BMW X3 M
The X3 M takes the practical G01 X3 body and injects it with the ferociously powerful S58 twin-turbo straight-six engine from the M3. Positioned as a seriously fast family SUV, it rivals the Alfa Romeo Stelvio Quadrifoglio and Porsche Macan Turbo. While it offers incredible performance, it is a heavy, stiffly sprung vehicle that burns through expensive tyres, brakes, and cooling components when driven hard. It suits speed-loving parents who need SUV practicality but refuse to compromise on outright acceleration and aggressive M-car dynamics.
