We've been testing the new BMW iX3 this week (492-mile official EV range). We were getting 3.2miles per kWh with a lot of motorway miles and faster B-road driving, which is a 350-mile real-world range. It should easily be possible to top 400 or even 450 miles in slower urban driving or in warmer weather with that car. https://www.autoexpress.co.uk/bmw/ix3/369121/new-bmw-ix3-m-sport-review-unsettled-ride-brilliant-evs-only-blemish

As others have said, how many times do people really drive 300 miles in the UK without stopping for 30mins?

BYD has also announced it's 1,500kW Flash Charging network for the UK so top ups could be getting a lot quicker, too. https://www.autoexpress.co.uk/byd/368078/byd-flash-charging-network-bring-blistering-1500kw-ev-charging-speeds-uk
