479 ftlb of torque would be awesome but the 149 hp would let most people down. 0 to 62 in 15 seconds is slow. Perhaps the X is lighter? I doubt it. Ill take my SC X anyday even with its low gas mileage.
Don't understimate the bennefits of torque especially if you're planning on adding oversized tires. And if you don't want to sacrifice HP you can get a 4.8L gasoline engine with 248 HP and 310 lb-ft, all with better offroad options.
