While fuel prices may be hovering near record levels, there’s plenty of demand for performance – or so Chrysler is betting as it readies the ambitious re-launch of its SRT brand.

The make is rolling out four new SRT models that have been equipped with a new 6.4-liter hemi-engine that delivers not only better performance but also markedly improved fuel economy compared to the old Chrysler 6.1-liter Hemi.

The engine in each of the cars has been equipped with cylinder de-activation technology that Chrysler claims can boost mileage by as much as 25%, while upgraded vehicle dynamics, performance-oriented brakes and race-inspired seats – as well as a new high-end sound system – should appeal to traditional muscle can fans.

The 6.4-liter Hemi V8 produces 470 horsepower and 470 lb-ft of torque and can propel the SRT versions of the Dodge Challenger , Dodge Charger and Chrysler 300 to top speeds of 175 mph. The SRT version of the Jeep Grand Cherokee with its 20-inch, highly stylized wheels – designed to show off the new Brembo brakes – tops out at “only” 165 miles per hour after the vehicle’s ground clearance was reduced by an inch to make the SRT SUV more aerodynamic.
