The design of the upcoming 6-Series will certainly be taking cues from the current 7-Series but also be inspired by the CS Concept. The wide grill and headlamps providing for a mean-eyed cat look fitting to the performance model's identity.
Spy photographer reports that there has been a dry spell in spotting the upcoming 6-Series in testing (since spring) because BMW insiders say there have been some hiccups in the brand's development of the performance coupe/convertible.
According to insiders it appears they've settled upon a rigid roof coupe plus a canvas-top convertible version as indicated with shots of this 6-Series with a canvas only roof as confirmed by our spy photographer who checked inside and knocked on it with his hand.
BMW had some trouble deciding whether the 6-Series would come only as a single model convertible with a folding hardtop, or as two models - a rigid roof coupe and a convertible with a soft top. That would explain why previous prototypes were spotted with an ill-fitting canvas top laid over a supposed folding hard top.
