The new Lexus LS has only just been introduced earlier this year, but already Toyota’s luxury offshoot is looking to the future with the LS+ Concept. Making its world premiere at the 2017 Tokyo Motor Show, the show car previews a range of automated driving features set to be introduced on its flagship sedan in 2020.

Although the basic shape of the LS has been retained, the concept features an even more aggressive front fascia, dominated by the triangular laser-powered headlights. The spindle grille has also been significantly redesigned and is fitted with a large grille shutter to improve cooling and aerodynamic performance, while a series of light guides frame the grille, highlighting its shape.

Moving back, there are cameras in place of door mirrors as well as flush door handles that add to the LS+’s futuristic look, while the tail lights feature an intricate three-dimensional look. Large, complex multi-spoke alloy wheels complete the look.

But those looks are only part of the story – the real reason why the LS+ exists is to highlight the technologies that will enable it to drive itself. The Highway Teammate system, previewed at the previous Tokyo show, takes complete care of driving – as the name suggests – on the highway, from entrance ramp to exit ramp.

Using appropriate recognition, judgement and operation by the onboard systems in response to actual traffic conditions, the system will allow the car to merge onto the highway, change lanes and exit automatically, as well as keeping itself in its lane and maintaining its distance to the car ahead.

The LS+ will also be able to perform software updates over the air, facilitating the addition of new features. The artificial intelligence on board, meanwhile, learns from big data, including information on roads and surrounding areas. This means that the car will be capable of a high-level of automated driving, and will also be able to learn and grow along with its user – strengthening the latter’s emotional bond to the car.
