Roding have officially unveiled details of the Roding Roadster 23 ahead of the 2012 Geneva Motor Show where it will be displayed to the public for the first time. Roding are a German company presenting a production-ready sports car for the first time. Development for the Roding Roadster began back in May 2007 and became public knowledge after a concept was displayed at Frankfurt in 2009. Since then, the engineers have been fine tuning the car at their workshop in Roding, Germany near the Czech Republic border.
As the name suggests, only 23 of these cars will be built. Each will be a mid-engine sports car with a carbon-fiber chassis and a BMW in-line 3.0 liter six-cylinder turbocharged engine. Each will develop a peak output of 320 horsepower at 5,800rpm and 450Nm of torque between 1,300 – 4,500rpm. The key ingredient will be the 950kg target weight. According to CarAdvice, this makes 0-100km/h possible in 3.9 seconds with a top speed of 285km/h. Clearly this project conforms to the old school principles of modest power, low weight!
Roding believe it is also capable of 1.4g at 115km/h. Underneath sits a carbon fiber reinforced plastic (CFRP) chassis, while the front and rear subframes are aluminum and carbon hybrid structures. Compression rates for the suspension can be adjusted by the driver, as can be the ground clearance, toe and camber and front and rear anti-roll bars. This makes the chassis both extremely light and very stiff.
The transmission is a six-speed manual with a limited slip differential and a fourty percent lock-up effect using a TORSEN system. Brakes are four-pots up front on 328mm floating and grooved discs, while the rears are two-pot. The 18 inch alloy wheels are fitted with 225/40 series tyres up front and 255/35 series tyres at the rear, Toyo Proxes R888’s can be fitted as an option.
Each car is handmade and each car will get a two-colour exterior in red and carbon together with a black and beige leather interior. Lightweight Recaro racing seats with a four-point safety belt, an Alpine multi-media system with 6.1-inch touch screen, a GPS recorder with lap timer and a stopwatch have all been fitted.
