Lexus will launch a new flagship model to sit above its existing range-topper, the LX. The new LF-1 Limitless concept on display at the Detroit motor show previews how it'll look.

The SUV has the footprint of a Range Rover but sits much lower. This suggests it could be a rival to the future Road Rover, due next year. It mixes familiar Lexus design traits like the large front grille that stretches to the car's lowest section, as well as new parts – including a full-length light bar at the back and smooth door panels.

Inside, the car places its infotainment system into a section of the dashboard and the instrument display is hexagonal in shape with a digital screen. Notwithstanding controls on the multi-function steering wheel, the cabin is free of buttons and switches and relies on digital technology for auxiliary control adjustments.

4D satellite navigation and haptic control technology are also in the spotlight, showing the advanced level of cabin infotainment Lexus intends to put into its future production models.

Lexus said the production car derived from the LF-1 concept could use fuel-cell, hybrid, plug-in hybrid, petrol or even all-electric powertrains, suggesting it would be built in several variants to cater to different global markets. The LF-1 has been labelled a crossover with a heavy road bias, as is evident from its low ride and profile.

The concept, designed by Lexus' California design team, is described as a flagship model, hinting that it would be an SUV coupé to sit above the range-topping LX – much like the positioning of the Audi Q8 in comparison with the Q7.
