2017 BMW X4 Driving Impressions


For a vehicle of its size, the X4 behaves athletically. When breezing through a corner, body motions don’t become excessive, and little nosedive is evident.

Braking power is markedly less delightful, as the weight of the X4 becomes noticeable right away when attempting to slow down in a hurry. The M40i does better when quick braking is needed, thanks to upgraded front brake rotors that raise their ability to curtail forward motion.

Sport mode tends to be the most effective choice for most driving conditions, when the X4 is fitted with adjustable dampers, part of Dynamic Damper Control. The X4 driver can also select from Normal and Sport Plus modes. Making a choice affects steering feel, transmission shift points, and the feel of the gas pedal when starting off (throttle tip-in).
BMW’s xDrive system splits engine power 40/60 percent, front/rear. When alteration becomes necessary as traction conditions change, the system can transmit full power to the back wheels. However, the performance controller is able to divide torque between the two rear wheels, to improve overall stability and cornering capability. Unlike many all-wheel-drive systems, BMW’s xDrive is performance-focused, and not intended to make challenging off-road treks possible.

Fuel economy is similar to that of the X3. The BMW X4 xDrive28i is EPA-rated at 20/28 mpg City/Highway, or 23 mpg Combined. As expected, the six-cylinder X4 M40i is less frugal, EPA-rated at 19/26 mpg City/Highway, or 21 mpg Combined.
