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.

Dodge Scat Packages add Mopar performance upgrades in three stages

Dodge has revealed what it calls Scat Package Stage Kits that enhance the performance of the Charger and the Challenger equipped with the 5.7-liter V8, and the Dart equipped with the turbocharged 2.4-liter inline four-cylinder engine. The Scat Packs use Mopar performance parts that also can be bought separately. Most of the upgrades increase engine output, but Dodge somehow manages to not specifically mention the power gains associated with each Scat Pack.
The three Scat Packs offered for the V8-powered cars focus on higher power ratings, and each stage comes complete with a unique engine-management calibration to optimize output. Stage one comes with a cold-air intake and a cat-back exhaust; stage two adds a performance camshaft; and stage three really gives you the goods, adding ported polished cylinder heads and performance headers.
For the Dart, the Scat Packs focus on engine, transmission, chassis and brake upgrades. Stage one will net you a cold-air intake, a short-throw shifter and slotted rotors with performance brake pads; stage two adds a cat-back exhaust system and an engine-management calibration to increase output by taking advantage of premium-octane gasoline; and stage three adds 13-inch vented brake discs up front clamped by four-piston calipers, suspension with adjustable springs and struts and performance front and rear antiroll bars.

Dodge Viper production to end after 2017

We can't say we're surprised, but we're still saddened to report that the Dodge Viper will not live on past the 2017 model year. It's had a solid 25-year run, though, and that's worth celebrating. Fiat Chrysler Automobiles does just that for the Viper's final model year, with five special editions (some of which seem less special than others, admittedly): The 1:28 Edition ACR, GTS-R Commemorative Edition ACR, VoooDoo II Edition ACR, Snakeskin Edition GTC, and Dodge Dealer Edition ACR. Instead of running through what makes each of these 2017 Vipers special, we'll direct your attention to the press release below and the images above. All but the Dodge Dealer Edition commemorate memorable Viper models of the past 25 years, and the GTS-R is probably the pick of the litter with its classic blue-on-white paint scheme. Unless you prefer to err on the side of gaudy, in which case Dodge has you (and your car) covered with Snakeskin Green. If none of these special-edition Viper models strikes your fancy but you'd still like to park a 2017 Viper in your garage, fret not. Dodge is still offering its "1 of 1" customization program for the Viper's final year of production. Finally, instead of dwelling on the past, even when that past is as exciting as the Viper's, let's choose to look to the future with the only logical question left unanswered: What's next?
