“Electric cars are legendary for their acceleration and this summer Audi showcased a model that will go from 0 to 60 in two seconds. And yes, accelerating hard uses more power than if you drive more steadily. This is partly why there is a difference between the maximum claimed range you see in manufacturers' brochures and the 'real world' normal use figures we prefer to talk about on DrivingElectric.com. But it's not just because the engine naturally uses more power to maintain, say, 70 mph compared with 30 mph. Some tests have revealed that frequent hard acceleration does significantly waste power, compared with approaching your desired speed more gently. If you insist on flooring it every time you pull away, expect about 20% less range on a journey - just like any other car running on one tank of fuel.”
