Buying Tips for the 2021 BMW i4 (G26)

✓Test the curved iDrive display for lag or freezing, and ensure the latest OTA software updates have been applied.
✓Verify the real-world range; the M50 model is incredibly fast but sacrifices significant range compared to the more sensible eDrive40.
✓Inspect the charging port to ensure the locking pin works correctly; a jammed pin will prevent the car from releasing the charging cable.
✓Check the condition of the rear tyres, as the massive instant torque (especially on the M50) wears them out very quickly.
✓Listen for any knocking from the rear air suspension (standard on the i4 to handle the battery weight) over speed bumps.
✓Ensure the artificial 'IconicSounds' generator works correctly when accelerating in Sport mode, though it can be turned off in the menus.
