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.

Recharge Wrap-up: meet the Luka EV project, VisibleTesla allows Model S hacking

Select Registry is partnering with Tesla to install chargers at many of its lodgings. More than 170 hotels, inns and bed & breakfasts will install Tesla High Power Wall Connectors for their guests to use. So far, 63 properties have installed the chargers. Eventually, Select Registry members in 34 states as well as Nova Scotia will offer charging on-site. Tesla's wall charger provides the Model S with 58 miles of range per hour. The hotels will rent you a room for the full night, as well. Read more in the press release below. Tesla Model S owners can hack their car with the VisibleTesla app. The free, open source app allows users to check on and control the status of the car and its subsystems, similar to Tesla's official apps. VisibleTesla can also be used to schedule certain automated commands. For example, its creator, Joe Pasqua, has his car send him a text message reminding him to bring his bags with him when he enters the grocery store parking lot. Other users have the car remind them if the car is not charging at a certain time, or schedule the car to turn on the heat before departure.

Employees, particularly the utility's energy efficiency experts, will use the cars to travel to customers' homes and businesses to conduct energy audits. "We are leading by example and demonstrating to our customers, and other Georgia businesses, that electric transportation works for all drivers," says Georgia Power Chairman, President & CEO Paul Bowers. Georgia Power also offers charger rebates and special rates for EV customers. Read more at Domestic Fuel. The Luka EV is a project to build an affordable, lightweight, retro-looking, road-legal electric car in one year. The team wants to get the car certified for use on EU roads by September 2015. They have goals of achieving a driving range of 300 kilometers (about 186 miles), keeping the cost under ˆ20,000 (about $22,280 US at current rates) and the weight under 750 kilograms (about 1,650 pounds). The builders recently completed their first range test of the working vehicle, which uses in-hub motors for propulsion. Learn more at the Luka EV project page on Hackaday.

UAW to vote on strike at Kentucky Corvette plant

The current wait time for a new Chevrolet Corvette Stingray is well, not short. With word of a strike at the Bowling Green, KY factory responsible for seventh-generation sports car, though, that wait time could end up growing substantially.
Now, a strike is still a ways off. UAW Local 2164, which represents the 800 workers responsible for screwing the Corvette together, is set to vote on authorizing a strike today, but even if the employees give the action a go, it's far from a sure thing. According to The Tennessean, both regional and national union officials would need to put their stamp of approval on strike action.
"The membership has to vote to strike, but it's just a step in the process," said Gary Casteel, the UAW's Region 8 director and one of the people that would need to authorize a strike action. Casteel told The Tennessean, "It's purely a local situation, though. They are having some issues with the local management."
