2016 Chevy Volt powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.

GM plans new car family for global markets, $5B investment

Globalization remains all the rage in the auto industry, as manufacturers scramble to develop single vehicles that can easily be adapted to the world's disparate market places. Ford has been a champion of this movement, with its One Ford mandate, but now, its cross-town rival is getting in on the action, albeit on a smaller scale. General Motors has announced a $5-billion investment to develop a new Chevrolet-badged family vehicle for global growth markets, including Brazil, Mexico, India, and importantly, China. With the PRC listed as a target market for the new vehicle, it's no surprise that GM is teaming with its Chinese joint-venture partner, SAIC Motor, to develop the vehicle's architecture and engines. The first vehicles should be hitting dealers by 2019, with GM expecting to eventually move some two million units per year. "With a significant majority of anticipated automotive industry growth in 2015 to 2030 outside of mature markets, Chevrolet is taking steps to capitalize on that growth," GM President Dan Ammann said in the attached statement. "Strengthening Chevrolet's position through this major investment is consistent with our global strategy to ensure long-term profitable growth in the markets where we operate." GM is quite focused on developing markets for a new vehicle, going as far as to say that "mature markets" like the US aren't currently being considered for the new family vehicle. As for where it will be built, the press release specifically says it won't be exported to the US, meaning it will very likely be built abroad using parts from local suppliers. Read on for the official press release from General Motors. Chevrolet Strengthens Position in Growth Markets with $5 Billion Investment 2015-07-28 All-new vehicle family tailored to local customer requirements General Motors and SAIC Motor partnership further enhanced DETROIT – Chevrolet announced today it is investing $5 billion to strengthen its business in global growth markets through the development of an all-new vehicle family that will meet the rapidly changing demands of customers in these markets. "With a significant majority of anticipated automotive industry growth in 2015 to 2030 outside of mature markets, Chevrolet is taking steps to capitalize on that growth," said General Motors President Dan Ammann.

Chevrolet Colorado ZR2 concept suggests a diesel off-road future

"It takes the Colorado to a whole new place." – Mark Reuss The Chevrolet Colorado looks set to gain a more capable off-road version, with the company previewing a potential design direction with a ruggedized concept Wednesday at the Los Angeles Auto Show. Called the Colorado ZR2, the concept brings back the name used on off-road-tuned S-10 and Blazer models in the 1990s and 2000s. The ZR2 has a track that's four inches wider than the Colorado Z71, which is currently the line's most capable off-roader. The ZR2 is fitted with a new grille, power-dome hood, custom wheel flares and off-road-style fascia that reduces overhang and has flip-out aluminum tow hooks. It's all slathered in an outdoorsy hue dubbed Cyprus Green. The are electronic locking front and rear differentials, skid plates and mono-tube coilover shock absorbers. It all rolls (or crawls) on 275/65R18 off-road tires wrapped around custom 18-inch aluminum wheels. There's also a spare tire assembly mounted in the bed, which has a spray-in liner and 48-inch lift jack should things go afoul on the trail. "It takes the Colorado to a whole new place," Mark Reuss, General Motors executive vice president of global product development, said at the reveal. Power comes from the 2.8-liter Duramax diesel engine making 181 horsepower and 369 pound-feet of torque. This engine will arrive later in the year in the production Colorado. While the ZR2 remains only a concept, it suggests a new path for the Colorado – one we hope Chevy decides to take. Chevrolet Introduces Colorado ZR2 Concept Aggressively styled, more capable and driven by new 2.8L Duramax diesel engine LOS ANGELES – Chevrolet today introduced the Colorado ZR2 concept – a vision of how Chevrolet could take the all-new midsize truck's off-road capability to the next level. It also showcases the new 2.8L Duramax diesel engine that will arrive in the Colorado lineup later next year. The aggressively styled concept builds on the capabilities of the production Colorado Z71 and advances the legacy of Chevrolet's previous ZR2 production models. "From the bold stance to the trail-ready special equipment, the Colorado ZR2 is all about the fun of driving where the pavement ends – and doing it in characteristic Chevy style," said Tony Johnson, Colorado marketing manager.
