Jeep should omit the tow select on the 2012 SRT8
Jeep uses an active-valve exhaust system along with cylinder-deactivation to achieve a 450-mile range (manufacturer estimated fuel economy stands at 12/18 mpg) and unlike the last SRT8 Grand Cherokee, this one can tow up to 5,000 lbs. That means no more center exhaust outlet.
The Selec-Trac system works with the adaptive damping suspension and has five modes: Auto (for everyday driving), Sport (for a sportier street ride), Track (firms up body motion and suspension, also automatically turns off traction control) for track duty, Snow (for inclement weather (duh), can transfer 100 percent of the available torque to one rear wheel), and Tow (self-explanatory). The SRT8 rides on 20-inch wheels.
