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.

2016 Chevrolet Camaro First Drive [w/video]

The Autoblog gang was downright stoked to learn the 2016 Chevy Camaro was next on our test-car docket. Then we found out it was the V6 model. Buzzkill. We were hoping for the snorting V8, or at least the spunky new turbo four-cylinder. The V6? Meh. We've been driving V6 Camaros for, like, six years. It's what you buy if you can't afford anything better, or so say horsepower snobs as they wrinkle their noses and cut their coffee with 93 octane. But after a week with the six-pot Camaro, we'll admit it: we were wrong. The all-new 3.6-liter V6 is strong, sounds good, and is damn fun to drive. Its 335 horsepower and 284 pound-feet of torque appear modest by modern standards, but they power the Camaro to 60 miles per hour in 5.1 seconds with the automatic, or in the case of our manual-equipped test car, 5.2 seconds. That's almost half a second quicker than the new turbo four-cylinder model. Yes, it has the same displacement as the old V6. No, it's not the same engine. Upon closer inspection, the V6's potency shouldn't come as a surprise. This engine is from General Motors' newest family of dual-overhead cam powerplants that launched in the Cadillac CTS and ATS. Yes, it has the same displacement as the old V6. No, it's not the same engine. Don't be fooled, and don't underestimate it at stoplights. The strapping V6 is unsuspectingly good, but it's just one of many improvements for the sixth-generation Camaro. Chevy's coupe is lighter, faster, and more modern looking inside and out. It starts with a rear-wheel-drive chassis donated from the Cadillac ATS, though about 70 percent of the components are unique to the Camaro. The 2016 model is about two inches shorter in length (thanks to a shorter wheelbase) and about an inch has been removed from height and width compared to the 2015 model. These lighter underpinnings jumpstarted the Camaro's weight-loss plan, and thanks to extensive use of aluminum, the V6 with the new eight-speed automatic transmission weighs 3,435 pounds – 294 less than its predecessor (the manual-transmission V6 Camaro weighs 3,448 pounds). The V8, meanwhile, sheds 223 pounds. One by one, these elements would merely enhance how the Camaro drives, but taken collectively, they invigorate the new model. It feels much more confident and agile in all circumstances. Put simply, it's a sportier car.

2022 Chevy Silverado HD gains Multi-Flex tailgate as an option

GM is spreading the Multi-Pro Tailgate love around its truck lineup, and the Silverado HD is the latest pickup to gain the option. Just like the 2021 Silverado 1500, Chevy uses the “Multi-Flex” name for it in the HD, eschewing GMCÂ’s “Multi-Pro” branding for the bowtie vehicles. YouÂ’ll be able to option the tailgate on 2022 model year Silverado 2500HD and 3500HD models. ItÂ’ll be available optionally in every trim, so thereÂ’s no need to grab a more expensive trim to gain access to the trick tailgate — youÂ’re also not required to take it in higher trims. Functionality is the same as the standard Silverado and Sierra.  The primary gate opens and closes like any other tailgate out there. ThereÂ’s a primary gate load stopper that allows you to put the gate down and still keep things from flying out the back (it can also be arranged such that the load stopper is at a higher height by using the inner gateÂ’s stopper). The inner gate folds down perpendicular to the ground to allow closer access to the bed. A full-width step is available if you fold both “gates” down and pop out the inner panel. And lastly, the inner gate can be lowered to use it as a small work space. You can watch the short video above to get a quick run through of all the positions, or scroll through the gallery at the top of this post. Besides the tailgate, Chevy says the 2022 Silverado HD is gaining a new Greenstone Metallic exterior paint color. Other changes for 2022 were not detailed at this time, but Chevy says the trucks with this tailgate should be available sometime this summer. Related video:
