About the BMW i8
Launched in 2014, the BMW i8 represented a bold statement in sustainable performance motoring. Its futuristic design, featuring scissor doors and aerodynamic bodywork, remains eye-catching today. The powertrain combines a 1.5-litre three-cylinder petrol engine with an electric motor, delivering 369bhp while achieving up to 134mpg on the NEDC cycle and emitting just 49g/km CO2. The i8 Roadster joined the range in 2018, offering open-top thrills. Production ended in 2020, making all UK examples used cars with varying ownership histories.
Standard equipment was generous, including LED headlights, leather upholstery, digital instruments and a comprehensive infotainment system. Despite its supercar appearance, the i8 offers reasonable practicality with a 154-litre boot and surprisingly comfortable ride quality. The electric-only range of around 23 miles suits urban commuting, while the petrol engine ensures longer journeys pose no range anxiety.
What Affects the Price of a Used BMW i8
Model year significantly impacts value, with earlier 2014-2015 cars starting from £8,000 to £45,000, while later models command £40,000 to £55,000. The 2018 facelift brought increased power (374bhp) and minor styling updates, adding a premium. Roadster variants typically command £5,000-£10,000 more than equivalent Coupés due to rarity and desirability.
Mileage is crucial—low-mileage examples under 20,000 miles attract premium prices, while higher-mileage cars beyond 60,000 miles see significant depreciation. Specification matters too, with desirable options including the Laser Light package, Harman Kardon sound system and ceramic brakes. Full BMW service history is essential for maintaining value, as hybrid system repairs can be costly outside warranty. Battery condition affects price substantially, with degraded battery packs reducing electric range and overall appeal.
Colour combinations influence desirability, with Crystal White and Sophisto Grey being popular choices. The distinctive blue exterior accents can divide opinion. Regional pricing varies, with London and Southeast examples often commanding higher prices than similar cars elsewhere in the UK.
Tips for Buying a Used BMW i8
Always verify battery health—request a diagnostic check to confirm the high-voltage battery retains adequate capacity. Reduced electric range indicates expensive future repairs. Check the service history meticulously, ensuring all hybrid system updates and recalls have been completed. BMW's extended warranty or approved used programmes provide valuable protection given potential repair costs.
Inspect the carbon fibre passenger cell for any damage, as repairs are extremely expensive. Examine the scissor doors carefully—mechanism faults can cost thousands to rectify. Test all electrical systems thoroughly, including the digital displays, cameras and parking sensors, as faults are common and costly to fix.
Consider running costs beyond purchase price: insurance sits in high groups, tyres are expensive and bespoke, and battery replacement can exceed £20,000. Ensure charging infrastructure suits your needs—the i8 uses a Type 2 connector and takes around 3 hours to charge from empty. Budget for annual servicing at BMW specialists, typically £400-£800 depending on requirements. Check MOT history for suspension wear and brake issues, both common on the i8.
