lighter and smaller than conventional engines / incorporates approximately 80% fewer parts / higher power-to-weight ratio / considerably cleaner with fewer emissions / runs on gasoline, diesel, ethanol and on other fuels as well
2-stroke engine with turbocharger / OPOC (Opposed-Piston Opposed-CĂlinder) configuration / 2- or 4-cilinder versions are available / the dual-OPOC engine can be partly shut off in case of light throttle situations / electric and/or exhaust-driven turbocharger (at low gas pressure the boost can be created by the electric motor, when being spun by the turbocharger, the electric motor acts as a generator and produces electricity) / runs on gasoline, diesel and ethanol as well / compact design, simple structure, lower exhaust emissions
Design: Prof. Peter Hofbauer, ex-VW head of powertrain development
4-stroke engine with integrated supercharger / 180° firing sequence / less weight and very compact / simple - only 3 moving parts / smooth turbine like running / same power at half rpm - less wear and longer life
