Lexus claims that those choosing the UX 300e over a diesel-powered rival (it lists those from Mercedes, Jaguar, Volvo, Audi and BMW) will save £3,000 in fuel over four years. That's a big claim and one that should attract the attention of plenty of prospective customers. And while an electric SUV can't quite match a diesel equivalent for outright range and road-tripping ability, the UX 300e will certainly be an easy switch for those whose motoring takes place regularly and over shorter distances.

It's quite expensive to buy outright for private owners when compared to internal-combustion rivals, but we'll have to see what monthly PCP payments look like – if you take into account fuel savings, fewer moving parts and exemption from the London Congestion Charge and similar schemes, the UX could well be worth the outlay. 

It goes without saying that company-car users will welcome the UX 300e's non-existent local CO2 emissions, which equate to a 0% BiK rate and therefore no tax payable. This will go up to 1% in the 2021/22 tax year, but that's still much better than any petrol, diesel or hybrid-powered car.

Lexus UX 300e insurance group

There's no insurance-group information available at time of writing for the UX 300e, but by taking a look at its hybrid siblings – which generally sit in groups 22, 23 and 26 depending on specification – we can guesstimate that the pure-electric version will be slightly more expensive to insure, perhaps occupying group 30.


The UX is covered by a three-year/60,000-mile warranty, while its battery is covered for eight years or 100,000 miles. The first of these is not the most competitive on the market – Kia's 100,000-mile/seven-year warranty is still the one to beat – but coverage should be enough for the average three-year lease regardless.


Exact servicing information isn't available yet for the UX 300e, but the brand is famed for its customer service and has plans available to help spread the cost of maintenance; these Lexus Service Plans let you choose both plan length and payment frequency, as well as which services to include. Standalone servicing prices start at £225 for Lexus models of all ages. 

Road tax

You won't have to pay any VED (road tax) in the UK on account of the Lexus UX 300e's status as a zero-emissions 'alternative-fuel vehicle'.
