when did they start making the jeep srt8
Jeep Grand Cherokee The new Grand Cherokee SRT8, which started production on July 16, 2011,[21] is equipped with a 470 hp (350 kW; 480 PS) 6.4 L Hemi V8 engine. Jeep claims the new SRT8 gets 13 percent better fuel economy than its predecessor.[citation needed] To keep the gas mileage respectable,[clarification needed] Jeep has employed a new active exhaust system that lets Chrysler's cylinder-deactivating Fuel Saver Technology operate over a wider rpm band. Chrysler claims that with the larger gas tank, the SUV can now travel up to 500 miles (800 km) on a single tank, while other sources estimate range to be 450 miles (720 km).
