The very ambitious aftermarket specialists at Carlsson their very first specifically built hill climbing racer. Carlsson’s new race car is based on the Mercedes-Benz SLK and is scheduled to premiere at the 2013 Geneva motor show in March.

The new Carlsson Mercedes SLK will compete in several events this year in the E1 category. The Carlsson SLK 340 JUDD was built from scratch by Carlsson on a body shell and weighs in at just 780 kg (1,719 lbs). In order to reach such a low weight, Carlsson built the body of their new SLK from carbon fiber. And in order to keep the carbon body planted, all the body parts have been tested in the wind tunnel to ensure maximum downforce. The car’s large rear wing and diffuser was also given special attention to give as much traction to the SLK as possible.

The Carlsson SLK 340 JUDD is powered by a 3.4-liter V8 engine that puts out 610 hp and 430 Nm of torque. The engine, which weighs 120 kg, is mated to a Hewland transmission with steering wheel mounted paddle shifters. The Carlsson Mercedes SLK rides on a 3-way adjustable KW competition suspension, BBS racing wheels and AVON tires. The car comes with Fibreworks racing seats and a full roll cage.

World premiere in Geneva: Carlsson presents race car based on SLK

Gut Wiesenhof, Germany, January 23, 2013

The Carlsson SLK 340 celebrates its world premiere at the Geneva Motor Show. This is an absolutely unique race car developed using advanced construction techniques. Entries are planned at national and international hill climb races in the E1 category. Project manager Reto Meisel (42), project manager Martin Burmeister and their Swiss team Meisel Motorsport want to continue the sporting successes of the 190 EVO with this powerhouse and blow away the international competition.

The newcomer in international motorsport captivates with an abundance of modifications. The engineers have subjected the car, which was built from scratch on a body shell, to a comprehensive weight-loss regime. At the same time, it also received a power boost. Thanks to the use of the most modern materials, the Carlsson SLK 340 JUDD weighs in at only 780 kg on the scale. To accomplish this, an ultra lightweight body kit made of carbon was used. The aerodynamic components have been tested extensively, even in a wind tunnel, to connect a spectacular look with a perfect downforce. A closed underbody will further optimize the air resistance of the hill climb race car. Despite extensive changes, the SLK in its racing suit with its powerful rear wing looks extremely stylish. "We developed the design over a long period of time and with lots of feeling. We are proud of the awesome look. As an engineer, it is a pleasure to contribute to such a project, and we can show everything that is technically possible in the vehicle in cooperation with Carlsson", says Dipl.-Ing. (FH) Markus Schuster, Managing Director of Carlsson Germany.

The heart of the racer is the 3.4-liter V8 engine. The engine develops a fabulous 610 hp. It has a maximum torque of 430 Newton meters, while weighing in at no more than 120 kilograms. The racing team relies on a Hewland transmission with a paddle shift.

A 3-way adjustable KW competition suspension ensures optimum road holding for the race car on BBS racing wheels (10x18 front, 13x18 rear) and AVON tires. The brake system of ultralight materials saves additional weight. Maximum support and maximum safety are guaranteed by newly developed racing seats from Fibreworks.

Safety first! In accordance with the regulations, a complex safety cage has been installed which meets all relevant international requirements. A total of 1800 hours of development work has been invested up to the premiere. In this respect it is no wonder that the designers speak proudly of a true masterpiece. Carlsson racing seats ensure optimum lateral support.

Reto Meisel, team leader and driver, has been active in motorsports since 1989: "I'm really looking forward to the challenge of accompanying and coordinating a race car, which started out as a vision on a piece of white paper, right from the beginning. There has never been a race touring car with such extreme performance and technical features."

The list of sporting achievements of the experienced Swiss driver is considerably long. The racer dominated, among others, the German Mountain Championship from 1999 to 2001. He triumphed at the 2002 Swiss Mountain Coupe, and in 2007 and 2009 he became German Touring Car Hill Climb Champion. "Another goal is to participate with the Carlsson SLK 340 at the legendary Pikes Peak race in Colorado, USA. "It will be an honor for us to compete internationally with the factory teams of Hyundai and Suzuki," continued Reto Meisel.
