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.

Jeff Gordon to pace Indy 500 in Corvette Z06

The Chevrolet Corvette has served as pace car for the Indianapolis 500 more than any other vehicle in the century-long history of the race. And this year it'll be at the front of the pack again in the form of the Corvette Z06 driven by Jeff Gordon. With 650 horsepower on tap, the Z06 is among the fastest, most powerful cars ever to serve as pace car for the Greatest Spectacle in Racing – right up there, at any rate, with the ZR1 that led the field in 2012 and the Viper GTS from 1996. For this year's race, it's been decked out in white with special graphics, strobe lights and a red interior. The 99th running of the race will mark the 13th time a Corvette has been tapped for the honor. Gordon, a name better known to NASCAR fans, but certainly no stranger to the track, will handle driving duties. The four-time Sprint Cup champion has won the Brickyard 400 no less than five times, including the very first time it was held back in '94. No driver has won at Indy more than Gordon – a record he shares with Michael Schumacher, who won the US Grand Prix there five times. (AJ Foyt, Al Unser and Rick Mears share the record for Indy 500 victories at four apiece, in case you were wondering.) It'll be a busy Sunday for Gordon, who will also be competing in the Coca-Cola 600 at Charlotte on the same day. Jeff Gordon to Drive Corvette Z06 Indy 500 Pace Car Five-time Brickyard winner will lead pack for 99th running of the Indianapolis 500 2015-04-29 INDIANAPOLIS – Five-time Brickyard 400 winner and four-time NASCAR Sprint Cup champion Jeff Gordon will drive a Corvette Z06 pace car for the 99th running of the Indianapolis 500 mile race, May 24 at the Indianapolis Motor Speedway. It is the 13th time a Corvette has served as the official pace car, dating to 1978, and the 26th time a Chevrolet has led the pack for "The Greatest Spectacle in Racing." Corvette has served as the pace car more than any other vehicle in the race's history. Gordon, who grew up in nearby Pittsboro, Ind., is no stranger to the Indianapolis Motor Speedway. In 1994 he won the inaugural Brickyard 400 – the first-ever NASCAR race at the Brickyard, and has visited the winner's circle there four more times. That makes him one of only two five-time winners at Indy in any series. Michael Schumacher won five Formula One races there. "It's great to have Jeff Gordon serve as this year's pace car driver," said Jim Campbell, Chevrolet U.S. vice president of performance vehicles and motorsports.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.
