Dodge Viper ACR reportedly green lit [w/video]

The Dodge Viper might be getting a little more venomous in the near future thanks to a return of the performance-honed ACR trim. According to an anonymous source leaking the info to Allpar, the version would go into production in July as a 2016 model year vehicle. FCA US showed a concept for a future ACR (pictured above) at the 2014 SEMA Show that sported carbon fiber parts for the front splitter and dive planes, plus a picnic-table-sized rear wing. The body also received ducts at the rear to shoot cool air to the differential. A set of 15.4-inch carbon-ceramic brake rotors also brought things to a halt in a hurry. The company promised all the aero pieces were sculpted in the wind tunnel to give the coupe even more downforce. To shed weight, engineers chucked the radio, speakers, carpet and sound deadening out of the interior, and they replaced many bits with even more carbon fiber. All of the tweaks are necessary because the ACR moniker carries serious cachet for the Viper at the track, especially at the Nurburgring. One reportedly did a 7:22 lap around the 'Ring in 2008, and another improved that further to 7:12 in 2011. Autoblog reached out to FCA US for comment about the possibility for the hotter Viper, but the company wasn't willing to comment about any possible, future projects. Related Video:

Hennessey's Dodge Challenger Hellcat cranks out 1,032 hp

Enthusiasts know the Dodge Challenger Hellcat produces 707 horsepower. It's one of the modern muscle-car era's iconic numbers. But for some, that's not enough. Enter Hennessey Performance. The Texas tuners loaded the Hellcat with a twin-turbocharger that works with Dodge's supercharger to boost output to 1,032 hp and 987 pound-feet of torque. Yes, that's an engine dyno rating, not at the rear wheels, but still! It's a little more complicated than a bolt-on booster. Called the HPE1000, the turbo kit has stainless steel headers and down pipes, billet aluminum compressor wheels, and a high-flow air system. There's also an an improved fuel pump, and the engine and chassis are specially calibrated. You also get numbered plaques signed by John Hennessey himself and the engine tech who builds your mill. All of this helps get your Hellcat to 60 miles per hour in 2.7 seconds, and it can do the quarter mile in 9.9 seconds at 142 mph. The Hellcat and it's 6.2-liter blown Hemi V8 are not for the faint of heart. Hennessey makes this Dodge downright demonic.

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.
