The AT4 goes back to 17-inch wheels in Gloss Black, and to further its supposed off-roading prowess, it comes with standard all-wheel drive and skid plates. It does have a higher ground clearance than the base model, but this is by no means an off-roader. Other differences include front sill plates, the AT4 logo embossed into the seat upholstery, and a higher starting price.
