Fiat offers a few powertrain choices for the 500 that improve the small car's fuel efficiency, like a two-cylinder small displacement engine and the all-electric plug-in option (well, in concept form, at least). A better diesel option will be coming soon with the addition of a new 1.3-liter 16-valve MultiJet diesel engine that improves fuel economy to 60 miles per gallon (U.S.).

Considered a MultiJet II, the new engine offers start-stop technology for lowered emissions (104 grams of CO2 per kilometer instead of 110) and a variable geometry turbocharger for more brake horsepower (95 bhp at 4,000 rpm, up from 75 in the outgoing MultiJet engine). The new engine will propel the 500 all the way to 112 miles per hour (the earlier MultiJet could only manage 103 mph) and drops the 0-60 time by almost two full seconds to 10.7 seconds.

NEW 500 MULTIJET: MORE POWER AND PERFORMANCE; LOWER FUEL CONSUMPTION AND EMISSIONS

The Fiat 500 has been the forerunner of many new technologies and features such as Start&Stop, along with eco:Drive, Blue&Me, and Euro 5 engines. Now, Fiat's popular range of city cars is to be further enhanced with the introduction of a powerful new 1.3-litre 16-valve MultiJet diesel engine.

The range's out-going 75bhp MultiJet unit is being replaced with a more potent but also more environmentally-friendly 95bhp 'MultiJet II' version, which not only boasts improved mpg and CO2 emissions figures, but also incorporates Fiat's acclaimed Start&Stop technology to further reduce fuel consumption when driving around town. The engine will become the most powerful diesel unit available in the A segment.

The new unit introduces an innovative variable geometry turbocharger that enables it to deliver 95bhp at 4000rpm and 200Nm of torque at only 1500rpm. This output significantly improves the car's performance, taking its top speed to 112mph (from 103mph) and reducing the 0-62mph acceleration time from 12.5 to just 10.7 seconds.

Fuel consumption is improved from 67.3mpg to 72.4mpg in the combined cycle, while emissions drop to 104g/km of CO2 (from 110g/km). Together with Start&Stop, the engine also includes a DPF particulate filter for improved emissions efficiency and effectiveness from a cold start.

"This remarkable new diesel engine will add even greater excitement to the fantastic 500 range, but without adding to the cost of ownership," says Andrew Humberstone, managing director, Fiat Group Automobiles UK Ltd. "In fact, with greater fuel economy and lower emissions, everyone will benefit from this new variant
