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.

Why the Corvette's Performance Data Recorder can be illegal in some states

The Performance Data Recorder with Valet Mode available on the 2015 Chevrolet Corvette Stingray seems like a fantastic tool for many owners. Whether they are taking 720p video while lapping the track in their new 'Vette, or just want to protect their purchase from inconsiderate joyriders, the system offers a lot of functionality in one package. However, one of the PDR's features might get buyers in trouble with the law, and it has nothing to do with recording some illicit high-speed driving on a favorite back road. The problem hinges on the various state laws concerning a person's right to privacy.
According to a letter posted by Jalopnik, Chevy dealers are asking 2015 Corvette owners not to use the Valet Mode portion of the PDR because it records audio in the cabin, in addition to performance specs. That's a problem because privacy laws vary from state to state with some requiring just one side's consent to tape sound and others requiring all parties to agree. According Jalopnik, 15 states mandate everyone's permission beforehand, but it's not clear whether these numbers are up to date. (Actually, the report varies, saying 13 states in some places and 15 in a list.)
According to the letter, Chevy is already working on a software update for the near future to rectify the issue. It's possible that simply adding a warning to drivers and the ability to turn off the audio recording function in Valet Mode might solve the problem. Obviously, this doesn't preclude Corvette drivers from using the performance aspect of the PDR, and owners are free tape lap after lap at the track.
