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.
The press release is available after the jump and be sure to check out our gallery below.

Mercedes-Benz SLR McLaren Roadster: An open-air adventure for all the senses
Stuttgart, May 04, 2007
Mercedes-Benz will in future also market its SLR McLaren super sports car in the form of a roadster with a top. In common with Formula 1 vehicles of today, it, too, will be made of carbon fibre, a material that will endow the vehicle with a very high degree of safety as well as extreme torsional stiffness at the same high level as the coupé version. This gives rise, in combination with the racing-type chassis, to outstanding ride characteristics.
The maximum speed of the new high-performance sports car, which is powered by an AMG V8 compressor engine delivering 460 kW/626 hp, is 332 km/h, therefore at the same high level as the coupé. Although, thanks to its fully retractable top, the Roadster offers undiluted open-air driving pleasure in the highest performance class, its occupants in no way lose out in terms of comfort or the vehicle's suitability for everyday use. Consequently, the new Roadster opens up a new dimension in refinement for open-top super sports cars.
Like the coupé version, the new Mercedes-Benz SLR McLaren Roadster once again unites the legend of the successful SLR racing models from the 1950s with the innovative technology of modern Formula 1 vehicles from the Vodafone-McLaren-Mercedes team. Typical stylistic elements, such as the arrow-shaped tip of the Formula 1 Silver Arrow, establish a visual link with the racing cars. The SLR leg-end of the 50s lives on stylistically in the distinctive lateral louvers, side pipes behind the front wheels and the wide-opening gullwing doors.
The new Roadster benefits technically from the many years of experience of Mercedes-Benz and its Formula 1 partner McLaren. Apart from two aluminium engine frames, its body is made entirely of carbon-fibre reinforced plastic (CFRP) materials, making the vehicle an exception among high-performance sports cars. Especially for the Roadster, complex carbon-fibre technology has been intelligently further developed for the monocoque chassis. The result is low weight, exemplary energy absorption and, therefore, extremely high occupant safety as well as a degree of torsional stiffness hitherto unattained in open-top vehicles. This leads to outstanding ride characteristics of the kind otherwise found only in closed-top super sports cars.
The puristic top is suitable for high speeds
The exceptional qualities of the Roadster are attributable also to the fully retractable top, which blends harmoniously into the flowing lines of the SLR McLaren. Its newly developed roof material, which is available in three different colours, not only guarantees complete suitability for everyday use in all weathers, but also endows the high-performance sports car with characteristics that are exception-ally unusual in a roadster. For example, at 332 km/h, the maximum speed is at the high level of the coupé version. Conversation is still possible at well over 200 km/h on open-air journeys thanks to the favourable aeroacoustics.
The roof opens and closes semi-automatically in less than ten seconds, thereby combining the desire for convenience with the puristic character of the roadster. To open, the roof merely needs to be unlocked from the windscreen frame and be briefly raised, after which it folds away electrically. Since an aluminium cover is integrated into its front section, the roof elegantly closes off the top when re-tracted.
Sophisticated aerodynamics and racing-type chassis
In the wind tunnel, the Roadster has been optimised for high speeds with regard to handling, aeroacoustics and aerodynamics. It likewise employs the aerodynamic concept already known from the coupé version, featuring an airbrake integrated into the access lid and a diffusor in the rear bumper to provide increased downforce on the rear axle.
The open two-seater is equipped with a racing-type chassis featuring high-performance carbon-ceramic brake discs, thereby setting extremely high stan-dards. Its front-mid-engine provides for optimum weight distribution. With 460 kW/626 hp and a maximum torque of 780 Nm, the AMG V8 compressor engine, which is coupled to an AMG Speedshift R five-speed automatic transmission, accelerates the Roadster from zero to 100 km/h in 3.8 seconds.
Unique safety and exclusive fittings
A high degree of safety is ensured by unique carbon-fibre crash elements, steel-reinforced A-pillars and two fixed roll-over bars. The comprehensive specification also features adaptive airbags, knee and side airbags as well as seat belt tensioners and a tyre-pressure monitoring system.
The exclusive standard equipment includes semi-aniline-leather-upholstered carbon-fibre bucket seats which can be individually adapted to the driver and front passenger by means of differently sized seat pads; dual-zone automatic air-conditioning; a high-quality BOSE premium sound system; a multifunction sport steering wheel with gear-change paddles, and a navigation system with integral radio and CD player.
The new Mercedes-Benz SLR Roadster, like the coupé, is produced at McLaren's Formula 1 factory in Woking, England, in accordance with stringent Mercedes-Benz quality criteria and will be available as from September 2007.
