Lexus UX MPG & CO2

The Lexus UX 250h uses the very latest hybrid technology that Toyota has to offer, having much in common with the latest Toyota Prius. Official WLTP figures span from 50.4 to 53.2mpg for the standard UX and 47mpg for the four-wheel drive version. We managed 50mpg in a test car, 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 120g/km of CO2 with 17-inch wheels fitted and 126g/km with 18-inch alloys. Benefit-in-Kind (BiK) liability for company-car drivers spans from 27 to 28%. Emitting around 135g/km, the four-wheel drive UX sits in a higher BiK band with either size wheels.


The Association of British Insurers has placed the Lexus UX in insurance groups 22 to 26 out of 50, making the Lexus a little more expensive to insure than the cheaper but mechanically related Toyota C-HR hybrid, which occupies insurance group 14 in top-spec Excel form. Meanwhile, the most economical Mercedes GLA is in insurance group 21, while the BMW X1 starts in insurance group 26.


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.


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. It also lags behind that provided by Toyota, which lasts for five years or 100,000 miles. 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.
