A ground-breaking new efficiency ranking standard – E-Rating™ – has been launched by Electrifying.com to give electric car buyers clarity on the most efficient models available in the UK, with the BMW i4 and Tesla Model 3 headlining the top of the E-Rating™ leaderboard.
By choosing a more efficient electric car based on the E-Rating, electric vehicle drivers could save more than £500* in annual charging costs alone.
While consumers understand miles per gallon and the energy labels on their home appliances, until now there was no publicly available, industry-standard figure to help buyers comprehend the overall efficiency of an electric car. The E-Rating’s smart algorithm turns complex factors into a simple to understand score from ‘A++’ down to ‘E’, helping buyers choose the right car for them, saving money and time at the charger.
The E-Rating brings the car industry in line with other consumer sectors and has undergone stringent verification and testing by independent experts. It was formulated using an algorithm that considers several important factors; these include how well electrical power is converted into miles on the road, the speed at which the battery can be recharged and features such as heat pumps, intelligent brake recuperation and climate control preconditioning that all help to minimise power use.
Topping the podium, the BMW i4 and Tesla Model 3 are considered the most efficient models available in the UK with maximum A++ ratings. While the Mercedes EQS, Citroen Ami and e-C4, and SEAT Mii are among 13 models to reach A+ ratings, with a further 14 performing well enough to achieve an A.
