MPG, running costs & CO2 Rating

4.5 out of 5

The Lexus UX 300h uses the very latest hybrid technology that Toyota has to offer, having much in common with the latest Toyota Prius.

Lexus UX MPG & CO2

Official WLTP figures span from 54.3 to 56.4mpg for the standard UX 300h and 49.5 to 50.4mpg for the ‘E-Four’ four-wheel drive version. Those figures represent an improvement of around 5mpg over the now-discontinued UX 250h, but in reality we managed nearly 60mpg during our in-depth test, despite the big 18-inch alloy wheels included with the F-Sport trim level.

Stick with two-wheel drive and the Lexus UX emits from 113/km of CO2 with 17-inch wheels fitted to 119g/km with 18-inch alloys. Benefit-in-Kind (BiK) liability for company-car drivers spans from 27 to 28%. Emitting around 126-129g/km, the four-wheel drive UX sits in a higher BiK band with either size wheels.

Insurance

The Association of British Insurers has placed the Lexus UX in insurance groups 22 out of 50, which is identical to the cheaper but mechanically related Toyota C-HR hybrid in Excel form. Meanwhile, the most economical Mercedes GLA is in insurance group 29, while the BMW X1 starts in insurance group 24.

Servicing

Lexus offers fixed-price servicing for all models. Although pricing for the UX has yet to be announced, service schedules are sure to match the pattern of other hybrid models in the range, with a major service every 20,000 miles and an intermediate oil-change service every 10,000 miles.

Warranty

Lexus' three-year/60,000 mile warranty closely matches that provided by Volkswagen and Audi, but falls behind the three-year/unlimited-mileage warranties of Mercedes and BMW. Yet like parent firm Toyota, you can extend cover up to 10 years or 100,000 miles, provided you continue to have the car serviced at an authorised dealer over the same period. Lexus can provide an extended warranty, though, keeping you covered once your original policy's age or mileage limit is breached. It's also worth noting that the hybrid powertrain comes with a five-year/60,000 mile warranty for extra peace of mind.
