2015 Dodge Challenger SRT Hellcat revving is sonic bacon

This is the Dodge Challenger SRT Hellcat, and we're sure that by now, you know its stats, including over 600 horsepower from its 6.2-liter, supercharged V8. What, pray tell, does that blown engine sound like, though?
At least judging on the sonic strength of this video, it's very, very dirty. Honestly, it sounds unlike anything that's come out of the Chrysler Group in a long time, if ever. It's loud, almost brutally so, with a bark that few road-going V8s can match.
Of course, you should be the final judge here. Take a look and a listen at the two videos below, one of which comes from our friends at Cars.com that provides a nice look under the hood, and then let us know what you think of the Hellcat's singing voice in Comments.

Chevy Corvette Stingray defeating rivals where it matters most

Everything is coming up roses for the award-winning Chevrolet Corvette Stingray, as new data from the North American Dealers Association dissected by GM Authority reveals that America's sports car is handily outselling two of its more expensive rivals.
Through June of 2014, the NADA notes that the Corvette has rung up 17,744 sales, handily besting the Porsche 911 and positively spanking the SRT Viper. Of course, you're sitting there thinking, "Corvette is outselling the much more expensive Porsche and Viper. Sky blue, water wet." But what's impressive here is just how thoroughly the Chevrolet is beating its two rivals, with this data serving as a testament to just how popular the seventh-generation sports car has become.
So far this year, Porsche has managed to move 5,169 911s, according to NADA. Considering that the base model starts at nearly $15,000 more than the most heavily optioned Stingray, and that Porsche owners have a vast, expensive options catalogue to select from, Stuttgart's sales are still plenty impressive in relation to the nearly 18,000 Corvettes sold.

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!"
