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.

2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.

Chevy donates first 2015 COPO Camaro for wounded vets

Want to get your hands on a new COPO Camaro? Only 69 will be made this year before it's phased out ahead of the next Camaro's arrival. And the very first one will be auctioned off this weekend in Palm Beach. That's where Barrett-Jackson will be selling the hand-built drag-racer with the serial number 2015COPO001. The vehicle is being donated by Chevy, with 100 percent of the proceeds benefiting the Achilles Freedom Team of Wounded Veterans, a charitable organization that helps disabled athletes, especially veterans of the armed services. Introduced last fall at SEMA, the 2015 COPO Camaro is built specifically for drag racing with a 350-cubic-inch LSX racing engine with a 2.9-liter Whipple supercharger. It's got 555 horsepower, a three-speed automatic transmission (it's a drag machine, not a circuit racer after all), all the requisite safety equipment, special suspension setup, unique livery and a quarter-mile time in the mid-eights. Look for this unique example to cross the auction block at around 5 PM on Friday, April 18, when we hope it will raise a princely sum for a good cause. 2015 COPO Camaro No. 1 Sale to Benefit Disabled Veterans Top bid from Barrett-Jackson goes to Achilles Freedom Team of Wounded Veterans DETROIT – Chevrolet is selling the first 2015 COPO Camaro race car to raise money for Achilles Freedom Team of Wounded Veterans, which helps wounded veterans participate in marathons and share their success within a supportive community including their families. The hand-built car carries serial number 2015COPO001. It will be sold on Saturday, April 18, at the Barrett-Jackson Palm Beach auction, with 100 percent of the winning bid going to Achilles Freedom Team of Wounded Veterans, a non-profit organization that helps disabled athletes, including veterans, gain access to races, equipment, and training dedicated to improve their physical abilities. "This sale gives the highest bidder the opportunity to buy the first of only 69 factory-assembled 2015 COPO Camaro race cars, the final year of the fifth-generation Camaro," said Jim Campbell, U.S. vice president of Performance Vehicles and Motorsports. "Chevrolet is excited to offer this milestone Camaro to help a very worthy organization." Chevrolet introduced 2015 COPO Camaro No. 001 last fall at the SEMA Show in Las Vegas, and it has been featured in Chevrolet Performance advertising and other marketing initiatives.
