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.

Brits recreate iconic Bullitt chase scene

Recreating the famous chase scene from Bullitt has become almost an art form in its own right. We've seen it done in a music video, with scale models and even in commercials. There are few films that are as defined by a single scene as the 1968 classic. Even if you don't know a single beat of the plot, the Highland Green Ford Mustang racing a Dodge Charger through the hilly streets of San Francisco is famous. It's so well known that the Silverstone Classic has created a homage to promote its celebration of the 50th Anniversary of the Mustang at this year's event in July.
Filmed around the famous UK circuit, the short film generally gets the key points of the scene right. It even has a green Volkswagen Beetle that keeps reappearing, as in the movie. Unfortunately, its Steve McQueen stand-in looks a little too old for the role. While the video shortens the chase considerably, it's still great to see these '60s behemoths leaning and sliding around the track. Scroll down for a touch of nostalgia thanks to one of the greatest scenes ever in cinema - we've got both the recreation and the original chase seen from the movie waiting for you.

2015 Dodge Challenger SRT Hellcat with '600-plus horsepower' officially unveiled [w/video]

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.
