Powered by a high-performance plug-in hybrid system combining a 1.5-liter, three-cylinder turbodiesel engine with two electric motors.

Total system output of 356 horsepower and 800 Nm (590 lb-ft) of torque, enabling 0–100 km/h (62 mph) acceleration in 4.8 seconds.

Electronically limited to 250 km/h (155 mph).

It consumed just 3.76 liters per 100 km (approx. 75 mpg imp) with CO2 emissions of 99 g/km.

Capable of driving up to 50 km (31 miles) on pure electric power alone.

Achieved an exceptionally low drag coefficient of 0.22, utilizing "air curtain" technology and specialized 21-inch wheels with blade profiles to reduce turbulence.

Built using a mix of aluminum and carbon fiber to keep the weight at approximately 1,395 kg.

A design philosophy where surfaces overlapped to create a visual sense of lightness and transparency, notably in the glass doors and roof.

Large doors that opened upwards, providing access to both front and rear seats.

The system derived from aerospace technology to convert heat from the exhaust into electricity to power the onboard network.

The concept's striking futuristic look and high-tech features were so well-received that BMW moved it into series production as the BMW i8, which debuted in 2013 and remained largely faithful to the original "Vision" design.
