The Q50 is based on a widely enhanced version of Nissan’s ‘FM’ platform. It’s built predominantly out of high-strength steel, with aluminium parts adding lightness. It permits a longways engine, front-mounted transmission and rear-wheel drive, and features double wishbones at the front and multi-link suspension at the rear.
The Infiniti’s curvy styling is likely to be a decisive factor for those who take the plunge. It makes the Q50 stand out among its straight-edged German business saloon rivals rather effectively and was widely approved of by our test team. If the primary job of that styling is to win admiring glances from those who simply haven’t considered an Infiniti at all, the designers can celebrate a victory.
But the Q50 must be about substance as well as style if it’s going to make a difference in sales terms. And making the biggest difference on that front is a 2.1-litre, four-cylinder common-rail turbodiesel engine derived from the one found in a Mercedes-Benz C 220 d but modified in key areas.
The changes made to it by Infiniti’s engineers were, it says, intended “to ensure engine response is in line with Infiniti’s emphasis on performance”.
