The BMW i8 is a plug-in hybrid sports car developed by BMW. The i8 is part of BMW’s electric fleet “Project i” being marketed as a new sub-brand, BMW i. The 2015 model year BMW i8 has a 7.1 kWh lithium-ion batterypack that delivers an all-electric range of 37 km (23 mi) under the New European Driving Cycle. Under the United States Environmental Protection Agency cycle, the range in EV mode is 24 km (15 mi) with a small amount of gasoline consumption. Its design is heavily influenced by the BMW M1 Homage concept car, which in turn pays homage to BMW’s last production mid-engined sports car prior to the i8: the BMW M1.
The BMW i8 can accelerate from a dead-stop to 100 km/h (62 mph) in 4.4 seconds and has an electronic limited top speed of 250 km/h (155 mph). The BMW i8 has a fuel efficiency of 2.1 L/100 km (134.5 mpg‑imp; 112.0 mpg‑US) under the NEDC test with carbon emissions of 49 g/km. The EPA rated the i8 combined fuel economy at 76 MPGe (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent) and 29 miles per gallon (6.7L) when running in pure gasoline mode (after the battery is drained empty).
The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany. The production version of the BMW i8 was unveiled at the 2013 Frankfurt Motor Show. The i8 was released in Germany in June 2014. Deliveries to retail customers in the U.S. began in August 2014. By early November 2016 global sales since mid-2014 totaled more than 10,000 BMW i8s, making the i8 the world’s top selling plug-in electrified sports car. The top selling markets are the United States, the United Kingdom and Germany.
