Alfa Romeo has introduced a new downsized engine to the compact MiTo that will improve output while cutting fuel consumption and emissions. The so-called MultiAir 1.4-liter four cylinder is available in normally aspirated and turbocharged variants in three power levels: 105, 135 and 170 hp. The key to the MultiAir concept is an electro-hydraulic valve control that allows the engine management system to directly control the intake valves in response to driver acceleration demands without a throttle. BMW has had the same concept on its six cylinder engines for several years under the ValveTronic name.

The MultiAir system allows the engine to produce 10% more power and 15% more torque while consuming 10% less gas than a conventional throttle version of the same engine. CO2 emissions are also cut by 10% while particulates and NOx are cut by 40% and 60% respectively. The MiTo with MultiAir will be available in Europe starting in September.
