Overview[]

The BMW i8 is a plug-in hybrid sports car developed by BMW. The i8 is part of BMW's electrified fleet and is marketed under the BMW i sub-brand. The production version of the BMW i8 was unveiled at the 2013 Frankfurt Motor Show, and was released in Germany in June 2014. Deliveries to retail customers in the U.S. began in August 2014. A roadster variant was launched in May 2018. Production ended in June 2020.

The 2015 BMW i8 accelerates from 0 to 100 km/h (62 mph) in 4.4 seconds and has an electronic limited top speed of 250 km/h (155 mph). The 2015 model year i8 has a 7.1 kWh lithium-ion battery pack that delivers an all-electric range of 37 km (23 mi) under the New European Driving Cycle. Under the U.S. EPA cycle, the range in EV mode is 24 km (15 mi). The battery capacity of both, BMW i8 Roadster and the i8 Coupé, was increased to 11.6 kWh in 2018, allowing the NEDC electric range to rise to 55 km (34 mi) for the coupé and to 53 km (33 mi) for the roadster.

The BMW i8 coupé 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/100 km) when running in pure gasoline mode.

Roadster Variant[]

BMW I8 Roadster

The BMW i8 Spyder concept was unveiled at the 2012 Beijing Auto Show. In October 2016, BMW announced that the roadster variant would be added to the BMW i line-up in 2018. The production version of the BMW i8 Roadster was premiered in late 2017, and delivery of the first 18 exclusive first edition units took place in May 2018.

The battery cell capacity of both models, coupé and roadster, was increased from 20 to 34 Ah and a gross energy content of 11.6 kWh. At the same time, optimized battery cell technology made it possible to increase the peak output of the electric motor by 9 kW/12 hp to 105 kW/143 hp. These improvements made possible for the BMW i8 Coupé to accelerate from zero to 100 km/h in 4.4 seconds, while the BMW i8 Roadster takes 4.6 seconds. Both models reach a top speed of 250 km/h. The all-electric range rose to 55 km (34 mi) for the BMW i8 Coupé and to 53 km (33 mi) for the BMW i8 Roadster. The BMW i8 Roadster has only 2 seats, and the roof is an electric 2-piece unit, which neatly folds into the space where the rear seats would normally be.
