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.

Motorweek goes retro with '80s hot hatch shootout

Motorweek's decades of history on television make it the perfect medium to look back into the automotive past and see how things are different now. It recently added old road test videos to its YouTube channel of the Acura NSX and Toyota Supra, as well as the Ferrari F40. For one of its newest flashback clips, Motorweek has exhumed an affordable five-car challenge of 1986's premiere hot hatches.
By today's standards, this is an eclectic field that features fondly remembered classics like the Volkswagen GTI 16-valve and Acura Integra. However, it also throws in some nearly forgotten contenders like the Dodge Colt Turbo and Ford Escort GT. The angular Toyota Corolla FX16 GT-S rounds out the group.
It's fascinating to watch Motorweek run the quintet through the slalom, down the drag strip and on various roads. What's most striking in this clip is the difference in the definition of a performance car between then and now. With its 16-valve, 1.8-liter four-cylinder, the GTI is the burliest of the contenders with 123 horsepower, but it still takes 8.8 seconds to reach 60 miles per hour. By today's standards, that would make it a plain-jane economy car, and not even a particularly quick one.

Old vs. New: 2014 SRT Viper takes on upgraded 16-year-old Dodge Viper

It's easy to play the "Would you rather have a New X or an Old Y with a bunch of upgrades?" game more often than we care to admit, but the crew at Car and Driver have taken bench racing to the next level with their latest video. In it, the magazine pits a brand-new 2014 SRT Viper against a highly modified 1997 Dodge Viper GTS. There are 16 years between the time this particular GTS rolled off the production line and when the new car bowed, but that doesn't mean the old snake's owners have been sitting on their hands.
Thanks to a spate of modifications, the GTS offers up a better power to weight ratio than the new machine, but is that enough to overcome the technological leap forward represented by the 2014 Viper? We won't spoil it for you. You'll just have to check out the full clip below for yourself.
