GC now features no less than five engine options, one of which is an all-new 4.7L V8 that slots in below the 5.7L HEMI V8. The new 4.7L V8 produces 291 horsepower and 322 ft-lbs. of torque. That's more power and torque than the old 4.7L V8, plus it's more fuel efficient (though Jeep doesn't indicate by how much) and flex-fuel capable. Also available is the 3.0L common-rail Diesel V6, 3.7L V6, 5.7L HEMI V8 and 6.1L HEMI V8 in the SRT-8 model.
