BMW i is synonymous with visionary mobility concepts and a new definition of premium quality that is strongly focused on sustainability. Following the world debut of the first production model, the BMW i3, the BMW Group's next step will be to extend this revolutionary answer to the future challenges facing personal mobility to the sports car segment in the BMW i8. This plug-in hybrid model is the most progressive sports car of our time, extending the basic BMW i philosophy of sustainability to a new vehicle segment.

The BMW i8 fulfills the promise of The Ultimate Driving Machine in a revolutionary and mold-breaking form. This is reflected in a highly emotive design, dynamic sports car performance, and fuel efficiency and emissions figures worthy of a small car. Pairing an exceptionally lightweight, aerodynamically optimized body with cutting-edge BMW eDrive technology, a compact, turbocharged 1.5-liter BMW TwinPower Turbo gasoline engine and intelligent energy management, the BMW i8 marks the next stage in the evolution of the Efficient Dynamics strategy. Its revolutionary approach achieves an unprecedented balance between performance and fuel efficiency. Thanks to its carbon-fiber-reinforced plastic (CFRP) passenger cell, the BMW i8 sets new standards for a plug-in hybrid vehicle in terms of low weight. It can operate solely on electric power, which means no tailpipe emissions, and offers the dynamic performance of a sports car, with an expected 0 - 60 mph sprint time under 4.5 seconds.

The BMW i8 was designed from the outset as a plug-in hybrid sports car, with the emphasis on agile performance and outstanding efficiency. Its characteristic BMW i LifeDrive architecture provides the best possible basis for lightweight design. Its main components are the aluminum Drive module, which incorporates the internal combustion engine and electric motor, the battery, the power electronics and the chassis components, along with structural and crash functions, and the Life module, which essentially comprises the 2+2-seater CFRP passenger cell. This architecture also gives the BMW i8 a very low center of gravity and a near-perfect 50:50 axle load ratio, both of which increase its agility.

The BMW i8's plug-in hybrid system is specific to this model. Developed and produced by the BMW Group, it marks the next step in the evolution of the Efficient Dynamics programme. A compact three-cylinder petrol engine with BMW TwinPower Turbo technology is combined with an electric drive system and a lithium-ion battery which can be recharged at a standard household power socket. The 231 hp (170 kW) gasoline engine sends its power to the rear wheels, while the 131 hp (96 kW) electric motor powers the front wheels. This configuration offers all-electric driving capability with a range of up to approx. 22 miles (35 kilometers) and a top speed of approximately 75 mph (120 km/h). With both drive systems engaged, it also offers road-hugging all-wheel-drive performance with powerful acceleration and dynamic torque vectoring during sporty cornering. The more powerful of the two powerplants drives the rear wheels. The hybrid system supplements this with power from the electric motor to deliver typical BMW driving pleasure combined with groundbreaking efficiency. Calculated using the EU test cycle for plug-in hybrid vehicles, the average fuel efficiency of the BMW i8 at model launch will be less than 2.5 liters/100 km, which equates to approximately 95 miles per US gallon, with CO2 emissions of less than 59 grams per kilometer.
