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!"

Now's the time to buy a cheap first-gen Chevy Volt

Would you fork over 18 grand and change for a new Chevrolet Volt extended-range plug-in vehicle? If so, there are some for the taking. Since the updated Volt is about ready to hit dealerships, current models have become a lot easier to afford. For some reason, it appears the best deals are in Iowa, recalling some sort of Field of Dreams-style whispering voice luring car shoppers to their first plug-in vehicle, according to EV Obsession. To wit, a couple of 2014 Volts with a sticker price in the $35,000 range are being offered for less than $26,000 in that Midwestern state. Factor in the $7,500 tax credit from the federal government, and the Volt can be had for less than the sticker price of a Toyota Prius C compact hybrid. Chevy started priming that particular pump earlier this year, though didn't appear to have a ton of success. This past spring, Chevrolet was offering some impressive lease deals on the Volt, with monthly payments dropping to less than $250. There's a reason buyers will want to wait for the second-generation Volt. The 2016 version will have a 53-mile all-electric range, up from the 38-mile range in the current version, along with 106 MPGe. Some will say that the style is improved as well, and the first-gen's touch-sensitive control panel was discarded for more buttons. Still, if you're more concerned about price than having the newest car on the lot, now's a good time to shop. And speaking of the current version, sales remain down substantially. Last month, Chevy moved 1,380 Volts, a 45-percent plunge from a year earlier. Through August, Volt sales were down 37 percent this year compared to 2014 numbers, to 8,315 units.

Why the Corvette is Chevrolet's billion-dollar baby

Edmunds has worked up a piece that tries to figure out just how much the global Chevrolet Corvette economy is worth, a spitballed guesstimate putting the number at more than $2.5 billion with the proviso that the number is probably low. It starts by taking Corvette's new car sales of 14,132 units last year, which would equate to $714,725,900 (including destination) assuming ever car sold was a base coupe with no options. In the final tally, a little extra padding gets that number up to $750,000,000.
But that's not all. Consider this: Many of the almost 1.4 million Corvettes produced over the model's history are still on the road. There are new parts being produced and aftermarket companies like Mid-America Motorworks deaing business, that single Illinois company doing more than $40 million a year in sales. There are the Corvette events large and small, restorers who do nothing but Corvettes, salvage yards that deal only in used Corvette parts and the Corvette magazines where owners find all this stuff.
And then there are the Corvette-themed tchotchkes, every single one of which provides a tiny contribution to the huge licensing royalties that General Motors collects every year. The article admits there's no way to come to an accurate number, but it just goes to show how valuable one specific model can be to a company.
