The smallest vehicle the Air Raider can call upon (unless exploding Roombas are counted as vehicles), the SDL1 is a high-powered sport motorcycle fitted with a sidecar that mounts a surprisingly potent machine gun. The driver has no weapon, and it is necessary for another player character to get in the gunner's seat to drive and shoot at the same time. It is the fastest vehicle in either game, though this is something of a double-edged sword in practice.
