BMW i8: hybrid sports car, coupé and roadster
The BMW i8 is a plug-in hybrid sports car with a futuristic design, produced as a coupé from 2014 to 2020, and as a roadster from 2018 onwards. We look at the gearbox, versions, and what to check before buying a used i8.
i8 in brief
The i8 stands out with its upward-opening doors, low, wide body lines, and carbon fibre body. It's a sports car, but also a hybrid that can travel short distances on electric power alone.
The interior features two main seats and two small rear seats, suitable only for short trips. The boot is small, so the i8 is primarily for pleasure, not everyday use.
Which version to choose
Produced initially as a coupé, and later (from 2018) as a roadster with a retractable roof. Around 2018, the gearbox was updated with a larger battery and slightly more power.
Special editions, like the Protonic Red Edition or Ultimate Sophisto Edition, stand out with their colours and trim and are quite rare.
Gearbox and running costs
The i8 has a 1.5-litre three-cylinder turbo petrol engine at the rear and an electric motor at the front. Combined power initially was around 362 hp, later about 374 hp, with all-wheel drive.
Electric power is available for short distances, and the battery can be charged from the mains. Real-world running costs depend on driving style, but in the city, with a charged battery, they are very low.
What to check when buying a used i8
Request a diagnostic of the hybrid battery and check the charging function. Hybrid system repairs can be expensive.
Inspect the door mechanisms, the convertible top's fabric parts, and the roof (in the roadster). Check for any error messages and review the electronics.
Request the full BMW service history and check if all recall and update work has been completed.

Frequently asked questions
Is the i8 a genuine sports car?
It boasts a sporty design and quick acceleration, but its engine is small, and the hybrid drivetrain is geared towards economy as well. It's more of a tech showcase than a pure sports car.
How far can the i8 travel on electric power?
Only a short distance, which depends on the version and driving conditions. The range is greater after the 2018 update.
Is the i8 practical?
No — the boot is small, and the rear seats are cramped. It's a car for comfort first and foremost.
