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.
At the other end of the scale, the Mercedes EQV people carrier is the only vehicle to obtain an E. The Audi e-tron and Mercedes EQC luxury SUVs were rated D.
Looking at the miles per kWh alone, the cost difference to cover 10,000 miles between an ‘A++’ rated car (the BMW i4) and a car graded ‘E’ (Mercedes EQV) would be £580.
While the Mercedes and BMW are not competing in the same class, there are still big differences between electric cars which are direct rivals. For example, a Tesla Model Y (rated A+) will cost £176 less over 10,000 miles than a Volvo XC40 Recharge.
Besides the extra cost, owners will find themselves waiting for a charge much longer in the least efficient cars – partly because they use more energy to move, but also because they can take charge at a slower rate. A Vauxhall Mokka can take on power at twice the speed of a Mazda MX-30, for example, while the newest Hyundai and Kia models can add 60 miles of range in under five minutes.
Edmund King, president of the AA, welcomed the arrival of the E-Rating: “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.”
Ginny Buckley, founder of Electrifying.com, said: “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.
“At Electrifying.com we’ve made it our mission to help present consumers with genuinely useful jargon-free information so they can choose the best electric car for them. E-Rating will not only help consumers but also car brands who want to hone their vehicles.”
The only person who got all his work done by Friday was Robinson Crusoe.
Anything i post over three lines long please assume it is an article lol.
