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.

Chevrolet Suburban Luggage Test: How much fits behind the third row?

From the very beginning of doing these luggage tests, I specifically had no intention of doing one for the Chevy Suburban or any extended-length full-size SUVs. Quite simply, there was no question that my six suitcases were going to fit behind the third row. And not only that, I was pretty confident there'd be a ton of space left over, much as there is in mid- and full-size two-row SUVs.  And yet, you know what vehicle I've received more requests for cargo-related information about over the years? That's right, the Chevrolet Suburban. Sure, it's not exactly BTS fan mail volumes, but it's more than anything else. Apparently, people want to know how much fits in the back of a Suburban (or GMC Yukon XL ... or Cadillac Escalade ESV). So, when a Suburban popped up in the press fleet I decided to finally give the people what they want.  As a reminder, this is the amount of cargo space behind the THIRD row of a Suburban. Chevrolet says this is 41.5 cubic feet, and it sure looks like it.  For the record, the most stuff I've ever put into the back of a three-row vehicle is a Honda Odyssey, which has 32.8 cubic feet of space. I never did another minivan after that, for reasons effectively described above. And no one has asked for it. Now, because I'm greedy, I lifted up the floor to see if there's any underfloor space. Wow, there is! Theoretically, it could lower the floor a bit and allow for even more stuff, but the floor's hinges don't allow it. Unlike those in a BMW that can be propped into an upright position, these'll just drop the floor back down again. That's OK, I won't use this then. Let's get to the bags. As with every Luggage Test, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two black roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller green roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D). So yeah, it all fits. No surprise there. In fact, there's even more room leftover than I anticipated.  Let's go to the extra (and imaginary) items, then! First up, the trusty 38-quart Coleman cooler. This added to my bags, plus maybe a duffle bag, is what big "compact" SUVs like the Kia Sportage and Toyota RAV4 can manage.

Recharge Wrap-up: Chevy hits CO2 goal, eVgo and BMW build fast charging

Chevrolet has met its goal of preventing 8 million metric tons of CO2 emissions over the last five years. Through its community-based carbon reduction initiative, Chevy invested $40 million and took part in 38 different projects in 29 different states. The projects included supporting wind farms, powering a hospital with landfill gas, helping truckers reduce their idle time and helping create the ongoing #CleanEnergyU dialogue between students and clean energy leaders. In the end, Chevy retired all its carbon credits rather then spending them to offset its own emissions. Read more from Chevrolet. NRG eVgo and BMW are partnering to add DC Fast Combo charging to locations around the country. Over the next two years, the groups will bring hundreds of the 50-kW chargers to 25 cities, with 24 of those markets getting at least one installed by the end of 2015. "eVgo will add reliable DC Fast Combo capability to what is already America's largest DC Fast charging network," says eVgo President and CEO Arun Banskota. "This will be the fastest and most cost effective build out of a new network ever – thanks in large part to our existing infrastructure and committed retail host partners." Read more in the press release from eVgo. The EPA has settled with a Utah gasoline refiner over Clean Air Act violations. The HollyFrontier Corporation subsidiaries will pay $1.2 million for producing about 42 million gallons of gas that didn't adhere to Reid Vapor Pressure standards, resulting in 10 excess tons of volatile organic compound emissions. Its Salt Lake City refinery will also implement a program to offset past emissions. "This agreement will benefit public health by requiring retrofits of storage tanks at HollyFrontier facilities that will reduce volatile organic compound emissions and use next generation technology to verify these reductions," says Assistant Attorney General John Cruden. "This settlement shows that fuel refiners can and must meet the nation's standards for controlling the emissions that cause ground level ozone and serious health problems for Americans."
