Riding on the GM Theta platform, the unibody is mechanically similar to the Saturn Vue and the Suzuki XL7. However, the Equinox and the Torrent are larger than the Vue, riding on a 112. 5 in (2,858 mm) wheelbase, 5. 9 in (150 mm) longer than the Vue. Front-wheel drive is standard, with optional all-wheel drive. They are not designed for serious off-roading like the truck-based Chevrolet Tahoe and Chevrolet TrailBlazer.
