BMW Asia and Prestige Automobile Ltd. introduced the first-ever BMW i8 Roadster, a car that takes the BMW i8’s combination of locally emission-free mobility and high-calibre performance and sprinkles the drop-top driving experience into the mix. 
The first-ever BMW i8 Roadster exudes a whole new sensation of freedom, opening the door to virtually silent motoring and bringing an extra edge of purity to open-air motoring.
The first-ever BMW i8 Roadster is based on the LifeDrive vehicle architecture designed for BMW i cars. The aluminium Drive module brings together the powertrain, high-voltage battery, suspension, crash system and structural functions, while the Life module takes the form of a passenger cell hewn from carbon-fibre-reinforced plastic (CFRP).
The BMW i8 has performed the role of sports car of the future with extraordinary success since the day it was launched. The progressively designed 2+2-seater doubles up as an eye-catching object of desire and a technological pioneer. Indeed, the i8 has been the world’s highest-selling hybrid sports car since it first hit the roads in 2014 and has collected an array of awards in recognition of its visionary design and trailblazing vehicle concept.
The first-ever BMW i8 Roadster also benefits from a low-weight construction, complete with low centre of gravity and even weight distribution. The aerodynamically optimised exterior – with model-specific gullwing doors and a soft-top roof that also displays great visual lightness – is a fine exponent of the signature BMW i design language. The result is a two-seater boasting a distinctive and elegantly stretched silhouette, and delivering an immediate promise of instantaneous power ready to be unleashed.
Opening the roof raises the rear window automatically by around 30 millimetres into a comfort position. This allows it to mimic the effect of a conventional draught stop in reducing air turbulence inside the cabin and ensuring those on board can enjoy the pleasure of open-top driving pleasure in comfort. The driver can adjust the height of the rear window at the touch of a button and thus control the impact of the inflowing air as desired.
Intelligent lightweight design and innovative production technology also play a key role in the construction of the soft-top. For example, aluminium elements connecting the roof mechanism with the body of the first-ever BMW i8 Roadster are produced in a new 3D printing process. This manufacturing method for aluminium components breaks new ground in the automotive industry and allows the topologically optimised bracings to be produced in a geometric form, which would not be possible using conventional casting techniques and ensures an optimum balance between component rigidity and weight.
Rigorously further developed BMW eDrive technology powers the first-ever BMW i8 Roadster. The number of driving situations where the electric motor is solely responsible for powering the car has been significantly increased. Underpinning this new level of locally emission-free electric mobility is the updated version of the lithium-ion battery developed for the BMW i8.
The high-voltage unit is located centrally in the car’s underbody and its cell capacity is up from 20 to 34 Ah. All of which means the electric motor has more energy at its disposal. Plus, the cell configuration allows a 9 kW/12 hp increase in peak output to 105 kW/143 hp, lacing quick sprints on pure-electric power with an even sharper streak of dynamism.
The electric range of the i8 has also been increased. The first-ever BMW i8 Roadster can now cover up to 53 kilometres with zero local emissions in the NEDC test cycle. And that broadens the reach of all-electric mobility well beyond the city limits.
The BMW i8 is the world’s first sports car to be developed from the outset primarily under the banner of sustainability. Groundbreaking lightweight design, systematic improvement of aerodynamics and advanced plug-in hybrid technology form the mainstays of a trailblazing concept that completed its journey to reality with the car’s launch in 2014.
The framework for the concept’s implementation was provided by the brand new LifeDrive vehicle architecture for BMW i models, whose horizontally split structure comprising an aluminium chassis and a CFRP passenger cell offers an exceptional degree of design freedom.
The first-ever BMW i8 Roadster translates the unmistakable BMW i design language to another vehicle concept, fusing the dynamic proportions of the i8 with signature roadster features to give it a character all of its own.
The BMW i Wallbox Plus makes home charging particularly easy and convenient. The latest version of the Wallbox allows the high-voltage battery to be recharged at a rate of up to 3.7 kW, meaning that charging can be completed in under three hours.
