Fiat is now offering the most popular engine in the 500 range with an enhanced 'Eco' specification.

 The 1.2-litre 69hp 'Eco' is equipped with additional efficiency technologies including a smart alternator, improved underbody aerodynamics and low rolling resistance 15-inch tyres, as well as Start & Stop which is already standard across the 500 range. 

Despite no drop in performance, says Fiat, compared to the standard 69hp 1.2 (0-62mph in 12.9 seconds and top speed of 99 mph), these modifications result in the official CO2 emissions for the 1.2 'Eco' being reduced from 110 to 99g/km which, in turn, cuts the annual road tax bill from £20 to £0 and reduces company car BIK tax liability from 17% to 14%.

Official fuel economy also improves with 58.9 mpg (urban cycle), 70.6 mpg (extra urban cycle) and 65.7 mpg (combined cycle) compared to the standard car's 51.4-, 65.7- and 60.1 mpg respectively.

Available in Pop Star and Lounge trim levels, prices for the Fiat 500 1.2 'Eco' start at £11,865 OTR for the hatchback and £14,515 OTR for the convertible 500C version.
