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.

Nissan recalls 3.5 million vehicles over airbag sensor

Nissan is recalling 3.53 million vehicles globally – 3.2 million in the United States – because the front passenger airbag may or may not deploy properly in the event of a crash. In affected vehicles, the occupant sensing system may not properly register a person sitting in the passenger seat. Passenger-side airbags in roughly 622,000 Nissan Sentra models built between 2013 and 2016 may deploy in crashes when they shouldn't, such as when a child is in the seat. 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, and LEAF, 2013-2017 Nissan Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60 and Q50, 2014-2017 Nissan Rogue, 2015-2016 Nissan Murano, Chevrolet City Express and 2013 Infiniti JX35 vehicles suffer from the opposite problem. In those models, the airbag may not deploy when it is supposed to. Nissan is aware of at least three crashes where airbags in one of the above models did not function properly, resulting in "moderate injuries." There have already been four recalls since 2013 for similar issues in Nissan vehicles. If you own one of these cars, expect a letter from Nissan in short order (or from GM if you own a Chevy City Express).

SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, LEAF and Sentra, 2013-2017 Nissan Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60 and Q50, 2014-2017 Nissan Rogue, 2015-2016 Nissan Murano, Chevrolet City Express and 2013 Infiniti JX35 vehicles. In these vehicles, the front seat passenger Occupant Classification System (OCS) may incorrectly classify an adult passenger as a child or classify the seat as empty despite it being occupied. As a result, the passenger frontal air bag may be turned off and not deploy in the event of a crash. CONSEQUENCE: If the passenger frontal air bag does not deploy as intended in the event of a crash, the passenger is at an increased risk of injury. REMEDY: Nissan will notify their owners. Chevrolet City Express owners will be notified by General Motors.

Consumer Reports declares most and least loved cars [w/video]

Consumer Reports is crunching the numbers from its annual owner-satisfaction survey, and part of that process is finding out how attached drivers are to their cars. CR simply asks readers of models up to three years old if they would buy the same vehicle again in light of their entire ownership experience, and tallies the results. After looking at the responses for about 350,000 vehicles, it turns out that people really love a certain California-built, electrically powered luxury sedan. That's right, this year's the overall winner was the Tesla Model S with a whopping 98 percent of owners saying they would purchase another one (the Model S also won this award last year, with 99 percent satisfaction). The Chevrolet Corvette Stingray came in a close second with 95 percent of drivers hoping to park another one in their garage. A few models weren't quite so favored, though. The Nissan Versa Sedan was the least loved model among its owners; a mere 42 percent said that they would purchase another. The aging Jeep Compass didn't do much better, with just 43 percent of drivers willing to buy the softroader again. On average, about 70 percent of owners say they would buy their car again, and only four cars ranked below 50 percent in CR's findings. Check out the video above to see some of the winners and losers in a few of CR's categories. If you're a subscriber, you can check out the full list on its website.
