Set to rival the Mercedes CLS, BMW 6 Series Gran Coupe and Audi A7, the concept five metres long and two metres wide but with a low-slung design that also features portal-style doors.

Inside there are four individual leather seats and a plunging panoramic glass roof. 

The concept also showcases autonomous driving technology as well as a high-performance and efficient hybrid-electric powertrain that is expected to deliver 550hp while returning 5.5L/100km. 

Infiniti also used the Paris Motor Show for the European premiere of the new 2015 Infiniti Q70. Powered by a new 2.2-litre, four-cylinder turbo diesel engine, it delivers 170PS of power and 400Nm of torque while retaining low carbon dioxide emissions, although figures were not given. 

The carmaker added that both models show the expansion of Infiniti’s upper range, providing strong indication that it is on track to increase its vehicle portfolio by 60% over the next five years, and to more than double the number of engines and transmissions.
