EV efficiency rating launched

Published:  30 November, 2021

An efficiency ranking standard for EVs available in the UK has been launched by Electrifying.com: The E-Rating.

The top vehicles in the ranking are the BMW i4 and Tesla Model 3, while the Mercedes-Benz EQV and Audi e-tron were rated least efficient. The most efficient electric cars can be over £500 less to charge up across the year based on an annual mileage of 10,000 miles.

The E-Rating’s score goes from A++ down to E, and was formulated using an algorithm considering how well electrical power converts into miles on the road, battery recharge speed, as well as the impact of heat pumps, intelligent brake energy recuperation and climate control preconditioning.

Commenting on the E-Rating, AA President Edmund King said: "Anything that helps consumers decide on the most efficient EV for their needs in simple terms can only be a positive thing.Drivers need to research a range of factors based on their individual needs before deciding on any type of vehicle, and efficiency is a major factor for many.Electrifying.com introducing this new tool for electric car buyers makes the process of picking the right electric car for them a much simpler and easier-to-understand process.”

Electrifying.com founder Ginny Buckley added: “It amazes me that until now we haven’t had an effective efficiency standard for electric cars, as we do across other sectors; but we’ve looked to put this right. As electricity costs less than petrol or diesel, it is easy to dismiss the efficiency of electric cars and think it isn’t important. But the costs of a less efficient model can soon add up. Perhaps more importantly, an electric car that is more frugal will go further and spend less time charging, meaning greater convenience for consumers.
