That price includes the £3500 plug-in car grant and is for the entry-level hatchback-only Action car, which is powered by a 94bhp electric motor capable of 0-62mph in 9.5sec and an 84mph top speed. The variant's 23.8kWh battery offers a WLTP-certified range of 115 miles and can charge at speeds of up to 50kW.
Prices climb to £23,495 for mid-range Passion trim, which can be specified in cabriolet form for an additional £2650. Fiat claims the new 500 is the world’s first four-seat convertible EV. Its roof is a sliding fabric top, as before.
This version gets the larger 42kWh pack so can travel 199 miles on a charge - significantly up on the 144 miles offered by the new Mini Electric and more in line with the 211 miles from the Peugeot e-208 - and is capable of charging at 85kW. Power output is boosted to 117bhp for a 0-62mph time of 9.0sec.
The 85kW rapid-charging system can recharge the battery from empty to 80% capacity in 35 minutes and can take just five minutes to provide the car with 31 miles of range, which, Fiat claims, is more than the needs of most people’s average daily use.
The 500 Passion is marked out from the base-level car by its 15in two-tone wheels and LED daytime running lights and is equipped as standard with a 7.0in touchscreen, smartphone compatibility, cruise control and climate control.
Icon trim caps off the range at £24,995 in hatchback guise and £27,465 as a drop-top. Added equipment over the Passion car includes a 10.25in 'cinerama' high-definition touchscreen, 16in alloys and colour-coded dashboard.
Fiat has also unveiled a new '3+1' option, which adds a reverse-opening rear door on the passenger side for ease of entry to the back seat. The option adds 30kg to the 500's overall weight but is claimed to have "no effect" on handling or range. There's no word yet on whether the 3+1 will come to the UK, but Fiat said it "will firstly be made available for left-hand-drive markets".
