PRICE Up by $3000 on base model 20i thanks to extra kit and tops out at $109,900 for the M40i
TECHNOLOGY A head-up display is now standard across the range. Active safety suite now includes traffic sign recognition.
PERFORMANCE The mid-spec diesel has been dropped, leaving the 30i petrol with marginally more power but less torque than the 35i it replaces. The M40i is then seriously quick.
DRIVING As with its predecessor, the ride is a touch too firm around town but this one handles a touch better.
DESIGN Bigger in every dimension but height, the X4 now has the volume to go with its voluptuous looks.
