Infiniti Q60Infiniti’s badly ageing Q60 coupe (née G37) has finally been replaced, with its shapely all-new successor debuting at the 2016 Detroit Motor Show.

Boasting Infiniti’s new-era design previewed by several earlier concepts, the new Q60 will provide a stern challenge to the BMW 4 Series Coupe, Mercedes-Benz C-Class Coupe and Audi A5 range whose owners it will need to win over.

Infiniti’s thus not messing about: it’s launched in 400hp 3.0-litre V6 twin-turbo guise, with the new VR30 engine claiming one of the best power-to-efficiency ratios in the class.

A rear-biased all-wheel drive system is promising, although the regular 208hp 2.0-litre four-cylinder turbo still drives the rear wheels instead of the less-driver-pleasing fronts; it can thank being based on the Infiniti Q50 for that.

That’s why it inherits the Q50’s rather disappointing interior, albeit lavished with latest gen connectivity, safety and infotainment tech.

Alongside the Q50-derived suspension of the standard Q60 is a new ‘Digital Dynamic Suspension’. Dampers are electronically adjustable and it’s backed up by the second generation of the drive-by-wire Direct Adaptive Steering system.

Trust us, says Infiniti, it’s better this time: feel and feedback are enhanced and “significant” changes make it more communicative (and hopefully less weird-feeling).

Infiniti is, like Lexus with its new LC 500, ambitious. “The Infiniti Q60 conveys a powerful elegance through its daring design, and has the performance credentials to match,” said Infiniti president.

“The Q60 will affirm Infiniti’s leadership in the premium sports coupe class.” Bold claim. The Q60 looks good: will the reality square up?
