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!"

2013 Chevy COPO Camaro announced with two new engines and manual option

Chevrolet is following up the 2012 COPO Camaro with another limited run of the drag-strip-ready production car for 2013. Ditching the superchargers, the 2013 COPO Camaro can only be equipped with one of three naturally aspirated V8 engines, and other new features include the option of a manual transmission, new front springs, some minor styling changes and a lower starting price of $86,000. All cars are designed to abide by the rules of the NHRA's Stock Eliminator or Super Stock classifications, depending on in which series buyers wish to enter their Chevrolet Camaro.
Returning for 2013 is the 427-cubic-inch V8 producing 425 horsepower, but the new engines include a 325-hp 350-CID V8 and a 375-hp 396-CID V8. Buyers can select to purchase all three engines, and each will be matched with the sequence number of that car; the track-only COPO cars will not have vehicle identification numbers and can't be registered for street use.
Chevrolet is also offering unique enthusiast-specific options such as a COPO Build Book and the opportunity for owners to help assemble their car's engine at the Chevrolet Performance Build Center in Wixom, MI.

Chevy rolls out Silverado HD High Country

It's been a good week for heavy-duty truck buyers. First, Ram revealed the Black Package for its HD trucks, then it rolled out its new Power Wagon, and now Chevy's getting in on the action with its Silverado High Country HD. Okay, so it may not pack quite the attitude of Ram's latest 2500-series offerings, but the High Country HD will come as a welcome addition to the Chevy Trucks range to those looking to pull their horse, boat or other trailer without skimping on creature comforts.
Rolled out a little under a year ago, the High Country trim is Chevy's answer to the likes of the GMC Denali, Ford King Ranch and Ram Longhorn. It has until now only been offered on the light duty, 1500-series Silverado, but now extends to the 2500 and 3500-series HD models, as well.
So what sets a High Country pickup apart from lesser Chevy trucks? You'll be able to pick it out based on its chrome horizontal grille, body-color bumpers, 6-inch tubular side steps, 20-inch chrome wheels (18-inch on the 3500 and 17-inch on the dualie) and, of course, plenty of special badging. But it's inside where the High Country makes its mark, with a cabin decked out in saddle brown perforated leather, seats that are both heated and cooled, eight-inch touchscreen with full MyLink suite, Bose audio and park assist functions front and rear to keep those color-keyed bumpers looking fresh. (Though Chevy hasn't yet showed us the interior of the HD model, it'll presumably look mostly the same as the cab in the 1500 High Country in the gallery below.)
