Jeep Trackhawk: 600 hp?

The Dodge Challenger and Charger both have Hellcat engine options, bringing 707 horsepower to the cars. The Jeep Grand Cherokee Trackhawk has long been rumored, and sources say it will indeed have the same engine, but without the same tuning.

There could be several reasons why it would be detuned somewhat:

Cooling is a major issue with this amount of power, and the Hellcats have goals of high consistency at full power. Competing cars from Chevrolet and Shelby have been slammed for throttling back on the power as they quickly heat up at the track.

The Jeep, unlike the others, is rumored to be all wheel drive, which could allow quicker launches — but would put more stress on the entire system. The engine may have to be tuned to put out the power that can reasonably and economically be handled by the drivetrain and suspension.The Grand Cherokee has a higher center of gravity and too much power could be dangerous.

Regardless, a Jeep Grand Cherokee Trackhawk packing even 580 horsepower would be a major boost over the current 485 horsepower SRT model, and would likely attract even more attention from those who would normally go for a German crossover.

FCA US has already applied for a trademark on the Trackhawk name. The application has passed all the legal hurdles and USPTO approval of registration is now waiting for the company to file a Statement Of Use (SOU) in commerce.

The NEW 2015 Dodge Challenger SRT Hellcat Officially Unveiled

Dodge has officially unveiled the most powerful vehicle to ever wear the Challenger name – the SRT Hellcat – complete with over 600 horsepower courtesy of a supercharged, 6.2-liter Hemi V8. It will be offered alongside the 485-hp Challenger SRT.

The new, force-induced V8 isn’t just the most powerful ever fitted to the Challenger, it’s the most powerful eight-cylinder Chrysler Group has ever built. Power figures aren’t finalized, so expect to see “over 600 hp” bandied about quite a lot. That fury will be channeled through either a six-speed manual or eight-speed automatic. Yes, over 600 ponies through an eight-speed auto. So far, the only vehicle we know of that delivers more output through that many gears is the as-yet untested Chevrolet Corvette Z06. Sadly, we don’t have performance metrics just yet, although if this thing can’t crack four seconds to 60 miles per hour, we’ll be pretty surprised.

As is the theme nowadays, the 2015 Challenger SRT features a number of driving modes, governing power output, shift speeds for the 8AT, steering effort, traction control settings and suspension settings. There are three pre-programmed options – Default, Sport and Track – and a Custom mode that allows drivers to mix and match to their heart’s content.

Like the Ford Mustang Boss 302, the SRT Hellcat will arrive with two keys, one red and one black. The red key is the one we want, as it unlocks the car’s full potential, while the black key is more or less a valet key, limiting output of that supercharged beast under the hood.

Both the SRT Hellcat and the lesser SRT model will ride on unique 20-inch alloys. An eight-spoke design, wrapped in either Goodyear Eagle RSA2 all-seasons or Goodyear Eagle F1 Supercar tires, will be offered on the naturally aspirated model. The Hellcat and Track Pack-equipped SRT will get wider 20s and Y-plus-rated Pirelli PZero Nero tires. Corralling the SRT Hellcat’s 600 ponies will be the task of a set of 15.4-inch, two-piece Brembo brakes with six-piston calipers.

Finally, the SRT Hellcat’s extra oomph certainly demands some aesthetic tweaks. On the exterior, a Viper-like hood scoop dominates the head-on appearance of the 600-hp Challenger. That functional scoop is flanked by an equally functional set of air extractors, while the new vertical-split grille is a styling item borrowed from the 1971 Challenger. And in case all this visual aggression isn’t enough, Dodge has added a very, very conspicuous “SUPERCHARGED” badge to the Challenger Hellcat’s fenders.

Production of the most powerful Challenger will kick off during the third quarter of 2014 at Chrysler’s Brampton, Ontario factory. Expect pricing information to be released closer to launch.
