2015 BMW I8 1.5L Hybrid electric (clean) · E8 PSE

The most recent MOT on 22 May 2026 was passed, with the sole advisory noting slight damage or perishing of the near‑side rear tyre’s inner edge. All preceding tests from 2022 through 2025 also resulted in passes with no recorded defects, indicating a consistently stable maintenance record with no emerging failures or deteriorating components evident from the MOT data. At 77 312 miles the i8 has averaged roughly 7 000 miles per year since its 2015 registration, a usage rate that sits comfortably within the normal band for a low‑volume sports hybrid. This suggests the car has not been subjected to excessive high‑speed or heavy‑load duty, but the relatively modest annual mileage also raises the possibility of extended periods of inactivity, which can introduce age‑related wear on seals, batteries and corrosion‑prone parts even when mileage is low. The tyre advisory warrants immediate visual inspection of the near‑side rear tyre for any cracking, bulging or tread separation, and a check of the opposite tyres for matching wear patterns that could indicate alignment or suspension issues. On a test drive listen for any low‑frequency thumps or vibrations that might signal a deteriorating sidewall, and verify that the tyre age (DOT code) is not beyond ten years, as perishing rubber can fail abruptly regardless of tread depth. Given the i8’s hybrid architecture, request a diagnostic read‑out of the high‑voltage battery’s state of health and the 12 V auxiliary battery, looking for any loss of capacity, error codes or abnormal charge‑discharge behaviour, which can manifest as reduced electric‑assist range or intermittent electronic glitches. Beyond the tyres, inspect the suspension bushings, coil springs and damper units for any signs of corrosion, leakage or play, particularly around the rear sub‑frame where the advisory tyre is located. Examine the brake discs for surface rust, scoring or uneven wear that could cause shudder under hard application, and ensure the calipers move freely without binding. Check all fluid reservoirs – coolant, brake fluid and windshield washer – for proper levels, colour and any signs of contamination, remembering that fluids in a vehicle of this age may have exceeded their calendar service intervals even if mileage is modest. Finally, confirm that the service book contains full manufacturer‑specified servicing stamps, especially for the hybrid system coolant and oil changes, as adherence to these intervals is critical to preserving the i8’s performance and long‑term reliability.
