Will an electric car maintain its quoted range if it's driven at high speeds?

How do quoted economy figures for battery-electric cars hold up if the car is driven continuously at motorway speeds? My daughter lives 170 miles away and all but 2 miles is on a dual carriageway or motorway.

Not great. Electric cars are at their best driven around town – at low speeds, with lots of regenerative braking capturing energy and giving the remaining range a boost. In our experience, electric vehicles start to lose range quite rapidly above 60mph. A longer-range electric car like the Volkswagen ID.3 Tour or Tesla Model 3 Long Range should be able to do that journey quite comfortably, though.

Superb introduction to electric cars. Easy and relaxing to drive (but also fun). Priciest models can travel 336 miles between charges.
Spacious, minimalist interior. Relatively affordable. Range of up to 348 miles. Fun to drive.
