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.

Recharge Wrap-up: Tesla sells Model S 85 and 70D in Malaysia, Chevy Spark EV built using clean energy

Tesla will send Model S 70D and Model S 85 EVs to Malaysia for leasing to government-linked companies. Only those companies will have access to the models as a two-year lease, which will be imported and leased by Malaysian Green Technology Corporation. The plan is part of an initiative by the Ministry of Energy, Green Technology and Water to allow government officials and other influential people to get to know the electric vehicles and the benefits that come along with them. Most of the 120 vehicles available will be the 70D model, and the lessee companies will have the option to purchase the cars at the end of the two years. Read more from Paul Tan's Automotive News. Wanxiang is hosting students from Delaware in China as part of a program to learn Mandarin and visit schools and science and technology sites. Wanxiang, the auto parts company that acquired Fisker (which had manufacturing based in Delaware) and battery maker A123 Systems, will give the students tours of its solar technology facilities, among other places, and see what daily life is like for families in the region. The program helps students interested in science and technology to foster marketable skills — like learning a foreign language — that will help them get jobs in industries around the world.

The e-motors building of the General Motors Baltimore Operations complex has a new rooftop solar array and uses LED and CFL lighting, helping the building recently earn LEED Silver certification. The landfill-free facility also takes advantage of the 1.23-megawatt solar array on the grounds, helping it source six percent its energy from renewable sources. The plant has reduced its energy intensity by 15.5 percent in three years, and continues to work toward reducing consumption and sourcing clean energy. "We believe reducing our environmental footprint is good for the climate and good for our business," says GM Executive Director of Global Public Policy Greg Martin.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.
