A HIGH performance model inspired by Infiniti's collaboration with F1 world champions Red Bull Racing will make its world premiere at the Detroit Motor Show this month.

The Q50 Eau Rouge, a design concept based on Infiniti's Q50 sports saloon, is named after a famous section of the Spa racing circuit in Belgium.

Infiniti says the concept's major bodywork components have been redesigned with aerodynamics in mind and only the roof and door profiles remain unchanged from the production Q50.

Lower and wider, the Eau Rouge also features a deep carbon fibre front splitter, rear diffuser and side sill skirts along with 21-inch forged alloy wheels and a dual-exit sports exhaust system below a large rear spoiler.

Design chief Alfonso Albaisa said: "From our shared passion for performance with Infiniti Red Bull Racing grew a collective desire to produce a vision of what a high-performance Infiniti Q50 could look like.

"The design has a number of distinctive Formula One inspired touches.  In particular, the sculpted front wing assembly and the rear aerodynamic packaging take their cues from the RB9 race car."

Meanwhile, Kia's GT4 Stinger concept car is also set to make its debut at the Detroit extravaganza.

Designed in California, the GT4 Stinger sports the latest version of Kia's signature Tiger Nose grille, resting just inches from the ground.

The surround glows white and is flanked by vertical LED headlamps.  Front-brake cooling vents funnel air around 20-inch wheels while a carbon fibre front splitter mounted below the bumper provides added downforce.

Power comes via a 2.0-litre turbocharged engine delivering 315bhp to the rear wheels.

And Nissan, is showing its Sport Sedan Concept, which will be joined at the show by the North America debuts of the Nissan IDx Freeflow and IDx NISMO concepts.

The Sport Sedan Concept previews a new design direction that continues Nissan's approach of applying sports car principles to a saloon car.

And the IDx Freeflow and IDx NISMO's offer two different approaches to a next-generation compact vehicle - one expressing a lifestyle-focused vision and the other a sporty design that looks as if it came from a driving video game.
