2016 Chevy Volt will not need premium gas

Buried in the new technical details of the 2016 Chevy Volt released yesterday was a throwaway line about a small but important change that's due to the new 1.5-liter, four-cylinder engine. The first-gen Volt has always required premium gas but the new powerplant will be happy burning plain old regular. The Volt's chief engineer, Andrew Farah, told AutoblogGreen that the change was due to today's Volt owners explaining they were not happy paying for top-shelf petroleum. "The ability to use regular unleaded was based directly on customer feedback," he said. "Since the range extender is an all-new engine, it was optimized to use regular unleaded at the outset. Using regular fuel will not have effect on vehicle acceleration or other performance factors." As Larry Nitz, GM's executive director of vehicle electrification, told AutoblogGreen yesterday, the new engine is more powerful and quieter than the outgoing 1.4-liter engine that's used in the current Volt. Fuel economy and EV range specs for the next-gen Volt are not expected until the full car is revealed at the Detroit Auto Show in January.

Stop-start standard in four-cylinder 2015 Chevrolet Impala

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined. The 3.6-liter V-6 Impala will not feature stop-start. The 2015 Impala comes equipped with Chevrolet's 2.5-liter Ecotec four-cylinder engine, which will also offer 22 mpg in the city, and 31 on the highway. The 3.6-liter V-6 Impala will not feature stop-start and the mild-hybrid eAssist model from the 2014 MY, which got 29/25/35 combined/city/highway mpg, has been discontinued. Chevrolet spokesman Chad Lyons told Green Car Reports that not even one percent of the 2014 Impalas purchased were the Eco model. So Chevy is trying something different. With a seamless driving experience in mind, the new Impala's stop-start tech features software that governs under what conditions the feature will activate. The engine won't shut off if the car has not reached a speed of six miles per hour, so the start-stop won't be cycling during traffic jams. It can also fire the starter even if the engine has not come to a full stop, which quickens reaction time, particularly in instances of what Chevrolet calls "change-of-mind events." The stop-start function uses information about cabin temperature and humidity as well as battery charge to help determine whether or not to shut off the engine. The 2015 Impala has been engineered to reduce NVH, which will also help create a smoother stop-start experience for occupants, Chevy says. Motor mounts have been updated, and a burlier starter motor will help restart the engine after a stop. The Impala follows the 2014 Malibu as Chevrolet's second vehicle to feature stop-start tech. The four-cylinder model currently makes up over 30 percent of Impala sales. The 2015 Impala will be available beginning this summer, with a base MSRP of $27,735 (including destination charges). And while one MPG isn't a huge difference, neither is the price increase of just $50 for a bit of eco-minded innovation. Read on for more details in the press release below. Chevrolet Makes Stop/Start Standard in 2015 Impala Technology improves city fuel economy by 5 percent 2014-05-22 DETROIT – Stop/start technology will be standard on the 2015 Impala base 2.5-liter ECOTEC® engine, an addition that improves the vehicle's city fuel economy by nearly 5 percent, or one mile per gallon.

GM isn't liable for punitive damages in ignition switch cases

NEW YORK — A federal appeals court said General Motors is not liable for punitive damages over accidents that occurred after its 2009 bankruptcy and involved vehicles it produced earlier, including vehicles with faulty ignition switches. The 2nd U.S. Circuit Court of Appeals in Manhattan said on Tuesday that the automaker did not agree to contractually assume liability for punitive damages as part of its federally-backed Chapter 11 reorganization. GM filed for bankruptcy in June 2009, and its best assets were transferred to a new Detroit-based company with the same name. The other assets and many liabilities stayed with "Old GM," which is also known as Motors Liquidation Co. Tuesday's 3-0 decision may help GM reduce its ultimate exposure in nationwide litigation over defective ignition switches in several Chevrolet, Pontiac and Saturn models. It is also a defeat for drivers involved in post-bankruptcy accidents, including those who collided with older GM vehicles driven by others, as well as their law firms. The ignition switch defect could cause engine stalls and keep airbags from deploying, and has been linked to 124 deaths. A lawyer for the drivers and their law firms did not immediately respond to requests for comment. GM had no comment. Circuit Judge Dennis Jacobs said GM's agreement to acquire assets "free and clear" of most liabilities excused it from punitive damages claims for Old GM's conduct. He also noted that the judge who oversaw the bankruptcy concluded that the new company could not be liable for claims that the "deeply insolvent" Old GM would never have paid. The decision upheld a May 2018 ruling by U.S. District Judge Jesse Furman in Manhattan, who oversees the ignition switch litigation. Drivers have sought a variety of damages in that litigation, including for declining resale values. GM has recalled more than 2.6 million vehicles since 2014 over ignition switch problems. It has also paid more than $2.6 billion in related penalties and settlements, including $900 million to settle a U.S. Department of Justice criminal case.
