same turbocharged 2.0L four found in the NX crossover. This produces 245 horsepower and 258 pound-feet of torque. The engine will come paired with an eight-speed automatic. Lexus claims an 7 second run to 60 MPH and combined fuel economy of 33 MPG on the European cycle.

     

    The IS 200t will go on sale in September in Europe. The U.S. will be getting the IS 200t, but no date as to when we'll see it.

    LEXUS TO LAUNCH IS 200t WITH INNOVATIVE 2.0l TURBO PETROL ENGINE

    • New turbo engine offers superior smoothness and responsiveness, with no turbo-lag and high fuel efficiency
    • Engine mated to 8-speed Sport Direct Shift transmission
    • IS 200t on sale in Europe as from September 2015


    Brussels, Belgium - Lexus is expanding the range of vehicle equipped with its new 2.0-litre turbo engine. Following the launch of NX 200t in early 2015 and the announced arrival of RX 200t by the end of the year, IS is the third Lexus model to be fitted with this new engine.

     


    Powered by a new 2.0-litre petrol turbo engine – with innovative D-4ST fuel injection technology for both fuel economy and instantaneous torque – the Lexus IS 200t sports sedan delivers 245 DIN hp (180kW) with a maximum torque of 350 Nm. Capable of rapid acceleration up to a top speed of 230 km/h, its 8-speed Sport Direct Shift transmission was developed for the high-performance RC F.

     

    Featuring a breakthrough combination of water-cooled cylinder head, integrated exhaust manifold and twin scroll turbocharger, this all-new Lexus 2.0-litre turbo engine delivers fast throttle response, performance and high torque at low engine revs. For enhanced fuel economy, innovative valve timing (VVT-iW: Variable Valve Timing intelligent - Wide) allows the engine to switch between the Otto and Atkinson cycles.

     

    The IS 200t returns a 0-100 km/h acceleration time of 7.0 seconds and an average fuel consumption of 7.0l/100 km.

     

    Cylinder Head with Integral 4-into-2 Exhaust Manifold and Twin-Scroll TurboThis innovative, combination of engine technologies has been designed to provide a high level of responsiveness with minimal turbo lag and enhanced low speed torque, and yet return an improved fuel economy.
    The four-into-two exhaust manifold system pairs cylinders according to their expansion or compression stroke. Acting in conjunction with the highly-efficient, twin-scroll turbocharger, this innovative manifold structure prevents interference between the exhaust gasses from each cylinder, generating high torque across the widest possible rev range.

     

    The engine further employs an air to liquid intercooler mounted directly to the engine to significantly reduce the intake volume downstream of the turbocharger, minimising turbo lag for a highly responsive performance.

     

    The twin-scroll turbocharger itself features variable waste gate valve control. This minimises pumping losses by reducing back pressure during low engine loads when the turbo is not required realising good fuel economy.
    In addition, the integration of the exhaust manifold within the cylinder head enhances exhaust gas cooling without sacrificing catalyst warm-up performance. This not only helps to suppress catalyst deterioration, but also expands driving range at the optimum, stoichiometric air-fuel ratio.
    D-4ST Fuel Injection System
    D-4ST (Direct injection 4 stroke gasoline engine Superior version with Turbo) combines a high pressure fuel system for injection directly into the cylinders with a low pressure system for injection into the ports. Injection is split between the direct and port injectors according to the engine load, optimising fuel combustion in all driving situations to enhance both low speed torque and fuel economy.

     

    This advanced fuel injection system works in combination with turbocharging technology to create a high level of compatibility between the 'high tumble ratio' achieved by optimising the shape of the cylinder head intake ports and the piston tops, and turbo 'boost control'.

     

    Innovative Dual VVT-iW TechnologyOptimising torque throughout the engine rev range and allowing the engine to start in the Otto cycle and yet run in the more fuel efficient Atkinson cycle, the new Lexus turbo features innovative dual variable valve timing technology which adopts VVT-i to the exhaust valves and VVT-iW to the intake valves, but also delivers wide open throttle performance.
    The late intake valve closing of the Atkinson cycle reduces pumping losses and boosts fuel economy. VVT-iW incorporates a mid-position lock which not only enables the Atkinson cycle to be maintained without sacrificing starting performance in cold weather.
    Further Advanced Features
    The new 2.0 litre turbo engine is remarkably light and compact. Cast with low nickel content heat resistant steel, and featuring a resin cylinder head cover, intake manifold and intake pipes, it weighs just 160 kg. The unit was bench-tested for more than 10,000 hours before extensive on-road testing began, during which it then covering more than one million kilometres.

     

    Several measures have been adopted to reduce friction losses within various parts of the engine, enhancing fuel economy. The adoption of an offset crankshaft lowers the piston thrust load to reduce friction losses. Cylinder bore machining has been improved and a piston surface treatment applied to the piston skirts, reducing sliding resistance. Low tension piston rings have been used, and the weight of reciprocating parts reduced.

     

    A lightweight roller rocker valve train and a low friction timing chain have been adopted, and the sliding parts of the chain fabricated in a low friction material. Low friction materials have also been used for the crankshaft oil seals, and the flow of lubricating oil optimised, with oil pump flow reduced through the adoption of a variable discharge mechanism.

     

    Careful heat management within the engine further improves fuel efficiency. To that end, a cylinder block rapid warm-up system suppresses the flow of coolant into the block when the engine is cold, and a piston cooling oil jet control system cuts the supply of oil to the pistons to improve warm-up speeds.

     

    Smoothness, Quietness and a Better Turbo SoundWith the rigidity of the main structural components already optimised to suppress vibration, the new engine is further equipped with a balance shaft featuring resin gears for even greater smoothness.
    Newly developed lubricating calcium free oil removes the chance of engine knock at low engine revolutions, and the piston cooling oil jet system further improves anti-knock performance.
    The water-cooled intercooler provides strong advantages in starting off acceleration and a 0.3-second reduction in 0–100km/h acceleration time over an air-to-air type alternative. The acceleration curve prioritises torque delivery at low speeds.

     

    Turbo engines tend to be noisy when the throttle is closed (referred to as the ‘turbo sigh’). An electric air bypass valve and resonator have been adopted to greatly reduce characteristic turbocharger noise. As a turbocharged engine requires smooth intake flow for performance, Lexus engineers focused on creating special duct shapes which deliver power without noise.

     

    Eight-speed transmission with paddle shiftsThe IS 200t also received the 8-Speed Sport Direct Shift transmission with paddle shifts, originally developed for the RC F high-performance coupe. The rear wheel drive IS 200t is the first Lexus sedan to vary gear shifting in accordance to G-forces.
    The transmission automatically downshifts during hard braking before a corner then holds a lower gear through the corner for best control and then selects the most suitable gear on corner exit to give the driver greater throttle response.
    The IS 200t will be available as from September 2015.

    They should put the turbo 4 in the IS.  That 2.5 V6 is hopelessly underpowered.  205 hp from a V6?  What is it, a 1997 Lesabre?

    I'd be more interested in seeing a hybrid IS, but Toyota has said they will not do one in the U.S.  The IS has had essentially the same engines since model year 2006.  Your would think they would have had updates by now.

    Well hopefully those extra horses will give it adequate power but I doubt it's going to give it much of a kick.

     

    "0-60 in 8 seconds"

     

    I'm very skeptical.

    Lexus claims an 8 second 0-60? They must have let Hyundai tune it.

     

    Well hopefully those extra horses will give it adequate power but I doubt it's going to give it much of a kick.

     

    "0-60 in 8 seconds"

     

    I'm very skeptical.

     

    Whoops.. I made a slight error.

     

    0-60 in 7 seconds it should say.

    7 sec is a bit more reasonable. Hopefully they're sandbagging because the turbo-4 ATS and 3 series crush that. Even the refreshed ILX can crack the high 6's with 202 horsepower.

      Lexus executives admit there are some holes in their lineup such as not having a subcompact or three-row crossover. Speaking with Automotive News, Lexus General Manager Jeff Bracken said the brand is losing as many as 70,000 potential vehicle sales by not competing in certain segments. 
      "We do think there's room to fill some gaps that still exist for Lexus," said Bracken.
      One possibility is introducing a subcompact crossover possibly with a production version of the UX concept.
      "That's a gap we are watching very closely. We're very fixated on trying to move that conversation forward with our parent corporation." 
      Also up for consideration is a three-row crossover and expanding the F-series performance family - might include an LC-F.
      One surprise to come out is Lexus doing an electric vehicle. According to Bracken, the brand started investigating possibilities after the Paris Motor Show where many European luxury automakers pushed this idea.
      "It was amazingly focused. Subsequent to that show, from my standpoint, we began conversations with our product planners," said Bracken.

      Almost three decades ago at the Detroit Auto Show, Toyota shocked the establishment with the introduction of Lexus and LS 400 flagship. Lexus hopes with the 2018 LS introduced this morning in Detroit is able to recapture some of that shock.
      The look of the 2018 LS is familiar and somehow different. The profile is the similar to the current LS, but Lexus made a number of changes to make it stand out. There is a more aggressive take on the spindle grille, a crease running along the doors, lower ride height, and larger wheels. The new GA-L platform that made it's debut last year on the LC coupe underpins the LS. It has been stretched and widened to provide measurements of 206.1-inches long 74.8-inches wide, and 57.1-inches tall. This makes it about the same size as a BMW 7-Series long-wheelbase.
      Power comes from an all-new 3.5L twin-turbo V6 engine with 415 horsepower and 442 pound-feet of torque. This comes paired with a new ten-speed automatic. Lexus says the LS with this engine will hit 60 mph in 4.5 seconds. It is unknown whether or not a V8 or hybrid option will be introduced down the road. The front and rear multilink suspension setup from the LC is employed on the LS. An air suspension system is optional.
      The interior takes some ideas from the LC with a similar instrument cluster with traction control and drive mode selectors sitting on either side. The seats have been redesigned and now feature 28-way power adjustments for those sitting up front. Rear seat passengers can get reclining seats, an ottoman, and Shiatsu massage functionality. Tech-wise, there is a new version of Lexus' remote touch system with a 12.3-inch infotainment system and optional 24" color heads-up display which the automaker claims is the largest in the world.

      With the All-New 2018 LS, Lexus Reimagines Global Flagship Sedan
      Radical new design with coupe-like silhouette, yet spaciousness of prestige sedan New platform for greatest-ever LS agility and comfort All-new twin-turbo V6 with 415 horsepower 10-speed automatic transmission All-new available Lexus Advanced Safety Package New level of flagship luxury in every aspect Interior inspired by traditional Japanese aesthetics On sale in U.S. near the end of 2017 DETROIT, January 9, 2017 — It is possible that no single automobile has, upon introduction, upended its category as decisively as the first Lexus LS did when it launched the luxury brand 28 years ago. The 1990 LS 400 was the original luxury disruptor, winning critical acclaim and astonishing customers by setting new benchmarks for comfort, powertrain performance and smoothness, quietness, build quality, attention to detail, and dependability. The brand supported that groundbreaking vehicle by setting and maintaining new standards for customer service and satisfaction.
       
      Now, Lexus is about to repeat history with the introduction of the all-new, fifth-generation LS flagship sedan for 2018, unveiled at the 2017 North American International Auto Show. Inside and out, the new LS reflects a strong, uniquely Japanese identity and approach to luxury. Yet, the LS was designed to be the brand’s latest global citizen, available in about 90 countries.
       
      “Not only will the LS symbolize the Lexus brand, it will become the definitive new-generation luxury car embodying Japanese tradition and culture,” said Toshio Asahi, chief engineer for the new LS. “As such, this global pinnacle must go far beyond what the world expects from a luxury car.”
       
      Longer, Lower, Wider – and More Exciting
       
      Longer and lower than the sedan it replaces, the all-new LS debuts a strikingly bold design with a coupe-like silhouette punctuated by the Lexus design language. A new driver-centric performance feel comes from building the LS on the company’s all-new global architecture for luxury vehicles (GA–L). This premium rear-wheel drive platform, an extended version of the one used for the stunning new Lexus LC 500 coupe, will offer a more dynamic experience on the road while further elevating renowned Lexus comfort. 
       
      The original Lexus LS won acclaim by anticipating what luxury customers would want, rather than simply amplifying what established luxury automobile brands offered at the time. In that spirit, the 2018 LS sedan’s spacious cabin, unique appointments and visionary technology will once again surprise customers by resetting expectations for a global flagship sedan.
       
      “We set previously unheard of targets and resolutely pushed ahead towards these ambitious goals,” said LS chief engineer, Asahi. “The customers who are going to want to own a Lexus flagship are already surrounded by luxury on a daily basis, people who have a sharp eye for authenticity to begin with. We wouldn’t turn their heads with a conventional premium product.”
       
      A Flagship Reborn
       
      Just as the original LS launched the Lexus brand, the all-new 2018 LS continues the brand’s more dynamic direction. Each generation of LS sedans leading up to this iteration advanced luxury, craftsmanship, performance and safety in their own way, with the most recent also introducing a far more emotional design and engaging on-road performance.
       
      To create the all-new LS, Lexus took the approach of starting from new, reimagining what a flagship sedan should be, as if launching the brand all over again. The goal was not to improve on what Lexus has done, but to exceed expectations of global luxury customers.
       
      A common thread going through all LS models remains: Omotenashi, the concept of Japanese hospitality. Applied to a luxury automobile, it means taking care of the driver and passengers, anticipating their needs, attending to their comfort and helping to protect them from hazards.
       
      Vehicle Dynamics
       
      More than ever before, luxury sedan drivers demand greater handling agility and performance feel without sacrificing comfort. It’s one of the most difficult balances to achieve in a vehicle, yet the new Lexus global architecture for luxury vehicles (GA–L) meets the challenge. The new platform debuted in the LC 500 coupe and now, with a longer wheelbase, underpins the new LS. To enhance center of gravity height and weight distribution, the new LS has a wide and low design.
       
      The GA-L platform is the stiffest in Lexus history, setting the stage for enhanced handling, ride smoothness and cabin quietness. The 123-inch wheelbase is 1.3-inch longer than the current LS long-wheelbase model.
       
      Helping to provide the uncanny ride and handling balance in the new LS is the latest generation of a chassis control technology known as Vehicle Dynamics Integrated Management (VDIM). This system implements cooperative control of all vehicle subsystems – braking, steering, powertrain, and suspension – to control basic longitudinal, lateral and vertical motion as well as yaw, roll and pitch. Optimal control of these motions helps to enable exceptional ride comfort, enhanced traction and safety and handling agility. Handling can be further enhanced by active stabilizer bars and the Lexus Dynamic Handling (LDH) System with independent front and rear steering. VDIM is capable of aiding stability when the car is traversing split-friction surfaces, such as dry pavement and ice.
       
      In creating the new LS, engineers used lightweight materials including ultra-high tensile steel sheet and aluminum to carve over 200 pounds from the current LS platform and body. These savings, along with the implementation of the new V6 engine and enhanced body rigidity, allow for a more dynamic driving experience. 
       
      Critical to its driving performance, the new platform lowers the car’s center of gravity by placing most of the mass, including the engine and the occupants, in a position more centralized and lower in the chassis. Special braces in the engine compartment, stiff aluminum front and rear suspension towers, and other features help bolster the strength of key chassis structures.
       
      The LS has a history of outstanding suspension compliance, yet Lexus saw opportunity for new gains in this realm as well. For example, the multilink suspension employs double ball joints on the upper and lower control arms to help allow for control of the smallest movements from the driver inputs and road conditions. Beyond sharing workload, a dual ball joint arrangement helps optimize suspension geometry to increase wheel control and yield more precise steering response with better initial effort. To reduce unsprung weight and therefore aid agility and comfort, aluminum is used extensively in the suspension.
       
      LS Performance and Smoothness Redefined: Twin-Turbo V6 and 10-Speed Transmission
       
      For both high power and excellent fuel efficiency, Lexus designed an all-new 3.5-liter V6 engine specifically for the new LS with all-new twin turbos developed through the company’s F1 technology. This new engine in the LS is indicative of the more dynamic approach being taken by Lexus, offering V8-level power without sacrificing fuel economy—all while minimizing noise and vibration. The new LS engine offers the output one would expect in a flagship sedan: 415 horsepower and 442 lb-ft of torque, sizeable gains over the current LS model’s V8. The long stroke and optimized stroke-to-bore ratio contribute to high-speed combustion and the efficiency of the twin turbos, which assist the LS with a projected 0-60 time of 4.5 seconds (RWD).     
       
      Perhaps more critical is how Lexus tuned the engine and transmission to deliver instant acceleration and a constant buildup of torque toward the engine’s redline.
       
      A ladder frame structure in the cylinder block, redesigned engine mounts, electric wastegates and numerous other features help ensure the remarkable powertrain smoothness, a Lexus hallmark. The driver will be able to tailor powertrain response and feel by choosing from Normal to Sport to Sport+ modes, and just enough of the exhaust note can be heard to enhance the sporty feel.
       
      The first-ever 10-speed automatic transmission for a premium passenger car, having already debuted in the Lexus LC 500, is also used in the new LS flagship sedan. It is a torque-converter automatic, yet with shift times that rival those of dual-clutch transmissions. The wide bandwidth afforded by ten closely spaced ratios is ideal for all forms of driving, helping to provide an optimal gear for all conditions.
       
      Shifting via paddles is available, yet many will prefer the advanced electronic control system, which anticipates the driver’s input. The system chooses the ideal ratio by monitoring the acceleration, braking and lateral-g forces.
       
      For starting acceleration, the close ratios of the low gears and the shortened shift time enable a rhythmical and exhilarating acceleration feel. The high torque of the twin-turbo engine matches ideally with the higher gear ratios for effortless, serene highway cruising, yet very quick downshifts yield direct acceleration with no lag in G response.
       
      Torque converter lock-up activates in all ranges except when starting off to provide a direct feel, while also supporting fuel efficiency.
       
      Crafting a Unique Identity
       
      “The LS is the flagship of the Lexus brand,” said chief designer, Koichi Suga. “More than any other model, it embodies the history and image of Lexus and serves as a symbol for everything the brand stands for.”
       
      Following the “Yet” philosophy that has been passed on since the first-generation LS, Lexus created a design offering the room and comfort of a prestige “three-box” sedan, yet with the stylish silhouette of a four-door coupe that holds stronger appeal for younger luxury customers.
       
      Lexus designers took full advantage of the new platform, with its lower profile and length on par with that of a prestige long-wheelbase sedan, to give the new LS a stretched, ground-hugging appearance. Compared to the current LS, the new model is about .6 inches lower, while the hood and trunk are approximately 1.2 inches and 1.6 inches lower, respectively. The new LS is the first Lexus sedan with a six- side window design. Also a first for a Lexus sedan, the flush-surface windows smoothly integrate with the side pillar.
       
      To preserve headroom with the lower profile, the new LS features an outer slide-type moonroof. The unique rendition of the spindle grille mesh, with a texture that seemingly changes in different light, is the result of both intense CAD development and hand-adjusting thousands of individual surfaces.
       
      The LS debuts five wheel designs, including two new 19- and three 20-inch wheel designs. The 20-inch premium wheels employ a brilliant appearance created using an electroplating technique known as sputtering. All but one of the wheel designs feature a hollow rim structure that helps reduce the resonance sound generated by the tires.
       
      Progressive Comfort with Traditional Inspiration
       
      Creating a new standard of flagship luxury is not simply a matter of adding more features. Inspired by the omotenashi principle, Lexus sought to instill the new LS cabin with luxury that welcomes and envelops the occupants while treating the driver like a partner.
       
      “I suggest that you simply open the door and experience that immediate, intuitive sense that you’re looking at an interior that is unlike any luxury car before,” said chief designer Suga.
       
      New seating designs, including available 28-way power front seats that feature heating, cooling and massage, exemplify this approach. The organically shaped dash design clusters information displays at uniform height to support the “seat-in-control” layout that emphasizes the driver’s ability to operate all systems without the need to change posture.
       
      While making the new LS even more of a driver’s car, Lexus also lavished attention to the rear seat, developing a design that creates seamless, enveloping continuity between the trim and seatbacks for passenger egress.
       
      Options for heating, cooling and massage make the rear seat a welcoming environment. The available power front and rear seat with Shiatsu massage and a raised ottoman, part of a wider rear seat luxury package, offers the most legroom of any previous-generation LS. In addition, the seat behind the front passenger in this optional package can be reclined up to 48 degrees, and can be raised up to 24 degrees to help assist the rear-seat passenger in exiting the vehicle.
       
      Because the new LS is lower than previous versions, Lexus, for the first time, equipped the available air suspension with an access function. Activated by unlocking the car with the smart key, access mode automatically raises the vehicle and opens the seat bolsters to welcome drivers behind the wheel.
       
      The Intersection of Tradition and Technology
       
      Lighting and attention to detail express a unique aesthetic in the LS. A new approach to creating trim elements again turned to Japanese culture, combining traditional Japanese aesthetic with advanced manufacturing techniques. This is reflected in signature touches, such as beautiful interior ambient lighting inspired by Japanese lanterns and armrests that appear to float next to the door panel.
       
      Inspired by Shimamoku wood patterns, the new forms that combine the artistic combination of natural woodwork and application of Japan’s sophisticated sliced wood and laser cutting manufacturing technologies can be seen in the new LS. New patterns include Art Wood Organic, Art Wood Herringbone, and Gray Sapele Wood with Aluminum. Compared to the straight-grain Shimamoku pattern, the new LS cross-grain is a larger pattern featuring bolder contrasts between light and dark, giving the wood a more vibrant appearance.
       
      The Sounds of Near Silence – or Great Music
       
      Lexus tuned the LS exhaust to convey a more authoritative tone, yet also designed the cabin to ensure utterly quiet cruising. New sound suppression methods further hush the environment compared to previous LS models. Active Noise Control quiets the cabin even more by detecting the sound of the engine coming into the vehicle and cancelling certain frequencies using antiphase sound from the audio speakers.
       
      The serenity of the LS cabin provides an ideal stage for the standard premium audio system or the audiophile-worthy available 3D surround Mark Levinson audio package with in-ceiling array speakers. The package features a more inviting graphic user interface. Its next-generation remote touch is designed to mimic smartphone operation, also supporting handwritten input. In addition to its 12.3-inch wide navigation display, the LS can incorporate an optional 24-inch color heads-up display (HUD)—the largest in the world—that projects a variety of information onto the driver’s forward view.
       
      Advanced Safety Features and Driver Support
       
      Structurally, the all-new Lexus LS offers a high degree of passive safety for occupant protection in collisions. Lexus has also equipped the LS with technologies that can possibly help prevent crashes from occurring or mitigate their effects.
       
      The LS will feature the brand’s Lexus Safety System + and offer the Advanced Safety Package, which features the world’s first system with Intuitive Pedestrian Detection with Active Steering within the lane. With this system, if a pedestrian is detected in the lane ahead and a collision is imminent, the LS is designed to automatically brake and potentially steer around the person while staying in the lane. The available color HUD is utilized in alerting the driver.

      With the All-New 2018 LS, Lexus Reimagines Global Flagship Sedan
      Radical new design with coupe-like silhouette, yet spaciousness of prestige sedan New platform for greatest-ever LS agility and comfort All-new twin-turbo V6 with 415 horsepower 10-speed automatic transmission All-new available Lexus Advanced Safety Package New level of flagship luxury in every aspect Interior inspired by traditional Japanese aesthetics On sale in U.S. near the end of 2017 DETROIT, January 9, 2017 — It is possible that no single automobile has, upon introduction, upended its category as decisively as the first Lexus LS did when it launched the luxury brand 28 years ago. The 1990 LS 400 was the original luxury disruptor, winning critical acclaim and astonishing customers by setting new benchmarks for comfort, powertrain performance and smoothness, quietness, build quality, attention to detail, and dependability. The brand supported that groundbreaking vehicle by setting and maintaining new standards for customer service and satisfaction.
       
      Now, Lexus is about to repeat history with the introduction of the all-new, fifth-generation LS flagship sedan for 2018, unveiled at the 2017 North American International Auto Show. Inside and out, the new LS reflects a strong, uniquely Japanese identity and approach to luxury. Yet, the LS was designed to be the brand’s latest global citizen, available in about 90 countries.
       
      “Not only will the LS symbolize the Lexus brand, it will become the definitive new-generation luxury car embodying Japanese tradition and culture,” said Toshio Asahi, chief engineer for the new LS. “As such, this global pinnacle must go far beyond what the world expects from a luxury car.”
       
      Longer, Lower, Wider – and More Exciting
       
      Longer and lower than the sedan it replaces, the all-new LS debuts a strikingly bold design with a coupe-like silhouette punctuated by the Lexus design language. A new driver-centric performance feel comes from building the LS on the company’s all-new global architecture for luxury vehicles (GA–L). This premium rear-wheel drive platform, an extended version of the one used for the stunning new Lexus LC 500 coupe, will offer a more dynamic experience on the road while further elevating renowned Lexus comfort. 
       
      The original Lexus LS won acclaim by anticipating what luxury customers would want, rather than simply amplifying what established luxury automobile brands offered at the time. In that spirit, the 2018 LS sedan’s spacious cabin, unique appointments and visionary technology will once again surprise customers by resetting expectations for a global flagship sedan.
       
      “We set previously unheard of targets and resolutely pushed ahead towards these ambitious goals,” said LS chief engineer, Asahi. “The customers who are going to want to own a Lexus flagship are already surrounded by luxury on a daily basis, people who have a sharp eye for authenticity to begin with. We wouldn’t turn their heads with a conventional premium product.”
       
      A Flagship Reborn
       
      Just as the original LS launched the Lexus brand, the all-new 2018 LS continues the brand’s more dynamic direction. Each generation of LS sedans leading up to this iteration advanced luxury, craftsmanship, performance and safety in their own way, with the most recent also introducing a far more emotional design and engaging on-road performance.
       
      To create the all-new LS, Lexus took the approach of starting from new, reimagining what a flagship sedan should be, as if launching the brand all over again. The goal was not to improve on what Lexus has done, but to exceed expectations of global luxury customers.
       
      A common thread going through all LS models remains: Omotenashi, the concept of Japanese hospitality. Applied to a luxury automobile, it means taking care of the driver and passengers, anticipating their needs, attending to their comfort and helping to protect them from hazards.
       
      Vehicle Dynamics
       
      More than ever before, luxury sedan drivers demand greater handling agility and performance feel without sacrificing comfort. It’s one of the most difficult balances to achieve in a vehicle, yet the new Lexus global architecture for luxury vehicles (GA–L) meets the challenge. The new platform debuted in the LC 500 coupe and now, with a longer wheelbase, underpins the new LS. To enhance center of gravity height and weight distribution, the new LS has a wide and low design.
       
      The GA-L platform is the stiffest in Lexus history, setting the stage for enhanced handling, ride smoothness and cabin quietness. The 123-inch wheelbase is 1.3-inch longer than the current LS long-wheelbase model.
       
      Helping to provide the uncanny ride and handling balance in the new LS is the latest generation of a chassis control technology known as Vehicle Dynamics Integrated Management (VDIM). This system implements cooperative control of all vehicle subsystems – braking, steering, powertrain, and suspension – to control basic longitudinal, lateral and vertical motion as well as yaw, roll and pitch. Optimal control of these motions helps to enable exceptional ride comfort, enhanced traction and safety and handling agility. Handling can be further enhanced by active stabilizer bars and the Lexus Dynamic Handling (LDH) System with independent front and rear steering. VDIM is capable of aiding stability when the car is traversing split-friction surfaces, such as dry pavement and ice.
       
      In creating the new LS, engineers used lightweight materials including ultra-high tensile steel sheet and aluminum to carve over 200 pounds from the current LS platform and body. These savings, along with the implementation of the new V6 engine and enhanced body rigidity, allow for a more dynamic driving experience. 
       
      Critical to its driving performance, the new platform lowers the car’s center of gravity by placing most of the mass, including the engine and the occupants, in a position more centralized and lower in the chassis. Special braces in the engine compartment, stiff aluminum front and rear suspension towers, and other features help bolster the strength of key chassis structures.
       
      The LS has a history of outstanding suspension compliance, yet Lexus saw opportunity for new gains in this realm as well. For example, the multilink suspension employs double ball joints on the upper and lower control arms to help allow for control of the smallest movements from the driver inputs and road conditions. Beyond sharing workload, a dual ball joint arrangement helps optimize suspension geometry to increase wheel control and yield more precise steering response with better initial effort. To reduce unsprung weight and therefore aid agility and comfort, aluminum is used extensively in the suspension.
       
      LS Performance and Smoothness Redefined: Twin-Turbo V6 and 10-Speed Transmission
       
      For both high power and excellent fuel efficiency, Lexus designed an all-new 3.5-liter V6 engine specifically for the new LS with all-new twin turbos developed through the company’s F1 technology. This new engine in the LS is indicative of the more dynamic approach being taken by Lexus, offering V8-level power without sacrificing fuel economy—all while minimizing noise and vibration. The new LS engine offers the output one would expect in a flagship sedan: 415 horsepower and 442 lb-ft of torque, sizeable gains over the current LS model’s V8. The long stroke and optimized stroke-to-bore ratio contribute to high-speed combustion and the efficiency of the twin turbos, which assist the LS with a projected 0-60 time of 4.5 seconds (RWD).     
       
      Perhaps more critical is how Lexus tuned the engine and transmission to deliver instant acceleration and a constant buildup of torque toward the engine’s redline.
       
      A ladder frame structure in the cylinder block, redesigned engine mounts, electric wastegates and numerous other features help ensure the remarkable powertrain smoothness, a Lexus hallmark. The driver will be able to tailor powertrain response and feel by choosing from Normal to Sport to Sport+ modes, and just enough of the exhaust note can be heard to enhance the sporty feel.
       
      The first-ever 10-speed automatic transmission for a premium passenger car, having already debuted in the Lexus LC 500, is also used in the new LS flagship sedan. It is a torque-converter automatic, yet with shift times that rival those of dual-clutch transmissions. The wide bandwidth afforded by ten closely spaced ratios is ideal for all forms of driving, helping to provide an optimal gear for all conditions.
       
      Shifting via paddles is available, yet many will prefer the advanced electronic control system, which anticipates the driver’s input. The system chooses the ideal ratio by monitoring the acceleration, braking and lateral-g forces.
       
      For starting acceleration, the close ratios of the low gears and the shortened shift time enable a rhythmical and exhilarating acceleration feel. The high torque of the twin-turbo engine matches ideally with the higher gear ratios for effortless, serene highway cruising, yet very quick downshifts yield direct acceleration with no lag in G response.
       
      Torque converter lock-up activates in all ranges except when starting off to provide a direct feel, while also supporting fuel efficiency.
       
      Crafting a Unique Identity
       
      “The LS is the flagship of the Lexus brand,” said chief designer, Koichi Suga. “More than any other model, it embodies the history and image of Lexus and serves as a symbol for everything the brand stands for.”
       
      Following the “Yet” philosophy that has been passed on since the first-generation LS, Lexus created a design offering the room and comfort of a prestige “three-box” sedan, yet with the stylish silhouette of a four-door coupe that holds stronger appeal for younger luxury customers.
       
      Lexus designers took full advantage of the new platform, with its lower profile and length on par with that of a prestige long-wheelbase sedan, to give the new LS a stretched, ground-hugging appearance. Compared to the current LS, the new model is about .6 inches lower, while the hood and trunk are approximately 1.2 inches and 1.6 inches lower, respectively. The new LS is the first Lexus sedan with a six- side window design. Also a first for a Lexus sedan, the flush-surface windows smoothly integrate with the side pillar.
       
      To preserve headroom with the lower profile, the new LS features an outer slide-type moonroof. The unique rendition of the spindle grille mesh, with a texture that seemingly changes in different light, is the result of both intense CAD development and hand-adjusting thousands of individual surfaces.
       
      The LS debuts five wheel designs, including two new 19- and three 20-inch wheel designs. The 20-inch premium wheels employ a brilliant appearance created using an electroplating technique known as sputtering. All but one of the wheel designs feature a hollow rim structure that helps reduce the resonance sound generated by the tires.
       
      Progressive Comfort with Traditional Inspiration
       
      Creating a new standard of flagship luxury is not simply a matter of adding more features. Inspired by the omotenashi principle, Lexus sought to instill the new LS cabin with luxury that welcomes and envelops the occupants while treating the driver like a partner.
       
      “I suggest that you simply open the door and experience that immediate, intuitive sense that you’re looking at an interior that is unlike any luxury car before,” said chief designer Suga.
       
      New seating designs, including available 28-way power front seats that feature heating, cooling and massage, exemplify this approach. The organically shaped dash design clusters information displays at uniform height to support the “seat-in-control” layout that emphasizes the driver’s ability to operate all systems without the need to change posture.
       
      While making the new LS even more of a driver’s car, Lexus also lavished attention to the rear seat, developing a design that creates seamless, enveloping continuity between the trim and seatbacks for passenger egress.
       
      Options for heating, cooling and massage make the rear seat a welcoming environment. The available power front and rear seat with Shiatsu massage and a raised ottoman, part of a wider rear seat luxury package, offers the most legroom of any previous-generation LS. In addition, the seat behind the front passenger in this optional package can be reclined up to 48 degrees, and can be raised up to 24 degrees to help assist the rear-seat passenger in exiting the vehicle.
       
      Because the new LS is lower than previous versions, Lexus, for the first time, equipped the available air suspension with an access function. Activated by unlocking the car with the smart key, access mode automatically raises the vehicle and opens the seat bolsters to welcome drivers behind the wheel.
       
      The Intersection of Tradition and Technology
       
      Lighting and attention to detail express a unique aesthetic in the LS. A new approach to creating trim elements again turned to Japanese culture, combining traditional Japanese aesthetic with advanced manufacturing techniques. This is reflected in signature touches, such as beautiful interior ambient lighting inspired by Japanese lanterns and armrests that appear to float next to the door panel.
       
      Inspired by Shimamoku wood patterns, the new forms that combine the artistic combination of natural woodwork and application of Japan’s sophisticated sliced wood and laser cutting manufacturing technologies can be seen in the new LS. New patterns include Art Wood Organic, Art Wood Herringbone, and Gray Sapele Wood with Aluminum. Compared to the straight-grain Shimamoku pattern, the new LS cross-grain is a larger pattern featuring bolder contrasts between light and dark, giving the wood a more vibrant appearance.
       
      The Sounds of Near Silence – or Great Music
       
      Lexus tuned the LS exhaust to convey a more authoritative tone, yet also designed the cabin to ensure utterly quiet cruising. New sound suppression methods further hush the environment compared to previous LS models. Active Noise Control quiets the cabin even more by detecting the sound of the engine coming into the vehicle and cancelling certain frequencies using antiphase sound from the audio speakers.
       
      The serenity of the LS cabin provides an ideal stage for the standard premium audio system or the audiophile-worthy available 3D surround Mark Levinson audio package with in-ceiling array speakers. The package features a more inviting graphic user interface. Its next-generation remote touch is designed to mimic smartphone operation, also supporting handwritten input. In addition to its 12.3-inch wide navigation display, the LS can incorporate an optional 24-inch color heads-up display (HUD)—the largest in the world—that projects a variety of information onto the driver’s forward view.
       
      Advanced Safety Features and Driver Support
       
      Structurally, the all-new Lexus LS offers a high degree of passive safety for occupant protection in collisions. Lexus has also equipped the LS with technologies that can possibly help prevent crashes from occurring or mitigate their effects.
       
      The LS will feature the brand’s Lexus Safety System + and offer the Advanced Safety Package, which features the world’s first system with Intuitive Pedestrian Detection with Active Steering within the lane. With this system, if a pedestrian is detected in the lane ahead and a collision is imminent, the LS is designed to automatically brake and potentially steer around the person while staying in the lane. The available color HUD is utilized in alerting the driver.
