Cleanest engine of the future prize aims at reducing the pollution produced by future new vehicles using either gasoline or diesel fuels and their low biofuel blends available on the market.
Powertrains/cars in which the improvements are achieved by using significant amounts of fuels or stored energy other than the main fuel (i.e. plug-in electricity, mild and full hybrids, stored compressed gases, etc.) are excluded.
Submissions shall aim at very significant noxious emissions improvements while at the same time reducing fuel consumption and CO2 emissions and providing sufficient dynamic performance for normal vehicle driving.
