“According to BMW, the beautiful glass seen on the doors of the i8 Concept will be replaced by conventional materials, a request that was mainly driven by customers who requested more interior cabin privacy.
The i8 Concept combines the advantages of two different drive systems – an electric motor and an internal combustion engine. The electric motor is not a secondary power source, but rather an equal partner of the internal combustion engine. The major change is a new 1.5 liter petrol engine replacing the initial diesel unit of same capacity. The engine is mounted at the rear and drives via a dual-clutch gearbox.
The weight of 1480kg is the equivalent to a power-to-weight ratio of 236 horsepower per 1000 kilograms.”
