According to Fiat sources, Chrysler may use its new partner’s MultiAir fuel-saving technology in some gasoline engines. Fiat considers its variable valve timing system a breakthrough since it reportedly increases horsepower and torque while reducing fuel-consumption and CO2.
The MultiAir technology basically controls air and combustion in engines cylinder by cylinder, without using the conventional throttle system. The MultiAir system first made its debut in the new Alfa Romeo MiTo hatchback in 3 different output levels including a 105-hp, 135-hp and 170-hp.
Insiders say that Fiat’s MultiAir technology could be applied to the 2.0L and 2.4L 4-cylinder engines that are produced by Global Engine Manufacturing Alliance (GEMA) by 2011. The engine will be used in the Chrysler Sebring, Dodge Caliber, Dodge Avenger, Jeep Compass and the Patriot.
The Pentastar V6 engine family could also get the technology in the second half of 2012. It will be fitted with the 3.6L V6 and will debut in the 2011 Jeep Grand Cherokee.
