From a Dezeen.com online review:

On a single charge, Helia can cover a range of 900 kilometres – the distance from London to Edinburgh. Again, compared to the Tesla 3, the Cambridge University team’s car has double the range on a battery a quarter of the size.

The ability to cover this distance is aided by Helia’s chassis and body panels made from carbon fibre, which grant it a kerb weight of 550 kilograms.

Students from Cambridge University have built an ultra-efficient electric car that drives using only as much power as it takes to boil a kettle.

The Cambridge University Eco Racing (CUER) student society built the four-seater car, named Helia, with efficiency as the main goal.

Their achievement has been to produce a car that can travel 80 kilometres-per-hour using only 2500 watts, or as much power as it takes to boil a single kettle, which is equivalent to 31 watt-hours-per-kilometre.
