Audi introduces new high-efficiency 2.0L TFSI based on Miller cycle; 190 hp, 47 mpg

Green Car Congress

Owing to a higher boost pressure on the inlet side, the engine attains optimal cylinder charges despite the shorter intake time. Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine.
