2015 Dodge Challenger SRT Hellcat with '600-plus horsepower' officially unveiled [w/video]

Dodge has officially unveiled the most powerful vehicle to ever wear the Challenger name - the SRT Hellcat - complete with over 600 horsepower courtesy of a supercharged, 6.2-liter Hemi V8. It will be offered alongside the 485-hp Challenger SRT.
The new, force-induced V8 isn't just the most powerful ever fitted to the Challenger, it's the most powerful eight-cylinder Chrysler Group has ever built. Power figures aren't finalized, so expect to see "over 600 hp" bandied about quite a lot. That fury will be channeled through either a six-speed manual or eight-speed automatic. Yes, over 600 ponies through an eight-speed auto. So far, the only vehicle we know of that delivers more output through that many gears is the as-yet untested Chevrolet Corvette Z06. Sadly, we don't have performance metrics just yet, although if this thing can't crack four seconds to 60 miles per hour, we'll be pretty surprised.
As is the theme nowadays, the 2015 Challenger SRT features a number of driving modes, governing power output, shift speeds for the 8AT, steering effort, traction control settings and suspension settings. There are three pre-programmed options - Default, Sport and Track - and a Custom mode that allows drivers to mix and match to their heart's content.

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!"
