We've seen it in spy shots, but now we get to officially see the newest hotness from Mercedes Benz: the SLR McLaren Roadster.

In an effort to inject some more life into the slow-selling Mercedes/McLaren halo, engineers lopped off the roof to make one of the fastest open-air motoring experiences this side of a sportbike. Naturally, they just didn't whip out the sawsall and go to town. Instead, the new roof is made from that most delectable of materials – carbon fiber. The retractable roof isn't the only thing that gets the C.F. reinforced plastic treatment, as all but two of the body frames, made of aluminum, utilize the exotic compound. Lightweight and untwistable strength are the features du jour.

As for motivation, the SLR Roadster doesn't benefit from the 722's 650 HP V8. Instead, it has to make due with the standard SLR's 617 HP supercharged mill, allowing the drop top to hit its velocity climax of 207 MPH – blow drying has never been made easier, or more fun.

Those willing to drop the coin on the McMerc convertible will be able to choose from three different roof colors, and according to Mercedes, two passengers can have a comfortable conversation at 125 MPH with the top down. Before doing so, the occupants will have to manually (for shame!) unlatch the roof, push upwards, then let the motor bring the roof down into its home – and underneath an aluminum cover – in a scant 10 seconds.

Only 1,000 of the roof deprived, a-pillar reinforced, and rollover hoop equipped SLR Roadsters will be available and customers will begin taking delivery this September. Pricing: £350 large.

A full gallery is available below and Mercedes' press release is posted after the jump.

We're still waiting for Mercedes to get its act together and put up images on its media site.
