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!"

Jerry Seinfeld doesn't love Sarah Jessica Parker's new Country Squire in latest CiCGC

Comedians in Cars Getting Coffee has finally returned for its fourth season of combining Jerry Seinfeld, a miscellaneous celebrity and a cup of java. But rather than fondly remembering some older piece of automotive machinery, this time around, Seinfeld is utterly unable to keep his hatred of Sarah Jessica Parker's 1976 Ford LTD Country Squire from coming out to hilarious effect.
However, Parker has such a high level of infectious enthusiasm for her recently purchased Country Squire that she seems to win over Seinfeld by the end - at least a little bit. For most of their time together, the two of them drive around Manhattan and the suburbs waxing nostalgic about what things were like when these wagons were ubiquitous.
Since this is actually SJP's car, she and Seinfeld trade off driving duties, and the image above should give you some indication of Seinfeld's reaction to the Sex and the City star behind the wheel. It seems this '70s land yacht might be a little too much for her to handle in New York traffic. Regardless, she is absolutely in love with her Ford.

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.
