Summary

Nowadays the scooter market class L1e (<50cm³, speed limited to 45km/h) is dominated by low-cost two-stroke carburetted engines. With the implementation of the new EURO 3 regulation, obligatory for new type approval by 2014 and for all newly licenced types by 2015, the market will suffer the loss of these low cost vehicles due to the requested durability of exhaust gas after treatment systems. More complex drive units, like lambda controlled 4-stroke engines or 2-stroke engines with direct injection will have to follow. Pure electric scooters pose a further possibility to fill the resulting gap. A significant cost increase is common to all of these approaches. Necessary additional system components will cause the increase for ICE variants, whereas battery costs are responsible for the electric variant. The goal is to find an alternative to be able to comply with the requirements of emission legislation and to keep the product price as low as possible at the same time.
