Fiat is launching its new Multi Air technology, which will apparently radically cut fuel consumption and CO2 in its petrol engines.
The Italian carmaker has already had success with two-generations of common rail direct injection diesel engine technology, Unijet and Multijet.
Other than better economy, power is also boosted by about 10%, while there is a 15% increase in torque.
According to Fiat its Multi Air engines offer better responsiveness across the rev range whilst being considerably more frugal and economical.
The technology, although initially developed for spark ignition engines burning light fuel ranging from petrol to natural gas and hydrogen, could eventually be applied to diesel units too.
The first new engine to be equipped with MultiAir will be the Fiat group’s 16-valve 1.4 litre naturally aspirated and turbocharged engines. The carmaker’s Alfa MiTo will get this engine later in 2009.
