While the BMW i8 Coupe is heading into production, the convertible version has hit a snag or two. Autocar has learned from a BMW spokesperson that the i8 Spyder has presented "major challenges" in the engineering department. The problem is due to the carbon fiber-reinforced plastic construction that provides the rigidity and lightness for i8. If you take off the roof like on the i8 Spyder, it becomes very difficult to add rigidity to the shell.
"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," said a BMW spokesman.
The spokesman went onto say that there isn't a set time frame for the i8 Spyder. Earlier reports put the production date around late 2015.
