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.

VW, Jeep and Cadillac top list of most-tattooed car brands

Most car enthusiasts own at least one piece of gear with their favorite brand's logo on it. It can be a T-shirt, a pen, a hat, or a garage sign, for example. It takes a much greater degree of dedication to get a car-themed tattoo, and a study suggests this sky-scraping level of obsession is most often found in Volkswagen, Jeep, and Cadillac fans. Compare the Market analyzed Instagram hashtags and posts to compile a list of the most commonly tattooed brands. Volkswagen came out on top, with 5,507 posts; note that anything related to the Wolfsburg-based brand earns it a point, whether it's a logo, a cutaway diagram of the Beetle's air-cooled flat-four engine, or a Touareg V10's firing order. Jeep finished second with 2,139 posts, followed by Cadillac at 1,775 posts. Surprisingly, the fourth spot is occupied by Pontiac, which appeared in 1,609 posts in spite of the fact that it hasn't built a car since 2010. Holden appears near the very bottom of the top-20 chart, ahead of Lamborghini, and its result might be influenced by the fact that General Motors announced plans to shutter it earlier in 2020. BMW and Mercedes-Benz are in sixth and 12th place, respectively. Alfa Romeo doesn't appear in the top 20, though its decades-old Quadrifoglio logo (pictured) can easily be mistaken for a symbol of Irish luck. Searching for posts that show a tattoo of a specific model uncovered even bigger surprises. According to the same study, the most-tattoed nameplate is the Chevrolet Impala, which appears in 823 posts. Odds are the earlier generations, like Dr. Dre's famous six-four, are more often tattooed than the final-generation model, which unceremoniously went out of production in February 2020 without a direct replacement waiting in the wings. Second place goes to the DeLorean DMC-12, which has transcended its status as an esoteric fiasco on wheels thanks to its role as a time machine in "Back to the Future." It appeared in 800 posts. Chevrolet's Corvette takes a distant third with 180 posts, followed by the Volkswagen Beetle (147 posts) and the Mini Cooper (116 posts). All told, car-themed tattoos are relatively rare. To put some of the aforementioned numbers into context, searching Instagram for the hashtag Volkswagen yields over 15 million posts, while the hashtag tattoo appears in over three million publications.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
