The design of the BMW i8 coupe prototype was based on the BMW i8 Concept. The BMW i8 prototype has an average fuel efficiency of less than 2.5 L/100 km (113.0 mpg‑imp; 94.1 mpg‑US) under the New European Driving Cycle with carbon emissions of less than 59 g/km. The i8 with its carbon-fiber-reinforced plastic (CFRP) passenger cell lightweight, aerodynamically optimized body, and BMW eDrive technology offers the dynamic performance of a sports car, with an expected 0–100 km (0–60 mi) sprint time of less than 4.5 seconds using both power sources. The plug-in hybrid system of the BMW i8 comprises a three-cylinder, 1.5-liter BMW TwinPower turbo gasoline engine combined with BMW eDrive technology used in the BMW i3 and develops maximum power of 170 kW (230 hp). The BMW i8 is the first BMW production model to be powered by a three-cylinder gasoline engine and the resulting specific output of 115 kW (154 hp) per liter of displacement is on a par with high-performance sports car engines and is the highest of any engine produced by the BMW Group.

The BMW i8’s second power source is a hybrid synchronous electric motor specially developed and produced by the BMW Group for BMW i. The electric motor develops maximum power of 131 hp (96 kW) and produces its maximum torque of around 320 N·m (240 lbf·ft) from standstill. Typical of an electric motor, responsive power is instantly available when starting and this continues into the higher load ranges. As well as providing a power boost to assist the gasoline engine during acceleration, the electric motor can also power the vehicle by itself. Top speed in electric mode is approximately 120 km/h (75 mph), with a maximum driving range of up to 35 km (22 mi). Linear acceleration is maintained even at higher speeds since the interplay between the two power sources efficiently absorbs any power flow interruptions when shifting gears. The model-specific version of the high-voltage 7.2 lithium-ion battery has a liquid cooling system and can 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 takes approximately 3.5 hours from a conventional 120V, 12 amp household circuit or approximately 1.5 hours from a 220V Level 2 charger.

The driver can also select several driving modes: SPORT, COMFORT and ECO PRO. Using the gear selector, the driver can either select position D for automated gear selection or can switch to SPORT mode. SPORT mode offers manual gear selection and at the same time switches to very sporty drive and suspension settings. In SPORT mode, the engine and electric motor deliver extra performance, accelerator response is faster and the power boost from the electric motor is maximized. And to keep the battery topped up, SPORT mode also activates maximum energy recuperation during overrun and braking as the electric motor’s generator function, which recharges the battery using kinetic energy, switches to a more powerful setting. The Driving Experience Control switch on the center console offers a choice of two settings. On starting, COMFORT mode is activated, which offers a balance between sporty performance and fuel efficiency, with unrestricted access to all convenience functions. Alternatively, the ECO PRO mode can be engaged, which, on the BMW i8 as on other models, supports an efficiency-optimized driving style. On this mode the powertrain controller coordinates the cooperation between the gasoline engine and the electric motor for maximum fuel economy. On deceleration, the intelligent energy management system automatically decides, 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 programs 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 is more than 500 km (310 mi) in COMFORT mode, which can be increased by up to 20% in ECO PRO mode. The BMW i8’s ECO PRO mode can also be used during all-electric operation. The vehicle is then powered solely by the electric motor. Only if the battery charge drops below a given level, or under sudden intense throttle application such as kickdown, is the internal combustion engine automatically activated.

The i8 is part of BMW’s “Project i” and it is being marketed as a new brand, BMW i, sold separately from BMW or Mini. The BMW i3, launched for retail 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 are expected to follow.

Global deliveries to retail customers totaled 1,741 units in 2014, and 5,456 in 2015, totaling cumulative sales of 7,197 units worldwide through December 2015. In 2015 global sales of the BMW i8 exceeded the combined figure of all other hybrid sports cars produced by other manufacturers. The United States is the leading market with 4,108 units delivered through October 2016, followed by the UK with about 1,700 units sold through October 2016, and Germany with 986 i8s registered through September 2016. Since mid-2014 more than 10,000 BMW i8s have been sold worldwide by early November 2016, representing 10% of BMW global electrified model sales, and making the i8 the world’s top selling plug-in electrified sports car.

Deliveries started in the UK in July 2014, with pricing starting at GB£99,845. The BMW i8 qualifies for exemption from the London congestion charge, which is one of the factors driving its demand. The BMW i8 was eligible for the government’s GB£5,000 Plug-in Car Grant until February 2016. Despite being classified as category 2 vehicle, due to its purchase price the BMW i8 is no longer eligible for a grant. As part of changes implemented by the government to the grant scheme, from March 2016 plug-in vehicles with a retail price over GB£60,000 are ineligible for a grant.
BMW i8 Concept plug-in hybrid electric vehicle includes an electric motor located in the front axle powering the front wheels rated 96 kW (131 PS; 129 hp) and 250 N·m (184 lb·ft), a turbocharged 1.5-liter 3-cylinder gasoline engine driving rear wheels rated 164 kW (223 PS; 220 hp) and 300 N·m (221 lb·ft) of torque, with combined output of 260 kW (354 PS; 349 hp) and 550 N·m (406 lb·ft), a 7.2 kWh (26 MJ) lithium-ion battery pack that allows an all-electric range of 35 km (22 mi). All four wheels provide regenerative braking. The location of the battery pack in the energy tunnel gives the vehicle a low centre of gravity, enhancing its dynamics. Its top speed is electronically limited to 250 km/h (155 mph) and is expected to go from 0 to 100 km/h (0 to 60 mph) in 4.6 seconds. Under normal driving conditions the i8 is expected to deliver 80 mpg‑US (2.9 L/100 km; 96 mpg‑imp) under the European cycle. A full charge of the battery will take less than 2 hours using 220V. The positioning of the motor and engine over the axles results in optimum 50/50 weight distribution.
The BMW i8 is an icon of progress, marking an extraordinary evolution of The Ultimate Driving Machine.® As an innovative plug-in hybrid, it uses eDrive technology to combine the efficiency of an all-electric motor and the power of a TwinPower Turbo engine for an exhilarating driving experience that’s every bit BMW.
The i8 was the first BMW to use the company’s latest 1.5-liter turbo 3-cylinder engine, rated at 228 horsepower and 236 pound-feet of torque, powering the rear wheels through a 6-speed automatic transmission. The same engine is now found in a lower state of tune in the latest Mini Cooper line. The electric motor up front is rated at 96 kilowatts (131 hp) and 184 lb-ft of torque; it’s used for electric-only driving at speeds up to 75 mph.
The long wheelbase, short overhangs, precise lines, and sweeping silhouette give the appearance that the BMW i8 is surging forward even when it is standing still. The scissor doors of the BMW i8 provide an undeniable emotional and sporty allure that make it truly one-of-a-kind.
It’s entirely unclear whether more than a handful of six-figures sport coupe buyers care about reducing fuel consumption and sustainability. The innovative materials, advanced tech, and light weight of the BMW i8 have already made it a high-tech icon. It’s more of a sports car that’s comfortable as a touring car than an all-out track racer. Which is not to say that BMW isn’t considering higher-performance models down the road. Meanwhile, we anticipate that the company will have no problem selling every one they build.
The BMW i8 Concept Spyder included a slightly shorter wheelbase and overall length over the BMW i8 Concept, carbon-fibre-reinforced plastic (CFRP) Life module, drive modules made primarily from aluminium components, interlocking of surfaces and lines, 8.8-inch (22.4 cm) screen display, off-white outer layer, orange tone naturally tanned leather upholstery.
When a car looks this fast, it better live up to its appearance. The BMW i8 does exactly this with its innovative electric motor that sits on the front axle and the TwinPower Turbo 3-cylinder engine that drives the rear axle. When combined, they deliver a total output of 357 horsepower, 420 lb-ft of torque, and can reach 0 to 60 mph in 4.2 seconds.
