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.

Both Android Auto and Apple CarPlay slated for Chevrolet lineup

Long awaited, the race among automakers to keep drivers connected to their smartphones has officially entered a new era. Hyundai said Tuesday it would be the first manufacturer to put Google's Android Auto into a production car, the 2015 Hyundai Sonata sedan. Not to be outdone, General Motors said today it'd offer both Android Auto and Apple's CarPlay on several Chevrolet models set to hit dealerships this summer. By giving car buyers the choice between these rival phone-projection systems, Chevrolet hopes to quell concerns from prospective customers worried about the compatibility of their smartphones and vehicles. "It's about providing choice," said Alicia Boler-Davis, GM's senior vice president for global connected car consumer experience. "No two customers are alike, and we cannot expect a single solution that works for every driver in every situation." Across the industry, automakers are rushing to add both to their cars as a growing base of customers seek an array of connected features. Estimates from automotive technology research firm SBD indicate smartphone-integrated content is available in 36 percent of current vehicles, and the company expects that penetration rate will grow to 84 percent by 2025. For Chevrolet, the systems will be available on select 2016 iterations of the Cruze, Camaro, Volt, Spark and Malibu as early as next month, and appear on 14 Chevy models overall for the 2016 model year. They're available on all trim levels, but they only work with the company's MyLink infotainment package installed in the cars, and the first to hit showrooms will only work on the seven-inch touchscreen models. "CarPlay and Android Auto, these are things that are addressable to the broad market, and I think it makes a lot of sense for GM to put it into Chevys first," IHS Automotive senior analyst Mark Boyadjis said. Via physical connections, both Apple CarPlay and Android Auto allow users access to smartphone features like turn-by-turn directions, phone calls, voice-to-text messages and music streaming. Interfaces are similar to the ones found on the respective smartphones, but on the dashboard, they're redesigned for a simpler, in-car experience. Fonts are larger, for example, and easier to press on a touchscreen. CarPlay relies heavily on Siri so that drivers spend more time staring at the road instead of their touchscreen. That sounds good, at least in theory.

Recharge Wrap-up: Renault Zoe recall, Proterra buses log 2M miles

Renault is recalling 10,649 examples of its Zoe electric car for potential brake hose failure. Cars built at the company's Flins factory between the Zoe's 2012 introduction and October 6, 2014 - a quarter of all Zoes ever built - are subject to the recall, though no accidents have been reported from rupturing brake lines. Recalled vehicles will have the brake hose positions inspected and, if need be, fixed. Read more from Reuters. Proposed legislation in Massachusetts would make the state even more EV friendly. While the state already encourages EV adoption with a $2,500 rebate incentive, the new bill would give battery electric vehicle drivers HOV lane access. Additionally it would set up a standard building code for EV chargers, and allow EV-only parking spaces. "With decreased gas prices, a 10 percent increase in vehicle miles traveled over the last 20 years, and a carpool rate below the national average, we must address personal vehicle use directly as part of our transportation emissions reduction strategy," says Rep. Frank Smizik. Read more from Teslarati. The New York Daily News has named the 2016 Chevrolet Volt as its "Green Machine of the Year." Seamless operation, peppiness, and a nice suite of equipment make it a top choice for the publication. "The 2016 Chevrolet Volt is all new, inside and out, and takes the plug-in hybrid segment to another level, thanks to its increased EV range, updated cabin, and more efficient gas-powered engine," writes Daily News Autos writer (and all-around good guy) Nick Kurczewski. Honorable mentions go to the Tesla Model S, BMW i3, Toyota Prius, and the hydrogen-powered Toyota Mirai. Read more from the Daily News, or at Clean Technica. Proterra electric buses have accumulated 2 million miles of revenue service. That equals 3,800 tons of carbon emissions that have been prevented and 420,000 gallons of fuel unburned. Proterra says it has 63 buses in service in 15 cities, and that it is ramping up production to meet growing demand. "This latest milestone exemplifies the economic, environmental and civic value of electric mass transit," says Proterra CEO Ryan Popple, "and demonstrates to the transit agencies that diesel - often viewed as a necessary evil - is no longer necessary."
