The Sport Trac Adrenalin is a new vehicle based on the current Explorer. Tuned by SVT, the Adrenalin offers true performance credentials, such as a supercharged/intercooled V-8, 6-speed automatic, AWD, and fully independent suspension. Huge 21-inch alloy wheels show off the Brembo ventilated disc brakes. An aggressive blacked-out grille hints at the Adrenalin's serious performance potential. The composite cargo bed has lockable storage compartments. Bolstered sport seats are upholstered in bright red and black leather. According to Ford, the Adrenalin is the successor to the F-150 Lightning.
