Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.

Marchionne says no offers are on the table for Fiat Chrysler

MONZA, Italy (Reuters) - Fiat Chrysler (FCA) has not received any offer for the company nor is the world's seventh-largest carmaker working on any "big deal", Chief Executive Sergio Marchionne said on Saturday. Speaking on the sidelines of the Italian Formula One Grand Prix, Marchionne said the focus remained on executing the company's business plan to 2018. Asked whether FCA had been approached by someone or whether there was an offer on the table, he simply said: "No." The company's share price jumped to record highs last month after reports of interest for the group or some of its brands from China. China's Great Wall Motor Co Ltd openly said it was interested in FCA, but had not held talks or signed a deal with executives at the Italian-American automaker. The stock move was also helped by expectations that the company might separate from some of its units. Marchionne reiterated on Saturday that FCA was working on a plan to "purify" its portfolio and that units, such as the components businesses, would be separated from the group. He hopes to complete that process by the end of 2018. "There are activities within the group that do not belong to a car manufacturer, for example the components businesses. The group needs to be cleared of those things," he told journalists. Asked whether an announcement could come this year, Marchionne said it was up to the board to decide and that it would next meet at the end of September. He said the time was not right for a spin-off of luxury brand Maserati and premium Alfa Romeo and the two brands needed to become self-sustainable entities first and "have the muscle to stand on their feet, make sufficient cash". "The way we see it now, it's almost impossible, if not impossible, to see a spin-off of Alfa Romeo/Maserati, these are two entities that are immature and in a development phase," he said. "It's the wrong moment, we are not in a condition to do it." He said the concept of separating the two brands from FCA's mass market business made sense and did not rule out this happening in future, but not under his tenure, which lasts until April 2019. "If there is an opportunity in future, it would certainly happen after I'm gone. It won't happen while Marchionne is around," he said.

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.
