What Car? says...
The BMW X4 M Competition is a coupé-inspired take on the boxier and slightly cheaper X3 M Competition.
Both cars sit right at the top of their respective ranges and pack more than 500bhp, have extra body bracing to help them stay more upright and stable through corners, and get bigger brakes designed to cope even with race track abuse.
A 500bhp SUV might sounds pretty bonkers, but it’s far from a novel concept these days. Indeed, the X4 M Competition competes against the similarly power-crazed Mercedes-AMG GLC 63S Coupé and Alfa Romeo Stelvio Quadrifoglio, as well as the Porsche Macan Turbo.
Indeed, BMW reckons the X4 M Competition should feel more like a sporty saloon than a hefty SUV, and to help achieve that it actually borrows its four-wheel drive system from the M5 saloon, with a limited-slip differential that boosts traction on the way out of corners.
Has all this worked, though? Have BMW’s M division engineers managed to avoid the usual sports SUV pitfalls, such as an overly firm ride and unrewarding handling? Over the next few pages, you’ll find the answer to all these questions and more.
