On sale in August, the electrically assisted four-cylinder, front-drive sport/utility won’t thrill technophiles or hard-core environmentalists. Here’s why: Rather than integrating complex, expensive and heavy hardware into the transmission as is done with “full” hybrids from Toyota, Honda and Ford, the Vue is the first application for GM’s “belt alternator starter” system (it appears later in the 2007 Chevrolet Malibu and Saturn Aura). While simpler than other hybrids, it goes beyond the stop-restart system that drew criticism when GM called it a hybrid in its full-size pickup.
