Like other M37 variants, the M37X has a mode selector switch to allow operation in Sport, Standard, Eco and Snow modes, which alter the transmission and throttle mapping to match the driver’s desire for either performance, economy, or a compromise between the two (the snow mode is an occasional-use mode that dulls throttle response to avoid spinning tires in the snow).

In Eco mode the car gives visual and tactile reminders to go easy on the throttle, with the “Eco” dashboard light first changing from solid green to flashing green, and then changing to yellow, and the Eco Pedal pushing insistently back against you (though it can be easily overridden with a little extra force). In practice the Eco Pedal is a bit like having your spouse kicking you under the table to remind you not to be rude to your aunt Petunia during Thanksgiving dinner: it’s probably helpful, but also slightly annoying. Thankfully, unlike your spouse’s insistent kicking the Eco Pedal’s tactile reminder can be easily shut off by switching to standard mode.

What was surprising to me was just how early the eco warnings kicked in: I found it pretty much impossible to keep up with regular city traffic flow without getting chided for my heavy-footedness. So after playing with the Eco mode for a brief while I switched over to Sport mode and gave free rein to the horses, with the result that I managed to burn through 15 litres of fuel in a little over 100 km of mixed city and highway driving (official city/highway fuel consumption ratings for the M37x Sport are 12.0 / 8.3 L/100 km). In fairness, my driving was in cold weather and included a spirited run up (and then back down) a steep, switchbacked ski resort access road.

Speaking of ski resorts, I was able to get three pairs of skis into the M37x Sport thanks to the trunk pass-through, but I wouldn’t have wanted to try cramming a fourth pair in there, because the pass-through is fairly small. And if you have snowboarders amongst your friends or family you’ll need to invest in a roof rack because the rear seatback doesn’t fold.

Price-wise, my M37x Sport test car showed a suggested sticker of $69,395 including destination charges and a $300 three-coat paint option. At this price it competes against the likes of BMW’s 535i xDrive (which starts at $66,895 including destination), Cadillac’s CTS (which starts at $62,635 when similarly equipped with all-wheel drive and the Performance Collection 1SH package) and the Acura RL ($66,635 destination in). With its appealing style, athletic performance and finely crafted, well-featured interior, the big Infiniti certainly deserves its share of attention.
