The term hybrid now applies to gasoline/electric-powered vehicles, and 'crossover' has been used to describe everything from SUV/pickup combinations to car-based vehicles with trucklike features.

Vehicles like the 2005 Ford Explorer Sport Trac are handy, but they're really just short-bed crew-cab pickups. Transformers require a structural doohickey like the Avalanche's midgate, which folds to extend the cargo bed into the cabin.
The Avalanche offers more.
