Roding Roadster 23 details released in Geneva [video]

First time specialty sports car maker from Germany, Roding Automobile, revealed their Roding Roadster two seat mid-engine sports car at the Geneva Motor Show this past week.

The uniquely styled mid-engine Roadster sports car features a carbon-fiber chassis allowing the vehicle to have a weight of only 950kg (2,094lbs). This lightweight body combined with a BMW in-line 3.0-liter six-cylinder turbo engine producing 320HP (235kW / 325bhp) gives a power to weight ratio of less than 3 kg/HP and renders the 0-100km/h sprint in 3.9 seconds while 80-120km/h (in fifth fear) takes 4.0 seconds. Even more impressive is its lateral acceleration figure of 1.4g at 115km/h (71mph). All of this is achieved while consuming just 8.2-liters of fuel per 100km (34.4 mpg imp).

The first cars to be produced are a special edition, limited run of 23 Roadsters, hence the name. These edition models feature an exclusive exterior design with all visible carbon parts like the hood, rear, chassis, doors and roof unpainted and the rest of the body in any custom color the customer wants. It also includes factory installed racing components.

"The Roding shows how it is possible to make ideal use of light-weight potentials in the vehicle with the fiber bond-appropriate design. The technologies used clear the way for the structural use of fiber bond materials in the major series", explains Dr. Klaus Drechsler (Professor, Technical University Munich), one of the most renowned scientists and technology specialists in the area of CFRP.

Full details and specs in the press release below.

Passion meets perfection

With a design that shows character and temperament and uncompromisingly high performance, this distinctive vehicle concept sets new standards in the roadster sports car segment. It's supreme agility and powerful performance allow you to experience the art of German engineering - firsthand. Because every Roding is manufactured by hand in a modern production process and can be customized to the smallest detail upon request, each car becomes a very personal item for it's owner.

It is time to travel beyond the beaten path and experience true, unfiltered driving pleasure. Experience the Roding, a Roadster created by people with passion for performance automobiles.

Performance made easy

The Roding is a two seat mid-engine sports car with a carbon fiber chassis and a powerful BMW 6 cylinder turbo charged engine. Maximum performance and driving dynamics are achieved through consequent lightweight construction, and a state of the art six cylinder turbo charged engine.

The Roding Roadster is powered by a BMW high-efficiency six in line turbo engine. The engine generates 320 HP and has a torque of 450 Newton meters. The centre engine is installed in transverse configuration in relation to the vehicle longitudinal axis. The lightweight concept with a vehicle weight of 950 kg in conjunction with the powerful engine give the Roding a power to weight ratio of less than 3 kg/HP. This allows not only spectacular acceleration values but also high curve speeds, which is expressed in a curve acceleration of 1.4 g.

Shifting is accomplished with a manual 6-Speed transmission, which transfers the power to an limited slip differential with a locking effect of up to 40%. This divides the engine power between the rear wheels, increasing the available traction while accelerating.

In combination with a sporty mixed tire compound, which can also optionally be ordered as a semi-slick variation, the rear axle thereby always remains easy to control, despite the high engine performance - even with the desired drift. In addition, the shocks and the fully independent suspension with double wishbones can be adapted to the purpose - road or race track - and individually adjusted by the driver.

23 sophistication in driving

The first cars to be produced are a special edition, limited run of 23 Roadsters, hence the name "Roding Roadster 23".These edition models feature an exclusive exterior design with all visible carbon parts like the hood, rear, chassis, doors and roof unpainted and the rest of the body in any custom paint color the customer wishes. It also includes factory installed racing components. This weight reduced Roadster was designed for the racetrack, but is also completely suited for daily use.

Perfomance through weight reduction

The essence of lightweight construction is the concentration on only what is necessary and the application of modern materials. The main chassis cell is manufactured of carbon fiber reinforced plastic (CFRP), while the front and rear subframes are aluminum-CFRP hybrid structures. This material has been proven in its application in aerospace and formula one due to its low weight and high stiffness. Characteristics that play a large role in an open roadster like the Roding, since stiffness and light weight are the foundation for precise handling and impressive road performance.

Another core element of the main chassis is the integration of the required functions. For instance, the seat mounting points are integrated in the form making adapter brackets unnecessary.

"The Roding shows how it is possible to make ideal use of light-weight potentials in the vehicle with the fiber bond-appropriate design. The technologies used clear the way for the structural use of fiber bond materials in the major series", explains Dr. Klaus Drechsler (Professor, Technical University Munich), one of the most renowned scientists and technology specialists in the area of CFRP.

With performance figures like those, for me it only has to look good ENOUGH, and I think it does indeed look good enough (although it would look better with painted doors IMO). This ought to be a cracking little car!

Reminds me of a Lego version of the R8--but I like it. Love the Power to weight ratio, and 1.4g on the skidpad is mind blowing. Looks like a winner to me.

The name should be "R8 FUBAR".
