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 Sonic shreds like a skateboard

Despite the fact that the 2013 Chevy Sonic is a fun, plucky little thing - especially in ever-so-slightly hotter RS guise - it is not, in fact, a skateboard. But don't tell that to rapper Theophilus London.
In General Motors' latest spot for the Chevrolet compact, London needs to make a quick run to the store for some milk. And even though, once again, the Sonic is not a skateboard, it ollies, pops and gets air because, you know, it's just so much fun to throw around.
If this video looks familiar to you, it's because this is the full ad that we first got a preview of in Chevy's longer, full-line spot, where the brand's "Find New Roads" tagline was introduced. Scroll down to see this dedicated Sonic spot, along with the older ad, and remember, the Sonic is still - still - not a skateboard.

2021 Jeep Grand Cherokee L vs Big Three-Row Crossovers | Spec comparison

The three-row 2021 Jeep Grand Cherokee L is here, entering an ever-growing segment of big crossovers that Jeep has ignored since the Commander of the late 2000s. Of course, the Dodge Durango has basically been a three-row version of the current Grand Cherokee with Dodge styling and a different interior, so it's not like The Corporate Entity Formerly Known as Chrysler has been without a contender in the segment. Jeep is a stronger brand than Dodge, however, and the three-row midsize segment is stronger than those with two rows (there's a vast sales difference between the Chevrolet Traverse and Blazer, as well as the Honda Pilot and Passport). In other words, the Grand Cherokee L could be a very big deal. It is also, quite literally, a very big deal. As you're about to see, it is now the largest three-row crossover, besting the length, wheelbase and height of even the gargantuan Traverse. There's more to the story than that, however, so we put together the below comparison chart to show you how the new Grand Cherokee L lines up on paper versus the biggest three-row crossovers. That includes the 2021 Ford Explorer, 2021 Kia Telluride, 2021 Hyundai Palisade and 2022 Chevrolet Traverse. This group also represents some of the strongest entries in the segment as well as those we feel are most likely to be considered alongside the big Jeep. To that end, we also included the 2021 Lincoln Aviator in the chart since its base price is actually less than what we anticipate the luxurious, range-topping Grand Cherokee L Overland and Summit trim levels to start.  Engines and drivetrains Note the differences in curb weight here. The Grand Cherokee L has the highest base curb weight of the group apart from the high-lux Aviator, yet its 3.6-liter V6 has the least amount of power and torque. Therefore, it'll be surprising if it's not the slowest in the group. There's of course the Hemi V8 available on the top Overland and Summit trim levels, but again, a hefty curb weight works against it. At 5,330 pounds, the lightest V8-powered JGCL weighs 600 pounds more than V6-power Explorer Platinum and ST models. On the other hand, nothing can touch the Hemi Jeep's towing capacity, and only the 400-hp Aviator betters the Jeep's base V6. Its 6,200-pound towing capacity greatly outdoes the 5,000-pound limits of not only the Telluride, Palisade and Traverse, but most others in the segment as well.
