Watch a Dodge Challenger Demon break 200 mph

We all know that the Dodge Challenger Demon is a monster in short bursts. Its 840 horsepower and drag-ready tires allow it to hit 60 mph in a claimed 2.3 seconds on the way to a sub-10-second quarter-mile time. But it turns out that the Demon doesn't run out of grunt after the quarter-mile. This was proven by a group that took one to the runway where space shuttles landed, Johnny Bohmer Proving Grounds in Florida. There they hit a top speed of 203 mph. Dodge doesn't give a top speed for the Demon, but for a bit of comparison, the 707-horsepower Hellcat Widebody has a top speed of 199 mph. Watching the video, it's interesting how calm things appear to be in the cabin. There doesn't appear to be much vibration, and the car was clearly staying steady in a straight line, since the driver hardly moved the wheel. And before you know it, the 2.3-mile run is over. The run's not official unless a record-keeping body is witnessing it, and there will surely be Demons out there trying to beat this run, but it's sure fun to watch in the meantime.

Inner Demon revealed: 840 hp and other jaw-dropping details

After months of teasers, rumors, cryptic messages, and veiled hints, the 2018 Dodge Challenger SRT Demon is finally here, and it's as wonderfully insane as we hoped it would be. Finally we know the facts and figures that Dodge has been hinting at for so long. 840 horsepower. 770 lb-ft of torque. 2.3 seconds to 60 mph. A quarter-mile run of 9.65 @ 140 mph. While pricing hasn't been announced, Dodge is trying to keep it under $100,000. That horsepower figure makes this the most powerful production V8 ever. With those 0-60 and quarter-mile times, it's also NHRA certified as the quickest production car ever. Someone with the means needs to line a Demon up against a Tesla Model S P100D. All that power and all of the Demon's trick launching software and hardware will throw a driver back against their seat with 1.8 Gs. Drivers will be seeing a bit of sky, as the Demon is the first production car to pull a wheelie from a dead stop. Yes, this is all totally and 100 percent street legal. View 48 Photos In order to make all this power, the red-painted supercharged 6.2-liter Hemi V8 has been significantly improved over the Hellcat. It's equipped with a larger 2.7-liter supercharger that turns the boost up to 14.5 psi, redlines at 6,500, and has what Dodge is calling SRT Power Chiller, a system that uses the air conditioning to cool the air coming in through the new Air Grabber hood scoop. In order to keep your engine running time and time again, there is an after-run cooler than cools the supercharger after the car is shut off. The pistons and connecting rods have been strengthened to deal with the higher load. In order to feed enough juice into the engine, the Demon uses dual fuel pumps. We assume that a decent EPA rating wasn't on the top of the engineer's list. Oh, and the Demon can run on 100-octane with the press of a button. With the traditional SRT black and red keys, the Demon actually has three horsepower ratings: 500 with the black key, 808 with the red key, and the full 840 with the red key and 100-octane fuel. Don't worry, even if you have the black key, the Demon will drop the 1/4 mile in 11.59 seconds, still quicker than almost anything around. Most of the rest you already know from the seemingly endless teasers. The Demon wears lightweight wheels with sticky 315/40R18 Nitto drag radials at all four corners.

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!"
