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 will make Chevy Volt production announcement tomorrow

Thing are apparently happening to get the next-generation Chevy Volt ready for public consumption. The most obvious proof is in a preview of an announcement (possibly coming tomorrow) that the two main places where General Motors gets the Volt ready -the Detroit-Hamtramck Assembly Plant and the Brownstown Township battery assembly facility - will be getting big money upgrades and lots of new positions. The Hamtramck plant builds the Volt and its fancier cousin, the Cadillac ELR, as well as the global versions of the Volt. The Detroit News reports that GM will add 1,400 jobs and spend roughly $450 million at the two locations in order to build the redesigned Volt. What's less clear is exactly what the updates will bring us. We've heard that the new volt will be a 2016 model and come on a new chassis. Speculation in The Detroit News about tomorrow's announcement runs the gamut from a new compact PHEV with less electric range and a lower price (which makes sense) to an updated Volt with more electric range (heard it before) to a new all-electric vehicle (the moon shot). If there's any hints to be gleaned in the international Volts, there are also reports coming in that the Opel brand will get an all-electric vehicle that is cheaper than the Ampera. Read into that what you will. We pestered GM's Kevin Kelly on the new Volt (again) and he said (again) that he couldn't give out any more detail other than what's been reported. He just told AutoblogGreen that there will be an announcement tomorrow and that it will be about the Hamtramck and Brownstown facilities and involve the Volt. So, stay tuned.

EcoCar3 will convert Camaro to bitchin' eco rides

In the 47-year-history of the Chevrolet Camaro, there have been countless college-age kids spending a ton of time getting under the hood and souping 'em up. Now, General Motors is adding a twist to the concept by donating 16 Camaros for the EcoCar challenge that puts university teams together to wring out better fuel-efficiency out of various vehicles. No word on whether there will be donuts on anyone's lawn, as suggested by 80's punks the Dead Milkmen, but the idea's never a bad one. EcoCar3 will feature 16 teams such as Arizona State, Penn State, Ontario's University of Waterloo and, of course, Detroit's Wayne State University. They'll spend the next four years "[reducing] environmental impact, while maintaining the muscle and performance expected from this iconic American car," as the EcoCar organizers say. The goal is to maintain body design and safety standards while boosting efficiency and lowering emissions, but the actual process is far more complicated than that description suggests. The California Air Resources Board (CARB) and Bosch are among the sponsors of the contest, which is also put on by the US Department of Energy and managed by Argonne National Laboratory. Penn State won Year Two of the three-year EcoCar 2 competition with its E85 plug-in hybrid electric vehicle converted out of a Chevy Malibu. The grand-prize winner of EcoCar2 will be announced in June. Check out the EcoCar3 website and see the announcement video below for more details. This content is hosted by a third party.
