GM full size SUV hybrids spotted undergoing hot weather testing

Not many details are known about the hybrid system that is set to debut soon in GM's full-size Tahoes, Yukons and the like, but they are getting closer to reality. Proof of such is that they are undergoing hot weather testing, as can be seen in the above picture. While many debate whether hybrid drivetrains are best utilized by full size vehicles such as these, proponents say that helping the economy of the worst offenders is best. Consumers will vote themselves when these vehicles hit the showroom floors.

These vehicles will use the new GM hybrid systems, which are full hybrids, not mild hybrids, so they can run on electric power alone or any combination of electric and gas power.
