Lexus has unveiled the new RX, its contender in the premium SUV segment.

The fifth-generation model is available with three hybrid engines, including one plug-in hybrid.

Together with the recently launched NX and newly revealed RZ electric SUV, the RX is said to represent the ‘Next Chapter’ of the Lexus brand.

It’s based on Lexus’s GA-K platform, similar to that which underpins the new NX, but with a different set-up. The rear has been redesigned to extend the wheelbase and increase rigidity.

The new platform has enabled a 90Kg reduction in the car’s weight and a lowering of its overall height by 10mm, contributing to a 15mm lower centre of gravity. The wheelbase is longer by 60mm within in an unchanged overall length.

The line-up kicks off with the RX 350h. It uses a 2.5-litre hybrid petrol engine that develops 245PS and emits 143-150g/km of CO2.

The RX 450h+ is a plug-in hybrid, utilising the 350h’s engine, but adding a second electric motor and an 18.1kWh battery. Power is boosted to 306PS, while CO2 emissions are 24-26g/km. A zero-emissions range of 40 miles is expected.

At the top of the range, the RX 500h uses a new 2.4-litre turbocharged petrol engine, with a twin motor hybrid system. It produces 371PS and emits 182-189g/km.

The RX Is equipped with a 14-inch multimedia touchscreen, which forms part of its driver-centric cabin. Interior space has been boosted, thanks to the longer wheelbase and Lexus said the car benefits from re-designed seats that can also be trimmed in a synthetic leather.

Prices are yet to be announced. The new RX is likely to arrive in early 2023.
