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.

2014 Chevy Silverado High Country spied wearing trappings of new luxury trim

Spy photographers have spotted the new Chevrolet Silverado High Country and GMC Sierra Denali out on public streets for a little testing. From the looks of things, the Silverado will receive a much-differentiated front fascia along with special badges and those honking 20-inch chrome wheels. Expect to find a more posh interior as well. Likewise, the Sierra Denali will wear a tweaked nose with the familiar Denali bling. The one of the GMC trucks spotted here rolls on 21-inch gunmetal wheels instead of the 20-inch chrome pieces of the High Country.
Word has it both trucks will go on sale after the Texas State Fair this summer. While General Motors hasn't said for certain what we can expect to find under the hood, we'd be surprised to see anything outside of the range of engines found in the standard Silverado and Sierra models. That means buyers should be able to get their hands on the efficient, 23-miles per gallon 5.3-liter V8.

Ford also working on 200-mile EV to compete with Bolt, Model 3

The Chevrolet Bolt is on a lot of people's radars. You may have even noticed friends and colleagues who harbor very little interest in the automotive world, or anything labeled as "green," who have taken notice of a 200-mile electric vehicle coming out of Detroit. Mass appeal is the idea, after all. You can include Ford in the list of interested parties, in this case with the intention of taking direct aim at the Bolt – and, by proxy, the Tesla Model 3 – with an affordable, long-range EV of its own. Ford will unveil its own long-range EV, positioned to compete with Chevrolet, later this year, according to Automobile. Details are very scarce about Ford's plans, but we do know that the Bolt (or whatever the Chevy all-electric hatchback will end up being called) is expected to offer over 200 miles of driving between charges, with a sticker price around $30,000. The other major player, of course, is Tesla's smaller, more affordable sibling to the Model S. The Model 3, also slated to go on sale in 2017, should cost less than $40,000. While Tesla has established itself in the EV world, another long-range EV out of Detroit would win some customers from the California-based startup. For now, though, we'll just have to wait, as Ford remains tight-lipped about its plans for the car. Automobile predicts a possible unveiling at the Los Angeles Auto Show in November, what with California's EV mandate being a driver of strategy for various automakers. Most can agree, though, that a larger field of options – while not ideal for backers of the Bolt or Model 3 – will only benefit the car-buying public.
