InsideLine Shootout: 2008 Audi R8 vs. 2007 Jeep Grand Cherokee SRT8
Monday, October 15th, 2007From the article: “With 420 hp at its command, the output of Jeep’s 6.1-liter pushrod V8 matches that of the direct-injection 4.2-liter DOHC V8 in the R8. To help reveal the different personalities of these engines, we ran both car and SUV on a DTS all-wheel-drive chassis dyno.
First, the Audi spun the rollers to the tune of 339 hp, demonstrating a nicely flat torque curve that peaked at 277 pound-feet. Then the Jeep belted out 373 hp and 360 lb-ft. Pick a point anywhere in the Jeep V8’s rev range and you’ll find it generates more torque than the Audi, but this pushrod V8 hits the wall at 6,300 rpm whereas the Audi pulls all the way to 7,900 rpm. This higher-revving nature lets the Audi take better advantage of gearing.”
