TOP 5 Most fuel efficient

1TESLA MODEL X

0.0L/100km Up to seven seats and swanky rear ‘falcon wing’ doors make for one snazzy machine.

Fast, too, in P100D guise and with up to 542km of claimed all-electric range.

2TESLA MODEL S

0.0L/100km Same philosophy as the X but with a luxury liftback body. Floor-mounted batteries and low stance keep the centre of gravity low. The same motors as the X with less weight equals more fun.

3NISSAN LEAF

0.0L/100km It’s a slow seller (less than one a week) and has a design only Noddy could love. But the Leaf offers mainstream hatchback performance with a specialty in low-speed electric motor flexibility.

4BMW i3

0.0L/100km More batteries makes for a longer range in the all-electric i3 94Ah, which will do about 200km in normal driving. Those wanting to go further can choose the range extender instead, which is claimed to use 0.6L/100km.

AUDI A3 e-tron

1.6L/100km The most efficient of the plug-in hybrids on the market (at least according to the official fuel figures), the e-tron is refreshingly normal to look at and drive, with a 1.4 turbo allied to an electric motor.
