2022 BMW I4 EDRIVE40 M Sport Electricity · MT72 BTF

As an electric vehicle, the i4 eDrive40 benefits from zero tailpipe emissions and exemption from Clean Air Zone charges in London, Birmingham, and elsewhere. VED (road tax) is currently free for EVs registered between 2017 and March 2025, though from April 2025 EVs pay the standard rate, and luxury-car supplement applies to vehicles over £40,000 new, which the eDrive40 M Sport almost certainly was. Insurance is likely to sit in group 38-40, so budget around £700-£1,100 per year depending on postcode and driver history. Real-world efficiency is typically 3.5-4.0 miles per kWh, giving a range of roughly 280-320 miles from the 84 kWh battery, and home charging at off-peak rates works out around 5-6p per mile. Tyres are the standout cost driver given the model's MOT failure pattern, with a full set of EV-rated tyres costing £600-£900.

The December 2025 MOT passed without recording any defects, which is positive but offers limited diagnostic depth. Inspect the tyres carefully: the i4 eDrive40 is heavy for its size and the instant torque can wear tyres quickly, particularly the rears. Look for uneven shoulder wear, which suggests alignment issues, and check the age of the tyres via the DOT stamp on the sidewall. EV-specific items worth checking include the charging port for damage or scorching, the 12V auxiliary battery (a common EV failure point not tested at MOT), and the brake discs, which can corrode due to regenerative braking doing most of the slowing. On the bodywork, check the front bumper and bonnet for stone chips, as EVs used on motorways accumulate these quickly.

Lift the car if possible and inspect the underside for any damage from speed humps, particularly the undertray and any exposed battery cooling lines. Check that all M Sport-specific trim pieces (side skirts, rear diffuser) are intact, as replacements are costly. Inside, verify the iDrive infotainment functions correctly, the digital key works, and there are no warning messages on the driver display. Finally, ask for a recent BMW diagnostic report or have a BMW specialist run one; the i4's high-voltage battery management system can flag cell imbalance issues that an MOT will never detect.
