Hennessey Dodge Demon sets hellishly fast quarter-mile time

The Dodge Demon doesn't strike us as a muscle car much in need of a performance makeover. After all, this 840-horsepower MoPar machine's voracious quest for straight-line speed means it trims weight by jettisoning everything from a front passenger seat and rear seat, to its stereo and all carpeting in the trunk. The folks at Hennessey apparently think that's not nearly extreme enough. So, the Texas-based tuning outfit has turned the Demon into a 1,035-horsepower mega beast that runs a quarter-mile in 9.14 seconds at 152 mph. That's fast, really fast. In fact, the HPE1000 is now the world's fastest Dodge Demon, having set its record-setting pace at Lonestar Motorsports Park on May 8. "The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car's impressive track times to an industry leading level." said president and company founder, John Hennessey. For comparison, the stock Dodge Demon is credited with running the quarter-mile in 9.65 seconds at 140 mph. The main HPE1000 modification involves replacing the stock 2.7-liter supercharger with one that's a staggering 4.5-liters in capacity. Also included in the Hennessey toy-chest are stainless steel long tube headers, a high-flow air induction system, upgraded throttle body, upgraded fuel pump and fuel injectors, along with custom engine management calibration. When all is said and done, the HPE1000 Dodge Demon delivers a total of 1,035 horsepower at 6,500 rpm and 948 pound-feet of torque at 4,200 rpm. While the standard Demon accelerates from 0-60 mph in only 2.3 seconds, the Hennessey variant trims this down to only 1.9 seconds. That's quick enough to make a Bugatti Chiron blush. Hennessey hasn't stated what all this will cost, though the company did say production of these devilishly fast Demons will be limited to only 50 examples. Customers also receive a 1-year/12,000-mile warranty, which seems a nice touch for a car that's downright scary with its performance specs.

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.

Special Dodge Challengers get Hellcat bits to celebrate Mopar's 80th birthday

This year, Mopar is celebrating its 80th anniversary, and it's doing so in two-tone style with this very limited edition Dodge Challenger. Only 160 of these Challengers will be built, with 80 in each paint scheme. Buyers can choose between either Billet Silver or the slightly painful sounding Contusion Blue, each of which gets a hand-painted Pitch Black top half. These Challengers are based on the existing 392 Shaker package, but come with an array of upgrades and tweaks. In addition to the custom two-tone paint, the shaker scoop and rear spoiler are painted in the same color, rather than the usual matte black. The cars come with 20-inch wheels and hand-painted 392 logos on the fenders. The 392 cu. in., or 6.4-liter if you prefer, engine produces the same 485 horsepower and 475 lb-ft of torque as its normal counterpart. This Mopar Challenger will have more access to cold air, though, since it has both the shaker scoop and the headlamp intake from the Challenger Hellcat. At the back, there's also exhaust tips borrowed from the most hellish of Challengers. Or at least the most hellish, so far. View 14 Photos Inside, the changes are more minor. Performance seats are added with embroidered Mopar logos in the backrests. The seats and other trim also feature a silver-colored Tungsten stitching. Naturally, a serial number badge makes an appearance inside, too. Owners will also receive a little box of goodies including a booklet, signed rendering, keychain, additional badge, and a certificate showing the date of manufacture. The overall package is rather attractive, but it isn't cheap. To own one of the few Mopar Challengers, you'll have to fork over $56,885. That's a significant premium over the 392 Scat Pack Shaker, which starts at just $44,890 and makes just as much power. You'll also be able to get a 392 Scat Pack Shaker right away, while the Mopar special edition won't be out until spring. Plus, you may not get it until summer because the hand-painting process takes some time. Of course, for some people, the cost and the wait are worth the exclusivity.
