Chevy SS prototype spotted wearing Pontiac G8 clothes

Do not adjust your computer screen, you are not seeing the rebirth of the Pontiac brand. General Motors has chosen to use a G8 to disguise a test mule for the latest prototype of the forthcoming Chevrolet SS. The G8 was closely related to the Holden Commodore and Vauxhall VXR, the platform upon which the new Chevrolet performance model will be based. It should come as little surprise, then, that GM has opted to use the cladding from the former G8.
Thought the front clip of this mule is pure Pontiac, note the vents immediately behind the front wheel. That is a distinctive design hallmark of the Vauxhall VXR. Also note that this vehicle is right-hand drive, as the Holden and its Chevy counterpart will be very closely related. That likely includes potential drivetrains. The spy photos of this mule also reveal very wide rear tires, and rear wheels that do not match the fronts.

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.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.
