The most efficient electric cars have been revealed: the new rating system tops the BMW i4 and Tesla Model 3, but Audi and Mercedes are considered bad


Electric vehicles are generally considered to have better environmental benefits than petrol and diesel cars – but which EVs are more efficient?

A new ‘E-Rating’ has been launched that ratings for how efficiently each model sold in Britain is used, saying that the annual charging cost between good and bad cars is £ 500.

Of the 49 models already rated by Electrifying.com, the BMW i4 and Tesla Model 3 have the highest A ++ rating, with Mercedes EQV MPV at the bottom of the list – the only car to earn the lowest E rating.

The most effective EVs revealed: With Tesla Model 3 earning the highest A ++ rating, a new e-rating system has been launched to let consumers know how economical the different power models are.

BMW's i4 saloon with a range of 365 miles has been given a new rating.

The website, which provides information and advice to electric car buyers and existing owners, states that the purpose of e-rating is to give customers a clear idea of ​​which EVs are best for their bank accounts.

While motorists understand the concept of miles per gallon for petrol and diesel motors, there is no industry-standard statistic to help drivers understand the overall efficiency of an electric car.

Since the public is well aware of energy labels in everything from washing machines to EPC scores, e-rating is a similar scale system to inform buyers of cars ahead of others.

The rating of each EV is calculated using an algorithm consisting of several factors.

The e-rating scale works like energy labels on everything from washing machines to EPC scores for properties.

The e-rating scale works like energy labels on everything from washing machines to EPC scores for properties.

It converts electrical power to how many miles on the road, including features that can help reduce power consumption, such as battery rechargeable speed and heat pumps, intelligent brake power recovery, and climate control prerequisites.

So far, the BMW i4 – with a range of £ 51,905 and 365 miles – and the Tesla Model 3 – priced from £ 42,990 and worth between 305 and 360 miles (depending on the spec) – has the highest A ++ ratings for EVs currently on sale in Britain.

Proving that this is not the only price, the £ 100,000 Mercedes EQS Luxury Salon Dinky and Cheap – Citroen Ami (approx £ 6,000) and Renault Twiji (approx £ 12,000 (approx £ 12,000, £ 0, 20 bicycles, 200 quattry, 000)) -In Car Grant) Mii Electric City Car.

These four vehicles are among 13 models to achieve A + ratings, and still perform well at 14 A’s.

E-ratings do not factor in vehicle prices, so the luxury Mercedes EQS Salon (left) – which starts at £ 100,000 in the UK – has the same A + rating as the Citroen Ami Quadricycle (right).

On the other end of the scale, the Mercedes EQV People Carrier – the only vehicle with a 213-mile range and the lowest E rating of £ 71,645, but the Audi e-tron (from £ 60,560) and Mercedes EQC (from £ 64,925) is rated D Have been made.

On the basis of miles per kilowatt hour, Electrifying.com has calculated a cost difference of £ 580 to cover 10,000 miles between the A ++ rated BMW i4 and the E-grade Mercedes EQV.

Although Mercedes People Carrier and BMW Family Salon are not competing in the same category, there are still huge differences between electric cars sitting in the same category.

For example, the Tesla Model Y (A + Rated) costs £ 176 less than the Volvo XC40 recharge, based on calculations.

Aside from the extra cost, owners may find that less efficient cars wait longer for a charge – in part they use more power to move, but they can also charge at a slower rate.

The Vauxhall Mokka Mazda can power up to twice the speed of the MX-30, for example, new Hyundai and Kia models can add up to 60 miles in five minutes.

With sales of EVs booming, the total number of electric vehicles on the road in the UK will top 300,000 before the end of 2021.

Taken nationally, the difference in costs between charging high and low-efficiency cars represents an estimated £ 155 million annually in electricity costs, says Electrifying.com.

The new efficiency rating was supported by AA President Edmund King.

Commenting on its arrival, he said: ‘Anything that helps customers determine the most effective EV in simple terms for their needs is a positive thing.

‘Before deciding on any type of vehicle, drivers must research a number of factors based on their individual needs and efficiency is an important factor for many.’

Ginny Buckley, founder of the EV-dedicated website, aims to tell consumers which rating models are more economical but also push manufacturers to improve.

‘It surprises me that electric cars do not have the same level of efficiency as we do in other sectors so far; But we’ve seen to put it right.

Since electricity is less expensive than petrol or diesel, it is easy to dismiss electric cars and feel that it is not important. But the costs of a less efficient model may soon add up.

‘Perhaps more importantly, an electric car with more economy going forward and less time charging means more convenience for customers.’
