Redesigned in 2019, the X4 adds two variants to its lineup, the X4 M and X4 M Competition that boast 486 and 503 horsepower, respectively. These hot-rod SUVs provide the performance and handling of a true sports car. Otherwise, this SUV shares many mechanical components with the X3, but dressed in a coupe-like body. Inside, we get the brand’s modern iDrive infotainment system and a choice of trim options and equipment.
