2015 Dodge Challenger SRT Hellcat [w/videos]

Darrell Waltrip once said, "If the lion didn't bite the tamer every once in a while, it wouldn't be exciting." The sentiment behind that aphorism is causing my adrenal gland to wake up as Dodge and SRT drivers and engineers - somber-faced to a man - give me the track talk that will precede my driving the 2015 Dodge Challenger SRT on the circuit at Portland International Raceway. PIR might not be Daytona, and the 707-horsepower Challenger Hellcat might seem tame to a legend like ol' Jaws, but there's a not-small part of me that's thinking about how hard Dodge's fire-breathing kitty might bite.
Just a few hours previous, I'd gotten behind the wheel of the Hellcat for the first time, letting its hyperbole-spitting, supercharged V8 Hemi pull me yieldingly through Portland's morning commuter traffic. Lulled into a cocky certainty by the Challenger's good manners at low speed, I drove the throttle just a hair too deep, too fast when I ran on to the highway ramp. For just an instant the rear tires were utterly drenched in torque, and the back end of the big Dodge loosened up like a drift car on a wet track. Throttle steer lives at the fleeting whim of your right foot in this car.
It was no big thing to lay off the gas and pull the Hellcat back in line as I entered the highway, but the incident did get me to thinking: What will this car do to me on a road course?

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.

Dodge Durango gets performance Mopar options for R/T, SRT

Fiat Chrysler is showing new performance add-ons for the 2018 Dodge Durango R/T and SRT models at the Chicago Auto Show, including the familiar Dodge dual center stripes and a new Mopar exhaust system. The 475-horsepower SRT model, which is powered by a 6.4-liter Hemi V8, will also offer a lowering spring kit and a carbon-fiber instrument panel. The signature two-stripe treatment blankets the three-row SUV from the front to rear fascia and is tailored to the signature NACA duct-hood vent. It'll come in five different colors — bright blue, flame red, gunmetal low gloss (metallic finish), low-gloss black and sterling silver — and retail for $1,195 starting in March. View 7 Photos Mopar developed its new bolt-on performance exhaust systems with Dodge SRT engineers and designers to improve flow and achieve that sweet sound. It features a chromium 304 stainless steel construction to make it more resistant to corrosion, with stainless steel band-style clamps and welded and polished 4-inch tips. It costs $1,595 for the Durango R/T and is available now. On the SRT, the price goes up to $1,850, with the package available in the second quarter. New Mopar springs improve the Durango SRT's high-speed cornering stability and consistency by lowering the SUV an average of 15 millimeters, or 0.6 inches. They were developed with proprietary Dodge SRT data not available to the aftermarket to tune the lowering springs to the factory dampers, giving the vehicle less rear-end squat during acceleration, less nose dive while braking and reduced body roll on corners. MSRP on the package, which is available now, is $325. For just under $2,500 you can get the SRT Interior Appearance Group package, which adds a premium-wrapped carbon-fiber instrument panel and door bezels, Dinamica soft-touch headliner and accent paint on speaker trim rings. The Chicago Auto Show is open to the public Feb. 10-19.
