There are currently no publicly available standard metrics to help consumers understand the overall performance of an electric vehicle. Therefore Electrifying.com has created a smart scoring algorithm that will make it easy to compare cars before buying. Tesla Model 3 and BMW i4 top the list of the UK's Efficiency Rating.
The Electrifying.com Efficiency Rating, known as the E-Rating™, has been reviewed and verified by leading independent industry experts and is formulated using an algorithm that takes into account a number of factors. This includes how well the car converts electrical power into miles on the road, the speed at which the battery can be recharged, and features such as energy saving heat pumps, intelligent brake recuperation and climate control preconditioning. There’s also a ‘secret sauce’ based on their expert team’s experience of driving, testing, and reviewing electric cars in the real world. All electric vehicles were rated on a scale from A++ to E.
According to the E-Rating, Tesla Model 3 and BMW i4 are the most efficient models available in the UK, with a maximum A++ rating. Meanwhile, Mercedes-Benz EQV with an E rating, and the Audi e-tron and the Mercedes-Benz EQC with a D rating showed the worst performance.
The 10,000-mile fare difference between an A++ rated vehicle (Tesla Model 3) and an E-rated vehicle (Mercedes EQV) is £580 ($776). For example, an A+ rated Tesla Model Y will cost £176 ($235) less for 10,000 miles than the Volvo XC40 Recharge. In addition to the additional cost of charging, owners will wait much longer in the least efficient cars. This is partly due to the fact that they consume more energy to move, and because they charge more slowly.
Here’s the list of EVs that have been tested by Electrifying.com and their efficiency ratings, from the best to the worst:
