Dodge Challenger SRT Hellcat gets 22 mpg

With its crazy 707 horsepower on tap and roughly $60,000 starting price, the 2015 Dodge Challenger SRT Hellcat has been one of the most talked about cars of the summer, maybe even the year. However, there's always been one lingering question about the behemoth that Dodge has waited to answer until now - its fuel economy. The EPA ratings for the muscle car are finally out, and the numbers are actually pretty impressive for a vehicle with this much power.
A 2015 Challenger Hellcat with the eight-speed automatic is rated at 22 miles per gallon highway, 13 mpg city and 16 mpg combined. Opting for the six-speed manual drops those figures to 21 mpg highway, 13 mpg city and 16 mpg combined.
"As the fastest muscle car ever, the Challenger Hellcat can run 10-second ETs [elapsed times] at the track, and then get 22 miles per gallon on the drive home. With a starting price of $59,995, there's nothing else that even comes close," said Dodge and SRT President Tim Kuniskis in the company's release.

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.

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.
