New York 2018: 2019 Cadillac XT4 Kicks Off A Product Renaissance: Comments

Recommended Posts

Posted (edited)

It's encouraging that GM has developed a new motor here but the power specs are not as encouraging. If the torque band is lower and more punchy then I hope that bears it out. They could be releasing the all new engine in lower tune to make sure it doesn't self destruct, or it's the guinea pig for real world durability testing before it gets rolled out to other models within GM. The mpg doesn't look like it benefits from the detuning so we will just have to see what the deal is when the vehicle actually hits the street. Usually new motors match their old specs and even can improve on mpg and reliability without any detuning.

GM already has a 2.0 turbo 4.  Isn't this the same thing already in many GM models ?  Odd that it would be 237hp in the XT4, since it is already 250-275 hp in other models.

How can the CTS be 196 inches long and have a small back seat?

The exact same way the e-class has a small back seat.

We really need to dispense with the horsepower as a benchmark thing. It's not doing any of us any favors to be fixated on it. Lots of torque, way down low, is the best, way to go.

True but the current 2.0 is rated as high as 295 lb ft in some applications.  The new mill doesn't crank that amount out either.

No I think this engine is new.

I wonder why they would do an all new 2.0. What would be the point.

Clean sheet redesign to improve a number of engineering aspects, in all likelihood. Cadillac's not wasting money here.

Ironically, they did the exact same thing in the '60s; the '63 390 was completely redesigned but came out with the same displacement. I believe there a major component of the redesign was to allow larger future displacements, but there were other criteria.

I want to see lighter interior tones and better lighting. There was probably very little breathing room for this debut. 

 

I think the XT5 has a light brown interior option on some trims right? Where the dash, pillars, seats and doors are light brown. That is a good interior, I want to see the XT4 version of that.

This will actually be the third all-new 2.0t from GM. This new one has AFM.

As we see displacements congeal around even numbers, we'll see this happen more often.

Plastic on the rear bumper yeah, not all over the place.  The Q5 has way less plastic on it than an XT4.  And if Cadillac has an exclusive 4 cylinder (which is sort of a waste of R&D dollars unless it runs super quiet or something) why does it make less power than an Chevy 4-cylinder?

Cadillac has 258 lb-ft at 1,500 rpm?

Mercedes GLC makes 273 lb-ft at 1,300 - 4,000 rpm

BMW X3 makes 258 lb- ft at 1,450 - 4,800 rpm

Audi Q5 273 lb-ft at 1,600 - 4,500 rpm

Not surprised by who has the most torque at the lowest RPM

i believe i read where it said this the AFM allows it to run on two cylinders?

if an engine is redesigned, it can possibly be

-lighter or smaller to fit in engine bay easier

-simpler

-cheaper

-easier to manuf.

-incorporate new technologies

-more power

-better mpg

Could be. The new V8 can run on as few as one cylinder in a revolution.

There were engineering reasons for that. They added balance shafts to smooth out the previously rough engine.  Once they got that sorted out they started increasing hp again.

Also, about 10 years ago...

"In December 2008, GM released a Turbo Upgrade Kit for the LNF engine which increases horsepower to 290 hp (220 kW) and torque to up to 340 ft⋅lb (460 N⋅m), depending on the model. The kit retails for $650 and includes remapped engine calibration and upgraded MAP sensors. The kit is covered by the cars' existing GM warranties."

And before you try to play the CLA/GLA43 card SMK... It took MB 10 years to catch up to and exceed the power output of a 2008 Cobalt SS.

A tuning decision is a tuning decision. It is not a indicator of engineering ability when a company has already proven itself able. 

Power delivery also matters and nearly every review of the CLA complains of turbo lag. So a fat lot of good that extra lb-ft is doing when it takes an extra 3 clicks of the mouse to get it.

Everything else you said is probably spot on but there is no simpler engines being made anymore. Everything is more and more complex.. you even mentioned the ability to run on 2cyl..lol

I know you can tune an engine to any power level (within reason) but reliability and NVH go out the window if you extract more power than you should from an engine.

I have never driven a CLA, so I don't know what the turbo lag is like, but the M270 has a twin scroll turbo and makes 258 lb-ft @ 1,200 rpm so I can't imagine it is that bad.  And the M274 which is the sister engine to the CLA used in the C-class and GLC has very little lag and you don't really notice the turbo at all plus it won a Ward's 10 best engine award in 2017.

375 hp/350 lb-ft now.  And that is probably going up in 2019 with the new A-class line.  Although I think it pointless to increase it.  If you want more power buy an AMG C-class.  Interesting thing is they are planning an A35 with like 300 hp which could be a sweet spot for that car.

Read my post after that.  GM was doing 340 lb-ft from a 2.0T 10 years ago. 

With a post-purchase modification. From GM or not. That's like saying the EcoBoost Mustangs are 335hp and 390 lb-ft with the Ford Performance tune for only $699. 

Depending what you want to believe from Ford...

They're still only FWD, right?  

They already probably have some trick system to get power down but upping that more they're going to have to re-configure that out too.

The NVH of the old 2.0T in the Cobalt was actually pretty good for its day. 

Again, you don't need to take my word for it... look at all the articles regarding the turbo lag in that car

AutoWeek - CLA Turbo Lag - Whether sport or economy mode is selected, the Mercedes always seemed to be a half-gear shy of where it should have been, and the combination of turbo lag and wonky clutch take-up makes smooth low-speed driving difficult. Once on the road there's plenty of power to get into trouble, so it's not a fundamental output issue -- rather it's a lack of refinement between the engine and transmission. 

Cars.com - CLA Turbo LagDespite the turbocharged four-cylinder engine's stout 208 horsepower and 258 pounds-feet of torque, excessive drivetrain lag sullies the CLA250. A sustained toe on the gas can induce gratifying low-end punch, where the little Benz surges ahead even at 2,000 rpm. The problem, however, is getting to all that.

MercedesBlog.com CLA AMG45 Turbo Lag - To obtain the high power of 381 HP and the high torque of 475 Nm, relatively small Mercedes turbo engine operates with a big turbo which delivers a maximum pressure of 1.8 bar. But a big turbo means a high inertia and a big turbo lag which you feel at full throttle.

Car and Driver - GLA Turbo Lag - In its default Comfort mode, sluggish shifts accentuate the engine’s turbo lag

Consumer Reports - GLA Turbo LagBut the seven-speed dual-clutch automatic is unrefined and, combined with the engine's turbo lag, makes the GLA feel lethargic despite its quick acceleration times.

So yea, you could use sport mode all the time, but that will kill your fuel economy.  The reviews above tell me that Mercedes is still a long way off from perfecting this engine into something that is satisfying to drive on a daily basis.  I would be disappointed in Cadillac if the XT4 came out with reviews like what you see above on the GLA/CLA. 

All Cadillac needs to do is tune it similar to the GMC Terrain and they have already beaten Mercedes.

Car and Driver - GMC Terrain Turbo LagOur all-wheel-drive turbocharged 2.0-liter test vehicle achieved the top acceleration figures among its competitive set. Credit the Terrain’s minimal turbo lag and plentiful power, as well as the nine-speed automatic transmission’s ability to drop down a couple of gears quickly with a simple boot of the throttle.

TruckTrend - GMC Terrain Turbo LagWith 252 hp and 260 lb-ft of torque, its output lags behind the 3.6L V-6 that was optional in the previous Terrain, but you’d never know it from behind the wheel, thanks in part to that nine-speed auto. With fleet off-the-line reflexes, minimal turbo lag, and excellent passing power, the 2.0 is a surprising engine to find in the competent—but rarely fun—compact SUV segment. 

 

Mercedes-Benz... the best or is there a GMC in the comparison?

Who cares? It is a dealer installed option fully supported by GM and covered by warranty.  It allows the buyer to choose a higher performance model that would require 92 octane or the more standard SS that can run on regular.  Same goes for the Mustang.   It is functionally the same choice as a CLA 250 or a CLA 43... Benz just makes two models out of it while GM lets you upgrade an existing model. (yes I know there are other upgrades on the 43 over the 250.)

The CLA/GLA problem sounds more from the DCT transmission which I don’t know why they use in the first place rather than the fried and true 7-speed auto that they used from 2003 - 2018, and the 9-speed has replaced it in most cars now.

The GLC and C-class don’t have the lag and acceleration problems, a GLC300 can out accelerate a Terrain, not like it matters in that segment.

Really? You don't know why they didn't use the automatic from the 2003-2018 era?

Put on your deerstalker cap there Sherlock..... maybe you'll figure it out. 

The question was never and is never about raw performance in these crossovers. It is about drivability around town the way 99.9999999% of people use them.  A jumpy, laggy engine transmission combo is not going to be as satisfying as one with low lag and no jumpiness.  

The XT4 will do better than the GLA there and still have plenty of scoot.

I'd assume you're correct but those are just guesses at this point as we're talking transmissions now and nobody has driven this XT4 matched to the brand new engine.

      Back at the New York Auto Show, Cadillac unveiled an all-new twin-turbo 4.2L V8 that produces 550 horsepower and 627 pound-feet of torque. This engine was destined for upcoming CT6 V-Sport. But with the CT6 lineup destined to go away in the near future, what will happen to the new V8.
      Roadshow has learned from a source that Cadillac will be using this engine in the next-generation Escalade and CTS-V (don't you mean CT5-V?!).
      Let's begin with the next-generation Escalade. The current model uses a 6.2L V8 engine that makes 420 horsepower and 460 pound-feet of torque. We know that Cadillac was planning to offer a slightly detuned version of the 4.2L V8 on the regular CT6, producing somewhere in the range of 500 horsepower. Whether Cadillac decides to go with this or push power down a bit further remains to be seen.
      Now to the CTS-V, or CT5-V. This is where we begin to question the source. We know that Cadillac will be retiring the CTS and ATS in the next couple of years for the upcoming CT5. Why the source said, "next-generation CTS-V sedan" has us scratching our heads. Maybe the source misspoke or GM is thinking about continuing forward the CTS-V nameplate. We're likely putting too much thought into this.
      Nevertheless, we would expect Cadillac to bump up horsepower to 600 or so to keep up with the likes of the Germans.

      A few weeks back, I attended an event at Hyundai’s technical center which resides outside of Ann Arbor, Michigan. The reason for my visit was to get a preview of what they’ll be showing at the LA Auto Show (which I’ll be able to talk about later today once the NDA lifts). But Hyundai also offered the chance to drive some of their latest products on a small drive route. I had the chance to drive three models; the Santa Fe, Kona, and Veloster. 
      A quick note about this first drive report. You will not get any impressions on the handling of the three models. The short drive was mostly made up of straight roads around the technical center. You’ll need to wait until I can my hands on the vehicles for a week-long evaluation to see how they fare in the bends.
      First up is the Santa Fe.
      I’m quite impressed with the work done on the Santa Fe’s exterior as it has much more presence on the road than the Santa Fe Sport it replaces. The square shape is accentuated by a more aggressive grille and a more upright rear end. One downside to the new look is the raised belt line, which reduces the overall glass area and makes the interior feel slightly cramped. Step inside and Hyundai has taken a huge leap forward here. A lot of their current interiors tend to focus more on utility and having controls in easy reach. The Santa Fe adds a bit of style with rounded edges, sculpted sides for the driver and passenger, and brushed metal accents. One nice touch in the Ultimate is a contrasting roofline that looks and feels like a piece of soft linen. One item that hasn’t changed is the controls. They are still easy to find and operate. The front seats are quite comfortable and offer a number of power adjustments to help dial in the perfect position. The rear seat is massive with loads of head and legroom, even with the optional panoramic sunroof. A 2.4L four-cylinder with 185 horsepower serves as the base engine, while a more powerful 2.0L turbo-four pumping out 235 horsepower is available on the higher-end Limited and Ultimate. An eight-speed automatic is standard on either engine, and you do have the choice of either front or Hyundai’s HTRAC all-wheel drive system. I drove the turbo-four with AWD and found it to be a bit underwhelming. The issue is the noticeable delay with power delivery when leaving from a stop or accelerating suddenly from a low cruising speed. I can’t fully tell if this due to the tuning of the engine, transmission, or combination of the two. It is quite the shame because the engine really shows it has punch when making a pass.  Ride quality is towards the top of the class as the suspension is able to smooth out most rough road surfaces. Road and wind noise are well-muted. There’s a lot to like about the 2019 Santa Fe with its new look inside and out; spacious interior, and smooth ride. The turbo engine does sour my initial impression and has me wondering if you should wait a year until picking the turbo engine. Those who have driven the 2.4L say the engine is slightly sluggish, but I would take that over the mess that is the turbo-four.

      Mazda's 2019 3 compact sedan and hatchback were introduced last night at the LA Auto Show and it is clear the brand is not messing around. The latest-generation compact introduces a new platform, the Skyactiv-X compression ignition system, and the option of all-wheel drive.
      The 3's exterior shape sheds a lot of the sculpting and surfacing found on the current model. The end result is a smooth and premium look. Both the hatchback and sedan come with the same creased front end, prominent grille, and slim headlights. The hatchback is the more polarizing of the two with a very thick c-pillar from the Kai concept. On the inside, Mazda's designers have taken some inspiration from their recent concepts by going for "less is more" aesthetic. The dashboard is mounted low and features a minimal amount of buttons. An 8.8-inch infotainment screen sits in a crevice in the dash and appears to be running a new infotainment system (THANK YOU MAZDA!).
      In North America, Mazda will be offering the 3 with an updated version of the 2.5L SkyActiv-G four-cylinder. No power ratings were given on the engine, but we wouldn't expect them to be too far off from the 184 horsepower and 185 pound-feet of torque that engine currently produces in the CX-5 and 6. This will be paired with either a six-speed manual or automatic. Other markets will get the choice of 1.5L, 2.0L, 2.5L, and 1.8L diesel.
      Mazda's SkyActiv-X four-cylinder with compression ignition will launch later down the road. We don't have any details on power or what transmissions can be paired with it.
      One option that will make some buyers happy to see is i-Activ AWD. This system uses a number of sensors around the vehicle to help keep the vehicle moving in any condition. Mazda doesn't say which engines will have the AWD option, but we think the 2.5 will be one of them.
      Mazda says the 2019 3 will launch early next year with the 2.5 engine. The SkyActiv-X engine will arrive towards the end of 2019.

      ALL-NEW MAZDA3 – AN OBJECT OF UNIVERSAL DESIRE
      As we begin a new chapter in Mazda’s history, the mission of the all-new Mazda3 is to amaze and delight customers all over the world. The theme of development was “An object of universal desire.” Making a car that would evoke longing in any person would require the creation of a new, hitherto unknown value. We set out to achieve this by applying our human-centric philosophy for dramatic improvements in every area: design, driving performance, NVH, environmental performance and quality feel.
      The all-new Mazda3 embodies two characters with widespread appeal. The first is the free spirit, determined to follow their own convictions and not be bound by conventional wisdom. This character is represented in the hatchback. To achieve such a look we took an unprecedented approach to design that eliminates all character lines and relies entirely on lustrous and beautifully curved body panels that reflect the surrounding environment. As such, the model delights onlookers with a countenance that changes by the season and the hour of the day.
      The other character is that of a lady or gentlemen who combines dignity with a strong individualistic streak. Their adherence to formality and traditional styles conceals an idiomatic beauty that is breathtaking when glimpsed. This character is embodied in the sedan. Aspiring to create the most gorgeous sedan in its class, we set aside the notion of a C-segment car,* removed all constraints and extended the overall length. We overcame numerous technical challenges in order to keep the hood and trunk low. The resulting proportions are sleek and elegant, giving the impression of a single flowing brushstroke.
      We also raised the quality of driving and riding in the car. Driving an automobile requires paying constant attention to your surroundings, making split-second judgments and taking appropriate action. Mazda wants to make driving less stressful and more natural for everyone. To achieve this, we decided to undertake a thorough scientific study of human beings.
      When walking or running, people make subtle adjustments in the legs, pelvis and spine so that head sway can be controlled using only the slightest muscular effort. In order to make this natural action possible in the car, we redesigned and organically linked every component to draw out people’s innate ability to maintain balance. The result is Skyactiv-Vehicle Architecture, a new set of structural technologies that make riding in a car feel as natural and stress-free as walking on your own two feet.
      In addition, we achieved a comfortable quietness by focusing not only on noise volumes but on the time it takes for sounds to be transmitted and the direction from which they arrive. Next, we built a clear and expressive sound system with speakers positioned to deliver sound directly to the driver’s ears and set about creating a comfortable cabin space for all vehicle occupants.
      Thanks to the benefits of Skyactiv-Vehicle Architecture and the latest Skyactiv gasoline and diesel engines, which allow intuitive control of vehicle speed in any situation, the all-new Mazda3 offers driving pleasure of unprecedented quality.
      The powertrain lineup includes Skyactiv-X, a new kind of combustion engine that combines the advantages of gasoline and diesel engines. Its innovative Spark-Controlled Compression Ignition system enables us to choose gear settings that accentuate performance without sacrificing emissions or fuel economy. Engine response is quick and driving is smooth with a reassuring feeling of control. Skyactiv-X will realize even greater driving pleasure and superior real-world environmental performance, enhancing the joy the car-ownership.
      The all-new Mazda3 will add color and brilliance to your daily routine. The captivating character of the design stirs the emotions and the driving feel sharpen the senses, making even your daily commute feel like a journey of new discovery.
      My hope is that this car will help customers discover the joys of living a life truer to oneself.

      A NEW FORM OF ELEGANCE BASED ON JAPANESE AESTHETICS. MAZDA DESIGN ENTERS AN EXCITING NEW STAGE.
      Introduced in 2010 and making its production model debut with the launch of the CX-5 and the Mazda6 in 2012, Mazda’s Kodo—Soul of Motion design has been a driving force in enhancing the brand’s global value. Mazda now takes it to higher levels of depth and sophistication as it enters a new stage that raises car design to the level of fine art.
      The goal for this new evolution of Kodo design is to express a new form of elegance inspired by Japanese aesthetics. The first cars to embody Mazda’s new design language were the RX-Vision concept model shown at the 2015 Tokyo Motor Show and the Vision Coupe concept model exhibited at the 2017 show. Elements finely honed to create clean, beautiful designs combine with a delicate play of light and reflections to realize elegant and sophisticated styling with a natural, dynamic feel.
      The new Mazda3 is the first production model to adopt this evolved version of Kodo design. While featuring an extremely simple “single motion” to its overall form, the way light and shadows shift and reflections move over the body gives birth to a highly vital and dramatic expression that goes beyond previous iterations of the design language. Another goal in styling the new Mazda3 was to give the hatchback its own more emotional design, while the sedan aims to present more elegant proportions. Despite sharing the same Mazda3 model name, the two forms represent entirely different personalities.
      EXTERIOR DESIGN
      In designing the hatchback and sedan versions of the new Mazda3, the development team took a fresh look at their respective values and personalities and then worked to maximize the unique appeal of each. The hatchback presents a powerful and seductive look with lasting visual appeal that evokes a sense of exciting experiences to come. In contrast, the clean, sleek and sophisticated beauty of the sedan speaks of maturity and refinement. The result is two body types with personalities so distinct one might even think they were completely different models.
      The design concept for the hatchback focused on creating a solid mass with a seductive appeal that conveys a fresh expression of hatchback styling. When viewed from the rear, the cabin and body come together to appear as a single solid mass. This unique form realizes a powerful, solid presence and an expression of seductive and lasting appeal. The design concept for the sedan is “sleek and elegant.” While conforming to traditional sedan styling by bringing together the hood, cabin and trunk as three distinct elements, the development team aimed to elevate those elements and achieve a new level of beauty that befits a Mazda sedan. The result is a refined, mature expression of elegance. A new lamp design is one more element key to Kodo design’s further evolution. In keeping with the “less is more” theme, all unnecessary elements are shaved away to leave only the essence of a lighting fixture. The development team felt that limiting the design to the minimum necessary elements – the light source, lens and base – would create a clean and beautiful look. They also pursued a round design with an expression of depth in order to create a presence that accentuates the new Mazda3’s physique and fore-aft axis. The new design embodies a dynamic expression that distinguishes the Mazda brand. Polymetal Gray was newly developed as an exclusive color offering for the hatchback. Fusing the hard appearance of metal with plastic’s characteristic glossy smoothness creates an entirely new expression of quality. The color changes its expression depending on the light, accentuating the beautiful form of the hatchback’s body. INTERIOR DESIGN
      To further strengthen the connection between the car and driver, every aspect of the cockpit is laid out in perfect horizontal symmetry with the driver in the center. At the same time, every element is designed to directly face the driver and help emphasize the driver-centered axis that runs from front to rear. Furthermore, the interior incorporates the “less is more” ideal that is a key to the new Mazda3’s further-evolved KODO design. Keeping all elements other than the cockpit as simple as possible helps amplify the presence of the cockpit zone. This creates a comfortable environment in which the car and driver engage in a natural dialogue that enables the driver to focus on the task of driving.
      The cockpit design applies the “vanishing point” concept down to the parts level, including the steering wheel spokes and center display. Along with emphasizing the driver-centered axis running from front to rear through the cockpit zone, this design approach also expresses a second horizontal axis through the layout of the forms that run left and right from the instrument panel out to the door trim on both sides. The design goal was simplicity throughout based on the aesthetics of “less is more.” For example, the climate-control panel and passenger-side louvers are integrated into the left-right axis that follows the line of the instrument panel. This results in a clean and simple design. Interior parts employ Mazda’s own grain, designed to express the richness and warmth of genuine leather. By introducing creases with differing depth and shapes on different parts, this new material creates a lively rich expression. The newly designed shift panel takes advantage of a technology called “two-layer molding.” It incorporates a laser-engraved black layer covered by a second clear layer to present a glossy black finish with a look of deep transparency. Shifts in light create a rich linear expression that helps the panel accentuate the new Mazda3’s sporty nature, high-quality appearance, and pride of ownership. The fabric interior adopts a new Greige color, which combines the cool tones of gray with the soft feel of beige to create a pleasing sensation of vitality and warmth. This combination of light and depth gives the interior a sophisticated look. Burgundy was newly developed as an interior color exclusive to the hatchback. The deep, vivid look of this special red leather heightens the emotion of exterior design and creates a look that appeals to mature tastes. HUMAN-CENTRIC DESIGN FURTHER ENHANCES RELAXING COMFORT
      The cockpit and cabin were carefully designed in accordance with Mazda’s own human-centric philosophy. One goal was to provide all drivers with a confidence-inspiring ease of operation that helps them to concentrate on driving. Another was to make time spent in transit comfortable and enjoyable. Mazda applied the latest available knowledge and technology in designing the driving position, visibility, Human-Machine Interface (HMI), and audio sound quality. These were leveraged to further elevate the level of quality and satisfaction by delivering a more natural and intuitive feeling to driving. The new Mazda3 provides all occupants with the pleasure of a natural, comfortable and relaxing driving experience that begins with the very first outing and remains consistent in any driving scene.
      DRIVING POSITION
      The telescopic steering adopts an additional 10mm of movement at either end to offer a wider adjustment range of 70mm and deliver more precise control over the adjustment of the driving position. In addition, front seat cushion tilt adjustment is now included as standard equipment. This helps prevent the angle of the seat from causing the occupant’s thighs to float above the cushion or placing undue pressure on the thighs. As such, it offers firm support that keeps the pelvis in an upright position to maintain the ideal seating posture Mazda has strived to achieve. The gear shift lever was moved forward and positioned higher on both the automatic and manual transmission versions. This makes it easier for the driver to move his or her hand from the steering wheel and to operate the shift lever. The commander control was also moved forward, the cupholders repositioned in front of the shift lever and the center armrest lengthened. This new floor console layout significantly improves operating stability, ease and use. HUMAN-MACHINE INTERFACE (HMI)
      The Active Driving Display, meters and center display were all redesigned to present information in a simpler fashion, while the fonts used were unified to create a pleasing and consistent look. The new Mazda3 adopts an 8.8-inch wide center display. Offering simplified operation that requires only the use of the commander control, it also features a new intuitive guidance system that makes the commander control easier to operate. VISIBILITY AND FIELD OF VIEW
      The thickness and shape of the A-pillar design were optimized to minimize its obstruction angle and associated blind spots. Every detail of the pillar shape was carefully designed after calculating what degree of neck and eye movement would not burden the driver. As a result, the new design significantly reduces blind spots ahead of the car, providing the driver with a continuous view of pedestrians or potential obstacles to the right or left while maintaining a natural driving posture. The control system for windshield wiper operating speed was carefully designed to improve wiper performance. It is also designed to constantly adjust the operating angle of the wipers in fine increments. This allows them to firmly clean right up to the A-pillar and greatly expand visibility near the A-pillar on the driver’s side. The wipers are housed beneath the hood, which helps provide a clear downward view out of the windshield. In addition, the washer nozzles are attached to the wiper arms so their spray can be wiped away immediately after application and not interfere with visibility. These measures combine to provide the driver with a clearer view and to more quickly maintain clear visibility in inclement weather. MAZDA CONNECT
      Mazda Connect now includes a Digital Owner’s Manual as one of its app offerings. When a warning appears on the center display, it also presents an indication of the priority level and a link to the Digital Owner’s Manual. The driver can then access the manual to quickly receive an explanation of the warning and instructions on how best to respond to the situation. AUDIO SYSTEM
      Mazda conducted a series of new studies into how sounds are transmitted through a car’s cabin. This led to more efficiently improving sound quality by placing the bass speakers in the corners where the sound is amplified. To avoid the tonal quality of mid- to high-frequency sounds from being affected by reflected sounds, the other speakers were positioned on the left and right sail garnish and upper sections of the door trim where the sound is transmitted directly toward the occupant’s ears. This creates a more natural sensation to distinguishing the sound’s point of origin and enhances the depth and clarity of that sound. The 8-speaker standard audio system uses a 3-way layout, with 3L woofers positioned on the sides of the front cowl, a pair of 2.5cm squawkers on the sail garnish and 8cm squawkers on the upper section of the front and rear door trim. The 12-speaker Bose®sound system adds an 8cm center speaker, a pair of rear satellite speakers, and a subwoofer. It also features custom tuning to provide more powerful bass and higher audio quality. MAZDA’S NEXT GENERATION OF DRIVING PLEASURE, REFINED AND FURTHER EVOLVED THROUGH HUMAN-CENTRIC DESIGN
      Mazda’s Jinba-ittai driving experience demands that the car works in perfect harmony with the driver’s intentions to provide greater safety, confidence and reassurance. In working to achieve this, Mazda has remained committed to building cars according to its human-centric design philosophy. These efforts include advancing its Skyactiv technologies. Beginning with the new Mazda3, they also include the introduction of new technologies that further evolve the level to which human-centric design is applied. The ongoing goal is to realize the ultimate expression of Jinba-ittai by enabling the driver to enjoy the pleasure of driving with natural action, as though moving his or her own body without any need for conscious effort.
      These new technologies are founded on intensive human research studies that go beyond just looking at body characteristics and movements by also investigating emotional responses. Rather than simply pursue mechanical efficiency of the human anatomy, Mazda is focusing efforts on maximizing inherent physical abilities while exploring how to realize a driving experience that best matches human sensibilities. By coordinating the development of all these technologies as an organic whole, Mazda honed dynamic performance such that the basic movements of the car – accelerating, turning and stopping – feels natural to the driver.
      The new Mazda3 is powered by the latest Skyactiv engines, including Mazda’s new Skyactiv-X, and also adopts Skyactiv-Vehicle Architecture. This adds a new layer of polish to its driving dynamics, based on Mazda’s human-centric design philosophy. The next generation of Mazda driving pleasure starts here.
      POWERTRAIN
      1.5-, 2.0- and 2.5-liter versions of the latest Skyactiv-G comprise the gasoline engine lineup for the new Mazda3. All three adopt optimized intake ports and piston shape, split fuel injection and a coolant control valve to deliver higher levels of dynamic performance, fuel economy and environmental friendliness. The Skyactiv-D 1.8 is the diesel engine offering for the new Mazda3. Incorporating ultra-high-response multi-hole piezo injectors allows the engine to utilize high-pressure, precisely controlled multi-stage injection. This realizes a finer balance of enhanced fuel economy, quietness and reduced exhaust gases, while also delivering smoother, more robust performance. All-new Mazda3 is the first production car to offer Mazda’s innovative Skyactiv-X engine. Features include superior initial response, powerful torque, faithful linear response and free-revving performance. The engine is assisted by Mazda’s intelligent new M Hybrid system, which supports greater gains in fuel economy, and achieves higher levels of driving pleasure and environmental friendliness. I-ACTIV AWD
      Mazda’s evolved i-Activ AWD newly adds “four-wheel vertical load” detection and works in harmony with G-Vectoring Control Plus (GVC Plus) to control torque distribution between the front and rear wheels. As a result, it is fully capable of responding faithfully to the driver’s intentions, regardless of the driving scene. It also reduces overall mechanical loss by approximately 60% over the previous model and contributes to improved fuel economy. G-Vectoring Control Plus (GVC Plus) adds direct yaw moment control via the brakes. This enables the car to better handle emergency avoidance maneuvers and offers more confidence-inspiring controllability in various situations, including lane changes at high speeds and driving on slippery roads. SKYACTIV-VEHICLE ARCHITECTURE NEXT-GENERATION STRUCTURAL TECHNOLOGIES
      The seats adopt a basic structure designed to maintain the natural S-shaped curve of the spine. The seat cushion and lower seatback support the lower pelvis, upper pelvis and thighs to keep the pelvis in an upright position. Meanwhile, the upper seatback bolsters the gravity center of the rib cage. This structure enables the driver to stabilize his or her head in a natural fashion by shifting his or her pelvis and spine to maintain balance without any conscious effort. The body further evolves Mazda’s straight framework and continuous ring structure concept. New front-to-back connections complement the existing vertical and lateral connections of the previous body to form multi-directional ring structures. This increases rigidity while reducing lag in the transmission of energy, which helps maximize the function of the dampers and tires. By concentrating energy input from the road surface in specifically chosen locations and adopting a newly developed damping structure that helps absorb it, vibration that causes noise is reduced without increasing vehicle weight. Based on the concept of smoothing the transmission of force to the sprung mass over time, the suspension system uses MacPherson struts in the front and a newly developed torsion beam setup in the rear. A new spherical shape was adopted for the internal structure of the bushings combines with new suspension geometry to realize lag-free transmission and linear action. REDUCED NVH
      As a result of Mazda’s human research studies, development focused on three sound characteristics that directly impact cabin occupants. Those are sound volume, changes in pitch and tone over time, and the direction from which sounds originate. Suppressing noise generation and reducing its volume, while also controlling the fluctuations in and direction of sounds, are aimed not only at achieving a “quiet” cabin environment. Rather, the goal is to provide a “high-quality quietness” that is satisfying to all cabin occupants. To improve the basic insulation qualities key to reducing NVH, the new Mazda3 marks Mazda’s first application of a “two-wall” structure that leaves space between the body and carpeting on the floor. By considering the carpet and the body panel as two walls, and then designing them to match the characteristics of the fiber material attached to the carpet increases efficiency without increasing weight. The number of holes in the carpeting was also reduced wherever possible to significantly enhance sound insulation. Measures to deal with road noise focused on minimizing noise and vibrations, and to make any noises transmitted when the road surface changes reach the ears of cabin occupants in a linear fashion. Sound-absorbing functionality added to the headliner and floor mats effectively suppresses high-frequency noise. Tires with optimized vertical spring action and increased rigidity at possible entry points help prevent the transmission of unwanted vibrations to the cabin. Lag-free transmission of permitted sounds and vibrations create a more reassuring and comfortable cabin environment. SAFETY FEATURES DESIGNED TO EXCEL IN THE REAL WORLD
      The fundamental aims of Mazda Proactive Safety are to offer the driver confidence-building reassurance and to offer all cabin occupants a thoroughly enjoyable driving experience. Based on this philosophy, the development team worked hard to evolve basic safety technologies such as the driving position, pedal layout and good visibility, advanced i-Activsense technologies, as well as passive safety technologies designed to protect cabin occupants in the event a collision should occur.
      With an eye on the future, Mazda is constantly making efforts to further evolve the level of safety offered by its cars. The aim is to provide a safe and reassuring driving experience to everybody, from novice drivers with little time behind the wheel, to elderly drivers, and including passengers in the rear seats. Mazda is committed to further advancing its safety technologies as it works step by step toward making car accidents a thing of the past.
      ACTIVE SAFETY: I-ACTIVSENSE
      The new Mazda3 is available with Mazda’s newly developed Driver Monitoring system. The system uses both an infrared camera and infrared LED to observe the driver’s condition while driving. It monitors how wide open the driver’s eyelids are at any given time, the number of times he or she blinks, and also the angle of the mouth and face in order to determine the level of drowsiness or fatigue. It also monitors the driver’s line of sight and eye movement to determine when the driver is being inattentive. If the system judges that the situation has become dangerous, it sounds an alert to make the driver aware and works in conjunction with the Smart Brake Support (SBS) system to shorten the time required for the brake warning to sound. Front Cross Traffic Alert (FCTA) is available on the new Mazda3. The system uses newly adopted front side radars to detect other vehicles approaching from blind spots at the front right or left of the vehicle and alert the driver of their presence. This helps prevent a common cause of accidents, when cars enter a T intersection with a partially obscured view. Also available on the new Mazda3 is Mazda’s new Cruising & Traffic Support (CTS) system. CTS contributes to reducing driver fatigue by assisting with accelerator, brake pedal and steering operations when stuck in traffic jams on the highway. It also supports a safer, more reassuring and more comfortable driving experience in conditions that demand constant operation of the assisted functions. PASSIVE SAFETY
      The ratio of ultra-high-tensile steel rated of 980MPa or higher is greatly increased, from the 3% used on the previous model to 30% on the new Mazda3. This combines with the addition of a new perimeter beam and rear side frames that deform in an accordion-style pattern to create a solid body that can stand up to impact force and a frame structure that effectively absorbs energy. The new Mazda3 introduces a new knee airbag for the driver’s seat. It is not only a first on a Mazda car, but will be included as standard equipment worldwide. By suppressing forward motion of the driver’s body in the event of a collision, this new airbag contributes to fewer injuries to the driver’s legs, chest and Each of the side airbags is divided into a front and rear chamber. Using reduced air pressure in the forward chamber and higher pressure in the rear chamber reduces the load taken by the rib cage, while firmly holding the body in place. The hood adopts a new energy-absorbing inner structure designed to receive the impact of a pedestrian’s head in the initial moment of contact and then gradually dampen the force to more quickly absorb the impact energy. The front bumper is designed to support the thigh and shins if contact is made with a pedestrian’s legs while softening the blow to the knee area. This reduces the degree of injury to the knees and ligaments due to bending and twisting.
