Maybe a hybrid would help.
Hummer was created in the mid-1990s, back when it was cool to drive a big, aggressive SUV. Now, fuel economy is cool and even a relatively efficient Hummer, like the mid-sized H3, is seen as a gas hog.
The strategy for Hummer is to go small and broaden its line-up, building on its image as maker of serious off-road equipment while losing its reputation for selling just big, fuel-thirsty SUVs. (The new V8-powered H3 Alpha, shown here, seems like an inexplicable throwback, given the current agenda.)
GM is considering a Hummer pick-up as well as a small SUV to compete directly with the Jeep Wrangler.
A gas/electric hybrid Hummer is also being seriously considered. Such a vehicle would be fully off-road capable. In fact, the electric motor's strong low-end torque could be a selling point. Also, you'd have a built-in elecrical generator for use at the campsite.
One thing Hummer will not do, GM says, is make a Hummer that cannot go off-road. Of course, Jeep used to say that, too.
