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.

Nissan Leaf makes it 19 in a row for record sales; Chevy Volt drops 21 percent

The Nissan Leaf continues its streak of "best month ever" sales with 2,881 EVs sold in September. Compared to the 1,953 sold in September 2013, that represents an increase of 47.5 percent and, as Nissan itself must be tired of saying by now, it marks yet another best month ever, same as last month and now the 19th in a row. Okay, sure, we know, Nissan will tout this run for as long as it can, but we're certainly expecting it each month, so if it ever doesn't happen, it'll be interesting to see how Nissan talks about it. Year-to-date, Leaf sales are up 35.7 percent compared to 2013. In any case, Nissan's director of EV marketing, Toby Perry, sent AutoblogGreen a statement that said, "Nissan Leaf owners have turned into some of our best marketers, and they jump at any opportunity to share their enthusiasm with friends and family. Take National Drive Electric Week – a grassroots celebration of all things EV and the perfect platform for LEAF owners to showcase the benefits of going electric. After celebrating with EV owners in more than 130 cities across the country, we saw a significant increase in Leaf showroom visits with midweek traffic just as heavy as what we see on the weekends." Year-to-date, Leaf sales are up 35.7 percent compared to 2013. Over on the Chevy Volt front, things aren't quite as rosy. After coming off a good August (the best sales month of 2014 by almost 500 units), Volt sales were down to 1,394, a decrease of 21.1 percent compared to September 2013. So far this year, Volt sales are down 13.2 percent year-over-year. It's kind of a stretch, but perhaps people are already waiting for the next-gen Volt, which will be revealed at the Detroit Auto Show in January, to go on sale? Speaking of things we say every month, our in-depth round-up of US green car sales is in process and will be appearing soon. Until then, please discuss how these two long-standing plug-in champs are doing on the sales floor. Green Chevrolet Nissan Electric Hybrid PHEV ev sales hybrid sales

Chevy Silverado Midnight Edition, Custom ready to stand out in pickup line

Chevrolet spent its Chicago Auto Show introducing a pair of fullsize pickups that promise image-conscious buyers a truck experience that goes beyond the standard range, with the murdered-out Midnight Edition and the um, not murdered-out, Custom. Let's start with the Custom, which adds 20-inch alloys, as well as chrome bumpers, mirror caps and door handles to the Silverado LS. Available in both V6 and V8 varieties, and with the customer's choice of two- or four-wheel drive, the Silverado Custom is the decidedly mellower example of Chevy's special edition styling. The Midnight Edition, meanwhile, throws subtlety out the window with a menacing set of visual upgrades. Based on the Z71, the Midnight adds 18-inch wheels, a spray-in bedliner and unique Z71 and Bowtie badges, all in black, of course. The front and rear bumpers, headlamp bezels, tow hooks, mirror caps and door handles, are also finished in the stealthy shade. Check out our live images of both special edition trucks, and let us know what you think down in Comments.
