This open-top BMW i8 Spyder concept will be turned into a production variant of the petrol-electric hybrid supercar in 2015, BMW sources have told Autocar.
The i8 Spyder is the third pre-production version of the revolutionary 90mpg-plus, 155mph supercar. It’s set for its first public airing at the Beijing motor show later this month.
This concept is said to give extra clues to the production coupé, which is due to go on sale in late 2014. Of note are the solid doors, which replace the transparent sides of the previous concepts.
There are other subtle differences from the two previous concepts. The kidney grille is blanked off to cut aerodynamic drag and the ‘layered surfacing’ styling treatment has evolved slightly.
With its open-roof design, the i8 Spyder has a new, free-standing windscreen and conventional door glazing that integrates with fixed rear three-quarter side panels.
To provide roll-over protection and boost chassis stiffness, there are prominent safety hoops, faired-in by body panels, at the rear of the cabin.
Although this concept leaves the design of the roof unclear, BMW insiders suggest that a removable panel, probably fashioned from carbonfibre, is the favoured solution.
The rear end has also been modified, with a flat, transparent engine cover in place of the sloping coupé roofline. It doubles as the luggage cover, over a wide but shallow stowage space.
As with all future BMW ‘i’ sub-brand models, the Spyder is based around a lightweight carbonfibre-reinforced plastic structure clothed in body panels of the same material. It is 4480mm long, 1922mm wide and 1208mm tall. That makes it 130mm shorter, 142mm wider and 187mm lower than a 335i cabriolet.
