GM has been talking about their upcoming full-size SUV hybrids for a while now and there has been lots of speculation about how great they will be.

Well thanks to Automotive News we now have a better idea of the improvements that the hybrid powertrain brings to the line. Both GM SUVs will achieve 21mpg in the city and 22mpg on the highway (2WD). Compare that to non-hybrid that gets 14/20 for the 2WD with the 5.3L V8. The 4WD hybrid versions will achieve 20/20. The 2WD hybrids post a 50 percent improvement over the regular non-hybrid versions in the city.

The two-mode hybrid system is mated to a 6.0L V8 and together the system achieves 332 horsepower and 367 ft-lbs. of torque. The hybrid versions are also capable of towing 6,000lbs. We’ll have to wait and see what the premium is for these SUVs once they start arriving at dealerships.
