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!"

What is the fastest car in the world in 2024?

It wasn't that long ago that the notion of reaching 200 miles per hour in a car, on a road, seemed basically impossible. As you likely know by now, that time has passed. And once that threshold was crossed, the automotive world immediately began eying the next triple-digit benchmark: 300 miles per hour. It may have taken a little while, but the 300-mph line has been crossed, and some cars have moved well past that seemingly insane speed number. While some of these speeds have been achieved in simulations (including the fastest car listed below), there's little doubt that a driver with nerves of steel and a heavy right foot could indeed push several automobiles up to 300 miles per hour and beyond. Interestingly, it’s not just one car or automaker in the 300-mph club, as a handful of models have earned a place (sometimes claimed but not yet demonstrated) on the leaderboard. The fastest car in the world is: Koenigsegg Jesko Absolut (330 MPH) That title goes to the Koenigsegg Jesko Absolut, which recorded a staggering 330 mph top speed earlier in 2023. The carÂ’s twin-turbocharged 5.0-liter V8 lays down 1,600 horsepower and 1,106 pound-feet of torque, which plays a significant role in delivering that speed, but KoenigseggÂ’s engineers have given the car a lot more than mind-blowing power. The Jesko Absolut has a super-slippery 0.278 drag coefficient and a nine-speed transmission that shifts so quickly itÂ’s almost imperceptible. Koenigsegg calls it a Light Speed Transmission (LST), saying its shifts happen at almost light speed. While that might be a slight exaggeration, the gearbox is impressive, bringing several wet multi-disc clutches and a super lightweight construction. As Koenigsegg says, "the Jesko Absolut is destined to achieve higher, more extraordinary speeds than any Koenigsegg or any other fully homologated car before it." How expensive is the Koenigsegg Jesko Absolut? If you were reading that and wondering how much the fastest car in the world costs, the price tag is just another dizzying number on the Jesko Absolut's spec sheet. All 125 Absolut cars offered sold out at a price of almost $3 million. Of course, being able to afford the Koenigsegg is just the first step in realizing its full potential. There are very few places on the map that can support a 300-plus-mph speed run, and the locations that do are not conveniently located.

Dodge Viper ACR reportedly green lit [w/video]

The Dodge Viper might be getting a little more venomous in the near future thanks to a return of the performance-honed ACR trim. According to an anonymous source leaking the info to Allpar, the version would go into production in July as a 2016 model year vehicle. FCA US showed a concept for a future ACR (pictured above) at the 2014 SEMA Show that sported carbon fiber parts for the front splitter and dive planes, plus a picnic-table-sized rear wing. The body also received ducts at the rear to shoot cool air to the differential. A set of 15.4-inch carbon-ceramic brake rotors also brought things to a halt in a hurry. The company promised all the aero pieces were sculpted in the wind tunnel to give the coupe even more downforce. To shed weight, engineers chucked the radio, speakers, carpet and sound deadening out of the interior, and they replaced many bits with even more carbon fiber. All of the tweaks are necessary because the ACR moniker carries serious cachet for the Viper at the track, especially at the Nurburgring. One reportedly did a 7:22 lap around the 'Ring in 2008, and another improved that further to 7:12 in 2011. Autoblog reached out to FCA US for comment about the possibility for the hotter Viper, but the company wasn't willing to comment about any possible, future projects. Related Video:
