Since we road tested the Model S, the benefit-in-kind tax liability on zero-emissions cars has been almost doubled by the UK government.

Buy a Model X today and run it as a company car and you’ll pay tax on nine percent of its showroom price. That’s the same as the owner of a Volvo XC90 T8 plug-in hybrid or an Audi Q7 e-tron would pay, although it’s still a quarter of the tax penalty incurred by a conventionally powered Range Rover Sport.

Our experts predict the Model X will shed almost £20k more than the Range Rover over three years

Even electric cars don’t escape the new ‘premium rate’ road tax bracket that is due to be imposed in April. It will take a year’s VED on any Model S or X from free to £310 (although it’ll revert to free again once your car is five years old).

The Model X takes about an hour to charge from almost flat to almost full when connected to one of Tesla’s ‘supercharger’ DC fast-chargers, of which there are now more than 30 in the UK, and via which Tesla will give you 400kWh of free power (between five and eight typical charges) per year.

After that, electricity is chargeable at 20p per kWh, so a full charge costs less than £20. A full at-home charge of a Model X 90D or P100D would likely take in excess of 12 hours, or longer still on a three-pin domestic plug, and cost about £10 at typical UK electricity rates.

As far as electric range is concerned, our test car indicated that it would cruise at typical UK motorway speeds while consuming power at just under 500Wh/mile, making for a real-world range of just over 180 miles.

Expect a P100D to just tip over the 200-mile threshold and a 75D to make 150 miles or so. That’s workable for some, perhaps, but not quite as convincing as the Model S was.
