Swissauto
Based in Burgdorf, the firm has supplied V4 engines for ELF, MuZ and Pulse 500cc Grand Prix motorcycles and World Championship sidecars.
Development of the new compact and lightweight 108° V4 2-stroke 500 cc engine for World Motorcycle GP; 29 wins, 41 Poles and 3 World champion titles were the remarkable results with this engine.
The ELF Swissauto first appeared in late 1995. Weighing just 37kg, the engine had a three bearing crankshaft and by 1997 was producing 192hp at 12,500rpm.
Swissauto also developed one of the most efficient (35%) internal combustion engines to extend the range of plug-in hybrid electric vehicles.
