Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

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 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.
