Electric cars can achieve the equivalent of 350mpg – with resultant cost savings

For people who are still wondering if electric cars are cheaper to run than petrol cars, latest figures show that EVs can achieve the equivalent of 350mpg.

This compares to around 40mpg for a typical petrol car, with the current price of petrol at around £6.17 per gallon (£1.36 per litre). The same amount spent charging an EV on a smart energy tariff with an Ohme charger could see your car travel more than 350 miles.

Fully charging an Audi A6 Avant e-tron with a 75.8kWh battery from 0% with an Ohme smart charger on a dynamic tariff such as Intelligent Octopus Go could cost just £5.31 for its 361-mile WLTP claimed range.

By comparison, the same charge on the new Standard Variable Tariff (SVT) rate for electricity, which rose on 1 January 2026 to 27.69p/kWh, would cost £20.99 – almost four times more – but even at this rate this still represents a substantial saving compared to running a petrol car.

“The idea of a car doing 350mpg would obviously be fanciful, but that could be the reality when charging your EV on a smart energy tariff at home with Ohme,” said Ohme CEO David Watson. “Charging at home will always be the most affordable place for EV drivers to charge their cars even with this latest rise and changing to a smart electricity tariff will enable drivers to maximise those savings still further.”

Ohme is the official charger provider for Mercedes-Benz, Volvo Cars and the Volkswagen Group in the UK and Ireland as well as Genesis, Hyundai, Smart, Suzuki and XPeng in the UK. Ohme is also the official exclusive charger provider for customers on the Motability scheme, the largest fleet operator in the UK.
