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: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.

Common Dodge Ram 1500 vs. Chevrolet Silverado breakdowns

These two trucks are famous for their ability to get the job done. Still, even the toughest vehicle can have mechanical problems at some time. What if we match the Dodge Ram 1500 and Chevrolet Silverado head to head? Let's find out more about common repairs for each model. Also, learn some tricks to pay for car repairs. Clunky Steering Both Dodge and the Chevy owners sometimes notice bumping and clunking when steering. This might be more noticeable when driving over bumps. The cause is usually different in each truck though. In the Dodge Ram, clunky steering is more likely due to a defective lower ball joint. Replacement costs around $300 - $400, parts and labor. Clunky Chevy Silverado steering is probably a steering rack failure. This problem appears more often in trucks with over 90,000 miles. Silverado steering rack repair will run you up to $1,000 or more. Starting Woes For the Chevy Silverado with over 130,000 miles, you might notice trouble starting. This problem may appear occasionally at first, but it typically gets worse. Excluding a weak battery, the culprit is usually the starter. Replacement will cost you around $330 - $500. Of the total cost, $90 is for labor only. Now the Dodge Ram might make a ticking sound when starting, especially on models with over 94,500 miles. The noise often disappears after the engine warms up. These symptoms may indicate a broken exhaust manifold. Repair costs range from $800 - $900. Burning Oil & Gas Gauge On The Blink Sometimes, the Dodge Ram burns oil much faster than normal. In models with over 125,000 miles, this often points towards a leaky intake manifold gasket. A knocking sound may also appear with acceleration along with possible engine misfire. The cost to repair is around $200 - $300. The Chevy Silverado has its own surprises, especially when you've filled the gas tank but the gauge still reads low. Or the needle fluctuates widely from low to full while driving. In trucks with over 120,000 miles, it's likely due to a faulty fuel sensor. You might need a full fuel pump replacement, which can cost you up to $820, parts and labor. Water Inside And Poor Heat The Ram 1500 rear window has been known to leak. You might notice the back seat and floor wet after a rainstorm. This is more common in trucks with over 65,000 miles. Resealing the Ram 1500 rear window costs around $150 - $250.
