The QX70 moves faster than a two-tonne car has any right to. The 37 uses a 316bhp version of the 3.7 V6 from the Nissan 370Z, so it’s no surprise that it’s impressively brisk. The 50S has a 385bhp 5.0 V8, and performance is even more electrifying. Both are driven through a seven-speed automatic gearbox. Even the 30d's diesel engine shifts the car quickly and smoothly.
Infiniti QX70 4x4 ride & handling
The QX70 may not match the agility of a BMW X6 in the corners, but there’s fun to be had due to good body control and quick steering. The firm ride is a massive issue, though. You feel way too much of the surface at all speeds, and bigger bumps give your backside a serious jolt.
Infiniti QX70 4x4 refinement
The engines are quiet when you’re pootling along, and sound pleasantly meaty when you extend them, although the diesel isn't as refined as units from BMW and Porsche. Wind noise isn’t an issue, but with the massive tyres underneath you, you hear a lot of road noise - and even more if you go for one of the versions on 21-inch wheels. There's some clatter from the suspension, too.
