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.

Chevy gives Camaro Red, Black Accents for SEMA

Just the other day, Chevy announced a series of modified show cars it's planning to bring to SEMA this year. Now it has revealed full details on what could prove the most enticing among them in the form of a pair of Camaros. These new Red Accent and Black Accent editions are based on the new, sixth-generation 2016 Camaro SS. The former starts out as a Camaro SS convertible, done up in silver with red trim inside and out. It's got a leather interior, custom grille, hash-mark fender graphics, blacked-out bowtie badge, and 20-inch alloys. Even the engine is visually enhanced with a red cover. While it was at it, Chevy also dropped the suspension and fitted a new air intake and Brembo front brakes. Joining it is the Black Accent concept, based on a red Camaro SS coupe. As its name suggests, it's got a blacked-out aero kit, bowtie badge, and fuel cover, along with darkened tailllamps and satin black stripes. It also gets a black leather interior and its own set of 20-inch wheels, along with the aforementioned lowering kit, Brembo front brakes, air intake, and red engine cover. The Accent concepts are designed to showcase the extent of the accessories Chevy is offering for the new Camaro, and will be showcased at SEMA alongside modified versions of the Spark, Trax, Malibu, Colorado, and Sierra. Feel free to scope out the gallery above and the details in the press release below.

Camo'd Chevy Camaro ZL1 is one bad boy

Thanks to a fresh gallery of spy shots, we're getting a much better look at the next Chevrolet Camaro ZL1 during its development, and this machine is looking seriously mean. Unlike the last photos, the heavy cladding is gone from the body this time and is replaced by a camouflage wrap. That switch makes checking out the details a whole lot easier. The first thing you'll notice at the front is the massive grille that looks ready to devour anything that gets in the way. To add a little more menace, the lower air dam appears to jut out a bit more, as well. While harder to see in these latest shots, our spies say the hood still boasts an extractor similar to what's found on the Cadillac CTS-V. The big, double spoke wheels look great in black and really dominate the styling in profile. Look past them, and you notice some tweaked side sills, as well. At the very back, you can also spot some styling adjustments to the rear bumper. There's an unmissable wing back there, too. The powerplant for the ZL1 is still a mystery, but it's rumored to use the LT4 6.2-liter supercharged V8. The similar hood design as the CTS-V is one piece of evidence to support that. Even with the same engine, Chevy's engineers could tweak the output higher or lower than the Caddy. The wait to find out isn't too long because the ZL1 is anticipated to launch for the 2017 model year. Related Video:
