The latest picture, which shows the concept in profile, follows last month’s release of a shot of the grille, and the announcement that the concept will offer ‘style and substance that push any pre-conceived limits’.

The four-passenger fastback concept, said to foreshadow an audacious top-of-the-line model, has been designed for a ‘low-slung, ingeniously aggressive’ look and intended to ‘demonstrate to the premium world just how Infiniti aims to play its part’.

The carmaker added: ‘A flashpoint for the company’s intuitive human-centric style and onboard technological ambition, the Q80 Inspiration long-leggedfastback proves that Infiniti intends to drive in and disturb the status quo.’

The announcement comes as Infiniti reveals its updated Q70 model, which goes on sale this winter featuring the 2.2-litre diesel from the Q50.

The concept makes its debut at Paris on the 2nd October.
