’s decision to cut stop producing the Colt subcompact there highlight the a downsizing trend in Europe for Japanese carmakers as the new-vehicle market there shrinks. The European Union will tighten carbon dioxide emission rules from 2012, with a goal of curbing exhaust on new vehicles to an average 130 grams per kilometer by 2015.

Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.
