Here are the Challenger SRT Demon's bare-minimum performance numbers

This week's Dodge Challenger SRT Demon teaser video provides what seems like more concrete evidence than any of the others before it. We say it seems that way because the numbers flashed on the screen are likely not showing us everything the car has to offer. So we're looking at these as the minimum performance stats and expecting Dodge to reveal even crazier numbers alongside the car next month. The video also provides some hints at features and modes the car will offer. Let's pick it apart. First off, there's the performance data from the various SRT Performance Pages screens. The 0–60 mph time is 3.0 seconds, which compares well to the "regular" Hellcat's 3.5-second manufacturer claim. Then there are two 0–100 times: 6.08 and 6.8. An eighth-mile time of 6.6 seconds at 125 mph and a quarter-mile time of 0.5 seconds at 129 mph lead us to believe the driver lifted off the throttle in that second eighth-mile and that the car will actually do the quarter in the low 10s. For reference, Dodge claims an 11.2-second quarter for the Hellcat on its street tires and a 10.8 with race slicks.

A graph shows it heading up toward 10 psi but the final spike is obscured by a Demon head. Cute. There's a hint at horsepower and torque numbers in a graph on the Dyno page, which shows both peaking around 750. In every shot of this video, the clock is set to 7:57, which we think means it either has that much power or, well, more. We think there's more to it because it appears that part of the graph above the dyno run shown, which would reach to 800 or 850, has been blanked out. A horsepower total of 808 would be a nice complement to the Hellcat's 707, don't you think? We can see from the shift indicator screen that the car will come with or at least offer the eight-speed automatic that's also available in the Hellcat and other Challengers. That's likely to be the best option for drag racing. The Demon's user-defined shift light feature, which lets you choose an optimal shift rpm for each individual gear, also suggests that a six-speed manual will be available. We'll cover the many modes and settings highlighted in this video in a separate post. There's a lot to discuss. Related Video: This content is hosted by a third party.

Dodge Challenger Hellcat valet mode angers parking attendant

I spent over three years as a valet. It was good money and an excellent second job when I was getting my start as a writer – ten hours per week at the small restaurant I worked for was good for anywhere from $150 to $250. Over those years, I can say with absolute confidence I never goofed off in someone's car. Unfortunately, not all valets are so trustworthy. Like these idiots. Apparently, a Dodge Challenger Hellcat owner captured the valets at Universal Studios in Florida on his dashcam messing about behind the wheel of his 707-horsepower muscle car. One valet is behind the wheel and there's another riding shotgun as they aimlessly wander about the parking lot, lamenting the fact that the owner (wisely) engaged valet mode before handing over the keys. "We can't do anything," they whine. The owner, for his part, seemed pretty cool about the whole thing, writing in the YouTube description that he purposely kicked up the exposure at the end of the video to hide the identities of the valets. He also added that they didn't do anything wrong – this former valet agrees to disagree, based on the over four minutes it takes to actually park the car – and that he was thankful for valet mode. You can check out the video above – be warned, though, there is some language in it. And remember, if you valet your car, use valet mode, check the odometer when you drop off and pick up, and if everything checks out, give the poor guys a tip. Want more recent Hellcat news?

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!"
