The BMW i3 has been in the limelight lately, but BMW has just confirmed plans to introduce the i8 at the Frankfurt Motor Show.

BMW has announced plans to introduce the i8 at the Frankfurt Motor Show.

Set to be shown alongside the i3, the i8 is described as a contemporary plug-in hybrid sports car that combines impressive performance with the fuel consumption of a small car.

The company declined to release specifications but the model is expected to feature a tubocharged three-cylinder petrol engine and an electric motor that develops 170 HP (125 kW) and 250 Nm (184 lb-ft) of torque. This setup could enable the i8 to accelerate from 0-100 km/h in less than five seconds, consume less than 3 L/100km (78.4 mpg US / 94.1 mpg UK) and travel up to 35 km (20 miles) on electricity alone.

BMW will also use the Frankfurt Motor Show to introduce the 4-Series Coupe, the X5 and the Active Tourer Outdoor concept. Visitors will also be able to test drive a handful of models on an infinity-shaped track that is nearly 300 meters (984 feet) long and spans three levels.
