We crunch the numbers connected the electrical cars connected merchantability contiguous to spot which travel closest to hitting their advertised figures
Plenty of electrical cars person awesome claimed scope figures but managing to execute them is different story. With the expanding fig of EVs to take from, buyers are hunting for the astir energy-efficient electrical cars to truly marque the astir of their batteries betwixt charges.
Electric car ratio is measured by calculating its miles per kilowatt hr used, shortened to mpkWh. For example, a Volkswagen ID 3 with a 77kWh artillery would necessitate an ratio of 4.5mpkWh to execute its officially rated 347 miles of range.
A vehicle's ratio is affected successful respective antithetic ways, with aspects specified arsenic value proving to beryllium a cardinal origin successful positively oregon negatively impacting range.
The Audi Q8 E-tron, for example, is powered by a 106kWh battery, but weighs a staggering 2585kg, meaning it tin present lone astir 2.9mpkWh.
Larger, SUV-style electrical cars are besides usually impacted much by drag, which reduces their scope compared with sleeker, much aerodynamic sports cars and hatchbacks.
The scope and ratio of electrical cars are besides heavy influenced by the upwind conditions and extracurricular temperatures. Warmer temperatures mean a battery’s chemic reactions tin hap faster and connection higher range, whereas colder upwind requires much energy, reducing range.
Other aspects dictated by the driver, specified arsenic however accelerated you thrust and the usage of clime power oregon aerial conditioning, besides impact range. A car volition often beryllium capable to question further connected a azygous complaint successful the metropolis compared with connected the motorway, arsenic much powerfulness is required to prolong higher speeds and grip the increase in drag.
Now you cognize however an electrical car’s ratio is impacted - but just however businesslike are electrical cars successful the existent world, and which are the astir businesslike electrical cars connected merchantability today? Our database beneath details the champion EVs to compression the astir mileage retired of your battery.

Volkswagen ID 3
Claimed efficiency 4.5mpkWh
Autocar’s trial efficiency 3.8mpkWh
Having entered its 2nd procreation successful 2023, the Volkswagen ID 3 has proved itself to beryllium 1 of the astir businesslike electrical cars connected sale.
Volkswagen’s first-ever bespoke electrical hatchback, which launched backmost successful 2019, is present disposable with some a 58kWh artillery and a 77kWh unit. With that larger battery, Volkswagen says the ID 3 is capable to question 347 miles connected a azygous charge.
In our tests, the ID 3 matched the Kia Niro EV, signaling 3.8mpkWh. That calculates to 292 miles of scope successful the existent world, which places the ID 3 adjacent the apical of the database of the astir businesslike electrical car connected sale.

Kia Niro EV
Claimed efficiency 3.9mpkWh
Autocar’s trial efficiency 3.8mpkWh
The fashionable Kia e-Niro was renamed this twelvemonth with the motorboat of its boldly styled second-generation model. Now called the Kia Niro EV, it inactive packs the aforesaid versatile powertrain set-up arsenic the erstwhile car.
It combines a 67kWh artillery (64.8kWh usable capacity) with a 201bhp electrical centrifugal and has a claimed 285 miles of range. There is 1 downside: the Niro EV inactive falls down its competitors successful presumption of charging speeds, with a maximum of 72kW.
But that mightiness not matter, fixed the Niro EV’s awesome vigor efficiency, which makes it 1 of the astir businesslike electrical cars disposable successful the UK. It's claimed to be 3.9mpkWh and our tests returned 3.8mpkWh - astir precisely arsenic advertised. That equals 246 miles of range.
Vauxhall Corsa-e
Claimed efficiency 4.4mpkWh
Autocar’s trial efficiency 3.7mpkWh
The Vauxhall Corsa-e launched successful 2021 with a 50kWh artillery and 222 miles of range. Vauxhall doesn’t explicitly punctuation its mpkWh figures, but utilizing that authoritative 222 miles scope fig and the size of the artillery produces a fig of 4.4mpkWh.
Our trial gave 3.7mpkWh, which calculates to astir 185 miles of range. Similarly to the electrical Fiat 500, the Corsa-e weighs astir 1455kg, which helps the hatchback execute its awesome ratio score.
Keep an oculus out, though, arsenic Vauxhall is acceptable to motorboat a revised mentation of the Corsa-e with artillery updates that boost its scope to 246 miles. In theory, that takes the Corsa-e’s ratio up to astir 4.8mpkWh.
