Wolf is a Truck in Excite Truck that is one of the three trucks you start out with in the game (the other two being Boulder and Firefly). Wolf's appearance is similar to a Jeep Wrangler. Wolf's distinctive engine is a low, steady hum, similar to Boulder and a few other trucks, such as Raven, Rad, Wasp, etc.
When three S grades are achieved or ten non S grade races are done, Wolf's special paint job is unlocked. Wolf's special paint job changes a lot of the truck's outer features, such as the removal of the back canvas cover, added roof lights, a large white stripe and two smaller dark blue stripes that run across the top and hood of the truck.
