The i8 achieves exceptional visual drama and notable engineering novelty, but it does not reach the performance, drivetrain theatre or dynamic threshold of a true supercar.
The score should be interpreted as a threshold model, not a consumer buying guide. The framework asks whether the vehicle satisfies a supercar definition, not whether it is generally desirable.
