BACKGROUND

Lexus is best known for hybrids rather than for battery electric cars, but it launched the UX 300e in the UK in 2021, however this EV only had a 54 kWh battery and an electric driving range of 196 miles, which was less than most competitors. Lexus has now fitted a 72.8 kWh battery to the UX 300e and it offers a more practical 273-mile electric driving range.

DESIGN & ENGINEERING

The compact UX is the smallest Lexus SUV, measuring 4,495mm in length, with a boot capacity of 367 litres. In comparison, the other electric SUV from Lexus is the larger RZ, which is 4,805mm long, with a boot size of 522-580 litres. The cabin design and materials will be familiar to Lexus drivers. The exterior styling is a mix of angles and contours that will also be familiar to Lexus drivers…

The UX 300e now has a larger 72.8 kWh lithium-ion battery with the 204 bhp/300 Nm electric motor still driving the front wheels.

LEXUS UX 300E DRIVING EXPERIENCE

Lexus sets out it stall around the refinement of its cars, and electric powertrains make cars even more refined, so the UX 300e feels super-refined. Ride quality is also good, resulting in a comfortable driving experience.

And the UX 300e feels relatively light with agile handling – as it should for a compact SUV, although it actually weighs 1,785 kg, which isn’t particularly light, but it is lighter than most EVs. And performance is good, with a 0-62 mph acceleration time of 7.5 seconds. So the overall driving experience is good, however the UX 300e is front-wheel drive, so if you’re accelerating out of a junction onto a busy main road in cold and wet conditions, lots of wheelspin can result.

However despite the lack of all-wheel drive, during its week on test the Lexus managed to successfully negotiate numerous roads in the Lake District that were flooded with more than a foot of water – so proving that electric cars do indeed work in water.

The UX 300e has three drive modes – Sport, Normal and Eco – which are accessed by twisting a dial on the left-hand side of the driver’s instrument display. A similar control on the right-hand side of the instrument display allows you to disengage the traction control.

There’s a wide central touchscreen, with helpful shortcuts including navigation, media and phone on the right-hand side of the screen, but the graphics and user interface aren’t as sophisticated as those from many rivals. A separate strip of heating and ventilation controls sit under the main touchscreen, which work well.

The UX 300e has a traditional gear selector, which is becoming increasingly rare in new EVs, and there are steering wheel-mounted paddles to change the level of regenerative braking.

The 2023 Lexus UX 300e still has no towing rating.

LEXUS UX 300E ELECTRIC RANGE AND CHARGING

The 2023 Lexus UX 300e has a WLTP combined electric driving range of 273 miles, which is a useful improvement over the 196-mile range of the previous model. And our test car even matched the 273-mile range in the real-world – if you switched off the heating. With the heating on, the average range was 243 miles.

One important point to note about the UX 300e is that unlike virtually all EVs on sale today, apart from the Nissan LEAF, it has a CHAdeMO rather than a CCS DC charging socket, which is located on the passenger side rear wing, with the Type 2 socket on the driver’s side rear wing. Also, the UX 300e’s maximum DC charging rate is 35 kW – which is very slow; in fact it takes 1 hour 20 minutes for a 0% to 80% charge. A 0% to 100% charge at a 7kW wallbox takes 9 hours 30 minutes.

Electric cars do not charge at their maximum charge rate for an entire charging session – their charge rate typically starts off high with a battery with a low state of charge, then the charge rate decreases as the battery charge increases. See the charge curve for the Lexus UX 300e from Fastned:

PRICE AND MODEL RANGE

The Lexus UX 300e Takumi costs £57,095. Our test car had the option of ‘Sonic Grey special metallic paint’ (£920). The trim choices are the 300e from £48,625, the Premium Plus Pack from £50,995, and the Takumi Pack from £57,095.

The Takumi Pack includes heated seats and heated steering wheel which are really helpful to reduce cabin heating in cold weather and therefore conserve the battery and maximise range.

Conclusion

The Lexus UX 300e is very refined to drive with comfortable ride quality, relatively agile handling and good performance – although using the performance on wet roads can result in wheelspin thanks to its front-wheel drive chassis. The bigger battery with its longer range is great news, but CHAdeMO DC charging is a rarity on new cars, and a maximum DC charging rate of 35 kW is much slower than all rivals. Along with the car’s compact size and its infotainment system that isn’t as slick as most rivals, it makes our test car’s £57,095 price look very expensive. The Lexus UX 300e is awarded a Green Car Guide rating of 7 out of 10.
