2015 Bmw X4 Xdrive35i

2016 Bmw 340i

2017 BMW X4 M40i basically a hatchback version of the X3, the X4 is a four-door “coupe,” with a low roof and a more intimate cabin—especially in the back seat. Engine choices are a 240-hp turbo four, a 300-hp turbo six, and for the Xtra-est of Xs, there is the M40i with 355 hp, launch control, bigger front brake discs, 19-inch wheels, and a sport-tuned suspension. All X4s have an eight-speed automatic transmission and torque-vectoring all-wheel drive. Driving dynamics are excellent; these are BMWs, after all.
