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: BYD unveils 60-ft electric bus, Honda sticking with hybrids in Europe

BYD has debuted a 60-foot electric bus at the American Public Transportation Association Expo in Houston, TX. The Lancaster bus, as it is called, has a 120-passenger capacity and can drive over 170 miles on a single charge. The articulated bus features low floors and no steps, thanks to in-wheel hub motors. BYD also displayed a 40-foot electric bus that drove the 1,500 miles to the show under its own power (recharging along the way, of course). Read more in the press release below. Honda says it will continue to sell hybrids in Europe, despite the fact that it has stopped selling the CR-Z and Insight due to slow sales. "Our focus at the moment is on our 1.6-liter diesel but we haven't forgotten about hybrid technology," says Honda Europe's Philip Ross. Honda will sell the next-generation Fit (badged as the Jazz) in Europe when it launches next summer, and will sell the next-gen hybrid version beginning in 2016. Honda sold 4,500 of the Jazz hybrid in Europe last year. Read more at Automotive News. XL Hybrids is selling its XL3 Hybrid Electric Drive System in California. The news comes after the California Air Resources Board issued an executive order allowing the aftermarket hybrid conversion for 2012-2014 Chevrolet Express and GMC Savana vans. The XL3 Hybrid regenerative braking conversion increases real-world mpg by about 25 percent. Read more in the press release below. NRG eVgo has finished installing 60 charging stations at the Sony Pictures Entertainment studio lot and offices in Culver City, California. The Level 2 chargers, which will be managed by NRG eVgo, allow employees to charge their EVs during the workday. An average of 90 EVs and PHEVs park at the studio headquarters every day, thanks in part to Sony Pictures' Alternative Vehicles Incentive program for its employees. Learn more in the press release below. Pennsylvania's Public Utility Commission will allow operators of EV charging stations to set prices based on kilowatt hour usage. This change ensures that drivers pay for the actual energy they use, rather than the time they spend charging, since different cars can charge at different speeds. Car Charging Group has already begun using the per-kWh fee structure at its charging stations throughout the state. Other states that allow kWh pricing are California, Colorado, Florida, Hawaii, Illinois, Maryland, Minnesota, New York, Oregon, Virginia and Washington. Read more in the press release below.

GM recalls 200k Hummer H3s for fire risk

An issue with fires erupting in some Hummers has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for nearly 200,000 vehicles around the world. The bulk of them are in the United States. According to the first statement (below) obtained by Autoblog from GM, the issue stems from the HVAC system in Hummer H3 models. The connector module for the blower motor has, in certain cases, overheated, melted the surrounding plastic, and started a fire. 42 such cases have been reported, including three instances of occupants citing minor burns. GM confirms that two of those three cases lead to the vehicle being destroyed in the fire, but states that no crashes or fatalities have resulted. The issue affects 196,379 examples of the 2006-10 H3 wagon and the 2009-10 H3T pickup, with 164,993 estimated to be in the United States. In order to fix the issue, dealers are being instructed to replace the relevant parts of the connector and harness. In a second, unrelated campaign, GM is also calling in 50,731 Chevy Spark and Sonic small cars – 45,785 of them in the US – due to a software glitch. In those affected vehicles fitted with the base radio and OnStar system, the audio system may not be able to switch out of turn-by-turn direction mode, causing the display to go blank and all sound to mute – including key safety warnings. In addition, the system may not switch off, draining the battery. GM states that no crashes, injuries, or fatalities have resulted from this issue, and all that dealers will need to do in this case is reflash the software.

The heat could melt the plastic surrounding the connector module, increasing the risk of a fire. Dealers will replace the affected portion of the connector and harness. GM is aware of three reported minor burns and 42 fires but no crashes or fatalities related to this condition. Including Canada, Mexico and exports, the total recall population is 196,379. ### General Motors is recalling 45,785 2014-2015 model year Chevrolet Sparks, and 2015 model year Chevrolet Sonics in the U.S.
