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.

IIHS gives good ratings to 4 of 8 midsize pickups in crash test

Versions of the Toyota Tacoma, Chevrolet Colorado and GMC Canyon Crew Cab earned top ratings in a new crash test of midsize pickup trucks from the Insurance Institute for Highway Safety, while two versions of the Nissan Frontier earned marginal ratings. But the organization gave poor marks to all eight pickups tested for their dim headlights. Overall, four of the eight pickups evaluated earned good ratings for protecting occupants in all five crash test categories — the Tacoma double cab along with crew cab versions of the Colorado, Canyon and Tacoma. But the poor headlights and lack of an automatic emergency braking system blocked any of the pickups from qualifying for the IIHS's Top Safety Pick awards. The study looked at two pickup body styles using 2017 models: crew cabs, which have four full doors and two full rows of seating, and extended cabs, which have two full front doors, two smaller rear doors and compact second-row seats. It subjected each to five tests, and it evaluated the performance of front crash prevention systems and headlights. The Toyota Tacoma crew cab was the only pickup in that class that earned a good rating for structure in the small overlap test, which replicates what happens when a vehicle clips a tree, pole or another vehicle that has crossed the center line. The model's Access Cab extended-cab version was rated similarly, though its structure was rated acceptable. "This group of small pickups performed better in the small overlap front test than many of their larger pickup cousins," says David Zuby, the Institute's executive vice president and chief research officer. "The exception was the Nissan Frontier, which hasn't had a structural redesign since the 2005 model year." The extended-cab versions of the Chevy Colorado and GMC Canyon earned acceptable ratings, while both the Nissan Frontier king-cab and crew-cab models were rated marginal. Toyota says its 2018 Tacoma will feature upgraded headlights and a standard autobraking system that can detect pedestrians. "Headlights are basic but vital safety equipment. Drivers shouldn't have to give up the ability to see the road at night when they choose a small pickup," Zuby said.

GM finds steering flaw, decides it doesn't warrant a recall

Guess what? General Motors is back in the spotlight for not recalling something. This time, though, not only does the company have an argument against a recall campaign, but its position is supported by the National Highway Traffic Safety Administration. According to The New York Times, over 50 owners of GM vehicles have reported instances of stuck or seized steering after driving long distances without moving the wheel. One owner complained to NHTSA that the "locked" steering of their 2013 Buick Verano caused a collision with a concrete barrier in a construction zone. Along with the 2013 to 2014 model year Verano sedans, Chevrolet Cruze and Malibu sedans are also affected. Considering the popularity of those models, GM needs to have a reason for not issuing a recall, right? "Based on a very low rate of occurrence – ranging from less than one half to less than two incidents per thousand vehicles – and the fact that the condition is remedied when the wheel is turned, GM determined this was not a safety issue," spokesman Alan Adler told The Times. The company has, however, issued a technical service bulletin for owners that complain of the problem. The fix is nothing more than a software update that is covered for 10 years or 150,000 miles from new. NHTSA cited GM's actions, along with descriptions of the problems from customers, in its decision not to issue a recall, with spokeswoman Catherine Howden saying, "the symptoms described would be a brief, perceptible change in steering feel that has little to no effect on the driver's ability to safely steer the vehicle." "When terms like 'notchy,' 'stick,' 'slip' or 'feel' are used, it does not indicate a meaningful increase in steering effort," Howden told The Times via email. What do you think? Is GM in the wrong here? Should there be a recall, or is the issue so limited as to not warrant one? Have your say in Comments.
