Infiniti QX70 (FX)
Formerly known as the FX, the Infiniti QX70 is a striking, aggressive-looking luxury SUV that prioritized sporty handling and swooping design over outright practicality. It drove more like a tall sports car than a traditional SUV, offering a firm ride and potent V6 engines, including a raucous 3.7-litre petrol and a muscular 3.0-litre diesel. In the UK, its bold styling and massive 21-inch wheels gave it immense road presence, though its heavy fuel consumption limited its appeal. Reliability is excellent, underpinned by proven Nissan mechanicals. It is best suited for buyers who want an imposing, sporty, and reliable SUV, and are willing to accept high running costs and a relatively small boot.
