Fiat is launching a new 95hp version of its 1.3-litre 'Multijet II' Euro5-compliant diesel engine in the 500 model line, along with new rear suspension.

The new engine, with start-stop as standard, was developed and is produced by FPT - Fiat Powertrain Technologies. One of a second generation of Multijet motors, it has new common rail injectors with balanced hydraulic servo valve to control the amount of diesel injected into the combustion chamber with a high degree of precision, making the injection sequence much faster and more flexible than previously (up to 8 injections in the same cycle). This allows better control of the diesel combustion with benefits for consumption, emissions, noise levels and driveability, Fiat said.

The engine has a variable geometry turbocharger that ensures optimum turbocharging throughout the entire operating range. Fuel consumption has been reduced by up to 8% in the urban cycle thanks also to the start-stop system that switches the engine off temporarily and then restarts it.

A particulate filter is standard.

A new rear torsion beam (semi-independent) suspension with an anti-roll bar is now used on the standard 500 range. It was first developed for the sporty Abarth 500 model and has already been introduced on the 500C convertible. It gives better handling and a more comfortable ride, according to Fiat.
