World’s first production car with laser light. Introduction of the optional BMW laser headlights is scheduled for autumn 2014, when the BMW i8 will become the world’s first production car to offer this innovative lighting technology. BMW laser headlights are around 30 per cent more energy-efficient than the BMW i8’s standard LED headlights and provide considerably more powerful road illumination, with a range of up to 600 metres. Highly concentrated beams of light from high-performance laser diodes act on a fluorescent phosphor material inside the headlight, which projects a sharply focused beam of light onto the road. The laser headlights produce a light similar to natural daylight and are therefore always easy on the eye.
BMW eDrive: Sports car powertrain of the future. The BMW i8’s plug-in hybrid system comprises a 170 kW/231 hp, 320 Nm (236 lb-ft) three-cylinder petrol engine with BMW TwinPower Turbo technology and a 96 kW/131 hp, 250 Nm (184 lb-ft) hybrid synchronous electric motor. The BMW eDrive system also includes a lithium-ion high-voltage battery (with a usable capacity of 5,2 kWh) and intelligent energy management that uses the combined output of 266 kW/362 hp to provide breathtaking performance and maximum efficiency, while always taking into account the driving situation and driver requirements. The excellent balance between driving pleasure and fuel economy is aided by a low vehicle weight of 1,485 kg (DIN kerb weight) and an unusually good drag coefficient (Cd) for a sports car of 0.26.
In zero-emission all-electric mode, the BMW i8 has a top speed of 120 km/h (75 mph) and a range of 37 kilometres (23 miles) within the EU test cycle. Depending on whether the plug-in hybrid sports car’s lithium-ion battery is recharged at a household power socket or BMW i Wallbox, or at a public charging station, charging times range from less than two up to three hours. In Sport mode the BMW i8 offers mid-range acceleration from 80 to 120 km/h (50 to 75 mph) in 2.6 seconds. The electronically governed top speed is 250 km/h (155 mph).
