History
Previewed by the Vision EfficientDynamics concept car, the i8 was part of BMW's "Project i" and was marketed as a new brand, BMW i, sold separately from BMW or Mini. The BMW i3, launched for customers in Europe in the fourth quarter of 2013, was the first model of the i brand available in the market, and it was followed by the i8, released in Germany in June 2014 as a 2015 model year. Other i models were expected to follow.The turbodiesel Vision EfficientDynamics concept car was unveiled at the 2009 International Motor Show Germany, In 2010, BMW announced the mass production of the Vision EfficientDynamics concept in Leipzig beginning in 2013 as the BMW i8. The BMW i8 gasoline-powered concept car destined for production was unveiled at the 2011 Frankfurt Motor Show. The production version of the BMW i8 was unveiled at the 2013 International Motor Show Germany. The following are the concept and pre-production models developed by BMW that preceded the production version. When BMW i sponsored the ABB FIA Formula E World Championship, they announced that they would provide support vehicles; the i8 operated as the official safety car.

While Jochen Paesen took care of the main interior theme, Markus Speck was in charge of the seats, all the visible structure, and some details. Felix Baerlin supported Jochen Paesen on details including the steering wheel and center console.
The vehicle was unveiled at the 2009 International Motor Show Germany, followed by Auto China 2010.
BMW i8 Concept (2011)
The BMW i8 Concept plug-in hybrid electric vehicle included an electric motor located in the front axle powering the front wheels rated and, a turbocharged 1.5-liter 3-cylinder gasoline engine driving rear wheels rated and of torque, with combined output of and, a lithium-ion battery pack that allowed an all-electric range of. All four wheels provided regenerative braking. The location of the battery pack in the energy tunnel gave the vehicle a low centre of gravity, enhancing its dynamics. Its top speed was electronically limited to and was expected to go from 0 to 100 km/h in 4.6 seconds. Under normal driving conditions the i8 was expected to deliver under the European cycle. A full charge of the battery would take less than two hours at 220 V. The positioning of the motor and engine over the axles resulted in 50/50 weight distribution.The vehicle was unveiled at the 2011 International Motor Show Germany, followed by CENTER 548 in New York City, 42nd Tokyo Motor Show 2011, 82nd Geneva Motor Show 2012, BMW i Born Electric Tour at the Palazzo Delle Esposizioni at Via Nazionale 194 in Rome, and Auto Shanghai 2013.
This concept car was featured in the film Mission: Impossible – Ghost Protocol.
BMW i8 Concept Spyder (2012)
The BMW i8 Concept Spyder included a slightly shorter wheelbase and overall length compared to the BMW i8 Concept, carbon-fiber-reinforced plastic Life module, drive modules made primarily from aluminum components, interlocking of surfaces and lines, screen display, off-white outer layer, and orange-toned naturally tanned leather upholstery.The vehicle was unveiled at Auto China 2012 in Beijing where it won Concept Car of the Year, followed by the 83rd Geneva International Motor Show 2013. The designer of the BMW i8 Concept Spyder was Richard Kim.
BMW i8 coupe prototype (2013)
The design of the BMW i8 coupe prototype was based on the BMW i8 Concept. The BMW i8 prototype had an average fuel efficiency of less than under the New European Driving Cycle with carbon emissions of less than 59 g/km. The i8 with its carbon-fiber-reinforced plastic passenger cell lightweight, aerodynamically optimized body, and BMW eDrive technology offered the dynamic performance of a sports car, with an expected sprint time of less than 4.5 seconds using both power sources. The plug-in hybrid system of the BMW i8 comprised a three-cylinder, 1.5-liter BMW TwinPower Turbo gasoline engine combined with BMW eDrive technology used in the BMW i3 and developed maximum power of. The BMW i8 was the first BMW production model to be powered by a three-cylinder gasoline engine and the resulting specific output of per liter of displacement was on par with high-performance sports car engines and was the highest of any engine produced by the BMW Group.File:London 01 2013 BMW Vision Efficient Dynamics 5684.jpg|thumb|left|BMW Vision Efficient Dynamics concept exhibited at the BMW i store in Park Lane, London.
The BMW i8's second power source was a hybrid synchronous electric motor specially developed and produced by the BMW Group for BMW i. The electric motor developed maximum power of and produced its maximum torque of around from a standstill. Typical of an electric motor, responsive power was instantly available when starting and this continued into the higher load ranges. As well as providing a power boost to assist the gasoline engine during acceleration, the electric motor could also power the vehicle by itself. Top speed in electric mode was approximately, with a maximum driving range of up to. Linear acceleration was maintained even at higher speeds since the interplay between the two power sources efficiently absorbed any power flow interruptions when shifting gears. The model-specific version of the high-voltage 7.2 lithium-ion battery had a liquid cooling system and could be recharged at a conventional household power socket, at a BMW I Wallbox, or at a public charging station. In the US, a full recharge took approximately 3.5 hours from a conventional 120 V, 12 amp household circuit or approximately 1.5 hours from a 240 V Level 2 charger.
The driver could select several driving modes: SPORT, COMFORT, and ECO PRO. Using the gear selector, the driver could either select position D for automated gear selection or could switch to SPORT mode. SPORT mode offered manual gear selection and at the same time switched to sporty drive and suspension settings. In SPORT mode, the engine and electric motor delivered extra performance, accelerator response was faster, and the power boost from the electric motor was maximized. And to keep the battery topped up, SPORT mode also activated maximum energy recuperation during overrun and braking as the electric motor's generator function, which recharged the battery using kinetic energy, switched to a more powerful setting. The Driving Experience Control switch on the center console offered a choice of two settings. On starting, COMFORT mode was activated, which offered a balance between performance and fuel efficiency, with unrestricted access to all convenience functions. Alternatively, the ECO PRO mode could be engaged, which, on the BMW i8 as on other models, supported an efficiency-optimized driving style. In this mode, the powertrain controller coordinated the cooperation between the gasoline engine and the electric motor for maximum fuel economy. On deceleration, the intelligent energy management system automatically decided, in line with the driving situation and vehicle status, whether to recuperate braking energy or to coast with the powertrain disengaged. At the same time, ECO PRO mode also programmed electrical convenience functions such as the air conditioning, seat heating, and heated mirrors to operate at minimum power consumption, but without compromising safety. The maximum driving range of the BMW i8 on a full fuel tank and with a fully charged battery was more than in COMFORT mode, which could be increased by up to 20% in ECO PRO mode. The BMW i8's ECO PRO mode could also be used during all-electric operation. The vehicle was then powered solely by the electric motor. Only if the battery charge dropped below a given level, or under sudden intense throttle application such as kick down, was the internal combustion engine automatically activated.
The vehicle was unveiled in BMW Group's Miramas test track in France.
Production version
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. Its design was 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 featured butterfly doors, head-up display, rear-view cameras and partially false engine noise.

The combined fuel economy when running only with gasoline was for city driving, and on the highway.
The U.S. Environmental Protection Agency's 2014 edition of the Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends introduced utility factors for plug-in hybrids to represent the percentage of miles that would be driven using electricity by an average driver, in electric only or blended modes. The BMW i8 Coupé had an EV mode utility factor 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.
The battery capacity of both models launched in 2018, BMW i8 Roadster and the i8 Coupé, was increased to a gross energy content of 11.6 kWh. This, and other improvements, increased the all-electric range to for the BMW i8 Coupé and for the BMW i8 Roadster, both under the NEDC test. Under the U.S. EPA driving cycle, the range only increased from to.
