2016 Cadillac CTS-V Hits 200 mph with 640 hp. Track-capable from the factory, with sophisticated road manners

2016-cadillac-cts-v-artists-rendering-photo-585499-s-1280x782DETROIT – Cadillac today introduced the 2016 CTS-V, the most powerful product in the brand’s 112-year history and the newest entry in the elite class of the world’s highest-performing luxury cars.

Launching in late summer with 640 horsepower (477 kW), 630 lb-ft of torque (855 Nm) and a top speed of 200 mph, the new CTS-V reaches higher than its predecessors, leading Cadillac’s product-driven expansion and elevation. It is the third generation of the acclaimed luxury sports sedan that launched the elite V-Series a decade ago – and redefined Cadillac for a new generation of enthusiasts.

“V-Series represents the very best of the Cadillac brand – the pinnacle of our design and technical capabilities,” said Johan de Nysschen, Cadillac president. “The new CTS-V is the most compelling example of Cadillac’s product substance and brand trajectory. The new CTS-V soars into the stratosphere of the most exhilarating luxury cars.”

Comprehensive updates make the new CTS-V essentially two cars in one: a luxury sedan with sophisticated road manners and a track-capable sports car straight from the factory. It also introduces a new supercharged 6.2L V-8 engine backed by Cadillac’s paddle-shift eight-speed automatic transmission, featuring launch control and Performance Algorithm Shifting.

With more horsepower and torque than the Mercedes-Benz 5.5L biturbo V-8 and the BMW M-series 4.4L TwinPower (twin-turbo) V-8, the new CTS-V is capable of 0-60 performance in 3.7 seconds.

Track-honed design, chassis and suspension elements complement the supercharged powertrain and elevate CTS-V’s capability, performance and driver control to new thresholds, while enabling track driving without modifications or special procedures. Key performance technologies include:

  • Standard carbon fiber hood and available carbon fiber vent, front splitter, rear spoiler and rear diffuser for greater aerodynamic performance
  • Brembo high-performance brake system developed to provide durability, consistency and the capability for track-day performance straight from the factory
  • Third-generation Magnetic Ride Control delivering 40-percent faster damping response
  • Integrated chassis controls that provide balanced performance for touring and the track, including competition-spec Performance Traction Management
  • Structural stiffness increased by 25 percent for improved ride and superior handling
  • Driver-selectable modes electronically calibrate performance variables for touring, sport and track driving conditions
  • Michelin Pilot Super Sport tires with tri-compound technology offering excellent grip with extended wear
  • An interior with performance-oriented, sueded microfiber accents and matte-finish carbon fiber trim and available RECARO high-performance seats for spirited driving
  • Advanced safety and parking technologies, including a front curb-view camera system that provides a visual cue of curbs to protect the front splitter; automatic parking assist to find and steer into parallel or perpendicular parking spots; side blind zone alert, forward collision alert, lane keep assist and rear cross traffic alert.

Additionally, the Performance Data Recorder in the CTS-V allows drivers to record high-definition video, with data overlays, of their driving experiences on and off the track, enabling sharing on social media.

More powerful supercharged V-8 engine
The power behind the new CTS-V’s capability is an all-new, more powerful 6.2L supercharged V-8 engine that makes more power more efficiently than the previous Cadillac supercharged engine. It employs a more-efficient, more-compact 1.7L supercharger and matches it with direct injection and Active Fuel Management (cylinder deactivation).

The supercharger’s rotors are smaller in diameter than the previous supercharged engine, allowing higher maximum rpm that enables power-enhancing boost to be generated earlier in the rpm band. That boost is achieved more efficiently via a more direct discharge port that creates less turbulence, reducing heat and speeding airflow into the engine.

The Cadillac supercharged engine also has several unique features designed to support its high output and the greater cylinder pressures created by forced induction, including Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional aluminum heads, and lightweight titanium intake valves.

The CTS-V’s complementing eight-speed automatic is tuned for world-class shift-response times. Smaller steps between gears keep the engine within the sweet spot of the rpm band, making the most of the output of the supercharged engine for exhilarating performance and greater efficiency.

The new 8L90 transmission offers full manual control via steering wheel paddles, and Performance Algorithm Shifting to deliver shift performance that rivals the dual-clutch/semi-automatic transmissions found in many luxury performance sedans – but with the smoothness and refinement that come with a conventional automatic fitted with a torque converter.

Stronger structure enhances body motion control
The CTS’s structure is highly mass optimized and designed to meet higher performance requirements, with enhancements to the V-Series developed to respond to cornering and torque loads that significantly exceed the levels experienced by the non-V models.

Unique and revised elements include:

  • Strut tower-to-tower brace
  • Strut tower-to-plenum brace
  • V-braces for the engine compartment
  • Strengthened rocker bulkhead
  • Stronger rear cradle-to-rocker braces
  • A unique aluminum shear panel at the front of the chassis
  • Upper tie bar-to-bumper braces.

The enhancements bolster structural stiffness by 25 percent over non-V models, for more precise handling and steering – and a more confident feel from a vehicle that conveys strength through exceptional solidity.

“With the stronger body structure – and more than a decade of V-Series production models and the CTS-V racing program experience – engineers tuned the CTS-V to deliver greater body motion control for a more agile feel, while maintaining excellent ride quality,” said David Leone, Cadillac executive chief engineer. “The result is class-leading capability on the highway or track, balanced with luxury and refinement.”

Track-honed chassis and suspension
The CTS-V shares the same 114.6-inch (2,910 mm) wheelbase as the CTS non-V-Series models, but has wider front and rear footprints that enhance grip, reduce body motion and contribute to more direct-feeling steering.

Nineteen-inch wheels wrapped with specially developed Michelin Pilot Super Sport tires give the CTS-Vits footprint and enable nearly 1g in lateral acceleration. The lightweight, forged aluminum wheels – measuring 9.5 inches wide in the front and 10 inches wide in the rear – are constructed of a low-mass forging that helps reduce un-sprung weight for greater agility and a more direct feel to steering inputs.

The wheels are 45-percent stiffer than previous CTS-V wheels, while the Michelin tires feature a tri-compound tread that delivers excellent grip in performance driving situations, while offering excellent ride quality characteristics and extended tread wear.

Additional contributors to the CTS-V’s responsive, connected and track-capable driving experience include:

  • A revised multi-link double-pivot MacPherson-strut front suspension delivers a quicker response and increased lateral control, incorporating “hydro” bushings, where traditional elastomeric bushings are replaced with zero-compliance cross-axis ball joints, higher-rate springs and a stiffer stabilizer bar – for 20-percent greater roll stiffness
  • The ZF Steering Systems Servotronic II variable-ratio electric power steering gear, with 14-percent greater system stiffness for an improved feeling of precision and greater driver feedback
  • Cadillac’s five-link rear suspension features reduced roll center migration, stronger lateral control and effective anti-squat geometry, complementing the front suspension with greater body motion control. Contributing components include stiffer bushings, new cradle mounts, higher-rate springs and a stiffer stabilizer bar
  • A standard electronic limited-slip differential supports optimal traction and enables maximum corner exit acceleration
  • Larger prop shafts and greater half-shaft asymmetry (stiffer driver’s side shaft) mitigate power hop during acceleration
  • A Brembo brake system provides durability, consistency and the capability for track-day performance. The system includes two-piece 15.3-inch-diameter (390 mm) front rotors with staggered six-piston calipers and 14.3-inch-diamter (365 mm) rear rotors with four-piston calipers.

Also, the CTS-V features third-generation Magnetic Ride Control and Performance Traction Management. Four driver-selectable settings – Tour, Sport, Track and Snow – electronically calibrate performance variables to optimize the car for driving conditions. Performance Traction Management is offered in Track mode and features five settings of torque reduction and brake intervention for track driving.

Magnetic Ride Control “reads” the road a thousand times per second, sending data to magneto-rheological fluid-filled dampers that can independently control the damping characteristics of all four dampers. Third-generation improvements enable 40-percent faster damping response. At 60 mph, the third-generation magnetic ride control system calculates the optimal damping force for every inch of the road.

Functional form
Almost every exterior panel on the CTS-V is unique, from the fascias and fenders, to the hood, rear spoiler and rocker moldings – and each was designed to support the car’s capability, contributing to lift reduction, enhanced cooling or both.

The unique elements include:

  • A lightweight carbon fiber hood featuring an air-extracting vent that pulls hot air out of the engine compartment and helps reduce lift at speed by channeling air pulled through the radiator out and over the top of car rather than allowing trapped air to exit under the car
  • Unique front and rear fascias provide optimal aero performance, with larger grille openings in the front fascia to feed more air to the supercharged engine. Even the mesh pattern of the signature grille openings is enlarged to allow more air into the radiator and multiple heat exchangers
  • A front splitter enhances handling by forcing air to push down on the front of the car rather than flow under it, where it can cause lift
  • Wider fenders to accommodate the wide, 19-inch wheels and Michelin Pilot Super Sport tires
  • The rocker moldings and rear spoiler are aero-optimized
  • The forged aluminum wheels and brake calipers are offered in three finishes, allowing owners to personalize the appearance of the CTS-V.

An available Carbon Fiber package takes aero performance and mass optimization to higher levels. The Carbon Fiber package includes a more aggressive front splitter, hood vent, rear diffuser and spoiler.

V-Series is the emotive core of Cadillac and the apex of the brand’s Art and Science design philosophy,” said Andrew Smith, executive director, Cadillac Global Design. “The CTS-V reflects that with a bold sense of arrival, serious performance, seamless integration of technology and precision in its craftsmanship. The exposed carbon fiber components, for example, are book-matched on the centerline for a more precise, tailored appearance.”

Performance-focused cabin
The CTS-V’s dual-purpose capability carries over to the interior, where the design and relationship of key components are focused expressly on performance-driving ergonomics.

“With the performance the new CTS-V is capable of delivering, the interior needs to be as functional as the other vehicle systems,” said Smith. “All of the contact points – the steering wheel, seats, shifter and pedals – are designed to make performance driving experiences direct and intuitive.”

The CTS-V features standard 20-way performance-oriented heated and ventilated front seats trimmed in semi-aniline leather, with sueded microfiber inserts and seatbacks. Available RECARO performance front seats deliver aggressive, adjustable bolsters that help hold the driver and front passenger in place during high-load cornering. They also have a luxury-performance feel, trimmed in Mulan leather with sueded microfiber inserts and seatbacks.

Additional features include Cadillac’s cut-and-sew elements, with decorative stitching and authentic materials such as available sueded steering wheel and shift knob. Three color combinations are offered: Jet Black, Jet Black with Light Platinum accents and Saffron with Jet Black accents.

The CTS-V features a unique version of the 12.3-inch instrument panel cluster display, with V-Series graphics and distinctive gauge readouts and complementing full-color, reconfigurable head-up display. It is also equipped with the latest connectivity technologies from Cadillac:

  • CUE with Bluetooth connectivity with natural voice recognition
  • Navigation with Bose Surround Sound audio
  • Siri Eyes Free and text-to-voice that converts incoming text messages to speech and reads them over the audio system speakers
  • Wireless inductive phone charging
  • OnStar 4G LTE connectivity with built-in Wi-Fi hotspot.

The Performance Data Recorder is controlled via CUE’s color touch screen, and recordings can be reviewed on the screen when the vehicle is parked.

The Backstory of Cadillac’s New Massage Chairs

article.articleDETROIT – No time today to make it to the spa or schedule a visit with the massage therapist, no problem. On two 2015 models, Cadillac is offering front driver and passenger seats that can knead, roll and relax your back as you drive. An anti-fatigue option is also offered for the driver.

The 22-way adjustable heated and ventilated seats now have a luxury option with a massage seat that works in the upper shoulder area, back lumbar or cushion.

“Many Americans have the common misconception that massage is just a luxurious way to relax. The benefits of massage are actually wide-ranging, especially for those that work that monotonous daily grind behind a desk or the wheel of car,” said Dr. Leena S. Guptha, board chair, National Certification Board for Therapeutic Massage & Bodywork.

While the seat is unable to provide the same experience as a trained practitioner, it can at least offer some comfort for a driver and passenger.

“This feature gives customers another way to improve their drive,” said Elizabeth Hayes, General Motors engineering group manager. “Once a massage setting is stored, a driver simply has to push the button and engage the luxury option. It is our goal to always find ways to make getting from point A to point B a little more pleasant.”

How it works
The massage seats’ settings can be stored in the car’s memory like the seat positions. With a toggle switch or activation button, both on the outboard base of the seats, the driver and front seat passenger can direct the illustration of adjustments on the infotainment screen. The desired massage and intensity can both be controlled from the screen.

Once the optimal massage is found, the driver can save the kneading, rolling or anti-fatigue setting by pressing the memory button on the door. Reactivation can then occur by simply pushing the button on the seat base.

The massage seat is available on the XTS Premium and Platinum Collections and on the Escalade Platinum Collection.

Cadillac Adds Streaming Video to Enhance Driver Vision and Safety

Display eliminates visual obstructions, increases rearward vision by 300 percent

DETROIT – Cadillac late next year will add high-resolution streaming video to the function of a traditional rearview mirror, removing obstructions of passengers, headrests and the vehicle’s roof and rear pillars.

The streaming video mirror improves field of vision by an estimated 300 percent, or roughly four times greater than a standard rearview mirror.

“The closest comparison to this kind of rear vision would be driving a convertible with the top down,” said Travis Hester, Cadillac CT6 executive chief engineer.

“In addition to the increased field of view, the technology eliminates any rear seat, rear pillar or passenger obstructions, allowing the driver an unimpeded view of the lanes behind and traditional blind-spots,” Hester said.

Thanks to a high dynamic range, the camera’s video feed reduces glare and allows a crisper image in low-light situations, versus a traditional glass electrochromatic, or auto-dimming, rearview mirror. The in-mirror display is an industry-leading 1280 by 240-pixel TFT-LCD display with 171 pixels per inch, combined with a HD camera designed specifically to enhance rear view lane width and maximize low-light situations.

A water-shedding hydrophobic coating is applied to the camera to keep it clean to maintain visibility regardless of the driving conditions.

Researchers and engineers working on this Cadillac innovation have been awarded 10 patents – one for the streaming video mirror and nine for video processing. The patents cover innovations in the wide field of view camera image calibration, de-warping, glare reduction and camera hardware design.

Drivers can disable the mirror’s video streaming function; flipping the toggle on the underside of the mirror will revert it to a traditional electrochromatic rearview mirror.

“The streaming video is a significant enhancement for the luxury customer interested in purposeful technology,” Hester said.

The technology will debut on the 2016 Cadillac CT6.

Corvette Engine Repeats Win as WardsAuto 10 Best 6.2L LT1 among industry’s elite powerplants

1418156839916DETROIT – The high performance, technology-packed LT1 Small Block 6.2L V8 that powers the 2015 Corvette Stingray is a Ward’s 10 Best Engine for 2015. The engine also was recognized with this award in 2014.

WardsAuto reviewed 37 engines and propulsion systems from 12 manufacturers in this year’s competition, which looked at power, fuel efficiency, new technology and refinement and compared the attributes with data for similar engines.

“This recognition is another step in earning customers for life,” said Dan Nicholson, vice president, GM Global Powertrain. Having the WardsAuto experts choose the LT1 as one of the best in the industry two years in a row is proof of what this Powertrain team can deliver – uncompromised performance, durability and efficiency that helps make the Stingray one of the best sports cars in the world today.”

The LT1 Small Block technologies contribute to making the new Corvette the quickest, most powerful and most fuel-efficient standard Corvette ever. The engine delivers an SAE-certified 460 horsepower, helping propel the car from 0-60 in 3.8 seconds and a quarter mile in 12 seconds while offering EPA-estimated 29 mpg highway with an 8-speed automatic or 7-speed manual transmission.

“The 6.2L LT1 V-8 is the heart and soul of the seventh-generation Chevrolet Corvette, and it proudly upholds the 60-year legacy of small-block engines from General Motors,” said Tom Murphy, executive editor of WardsAuto World digital magazine. “This one’s been re-engineered from head to torque converter, and the LT1 is the crown jewel of this massive engine family.”

“In the Corvette, this 460-hp V-8 barks with authority, delivering an exhaust note reminiscent of Detroit’s finest muscle cars. And it’s efficient, too. WardsAuto editors flogging the ‘Vette for more than 300 miles managed better than 20 mpg with the new 8-speed automatic.”

The LT1, part of the Gen 5 family of Small Block engines, combines several advanced technologies – direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing – to support an advanced combustion system.

Direct injection is a primary contributor to greater combustion efficiency by ensuring a more complete burn of the fuel in the air-fuel mixture. This is achieved by precisely controlling the mixture motion and fuel injection spray pattern. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio.

Increased power and efficiency result from more than 10 million hours of computational analysis including computational fluid dynamics, to make the most of the combustion system, the direct injection fuel system, active fuel management and variable valve timing systems that support it. The combustion system itself benefited from 6 million hours of dedicated CPU analysis time.

Other variants of the Gen 5 Small Block include the 4.3L V6, 5.3L and 6.2L V8 truck engines offered in the Chevrolet Silverado, Suburban, Tahoe, the GMC Sierra pickups, Yukon XL and Cadillac Escalade SUVs. The LT1 is manufactured in Tonawanda, N.Y.

Founded in 1911 in Detroit, Chevrolet is now one of the world’s largest car brands, doing business in more than 140 countries and selling more than 4.5 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, and high quality.

GM Invests In Next Gen Volt and ‘Two Future Products’

General Motors has said it will not be caught behind in automotive propulsion electrification, and today it again backed that statement with substantial investments for its Chevrolet Volt and “two future products” yet to be revealed.

The company said it will invest $449 million to upgrade processes at its Detroit-Hamtramck Assembly and Brownstown Battery Assembly plants.

This is the largest infusion of cash to these facilities to date, GM said. The breakout is $384 million for new body shop tooling, equipment, and additional plant upgrades at Detroit-Hamtramck, and $65 million for the next generation of lithium-ion battery production and future battery systems at Brownstown.

“General Motors is committed to building award-winning products and developing technologies in America, which helps to grow our economy from a resurgent auto industry,” said Gerald Johnson, GM North America Manufacturing vice president. “These investments will help the next-generation Chevrolet Volt build on its position as the leader in electrified propulsion.”

General Motors points out that Detroit-Hamtramck is “the world’s only automotive plant that mass-produces extended-range electric vehicles.”

Said vehicles are of course, the Volt, Cadillac ELR, and Opel/Vauxhall Amperas. These vehicles, particularly the Volt and its Ampera siblings, are marketed to 33 countries. Also built at Dham are the Chevrolet Malibu and Impala.

The Detroit-Hamtramck facility has on site a 264,000-square-foot photovoltaic solar array that can generate up to 516 kilowatts of electricity which is enough to charge 150 electric vehicles per day.

GM’s Brownstown Battery Assembly plant is a 479,000-square-foot, landfill-free facility south of Detroit that assembles the lithium-ion battery packs for the Volt, Ampera, and ELR. Production there started in October 2010.

The automaker says it is “the first high-volume manufacturing site in the U.S. operated by a major automaker for automotive lithium-ion battery production.”

Funding that made the Brownstown site a reality came through the American Recovery and Reinvestment Act funding through the U.S. Department of Energy.

While GM is focusing on its current Volt, it did utter a few words as to the intent of its investments that speak volumes: “to build the next generation Chevrolet Volt and two future products.”

Speculation – some of it ambiguous and questionable – has been that more models may be announced in due time based on Voltec technology.

The hint was in the air today, as even Detroit’s mayor alluded to future product not yet revealed.

“This is a significant investment by General Motors and it helps to further position Detroit as a leader in the innovative technologies of tomorrow,” said Detroit Mayor Mike Duggan. “We anticipate that the upgrading of the Detroit-Hamtramck Assembly Plant and the production of GM’s next-generation electric vehicles will create well-paying jobs for Detroiters. As we continue to bring real change to our city, we need partners like GM who are committed to investing in our future.”

Preparing For The Decade Ahead

Leaders including Michigan Gov. Rick Snyder were on hand to show support for job creation and economic stimulus being pumped in by GM, but advanced-tech car enthusiasts have been wondering whether GM will be left behind.

US

GM has been seen by some as less than fully committed as it has no full hybrids, only markets its all-electrc Spark for now in Oregon and California, and does not advertise the “niche” Volt much at all outside of California.

The $76,000-plus ELR was also seen by many as a weak response to the Tesla Model S.

While it looks like a tepid vehicle offering to some, that may be a bit harsh. The Volt enjoys an enormous fan base with owners taking it upon themselves to try and help GM’s marketers in getting the word out.

Somehow infighting between alternative vehicle fans has broken out even at this early stage. In part this has stifled or counteracted the enthusiasm and those for whom the Volt is not their cup of tea have spoken strongly against it and its maker.

GM’s official strategy has been to not display its hand, not hype its future, and some have taken this a vote of little or no confidence by GM in electrification.

Compared to companies like Tesla Motors and Nissan, both of which are bullish in their own right on EVs, some have said GM needs to show more enthusiasm.

Even with today’s announcement, “future” cars are not being named other than the already known of Volt. But to count GM out or a “second tier” player as some who’ve been fans but now losing the faith have said, this could be a mistake.

ELR_Model_S85

Obviously it would be more exciting for GM to all-of-a-sudden become gung-ho about future tech and start announcing more vehicles in the works.

GM’s strategy is different, but its engineering capabilities are strong. It has a massive battery lab, and global skunk works projects underway, and it is positioned to do things when it wants to.

Whether top management of the large multinational corporation decides to implement what it is capable of does remain in question.

GM otherwise says it will be there with Tesla when the start up actually has its mass market “Gen 3″ car that itself has been delayed from projections of 2015 to now maybe 2017 or so.

This electrified vehicle market is growing – not exploding, but incrementally growing. So for GM, people can either write it off as we’ve seen some saying they’re inclined to do, or they can wait and see what’s next.

2016 Chevrolet Volt Technical First Look A Closer Look at the Volt’s Radical Redo

2016-Chevy-Volt-1Some 69,000 of what marketing director Steve Majoros describes as “the happiest owners on earth” have already racked up 650 million electric miles on their Chevy Volts, and the 2011 model currently ranks tops in class on J.D. Power’s Dependability index. So we were expecting a steady-as-she-goes evolutionary redesign for the 2016 Volt. But what the development team calls the Gen II Volt will be far more radically redesigned than was the Gen II Prius. The entire drivetrain, power controller, battery, and virtually everything connecting the above has been redesigned, right down to the battery chemistry. The only carryover powertrain part is a little yellow shipping cap used to cover the attachment point for the shift linkage (and it gets thrown away at the factory). These new bits will get bolted into brand new bodywork too, but we won’t see that until January’s Detroit show.

The revisions are aimed at increasing performance and range at reduced cost. Despite the fact that most customers do their level dangdest to never fire the 1.4-liter engine, it has been swapped out for an all-new 1.5-liter I-4 from a new modular EcoTec small-engine architecture, featuring direct injection, 12.5:1 compression, cooled exhaust-gas recirculation, and cam phasing with wide-range authority to permit Atkinson-cycle operation. This more powerful and torquier engine is so much smoother and more refined that it can run at up to 5600 rpm (the old one was capped at 4800 rpm to tame the din). Official figures haven’t been released, but at a previous event for the EcoTec engine family, the 1.5 was listed at 112 hp and 104 lb-ft (up from the old one’s 84 hp and estimated 92 lb-ft). A new variable-displacement oil pump boosts efficiency, and it’s tuned to run on regular gas. Oh, and it will be built in Flint Michigan.

Further packaging improvements and mass reductions are being achieved by integrating the Traction Power Inverter Module and controller electronics onto the housing for the electric motors and transmission. This eliminates the big orange cables that used to connect the body-mounted controller to the transmission. This change, and the nature of ever-shrinking microelectronics, wrought a 60-percent volume reduction in the power electronics and helps the powertrain shed 100 pounds.

But the real kicker is the complete redesign of the guts of this transmission. Instead of having one big honker electric machine providing virtually all of the drive force through a single planetary gearset, there are now two separate motors of slightly different designs with different peak operating ranges. This allows them to work alone or together depending on the driver’s demands in different modes to better optimize efficiency. The smaller one uses a ferrite material in lieu of pricey and scarce rare-earth metals, and the other one uses a rare-earth formula that’s less rich in the rarest heavy metals (this model uses 60 percent less rare-earth metals). Two planetary gearsets now manage the five different operating modes (up from four, as reflected by the transmission’s official nomenclature: 5ET50, replacing 4ET50). There’s 10 percent less steel in the two motors for a 33-pound weight savings.

Low-speed acceleration is said to be improved by 20 percent, while overall drivetrain efficiency increases by 12 percent. So let’s make some wild guesses here. Let’s say the new Volt uses 70 percent of the battery pack that we’re guessing jumps to 20.5 kW-hrs (up from the current Volt’s 60 percent). That would suggest the current Volt’s EPA-estimated EV range of 38 miles might jump to 53. Factor in the 12-percent drivetrain-efficiency boost and you’re at 59 miles. One promise: Some of these assumptions are wrong, and factory claims will likely be conservative, but a 50-mile range will have a nice round marketing ring to it. Stay tuned for more info in January, and a complete explanation of the nitty-gritty planetary details when an SAE paper is published in February.
