We continue our reviews on electric or hybrids cars, today we talk about BMW i8. The BMW i8 is ready to revolutionise its vehicle class. As the first sports car with the consumption and emission values of a compact car.
The strength of the plug-in hybrid lies, among other factors, in the perfect synchronisation of electric motor and combustion engine, which makes itself apparent in maximum efficiency and dynamics on the road. The first sports car that even accelerates the zeitgeist.
The production BMW i8 was designed by Benoit Jacob. The production version was unveiled at the 2013 International Motor Show Germany, followed by 2013 Les Voiles de Saint-Tropez. It features butterfly doors, head-up display, rear-view cameras and partially false engine noise. Series production of customer vehicles began in April 2014. It is the first production car with laser headlights, reaching further than LED lights.
The i8 has a low vehicle weight of 1,485 kg (3,274 lb) (DIN kerb weight) and a low drag coefficient (Cd) of 0.26. In all-electric mode the BMW i8 has a top speed of 120 km/h (75 mph). In Sport mode the i8 delivers a mid-range acceleration from 80 to 120 km/h (50 to 75 mph) in 2.6 seconds. The electronically controlled top speed is 250 km/h (160 mph).
Range and fuel economy
The production i8 has a 7.1 kWh lithium-ion battery pack with a usable capacity of 5.2 kWh and intelligent energy management that delivers an all-electric range of 37 km (23 mi) under the NEDC cycle. Under the EPA cycle, the range in EV mode is 15 mi (24 km), with a gasoline consumption of 0.1 gallons per 100 mi, and as a result, EPA's all-electric range is zero. The total range is 330 mi (530 km).
The U.S. Environmental Protection Agency's ‘14 edition of the: "Light-Duty Automotive Tech, Carbon Dioxide Emissions, and Fuel Economy Trends" introduced utility factors for plug-in hybrids to represent the percentage of miles that will be driven using electricity by an average driver, in electric only or blended modes. The BMW i8 has a utility factor in EV mode of 37%, compared with 83% for the BMW i3 REx, 66% for the Chevrolet Volt, 65% for the Cadillac ELR, 45% for the Ford Energi models, 43% for the McLaren P1, 39% for the Porsche Panamera S E-Hybrid, and 29% for the Toyota Prius PHV.
