First shown at the Detroit Motor Show in January, the Infiniti Q50 will be displayed with four-cylinder engines at Geneva, as the firm bids to increase the appeal of its BMW 3 Series and Audi A4 rival in Europe.
In the US, the Q50 will be offered with two powertrains; a 323bhp 3.7-litre petrol V6 and a 355bhp 3.5-litre petrol V6-electric hybrid, with the choice of rear or four-wheel drive.
However, European buyers will benefit from Infiniti and parent company Nissan’s tie-up with Mercedes, who is expected to provide its 1.8-litre petrol engine and 2.1-litre four-cylinder diesel.
The Q50 replaces the Infiniti G Series saloon and features a curvaceous 'double arch' grille and an inverted crescent-shaped kink in the C-pillar.
On the inside, Infiniti promises much improved head and legroom for all passengers, while active noise cancellation, via the Bose sound system, comes as standard.
Of most interest is that the Q50 will be the first car to feature Nissan’s new Direct Adaptive Steering technology.
The system is a world first and does without the mechanical link between the steering wheel and the front wheels. Instead, it uses a fly-by-wire system where inputs to the wheel are fed electronically to a motor which moves the steering rack accordingly.
The driver can adjust the feel and weight of the steering to their personal tastes, and the system also includes an auto-steering lane keeping assist function.
Should the electronic system fail there is a back up steering column, which uses a clutch to reconnect the steering column and wheel. The current system is a legal requirement for the time being, but Nissan is hopeful that this rule can be changed in the long term.
The Infiniti Q50 is due to go on sale in the UK in June. It will be shown at Geneva alongside the all-electric Infiniti LE concept car, and Sebastian Vettel’s 2013 Formula One car complete with the 2013 livery, which features more prominent Infiniti branding.
