COE (cab over engine) trucks may look stubby, but they're every bit as powerful as their conventional compatriots. The K-100 Aerodyne was made in a time of tough government regulations which limited the length of semis and necessitated putting the driver right over the powerplant. Kenworth dates back to 1923, when Edgar Worthington and Frederick Kent started the company in Seattle. They helped pioneer the COE design. Kit features detailed 6 cylinder diesel, moving front wheels, and opening doors.
