GM issues stop-sale for 3 SUVs over incorrect MPG rating

This week, GM sent a memo to Chevy, GMC, and Buick dealers to tell them to stop selling three SUVS. The 2016 Chevy Traverse, the GMC Acadia, and the Buick Enclave all have EPA window stickers that show higher fuel economy ratings than the vehicles actually have. Unlike other recent – and very public – fuel economy ratings problems from VW and Mitsubishi, it doesn't seem like GM did anything wrong with the testing for these vehicles, it just misprinted the labels. New labels are being printed and should arrive at dealerships this weekend and early next week. After that, the SUVs will be able to be sold and delivered again. The official fuel economy rating for the three SUVs are all the same. The correct numbers for the all-wheel drive versions are 17 miles per gallon combined, 15 city, and 22 highway. The stickers say the SUVs get 17/24/19. The front-wheel driver models were also incorrectly labeled, and the total number of affected vehicles is 59,823. In the memo, GM said the problem was caused by an "inadvertent error," Automotive News says. GM is working with the EPA to solve the issue. We have asked GM for a comment on the mistake and will update this post if we hear back. Related Gallery 2013 GMC Acadia View 16 Photos News Source: Automotive News – sub. req.

Genovation Cars readies all-electric Corvette prototype

Chevy runs the full spectrum from some of the most environmentally friendly cars to the least. At one end are EVs like the Spark and Volt. At the other, performance models like the Camaro and Corvette. But one American company wants to bridge that divide. That company is Rockville, MD-based Genovation Cars, which reports that it is almost done building its prototype for an all-electric Corvette. Dubbed the Genovation Extreme Electric (or GXE for short), the prototype is based on a previous-generation 2006 Chevy Corvette Z06, but ditches its enormous 7.0-liter V8 for an array of inverters, batteries, and electric motors said to be good for over 700 horsepower and 600 pound-feet of torque. That promises to deliver a 0-60 time of about 3.0 seconds and a top speed in excess of 200 miles per hour. Those are supercar benchmarks for performance if we've ever seen them, and ought to leave even the top-spec Tesla Model S P85D in... well, not a cloud of smoke, but whatever the electric equivalent is, in a non-polluting cloud of that. The GXE is also supposed to be able to travel for 150 miles on a single charge, and handle well while it's at it with 50/50 front-rear weight distribution and a low center of gravity. Sorta like the Power Wheels 'Vette pictured above, then, but bigger and faster. Look for the GXE to debut at the Electric Vehicle Technology Expo this coming September in Michigan, after which Genovation says it will put the GXE to the test on the track to back up its performance claims. Genovation Cars Nearing Completion of High-Performance All-Electric Corvette, the GXE ROCKVILLE, Md.--(BUSINESS WIRE)--Genovation Cars is nearing the completion of a prototype high-performance all-electric Corvette called the Genovation Extreme Electric or GXE. Assembly of the GXE will be completed by the end of July, followed by a three-week testing phase. The GXE is based on a 2006 Z06 Corvette. Several contributors to the GXE effort have helped design and build record-breaking electric vehicles. They include an MIT electrical engineer and a mechanical engineer from Cosworth. "We are using state of the art inverters, batteries and electric motors that will produce in excess of 700-hp and 600 lb-ft of torque," said Genovation CEO Andrew Saul. "We expect the car to achieve 0-60 mph in around three seconds and have a top speed of over 200 mph.

2017 Chevy Bolt charged up for production

Chevy's decision to call its new electric car the Bolt has stirred controversy and confusion, but regardless, it's well on its way to becoming a production reality. The prototype captured in these shots is heavily camouflaged, but the crossover/hatchback styling cues are still evident. The car also has a tall greenhouse, slight creases in the sides, and a sloping roofline in back. There's a rapidly rising body line that makes for less glass for rear passengers, but that's probably part of the camo. The Bolt is expected to arrive for 2017 and will be sold in all 50 states. The Chevy Bolt carries the promise of bringing EV technology to a broader audience. Chevy said the car will cost about $30,000 after possible tax incentives and could have a range of 200 miles. It will be assembled at General Motors' Orion Assembly factory north of Detroit. The Bolt will augment the plug-in hybrid Volt in Chevy's green fleet, and it will compete against vehicles like the BMW i3 and Nissan Leaf. Related Video:
