Global trends show an increasing approval of electrified mobility due to advantages like local zero emission and low noise. But range anxiety, missing comprehensive availability and high costs significantly obstruct the acceptance and growth of electro mobility. Extended research on finding innovative solutions focus on the elimination of the disadvantages of pure electric drivetrain systems. Therefore an ICE range extended electric vehicle is a promising approach. Commonly, small-capacity gasoline engines with low cylinder numbers are used for range extending applications. Targets are low emissions, efficient packaging, good NVH behaviour and low costs. In this paper the layout and design of an innovative two-stroke twin-cylinder engine with a capacity of one litre is presented. Compared to conventional single- or twin-cylinder four-stroke engines a two-stroke engine has better running smoothness due to the ignition sequence of 180 degrees.
