Annual Running Cost (Â£) = Cost per mile x Average mileage /100. The Renault Clio takes about 40 litres to fill up and travels 400 miles on a full tank, giving it a respectable MPG of 45. This equates to around 10.5p/mile assuming that the Price of Petrol is around 105p per litlre. For a Renault Clio.
According to a spokesman for Renault, using the Twizy to drive 130 miles a week would equate to roughly Â£3 per week - or Â£156 a year - based on three charges a week and domestic electricity at 14p/kwh unit. The car is small, allowing a driver and one passenger behind, so is intended as a city run-around.
