The concept study was designed as a technology platform for further development of BMW (development code I12). Energy saving techniques have been previously installed in existing models is the BMW Vision EfficientDynamics from the outset an overall concept worden.Karosserie designed to save energy and drive were designed specifically saving aspects as energy.
BMW announced the Vision EfficientDynamics from the end of 2013 to build as a production vehicle. At the IAA 2011, the follow-up study called BMW i8 was shown. In March 2014, BMW released a first Price list with technical details. The first 8 Series vehicles were delivered to customers on June 5, 2014 at an event at BMW Welt in Munich
The model-specific, developed by the BMW Group and made the BMW i8 plug-in hybrid system consists of a compact 1.5-liter three-cylinder petrol engine with TwinPower Turbo technology, an electric motor and a rechargeable also on conventional household electrical outlets Lithium ion battery. The internal combustion engine with a maximum torque of 320 Nm develops 170 kW (231 hp) and drives the rear wheels. The electric motor with 96 kW (131 hp) rated power and 250 Nm of torque derives its power to the front axle. The total capacity is 266 kW so (362 hp), the 4.4 s in the vehicle accelerates from 0 to 100 km / h and allows a top speed of electronically limited 250 km / h. Energy is stored in 98 lithium polymer cells. The battery has a usable capacity of 5.2 kWh, which corresponds to a range of 20 up to 30 km in pure electric mode. The contents of the fuel tank is 30 liters. The BMW i8 has a drag coefficient (Cd value) of 0.26. The use of light and crash-proof material CFRP leads at least the same strength to weight savings of 50 percent compared to steel or approximately 30 percent compared with aluminum. - Electeric Sports Car : BMW i8 is Vision EfficientDynamics
