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.

GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

Chevy Malibu rolls over 10 million on the odo

On the cusp on the introduction of the latest model, the Chevrolet Malibu is celebrating a major milestone with 10 million of them now on the road since the car's introduction 51 years ago. While not quite enough to rank among the best-selling vehicles of all time, the feat is impressive considering the name took over a decade off from the Chevy lineup in the '80s and '90s. The Malibu started life in 1964 as the top trim on Chevy's new, midsize model, which also included the 300 and Chevelle. Offered in a plethora of body styles, including a wagon and convertible, the Bowtie brand moved over 370,000 of them in the first year. By 1969, sales reached more than 503,000. However, the market for rear-wheel drive sedans eventually softened in the US, and the Malibu name was dropped in 1983. The moniker returned in front-wheel-drive form in 1997 and has been a part of the lineup again ever since. These days, the Malibu is obviously only available as a four-door, but the model is more efficient than ever. The larger, lighter 2016 example can get up to 37 miles per gallon highway with its 1.5-liter turbocharged four-cylinder or 47 mpg combined when the hybrid goes on sale next year. You can get a great look at the Malibu's changes from the original until now in the gallery above.

Chevrolet celebrated the sales achievement today for the global sedan in the United States, China and Korea, which collectively account for more than 90 percent of sales. The Malibu is sold in more than 25 markets around the world. "The Chevy Malibu joins an exclusive club of vehicles that have achieved this extraordinary milestone and we acknowledge it today by honoring the common thread linking every one produced: The customer," said Alan Batey, president, global Chevrolet. "Some people are buying their very first Malibu today and others may have driven a Malibu from a different generation as their first car. It is a car that has resonated with customers for more than half a century." Chevrolet's interaction with customers has evolved since the Malibu was introduced in 1964. Back then, an owner's manual and a personal relationship with the dealer defined conventional customer service.
