The final stretch on the way to the “Hall of Fame” of BMW sports cars: Six years after its market launch, the BMW i8 ends its product life cycle. When production of the BMW i8 Coupé (fuel consumption combined: 1.8 l/100 km; combined power consumption: 14.0 kWh/100 km; combined CO2 emissions: 42 g/km*) and the BMW i8 Roadster (combined fuel consumption: 2.0 l/100 km; combined power consumption: 14.5 kWh/100 km; combined CO2 emissions: 46 g/km) ceases, the plug-in hybrid sports cars will have long secured their place among the company’s milestones.
The BMW i8 started its worldwide success story as a unique symbiosis of futuristic design and pioneering technology. The BMW Group’s first plug-in hybrid model paved the way for driving pleasure that was as dynamic as it was sustainable and became the epitome of the fascination of driving with electrified drive technology. It laid the foundation for the BMW Group’s now broad range of plug-in hybrid models.
At the same time, the BMW i8 developed into the world’s most successful sports car with an electrified drive system. With more than 20 000 units sold since 2014, it achieved higher sales than all competitors in its segment combined.
The BMW Vision EfficientDynamics was already an enticing prospect for the future of individual mobility. The concept study presented at the International Motor Show (IAA) in Frankfurt in 2009 represented the promise of combining hallmark BMW driving pleasure and inspiring design with pioneering sustainability.
The study of a 2+2-seater sports car with gull-wing doors, a reinterpretation of the typical BMW design language, plug-in hybrid system and four-wheel drive that is entirely geared towards aesthetics and efficiency, met with an overwhelming response. With the announcement that the central features of its design and technology would be transferred to a production vehicle of the new BMW i brand and thus start into a new era of driving pleasure the BMW Group soon triggered enthusiastic reactions.
The launchpad for a consistent electrification strategy.
The BMW i8 made its world premiere at the IAA motor show in 2013 together with the BMW i3. The double debut was the starting signal for implementing a comprehensive electrification strategy, with which the BMW Group set the early and consistent course for a model programme geared towards sustainable driving pleasure. Today the company is one of the world’s leading suppliers of vehicles with electrified drive systems.
Besides the purely electrically driven BMW i3 (fuel consumption combined: 0.0 l/100 km; combined power consumption: 13.1 kWh/100 km; combined CO2 emissions: 0 g/km), BMW i3s (combined fuel consumption: 0.0 l/100 km; combined power consumption: 14.6 – 14.0 kWh/100 km; combined CO2 emissions: 0 g/km) and MINI Cooper SE (fuel consumption combined:0.0 l/100 km; power consumption combined: 16.8 – 14.8 kWh/100 km; combined CO2 emissions: 0 g/km), plug-in hybrid models are available in all relevant segments, from the compact and mid-size class, through the BMW X models, to sports cars and luxury sedans. The BMW Group plans to expand its range to include 25 electrified models by 2023, more than half of which will run on electric power alone.
As a pioneer and flagship for driving pleasure with plug-in hybrid technology, the BMW i8 was the ideal vehicle for the job right from the start. And this not only applies to its role as Safety Car in the FIA Formula E Championship, which it already took on in 2014. The BMW i8 is the world’s first sports car that had been developed with sustainability in mind right from the outset. In particular, new paths were forged with the BMW i specific vehicle architecture and the plug-in hybrid system.
The combination of a passenger cell made of carbon fibre reinforced plastic (CFRP) with an aluminium chassis was just as revolutionary as the intelligently controlled interaction of the combustion engine and electric motor. The vehicle concept of a 2+2-seater, the aerodynamically optimized design, the intelligent lightweight construction and the innovative drive concept were aimed at resolving the contradiction between dynamics and efficiency that prevails in conventional automotive engineering.
As a result of this innovative approach, the BMW i8 offers the driving performance of a top-class sports car – combined with average fuel consumption at small car level.
The control of its plug-in hybrid system was designed both for dynamic power delivery and for the most efficient interaction of the two engines. The combustion engine with BMW TwinPower Turbo technology transfers its power to the rear wheels. The electric motor drives the front wheels.
The result is a hybrid-specific all-wheel drive with a noticeably positive influence on traction, agility and driving stability. This, and the spontaneous power delivery of the electric motor with a maximum torque of 250 Nm available immediately from standstill, means that the sporting character of the BMW i8 also comes into its own in purely electric and therefore locally emission-free driving. Up to 120 km/h can be reached in pure electric driving mode. The combined drive torque of both engines unleashes inspiring performance characteristics in the style of a high-performance sports car.
Driving dynamics and efficiency are also enhanced by the LifeDrive architecture typical for BMW i. The design principle of the BMW i8 was completely and exclusively geared to a plug-in hybrid drive from the ground up. The body structure and powertrain were developed as a conceptual unit, which helped the BMW i8 achieve the authentic character of a trailblazing sports car.
The passenger cell (life module) made of carbon fibre reinforced plastic (CFRP) and the drive module made of aluminium, which in addition to the engines, power electronics and chassis also includes the structural and crash functions, not only enabled a DIN empty weight of less than 1 500 kilograms, but also a balanced axle load distribution in the ratio 50 : 50. And since the high-voltage battery was placed centrally and low in the vehicle, the centre of gravity was shifted far down.
Innovation leader even beyond BMW eDrive drive technology.
Right from the start, the pioneering function of the BMW i8 extended far beyond establishing BMW eDrive technology in an iconic sports car. The extensive use of CFRP in the body structure and the clearly visible measures to reduce air resistance, set new standards in the areas of intelligent lightweight construction and aerodynamics. Together with the BMW i3, the plug-in hybrid sports car paved the way for innovative manufacturing technologies, with which the BMW Group became a pioneer in the use of CFRP in the industrial production of series-produced automobiles.
The experience gained at BMW i with this particularly light high-tech material secured the BMW Group lightweight construction expertise that is unique in the automotive industry and has since been used in the development of CFRP components for other BMW models.
The progressive character of the BMW i8 was also evident at first glance in the expressive yet aerodynamically optimised design of its exterior. Its dynamic sports car proportions and the gull-wing-like doors that swing open to the front still attract attention today. The flat front end, the almost completely closed BMW kidney grille, air curtains in the front apron, the covered underbody, contoured side skirts, the lines of the side section known as Stream Flow, and the air ducts between the rear lights and the roof frame also allow the wind to be directed in a targeted manner. It not only results in a low drag coefficient (Cd value) of 0.26, but also in an exceptionally favourable aerodynamic balance. The ideal ratio of air resistance and lift for driving dynamics and safety is characteristic of this and is achieved without additional spoiler attachments.
The selection of materials for the interior and in the production of the BMW i8 was focussed greatly on sustainability. The leather used for the surfaces of the seats and instrument panel is tanned with an extract of olive tree leaves. The starting material for the textile materials is a polyester granulate, which comes from recycled PET, among other things.
The holistic sustainability concept that is characteristic of BMW i vehicles extends from development and design to production, use and recycling and thus covers the entire value chain. Not only is the proportion of recycled plastics exceptionally high, most of the aluminium used in the BMW i8 is also either obtained by recycling or produced using regenerative energy. In addition, the electricity required for the production of the BMW i8 Coupé and the BMW i8 Roadster at the BMW plant in Leipzig comes from four wind turbines on the plant premises. The electrical energy required for carbon fibre production in Moses Lake in the US state of Washington is generated from 100% hydropower.
At its market launch, the BMW i8 was the world’s first series-produced car to be equipped with innovative laser headlights. Following its world premiere in the BMW i8, the BMW laser light was also introduced in other models – first in the luxury sedans of the BMW 7 Series and then in numerous other model series. The BMW laser light provides particularly intensive illumination of the road and a considerable increase in the range of the high beam. At the same time, the energy consumption is again significantly reduced, even compared to the already particularly efficient LED headlights.
In the field of drive technology, the forefather of all plug-in hybrid models in the BMW Group was also the pioneer of a new generation of combustion engines. A new 3-cylinder petrol engine with BMW TwinPower Turbo technology was used for the first time in the BMW i8. The 1.5 litre engine was characterised both by a particularly compact design and an exceptionally high specific power output. With 113 kW/154 hp per litre displacement, a new record for BMW series models was achieved.
BMW i8 Roadster: Fresh impulses for achieving sustainable driving pleasure.
With the world premiere of the BMW i8 Roadster, fresh impetus for sustainable driving pleasure was provided in autumn 2017. The open two-seater now offered the opportunity to experience the fascination of this visionary sports car in the open air – a truly pure experience in purely electric drive mode.
The output of the plug-in hybrid drive was also increased for the BMW i8 Coupé with the world premiere of the BMW i8 Roadster. Since then, the high-voltage storage battery of both models has had a cell capacity 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. In combination with the combustion engine, this resulted in a system output of 275 kW/374 hp. The BMW i8 Coupé now accelerates 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 electric range is now 55 kilometres for the BMW i8 Coupé and 53 kilometres for the BMW i8 Roadster.
Innovative production processes were used in the construction of the soft top for the roadster. For the first time, the aluminium connecting parts of the soft top mechanism to the bodywork were manufactured using a new type of 3D printing process. This manufacturing process for aluminium components, which is new to the automotive sector, makes it possible to produce the topology-optimised struts in a geometric shape that would not be possible using conventional casting methods and ensures an optimum balance between component rigidity and weight. Thanks to the expertise acquired by BMW i, additive manufacturing processes can now be used for a steadily increasing number of components and in models of various series.
A real winner right from the outset: Numerous awards for concept, design, technology, sustainability and driving pleasure.
No matter whether as an eye-catcher on the street or as a serial winner in jury evaluations and reader surveys: The BMW i8 impresses sports car fans and experts time and again. Five times in a row between 2015 and 2019 its plug-in hybrid drive won at least one title at the world-renowned “Engine of the Year Award”. In addition, the vehicle concept and technology of the BMW i8 have been awarded the “Auto Trophy” and the “Green Mobility Trophy” of the “Auto Zeitung” car magazine, the “International Paul Pietsch Award” of the “auto, motor und sport” car magazine and the “Car Connectivity Award” of “auto, motor und sport” and “Chip”, among others. The title “World Green Car” went to the plug-in hybrid sports car as well as the class victory in the “All-Wheel Drive Car of the Year” survey.
The British “Top Gear” magazine named the BMW i8 “Car of the Year”, as did the jury of “UK Car of the Year”. It was voted “Auto Test winner in green” by “Auto Test” and “Ökotrend”. Renowned awards such as the iF Design Award and the red dot Award confirmed the quality and charisma of its design.
Trendsetting definition of luxury and exclusivity.
With their progressive and exclusive character, the BMW i8 Coupé and the BMW i8 Roadster are integral parts of the latest BMW product initiative in the luxury segment. Just like the luxury sedans of the BMW 7 Series, the Sports Activity Vehicle BMW X7 and the sports cars of the BMW 8 Series, they also provide a unique mobility experience. In addition, the “Next Premium” character of the two plug-in hybrid sports cars is reflected in the BMW i Pure Impulse Experience programme created for the BMW i8. The programme for extended dialogue with customers, which is unique in the world, provides owners of a BMW i8 with exclusive access to visionary personalities as well as extraordinary cultural and travel experiences.
The exclusive edition models of the BMW i8 also added a further flair of individuality. The limited edition models are characterized by unique design features that make them a sought-after rarity. The BMW i8 Protonic Red Edition was presented at the beginning of 2016. Just one year later, the BMW i8 Protonic Frozen Black Edition and the BMW i8 Protonic Frozen Yellow Edition followed, which will remain the most exclusive edition worldwide with around 100 units.
Top-selling plug-in hybrid sports car and already a milestone in the history of the BMW Group.
The Leipzig plant is currently producing the 200 vehicles of the limited Ultimate Sophisto Edition of the BMW i8. One of the edition models was already manufactured in December 2019 as the 20 000th unit of the plug-in hybrid model. With this production volume, the BMW i8 has already outstripped many a legendary BMW sports by far. Among the milestones in the history of sports cars, its sales figures are well ahead of classics such as the BMW M1, of which only 399 units were produced for road use, and also ahead of the BMW Z8 roadster, which was built around 5 000 times.
In addition, the BMW i8 has held a global market share of more than 50 per cent in the segment of sports cars with electrified drive for years. The BMW i8 will be able to maintain this leading position until the middle of April 2020. Then the bestseller with plug-in hybrid drive will have finally achieved the status that the readers of “Auto Bild Klassik” attested it only a few months after its market launch. Already in 2014, they declared the BMW i8 the “classic of the future”.
