Lexus UX (2019-present): dimensions and boot space

The Lexus UX is a family SUV available with either a hybrid petrol-electric setup or in electric form, with these known as '250h' and '300e' models respectively. It’s an upmarket choice, aimed at drivers who might also be considering a BMW X1, Mercedes GLA or a Volvo XC40.

There are also electric rivals for the 300e version, including the Kia EV6 and Volkswagen ID.4. You can read more about the UX in our UX buying guide and review - it’s an excellent car for those looking for a reliable and good-to-drive SUV.

The UX is a little on the expensive side, and there could be more room inside - as we’ll see below - but the UX is one of Lexus’ most impressive models at the moment. It’s very well made, drives very well on bumpy British roads and has lots of equipment available.

This article looks at the dimensions of the car as well as crucial other statistics that will help you to work out if the car is right for you. We’ll cover the two- and four-wheel-drive versions of the 250h, as well as the 300e fully-electric version.

Read on to find out more about the Lexus UX’s dimensions, boot space and weight.


Lexus UX dimensions

The Lexus UX is the same size no matter which version you choose. It’s 4,495mm long, 1,840mm wide (with the mirrors folded) and 1,540mm tall. The 300e model is 5mm taller officially, though that’s such a small difference that it’s practically the same.

This means that the UX is about the same size as a BMW X1 or Volvo XC40. The BMW is 4.4m long, 1.8m wide and 1.6m tall, while the Volvo is 4.4m long, 1.9m wide and 1.7m tall.

Interior space is okay in the Lexus, but nothing special. The Volvo XC40 in particular is roomier for rear-seat passengers than the UX, although legroom and headroom is fine for kids - so the UX still works as a family car. The small windows mean that not a lot of light gets in, so it does feel a little gloomy in the back.

Lexus UX boot space

Boot space in the Lexus UX is different depending on which model you choose. The normal 250h model, which uses a petrol engine and an electric motor driving the front wheels only, has 320 litres of boot space, which is a low amount for a car of this type. If you choose the four-wheel-drive 'E-Four' model, this goes down to a poor figure of 283 litres.

However, if you go for the 300e electric version, there’s actually more space: 367 litres. With the rear seats folded down, there are 1,231 litres and 1,194 litres in the UX and UX E-Four respectively, but Lexus doesn’t provide a figure for the 300e.

Unfortunately, all of these figures are poor for a family SUV. The BMW X1 and Volvo XC40 both have around 450 litres of boot space with the rear seats up, and the BMW has up to 1,550 litres available with the rear seats folded down.

Lexus UX towing capacity

The Lexus UX is a poor option if you want a tow car, because even the four-wheel-drive E-Four model is limited to a maximum trailer weight of just 750kg. Even worse, the electric 300e isn’t rated for towing at all, so you cannot legally tow a trailer with this car.

Lexus UX weight

Weight is a crucial factor in any car because it affects things like roadholding, performance, fuel economy and comfort to a large degree. The Lexus UX is an electrified car, so it carries batteries around with it at all times, and these are rather heavy.

The kerb weight allows us a comparable figure with other similar models, and it’s clear that the UX is a heavy car considering its size. The 300e model, in particular, weighs more than 1,800kg, which is around 50% more than many normal family cars.

We can see in the table below that the E-Four model, which has four-wheel-drive, is heavier than the normal UX. This explains why it’s a little less efficient.

Lexus UX Electric1,785kg - 1,840kg
