According to This is Money, a new efficiency ‘E-rating’ has been launched in the U.K that rates electric vehicles (EVs) from A++ to E depending on overall efficiency.
The rating system has been established by Electrifying.com, a website that provides information and advice to potential EV buyers and existing owners.
Electrifying.com says the purpose of the E-Rating is to give consumers clarity as to which EVs will be better for their bank accounts, and also eliminate the lack of an industry-standard system for calculating EV efficiency in a way that’s easy for anyone to understand.
The E-Rating scale works similarly to energy labels from electronics like washing machines to EPC scores for properties. Efficiency ratings are calculated using an algorithm that takes into account the best use of electricity, charging speed, and onboard features that contribute to making EVs more cost-effective.
The Tesla Model 3, along with the BMW i4, topped Electrifying.com’s E-rating rankings, which included a total of 49 all-electric contenders. Both EVs were rated A++ for efficiency and were the only two to achieve that rating.
The Model 3 was the best-selling car (overall, not just electric) in the U.K. for October, and even became the best-selling premium vehicle across the globe last month.
Tesla’s other electric offerings managed pretty respectable ratings as well, with the Model Y scoring an A+ and the Model S and Model X getting A ratings each.

At the very bottom of the list was the Mercedes EQV MPV — the only car to score the lowest available rating, E. According to Electrifying.com, there is a £500 ($666 USD) difference in annual charging costs between the highest-rated cars — the Tesla Model 3 and BMW i4, and the worst-rated car — the Mercedes EQV MPV.
Of course, this is a competition between fully-electric cars, all of which are sustainable and ultimately good for the environment. E-ratings are simply designed to guide potential EV buyers as to which cars offer the best bang for their buck.
