    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.

    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.

    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.

    • At the New York Auto Show this week, Hyundai unveiled the 2025 Hyundai Tuscon.  This mild refresh modernizes the Tuscon and brings it more into alignment with the rest of the Hyundai lineup, including their EVs. The exterior styling updates, largely consisting of a front fascia update, are subtle. Inside, Hyundai made the interior more open and airy with a new, lower-height dashboard featuring a panoramic gauge and infotainment screen. The screens consist of twin 12.3-inch displays with crisper colors and graphics, as well as faster processing speeds.  While the screens can control all functions of the car, Hyundai still included physical buttons for the most frequently used controls.  Wireless Android Auto and Apple Carplay are now standard across the line. A new steering wheel features a much more open design, and on premium trims, the gear selector is now an electronically controlled stalk on the right side of the wheel, much like in the Hyundai Ioniq 6. On some Tuscon models, a new 12-inch color heads-up display with premium graphics is available, and for the first time, navigation directions from Apple Carplay and Android Auto will appear in the display. Proximity key with push button start is now standard across the 2025 Hyundai Tuscon lineup, while an available Digital Key 2 allows for fob-free driving and access via the driver's mobile phone. For 2025, Tucson adds Forward Attention Warning, which utilizes an infrared camera mounted on the steering column to help track the driver’s eye gaze and monitor attention levels to help ensure safe driving. Available Smart Cruise Control 2 continually assesses driver alertness. If the driver is found to be unresponsive, the system can even help safely bring the vehicle to a stop, activating the hazard lights and the electronic parking brake once the vehicle is stopped. Additionally, rear outboard passenger seatbelts now feature standard pretensioners and load limiters. The powertrains largely carry over from the previous model with a standard 187-horsepower 2.5-liter 4-cylinder at the entry level end. Also available is a 1.6-liter turbocharged hybrid with 231 horsepower with a slightly more powerful electric drive unit (47.7-kW, up from 44.2-kW), and a 6-speed automatic transmission. The plug-in hybrid model features the same 1.6-liter unit, but now paired with a larger electric drive unit with 72.0-kW of output rather than the 66.9-kW motor from the prior year. The plug-in hybrid boasts 268-horspower total system power. With a 13.4-kWh lithium-ion battery pack, the 2025 Hyundai Tucson plug-in hybrid takes less than 2 hours to charge on a level 2 charger.  All hybrid models come standard with all-wheel drive. 2025 Tucson 2.5L models will arrive at U.S. dealerships in June, while 1.6L turbo hybrid and plug-in hybrid models will be available late summer.

    • Plastic cladding = off road.  Instead of killing the Sonata, they should just put plastic body cladding down the side and raise the price by $10k and call it the Sonata HD Overlander X.  Instant hit.
    • Considering a planet with 8 Billion and he sold almost 2 million cars, then he is covering .025% of the population compared to other auto companies. I think 2024 going into 2025 we will see other auto companies top Tesla. You and I are two peas in a pod as I also was up on a hill watching the implosion and thinking what a waste as it was a great building. I love the Kingdome and hate the new stadium.  Agree it was surreal to see the ship hit the support pillar and the whole building just collapse. Be interesting to see what replaces it as today bridges built like that are not allowed due to the exact nature of how it collapsed.  Yes, Tesla is a love or hate and the minimalist approach is not for everyone. I honestly have to agree with the comment @smk4565 I believe made that the touch screen only will be the future of cheap autos and switches and buttons will be the higher end autos. Interesting times we live in for sure.
