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.

Dodge Viper to out-Hell the Hellcat with supercharged V10?

The Viper wouldn't be the Viper if it wasn't the most powerful model under the Chrysler umbrella. But with the arrival of the Hellcat engine in the Dodge Charger and Challenger, the Viper has fallen behind in the bragging rights department: where the new supercharged V8 produces 707 horsepower and 650 pound-feet of torque, the naturally aspirated V10 offers "only" 640 hp and 600 lb-ft - gargantuan output figures by almost any other standard, but crucially behind on the SRT power scale. Conner Avenue is going to have to do something about that.
Although the Hellcat's engine reportedly won't fit under the Viper's hood, SRT is now rumored to have another trick up its sleeve: supercharge the existing V10. According to the Pentastar performance enthusiasts at allpar.com, Chrysler has already taken delivery of the first such prototype engines so that it can begin the process of fitting it into an upgraded Viper.
The spooled ten-pot is tipped to produce around 800 hp and 650 lb-ft of torque. More than that and the Viper's drivetrain, chassis and bodywork would have to be substantially reworked. Though beefier transmissions are available, fitting them would reportedly set off a domino-game of changes required to handle the added torque. Which may be something Chrysler would be prepared to do for the next-generation model, but in the meantime, 800 hp could prove enough to put the Viper back atop the Mopar performance ladder where it belongs, and give it an edge against the new Corvette Z06 to rekindle sales.

Chrysler recalls 1.2 million Ram pickup trucks

Chrysler has announced that it will issue three separate recalls that will cover as many as 1.2 million Ram pickup trucks for "steering-system tie rods that may have been misaligned during assembly or steering-system service." The vast majority of these trucks were sold in the United States, though some trucks in Mexico, Canada or overseas will be called in, as well.
The largest of the three recalls covers an estimated 842,400 model-year 2003-2008 Ram 2500 and 3500 trucks. Two smaller campaigns will bring 294,000 model-year 2008-2012 Ram 2500 and 3500 pickups, chassis cabs and 2008 Ram 1500 4x4 Mega Cabs; plus 43,500 model-year 2008-2012 Ram 4500 and 5500 4x4 chassis cabs into the dealer to be checked and repaired if necessary.
This is a very large recall, and Chrysler says it is "casting the net wider than necessary to identify those vehicles that require repair." The automaker estimates that "as many as 726,000 may not need repair."
