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!"

Jay Leno is far beyond driven in his 1971 Pantera

Perhaps it's fitting that the band Pantera is known for its heavy metal music, because the DeTomaso Pantera is the automotive equivalent of a metal album. It's short, aggressive and makes a mean sound. It doesn't mess around either, with a Ford 351-cubic-inch (5.75-liter) V8 sending mountains of torque to the rear wheels. This week, Jay Leno takes us on a detailed tour of his '71 to show why it rocks.
There's a regular format to Jay Leno's Garage. It starts with Jay and maybe a guest taking a look at the car and talking about its history, and then they take it out on the open road. However, this video is practically a Pantera buyer's guide. Jay is adamant from the start that the last thing anyone should own is a stock example. To remedy this, he and his guest, the editor of the Pantera Club magazine, take viewers to school about some of the ways to turn them into even better performance machines.
No matter what you do to it, though, the Pantera requires that the driver adapt to it, not the other way around. For example, Jay isn't a big guy by most standards, but he has to cram himself into the cockpit with his shoes off and shirt partially unbuttoned just to go for a drive. Still, once out on the road, it all makes sense with that rumbling V8 and those Italian supercar looks. Scroll down to watch and learn a lot more about this uncompromising '70s performance car.

UK auto magazine says this is the best car commercial of all time [w/videos]

There have been many great car commercials over the years, but is it possible to define the best? Well, Ad Week recently took a crack at it by rating the top commercials of the year by looking at their view counts on YouTube, but Auto Express took a more democratic approach by putting the decision to a vote. Just after Thanksgiving, Auto Express came up with a list of the 20 popular commercials, and it tasked its readers with choosing the winner for the best car ad of all time. The winner? Honda's 2003 commercial for its then-new European Accord titled "The Cog."
While the ad never aired in the US, most car people have surely seen the impressive Rube Goldberg-style spot. In fact, the only commercial on this list that we saw on US television was the Volkswagen ad "The Force," but many of the others have become viral videos, including transforming and dancing Citroën C4. Of the 19 other commercials that vied for the title of best ad of all time, only the Ford Puma "Steve McQueen" commercial gave Honda a run for its advertising money.
