Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

Chrysler readying Hellcat V8 with Viper-like power

A monstrous supercharged V8 engine could be in store for Chrysler and SRT products, if recent rumors are to be believed. Allpar is reporting that the forced-induction V8 - Chrysler's first, if this goes down - could make its debut this summer.
The story goes that the Hellcat would be based on a 6.2-liter Hemi engine, rather than on the existing 5.7- or 6.4-liter versions of the company's vaunted mill. In any case, the general consensus is that the motor will have gobs of power. Modest estimates call for between 500 to 570 horsepower, with some outliers predicting a figure as high as 600 hp. That figure would put the output would place the Hellcat awfully close to that of the 640-hp V10 in the SRT Viper, too. Allpar contends that a slightly lower powered version would allow Chrysler to keep costs below that of the more powerful Ford Shelby GT500, which might be a sweet spot.
The Hellcat could debut in a number of SRT products. SRT versions of the Charger, Challenger and 300 are all up for grabs, as is the rumored SRT Barracuda.

Fiat-Chrysler shows its SEMA lineup

Fiat Chrysler Automobiles already previewed its 2014 SEMA show lineup with some slick renders. Now, the automaker has finally showed us the actual cars, and among the group there are definitely some that stand out more than others.
Dodge is really showing off its muscle at this year's show with four concepts that all pump up the power of the brand's models. Perhaps most interesting among them is the Challenger T/A Concept (pictured above) in striking Sublime Green and matte black. It's meant to resemble the classic Trans Am racer from the '70s. Under the hood is a 6.4-liter V8, and to fit the vintage style there's a pistol-grip gearshift inside.
The Charger R/T also gets some attention with the Mopar concept that shows off what FCA's aftermarket performance arm can do. Mods include an updated body kit, cold-air intake for the 5.7-liter V8 and a coil-over suspension kit. Beyond that, the Dart R/T Concept looks a lot meaner with a black hood with duct work that leads straight to the air intake. The rest of the compact sedan is dolled up in O-So-Orange paint and is fitted with upgrades to improve handling like a coil-over suspension and big brake kit from the Mopar catalog.
