The most efficient electric car on sale in the UK has been named, with Mercedes and Dacia taking the top spots. According to Auto Express, the Mercedes CLA 250+ Sport Edition leads the list with an efficiency rating of five miles per kilowatt-hour, equivalent to the miles per gallon of a diesel or petrol vehicle.
The premium electric saloon can cover 483 miles on a single charge of its 85.5kWh battery. Auto Express praised the vehicle, noting its 'cutting-edge platform and powertrain' and describing it as 'incredibly comfortable and refined, which is ideal for long motorway journeys.'
In joint first place is the Dacia Spring Extreme 100, a city car that also achieves five miles per kilowatt-hour. Auto Express commented that 'the dinky Dacia Spring is proof that it's not the size that matters, it's how you use it.' The Tesla Model 3 Rear-Wheel Drive took third place with 4.8 miles per kilowatt-hour, offering up to 332 miles of range.
The rankings come as campaign group Transport & Environment urges a new tax on heavier vehicles, including some electric cars. They propose a flat rate of £10 per kilogram above 1,600kg, arguing that current Vehicle Excise Duty does not reflect the true impact of larger vehicles on roads. This could affect electric cars, which are often heavier due to batteries and motors.
