Geneva 2011: Carlsson C25 Royale is a Mercedes-Benz SL65 AMG in Disguise

Carlsson showed up at the Geneva Salon with a new version of its C25 supercar dubbed Royale. Based on the Mercedes-Benz SL 65 AMG, the heavily customized coupe with the fixed rooftop will be built in a limited run of 25 units. Company officials said six vehicles have already been sold and will be delivered to the customers in 2011. According to Carlsson, each C25 Royale takes six months from order to delivery.

Compared to the Mercedes SL65 AMG coupe-cabriolet, the C25 Royale is 180 kilograms lighter, thanks to the extensive use of carbon fiber, which is found on the hood and the fixed roof. This contributes to a lower center of gravity, in addition to the revision of the weight distribution, both aimed at offering improved handling.

Other weight-saving measures include the fitting of a full ceramic brake system, which is 50 percent lighter than on the SL 65 AMG. The German sports car also features a C-Tronic Suspension system developed by Carlsson, which detects road conditions and driving style and acts accordingly. For instance, on bad roads, the car is raised to offer better ride comfort.

At the heart of the C25 Royale is the biturbo V12-engine, tuned to deliver753 horsepower and 1,320 Nm of torque (973 lb-ft), which is electronically limited to 1,150 Nm (848 lb-ft). These impressive figures allow the C25 Royale to go from 0 to 100 km/h in 3,7 seconds and reach a top speed of 352 km/h (219 mph).

The custom exterior styling is matched to a bespoke interior with Carlsson offering buyers a variety of choices in features and materials.

U Spy: 2012 Mercedes-Benz SL Roadster Convoy Scooped in Spain

Carscoop reader Frank Jonas hit the Mercedes-Benz jackpot when travelling in Spain last week, he stumbled upon a convoy of camo'ed SL prototypes, which were accompanied by several other vehicles with the star on their bonnet including an example of the current generation of the German firm's hardtop roadster model.

"On my trip to the south of Spain last week I had the opportunity to take some pictures of a heavily camouflaged Mercedes-Benz Coupe/Cabriolet, most probably the next SL," Frank told Carscoop.

Although Mercedes has done its best to disguise the SL by covering it in heavy cladding, we can see that the new generation model keeps its predecessor's two-piece folding hard top, while the styling is expected to adopt the German firm's more "artsy" design philosophy as seen on the latest CLS and recent concept models such as the F800 Style, along with a more in-your-face front grille.

Being that the 2012 SL was developed alongside the SLS Gullwing, the two models are likely to share certain key components such as the suspension bits and electrical systems.

Information regarding the engine range remains scarce, but buyers should expect a entry-level V6 and the usual lineup of V8 units including Merc's newly developed 5.5-liter bi-turbo V8 for the AMG model, and possibly, an upgraded V12 for the flagship version.

Hat tip to Frank for the scoop!

MR Car Design Tunes up the Pre-Facelift Mercedes-Benz SL 65 AMG

The pre-facelift Mercedes-Benz SL 65 AMG is the object of MR Car Design's latest tuning program. The exterior kit for the hardtop roadster model includes a lightweight carbon fiber hood from Kicherer, smoked up turn signals all around and the rear diffuser from the newer 2009MY SL 65 AMG. A set of shiny 20-inch alloy wheels from Carlsson and custom-made Black Series gauge dials inside complete the styling package.

To improve performance, the Germany-based tuning firm optimized the bi-turbocharged V12 engine's ECU and added a custom sports exhaust system, which help lift output by 80HP for a total of 692-horses. The removal of the electronic speed limiter and the addition of an electronic module that lower the roadster model's ride height by 30 mm round off the changes.

A Short History of the 1955 Mercedes-Benz 190 SL Roadster

It might not be a widely known fact, but strictly speaking, the Mercedes SLK roadster has a 55-year-old pedigree. Allow us to explain. When the German automaker presented the first SLK concept study in 1994, it was continuing the firm's small roadster tradition which stated back in 1955 with the 190 SL.

The latter was the brainchild of Maximilian Edwin Hoffman, an enterprising American with Austrian roots who imported European cars to the USA. In 1953, after seeing the potential of a more affordable sports car than the 300 SL, he urged Daimler-Benz executives to build one.

The 190 SL was unveiled on February 6, 1954, in New York, alongside the 300 SL “gullwing”. It was designed more as an elegant two-seater touring model than a purebred sports car. It took engineers only five months to develop the open-top car, which used a shortened frame floor assembly from the Mercedes 180 (W120), combined with a single-joint swing axle sourced from the 220 (W180). The front suspension also came from the 180 model.

Under the bonnet, the 190 SL had a newly developed 105HP 1.9-liter four-cylinder engine with an overhead camshaft. Performance was good for the era, as the roadster could complete the 0-to-100 km/h (0-62 mph) sprint in 14 seconds and reach a top speed of over 170 km/h (106 mph).

Series production began in May 1955 and the 190 SL was available as a soft-top roadster as well as a coupe with removable hardtop, with or without the soft-top as an option.

Between May 1955 and February 1963, 25,881 units rolled off the assembly lines in Sindelfingen, well above the initial estimates.
