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.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

Recharge Wrap-up: U of M wins Solar Challenge, family attempts record-breaking e-bike ride

The University of Michigan Solar Car Team has won the 2014 American Solar Challenge. It is the team's eighth national championship, its fifth in a row, and its first using Siemens' product lifecycle management (PLM) software. The race took place over 1,722 miles and seven days traveling across eight states. The team's car, called "Quantum," outpaced the nearest competitor by four hours. Looking forward, Michigan Solar Car Project Manager Pavan Naik says, "The switch to Siemens tools will give us the ability to model and simulate everything and truly allow us to optimize the performance of our new vehicle. As we start on our quest to win the World Solar Challenge in 2015, we'll be leveraging a full complement of PLM solutions." Read more in the press release below. The EcoCar3 competition, in which teams will convert Chevrolet Camaros into hybrid electric cars, begins in September. The various college teams will have four years to lessen the car's environmental impact as much as possible while maintaining performance and, of course, that cool Camaro design. EcoCar3, which is put on by the US Department of Energy and General Motors, kicks off with a workshop in Novi, Michigan from September 16 - 18. Read more at the DOE website at the dedicated EcoCar3 site or watch the announcement video at our previous post. Zap and Jonway Auto are shifting to a high rate of EV production. Zap already has two lines creating the Urbee EV to met demand, and is switching over a third to make electric minivans and SUVs. The company aims to produce 30,000 EVs by 2015 for the Chinese market. Zap says it has a backlog of 25,000 Urbee orders. Read more in the press release below. A family of four hopes to make a world record-breaking, 6,000-mile electric bike journey this fall. The family, which recently drove from Argentina to Montana in a pickup with a camper, will ride from Montana to Maine, then down the East Coast to Florida in an attempt to break the record for longest electric bicycle ride. They'll use two bikes. The Father, Thomas, will ride one of the bikes carrying one of the children, while the rest of the family rides in a support vehicle, with the mother, Dylan, riding the second bike when they can find others to drive. They have started a crowdfunding campaign for some of the equipment needed to document the trip. See the video below or read more at Treehugger.
