The Viking VII shows that high performance and excellent fuel economy can be obtained in one vehicle if superior aerodynamics and extremely low weight are realized. An aluminum semi-monocoque chassis tub and advanced composite body shell provide a light weight stiff and crashworthy structure. Extensive use of aluminum in the engine, transaxle, wheels, suspension, brakes and steering allow further weight savings. Extensive wind tunnel testing has resulted in a drag coefficient of .26. A reclining seating position and severe tumble home on the greenhouse gives a frontal area of only 13 ft.2
Development of a 16 valve DOHC boxer engine provides 133 BHP at 7,000 RPM. The use of a compound carburetor for each cylinder allows high performance without compromising low load fuel economy.
