The most popular Smart car is also its most affordable - the Smart EQ fortwo. As of the middle of 2022, it was the cheapest EV to buy new in the UK, coming in much cheaper than the Fiat 500 Electric or the Nissan Leaf.You get a range of up to 80 miles between charges, a top speed of 81mph and while there’s only room for two people, there’s a decent 350 litres of luggage space. The EQ forfour gets the same 17.6 kWh battery as the EQ fortwo, and can be recharged to 80 per cent in around three hours.
