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.

Autoblog Podcast #327:

Meet the mother-daughter team that's worked on almost every Chevy Volt

It's Mother's Day, and we're soft enough we love our mothers enough to share a new video from General Motors with you. In it, we meet Monique Watson (left) and Evetta Osbourne, a mother-daughter team that works at the Detroit-Hamtramck Assembly where GM makes the Chevy Volt (along with all of GM's other plug-in hybrids: the Opel Ampera, Holden Volt and Cadillac ELR). The two work side-by-side and have installed the lithium-ion battery pack on almost all of those vehicles - nearly 80,000 of them - since GM started making the pre-production Volts in 2009. In a prepared statement, Watson said that she likes working next to her mom, day in and day out, and they the two are totally in sync when it comes to putting the 400-pound, 16.5-kWh packs into the vehicle undersides. They two can also share stories throughout the day, and Watson said, "The arrangement has absolutely improved our relationship." Osborne started working at Detroit-Hamtramck in 1999, Watson since 2006. If you're driving a Volt today, you probably have them to thank for doing a bit of the work putting your car together. See a short video of them in action below. It's Always Mother's Day for Detroit-Hamtramck Duo Mother, daughter install lithium-ion battery pack in nearly all GM electric vehicles 2014-05-08 DETROIT – For Detroit resident Evetta Osborne, every day is Mother's Day. That's because she literally works side by side with her daughter, Monique Watson, at General Motors' Detroit-Hamtramck assembly plant. They have installed the lithium-ion battery pack on nearly every Chevrolet Volt, Opel Ampera, Holden Volt, and Cadillac ELR since production began. In fact, apart from vacation days and an occasional sick day, the mother-daughter duo has installed almost every battery pack since the Volt was in pre-production in 2009. The ELR launched earlier this year. All told – including Ampera – that's more than 80,000 electric vehicles. "We're a good team and our relationship is secondary when it comes to performing our jobs – but it's great to work alongside my daughter, said Osborne, a mother of five. Because the battery packs weigh more than 400 pounds each, automatic guided vehicles – robotic carts that use sensors to follow a path through the plant – deliver them just as the vehicle body structures glide into position overhead. The carts then lift the T-shaped packs, and Osborne and Watson guide them into the chassis and secure each one with 24 fasteners.
