Chrysler to build Fiat 500 engine in 2010

As reported this morning by WXYZ and repeated by Allpar, Chrysler will build Fiat’s “FIRE” (Fully Integrated Roboticized Engine) in Dundee, Michigan, starting in 2010, for use in the Fiat 500. The engine produces 100 hp at 6,750 rpm and 95 lb-ft of torque at 4,250 rpm; a turbocharged version is being developed. The engine includes MultiAir, a variable valve timing and lift technology which allows for separate timing of each cylinder. The system uses electro-hydraulic valve actuators; a solenoid energized with each rotation of the camshaft regulates the amount of oil sent to the actuator, which controls the amount of lift from completely closed to completely open. The valves can also vary the timing.

The 1.4 liter FIRE engine is the first to use MultiAir, which is planned for both the Chrysler World Engine and Pentastar V6 (though not the Hemi, whose variable cam timing will continue.)
