There are two engines to choose from, and neither is a slouch. With the 3.7-litre V6 engine, performance away from rest is in the sports car league: you'll dash past 62mph in a little over six seconds, and there’s loads of power in the mid-range, too. The diesel model isn’t quite as quick, but the 3.0-litre engine still shifts the QX50’s bulk smoothly and swiftly.
Infiniti QX50 4x4 ride & handling
In spite of the QX50's size, it feels nice and nimble. It doesn't have the tactile qualities of a sports car, but it's not bad for a 4x4. There's a limited amount of body lean through corners, but plenty of grip and a decent amount of feel, too. However, the payoff for this cornering ability is a rather lumpy ride at all speeds.

The petrol-engined QX50 provides the right sort of noise when you want it, but is pleasantly relaxed when you just want to cruise: there’s a small amount of wind noise, but not much engine- or tyre noise on the motorway. The diesel isn’t quite as impressive: the engine sends some vibrations through the driver’s seat at idle and is a little gruff until it’s warm, but on the move it’s hard to fault.
