Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

C7 Corvette turbo with 1,000 horsepower promised from Hennessey

If you can't wait for the next-generation Chevrolet Corvette ZR1, Hennessey says they will have you covered. The Texas-based company has announced it will offer a spate of upgrades for the 2014 Corvette ranging from a range of bolt-on options all the way up to a 1,000-horsepower, twin-turbo system. Buyers can start with a cold air intake, cat-back exhaust or stainless steel long-tube headers, but Hennessey says it will also offer up three stages of forced induction mayhem should those bits and baubles not provide enough thrust.
Those choices start with a supercharger system good for up to 700 hp, though Hennessey will gladly ditch the blower in favor of two turbos. Doing so will spin the crank to the tune of 800 horsepower all the way up to a certifiably ludicrous 1,000 ponies. There's no word on how much these tricks will cost you - or when they will be available, as we're guessing they haven't gotten their hands on the car yet - but you can head over to the Hennessey site to drop them a line if you're curious.

The Opel GT is the concept General Motors should build for the US

Now is the time. General Motors should double-down on performance cars and build the Opel GT concept that's set to debut next week at the Geneva Motor Show. Better yet, sell it in the United States as the Chevy GT. Consumers are showing a thirst for performance cars not seen in decades. Ford has them coming in waves, with everything from the F-150 Raptor to a hotted-up Fusion. FCA US is unrepentantly building loads of Hellcats. GM should respond. The General's cupboard is hardly bare. With the Corvette, Camaro, and Cadillac's V-Series, GM has more than enough to compete with its crosstown rivals and anything Europe or Japan can throw at it. But there's also an opportunity. There's not many front-mid-engine, rear-wheel-drive, two-seat sports cars out there like the Opel GT concept. A Chevy GT that used that layout and captured some of the concept car's proportions and curves would ignite a different kind of passion in enthusiasts. It would be Miata-like. With Chevy branding, this sports car would be the everyday exotic. The concept has a turbocharged 1.0-liter three-cylinder engine, which makes about 143 horsepower to motivate a structure that weighs less than 2,200 pounds. It can hit 60 miles per hour in less than eight seconds. All of those numbers are within the front-engined Miata's territory. This new Opel is inspired by two great mid-1960s concepts that helped put its design studio, and that of its sister brand, the British Vauxhall, on the map. (The GT concept is also technically a Vauxhall, as the brands are linked in GM's European strategy.) One of them, the '66 Vauxhall XVR remained a concept. The '65 Opel Experimental GT was on the road by 1968. That shows this is doable. There's precedent. The Saturn Sky and Pontiac Solstice shared a chassis with a modern GT during that trio's brief run. If GM ever makes this concept, Opel and Vauxhall should get their versions. But Chevy is the one that could make this car a global icon. Chevrolet GT. Make it happen. News & Analysis News: The potential return of the Ford Bronco is generating a ton of attention. Analysis: That's not news, per se. But when the Bronco6G.com fan site did a rendering of a next-generation Bronco, it almost broke the Internet. Everyone from Automotive News to Jalopnik picked up the illustrations. Our own post has drawn a lot of traffic and passionate responses. People are clamoring for the Bronco's return.
