When you can buy a 2013 Dodge Dart later this year, the fastest model you can drive off the dealer’s showroom floor will be packing a 2.4-liter four-cylinder engine, good for 184 horsepower.

That goes to the front wheels only, likely via a six-speed manual or a six-speed dual dry-clutch transmission. While the combination will still provide legitimate entertainment value for drivers, it pales in comparison to the Dodge Dart built up for Travis Pastrana’s 2012 Global RallyCross Championship (GRC) season.

Pastrana’s Dart gets an impressive 600 horsepower, via extensive and not-legal-for-road-use modifications. It also gets all-wheel-drive, which gives the race-prepped Dart better odds at getting the power to the ground.

Pastrana will debut the car at the 2012 GRC season-opener, scheduled for May 26 at the Charlotte Motor Speedway. Other stops for GRC include the Texas Motor Speedway on June 9, the summer X Games Los Angeles on July 1 and the New Hampshire Motor Speedway on July 14.

While technically not connected to SRT Motorsports, the Dodge Dart RallyCross car is the second race car we’ve seen from the Chrysler Group in as many days, and we see that as a sign of good things to come.

Yesterday, SRT president and CEO Ralph Gilles introduced the competition-only 2013 SRT Viper GTS-R, simultaneous to the 2013 SRT Viper street car. The new Dodge Viper GTS-R is expected to make its American Le Mans Series debut this summer.
