The Viking VII-A Lightweight Research Vehicle 850101
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.
