The muscular hood, which has beefy sides that inspire you as you drive, hides (in the case of our test car)... an engine shared with the Nissan Navara.
We’’re not saying the M30d comes with a powerplant borrowed from a pick-up truck, but the unit doesn'’t manage to be 100 percent lively enough for the badge.
As you probably know, Infiniti didn’’t want to meet Rudolph until last year, when the company borrowed the Renault-Nissan Alliance’’s 3.0-liter V6 diesel unit. The V9X engine delivers 238 hp at 3,750 rpm and a maximum torque of 550 Nm (410 lb-ft).
On paper, the engine should offer satisfying straight-line performance, but it doesn’’t feel like it. The seven-speed torque converter automatic is not the problem, as it does a decent job, but the 1,845 kg (4067 lbs) of the car just need more muscle in order to bring good sensations to the game.
Actually, this is where the problem lies. You see, Infiniti used aluminum for the hood, doors and boot lid, but you could swear that someone has come and replaced those panels with a set borrowed from a stone age car. Why? Because the scales are burdened with one hundred and a few tens of kilograms more than in competition’’s case.
So, the oil burner doesn’’t match Infiniti’s sporty ambitions, but what about the luxury-related ones? Fortunately, the mill shines from this point of view, relying on a low idle speed and special mounts to offer a low NVH level.
Infiniti offers the driver a special whip for controlling the engine and the transmission, in the form of the Infiniti Drive knob, which plays with the throttle sensitivity and gearbox mapping. This offers four modes: Standard (boring), Eco (a true nature’’s friend), Sport (the only one that manages to bring the car closer to what it’s design promises) and Snow (useless if you know how to use your right foot).
All in all, the M30d offers a decent tech package, but it doesn’’t manage to bring anything that would make your jump for joy to the game. We’re sure things would have been dramatically changed if we had dealt with the 3.7-liter petrol V6 mill that powered the G37 sedan we previously tested.Continue reading
