Insight summary

BMW I8 is a very rare model in this snapshot, with 2,060 represented vehicles and 0.00% of the active UK pool tracked by AutoRank. For the last 5 years, it has a pass rate of 90.5% from 12,498 MOT tests, with a reliability score of 62. The current pool shows an average of 43,674 miles and an average age of 8.7 years, while mature-fleet mileage is estimated at 51,286 miles. Hybrid electric leads the fuel split, followed by electric, and the most frequent defect themes are tyre condition, driveshaft boots and registration plate does not conform to the specified requirements. The practical read is that the BMW I8 looks a little better than average, but still rewards careful checks on mileage and maintenance.
