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 process of building BMW i vehicles is just as important as the final result. That’s why the BMW i3 and BMW i8 are assembled in factories as smart as the vehicles themselves. In fact, the BMW i manufacturing facility in Leipzig, Germany is BMW’s most sustainable automotive plant, exclusively relying on renewable energy sources. And here in the USA, carbon fiber threads are manufactured at the Moses Lake, Washington, carbon fiber plant, which is completely powered by locally generated hydropower. Overall, the production of the BMW i3 uses 50% less energy and 70% less water.1

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.

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.

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.

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.
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.
It started with a vision. A vision to completely reimagine the future of mobility and rethink what it means to drive an electric vehicle. And here we are—this vision is now a reality. Meet the all-electric BMW i3 and the plug-in hybrid BMW i8. It’s time to forget everything you once thought about electric cars and imagine a world powered by performance, design, innovation, and efficiency. This is the world of BMW i.
For the 2011 car, which was much closer to the production version, the original concept’s diesel engine had been replaced by a gasoline engine. That is BMW’s new 1.5-liter 3-cylinder engine—which is used in the new generation of Mini Coopers and pegged for a new front-wheel-drive BMW model.
This is the first time we’ve driven and tested a U.S.-spec i8. (The car BMW loaned us was a 2016 model, but nothing significant changes for 2017 except the addition of a Protonic Red Edition; it swaps the cool blue/black color scheme on our test car to an even more visible, Columbus, Ohio–friendly red/gray combo.) Our previous stories, including an instrumented test and a feature, have been based on drives in European cars. This was our first opportunity to meter the electricity going into the car so that we can report an observed fuel-economy figure, which we’ve only been able to estimate in the past. Including all the charges, we averaged 33 MPGe. While this may seem low for a three-cylinder hybrid, know that the EPA attaches 28- and 29-mpg numbers to the i8’s conventional city and highway ratings, which are achieved when the car is operating as a regular hybrid. Only when using the relatively small 7.1-kWh lithium-ion battery pack alone, what the EPA calls “charge-depleting” mode, will the i8 approach its EPA electricity-plus-gasoline combined rating of 76 MPGe, and even then just for short stints. The i8 averaged 38 MPGe on our 200-mile, 75-mph highway economy test, the first 16 miles of which were completed using only electric drive.
Both cars are built in two parts: an aluminum platform holds the battery, electric motor, and other powertrain components, while a body shell made of carbon-fiber-reinforced plastic sits on top. The combination is light, durable, and cutting-edge, with BMW about to become the world’s leading automaker in the use of carbon fiber in mass production. The total weight of the BMW i8 is 3,455 pounds.
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.
