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.

Weekly Recap: Bentley Bentayga leads luxury SUV charge at Frankfurt

The Bentley Bentayga is launching a new era of ultra high-end sport utility vehicles that will see luxury makers vie for the world's richest and most exclusive customers. The Bentayga is Bentley's first SUV, and it will formally debut next week at the Frankfurt Motor Show. It's loaded with Bentley's best technology and features, led by a 600-horsepower W12 engine. The mission is simple: stop giving up sales to other companies by not having an SUV in its portfolio. "It creates an entirely new category of ultra-luxury SUV, where there are currently few rivals," IHS Automotive analyst Ian Fletcher said in a report. But Bentley and the Bentayga will soon face stiff competition. Archrival Rolls-Royce will produce its own crossover to be built in England, though timing is unclear. Lamborghini has approved plans for a ute that will be assembled in Italy and launch in 2018. Even the sportier British brands are getting into the market. Aston Martin will make a crossover version of the DBX concept shown earlier this year in Geneva, and Jaguar is launching the F-Pace crossover, which will debut in Frankfurt. These new entries will invigorate a segment that's comprised of the Mercedes G63 AMG and the Land Rover Range Rover SV Autobiography, and Bentley is poised to grab a large share of it, Fletcher noted. IHS forecasts Bentayga sales could hit 3,000 units per year in 2017 and 2018, pushing total Bentley sales to more than 10,000 in the next few years. The vehicle will also get plug-in hybrid and diesel variants to widen its reach. The Bentayga is a sales grab, for sure, but Bentley took care to ensure the SUV remained true to the brand. It's laden with the top-shelf wood, leather, and metal, and it comes standard with an expansive panoramic glass roof. It also has intelligent features like electronic night vision and an optional responsive off-road system that can be configured to adapt to eight different settings. It's a different kind of Bentley, but it's a harbinger of things to come for the world's richest luxury makers. Other News & Notes Toyota debuts next-gen Prius Toyota revealed the next-generation of its iconic fuel-sipping hybrid, the 2016 Prius, at an event in Las Vegas. The car promises 10-percent gains in fuel efficiency, though actual figures – and even powertrain specifics – were not revealed. We estimate that could mean about 56 miles per gallon in city driving and 53 on the highway.

Two More Recalls Push GM Total To 4.8 Million In A Month

General Motors announced two more recalls late Friday, bringing to 4.8 million the number of cars, trucks and SUVs the automaker has called back for repairs in the past month. The string of recalls, topped by an ignition switch problem in compact cars now linked to 13 crash deaths, has embarrassed the company and sidetracked its new CEO, who started work just over two months ago. GM has admitted knowing about the switch problem a decade ago, yet it didn't recall any cars until February. The recall delay has brought two congressional investigations and probes by the Justice Department and the National Highway Traffic Safety Administration. Late Friday night, GM announced it would recall 490,000 late-model pickup trucks and SUVs because transmission oil cooling lines weren't secured properly in their fittings. Transmission oil can leak from a fitting and hit hot surfaces, causing fires, the company said in a statement. GM said it knows of three fires and no injuries. The recall affects Chevrolet Silverado and GMC Sierra 1500 pickup trucks from the 2014 model year, as well as 2015 Chevrolet Suburban and Tahoe SUVs and the GMC Yukon and Yukon XL SUVs. All have six-speed automatic transmissions. The Silverado is GM's top-selling vehicle and an important profit center for the company. The GMC Sierra also is among GM's top sellers. Dealers will inspect the transmission oil cooling line fittings and make sure they're securely seated, at no cost to owners. Also Friday night, GM announced the recall of 172,000 Chevrolet Cruze compact cars because the right front axle shaft can fracture and separate while being driven. The recall affects cars from the 2013 and 2014 model years equipped with 1.4-liter turbocharged four-cylinder gasoline engines. If a shaft fractures, the wheels would lose power without warning and the cars would coast to a stop. GM says it has warranty reports of several dozen shaft fractures. It is not aware of any crashes or injuries. Dealers will replace the shafts free of charge. The recall allows dealers to resume selling affected Cruzes. GM issued a stop sale order on the cars Thursday night. The recall also covers about 2,500 replacement shafts used to fix manual transmission Cruzes that were recalled last September. In all, GM has recalled 4.8 million vehicles since last month, two million more than the company sold last year in the U.S.
