They have got to be kidding. Another SLR derivative? Before the Mercedes-McLaren supercar speeds off into the horizon, it will have spawned no less than six different versions - including the original coupe, the Roadster, 722, 722 GT, the upcoming "Speedster", and this latest variant - if the latest reports are to be believed. We would have thought that the spied Speedster version would have been the last, but then spy shots surface of what appears to be a 722 Roadster.
This undisguised vehicle carries all the visual cues of the 722 edition coupe: the dark grey 19" forged alloys hiding red brake calipers over oversized discs, plus the carbon fiber lip spoiler and darkened taillight clusters. The convertible can be expected to carry the same 650-hp supercharged V8 as the 722 coupe, only with the nifty hard-soft top from the roadster. By the state of readiness evident from these spy shots, we'd venture that the 722 Roadster will appear before the Speedster. And we trust that will be the end of the SLR... until someone says otherwise, of course.
