Even though some forums report, based on rumors from the usual Scott27, that the BMW i8 Spyder has been greenlighted for production. The same discussion board even cites 2015 as a launch date.
But things might not be so perfect. Autocar UK reports that BMW i8 Spyder is presenting “major challenges” to engineer. A spokesman says that incorporating the carbonfiber-reinforced plastic bodyshell construction of the i8 into a convertible format was proving problematic: “The last architecture presented some fairly major challenges, to be able to produce a convertible in that format. The rigidity was hard to find with that particular architecture.”
Same source says no launch date has been set at this moment.
The Spyder Concept is a 2 seater, open top variant with the same architecture but with a lot more curb appeal. Among the most eye-catching features of the BMW i8 Concept Spyder are the upward-swivelling, windowless doors.
The i8 Concept Spyder is a plug-in hybrid powered by an eDrive drivetrain combining a high-performance electric motor and an internal combustion engine. The lithium-ion battery supplying the motor with power can be recharged in an extremely short space of time from any domestic power socket. Together, the car’s minimized weight, low center of gravity and finely judged balance, coupled with a combined system output of up to 354 horsepower.
Weighing just 3,600 lbs, the i8 Spyder runs to 100 km/h (62 mph) in five seconds and has a top speed of 250 km/h (155 mph). The fuel consumption is rated at 3 liter per 100 km or 78 MPG.
