With this venture, Studio Torino wanted to promote the production of handcrafted off-sets combined with prestigious high performance mechanics and to share with friends and clients their passion for automobiles.

The RK Spyder is the first example of what they consider fine sports cars. The RK Spyder was produced in a limited number of not over 49 specimens. Details and mechanics were personalized as requested by the client. This first limited edition was preceded by two prototypes numbered Prototype 1/2 and Prototype 2/2.

This first project presented by Studio Torino was created in collaboration with Alois Ruf of Ruf Automobiles who developed the mechanical, performance and certification aspects. For this reason, the RK Spyder carries the Studio Torino name plate on the sides and the Ruf logo on the motor and on the hood.

Like the first modern sports cars of the 1950"s, the RK Spyder crafted by Studio Torino is topless. Naturally, it is a roadster. It is understated and essential, never brash and yet aggressive in a minimalist manner. It is tailored to the pilot and co-pilot like an haute-couture dress. It is powerful, but not excessively. It's power plant guarantees approx. 420 bhp (305 kW), but mostly a very high torque at any RPM. Top speed is approximately 285 km/h (177 mph).

Leading industry partners and service providers have designed, manufactured and provided for the first time, purposely and for this off-set model only, technologically advanced components such as alloy wheels, tires, braking systems, paints, luxury leather interiors and carbon-fiber seats.

Body and Paint

The body of the RK Spyder, including the bumpers, is in part a modification and in part an ex novo construction. All that is left of the original body is the front left fender. The materials used for the custom body are aluminum sheets, steel sheets and carbon fibers. One of the fundamental characteristics of the car, owing to Alfredo Stola's know-how, is the painting process which aims to research the best light reflection effects on the body. The painting process lasts ten days. It begins with a complete manual re-working of the surface and the application of primers followed by five coats of paint at 80º with intense depth PPG car refinishing products.

After this first painting phase is completed, following the RK Spyder's aesthetic philosophy, a second color is used to trace two lines on the rear fenders. A third color is employed to paint the name plate on the rear hood. At the end of this process, a transparent enamel is sprayed followed by meticulous water sanding and hand polishing using abrasive paste and polish.

Three "jewels" of the project cannot go unnoticed: the fuel tank lid, the third brake lights and the muffler. Milled from forged aluminum and hand finished, they have been manufactured following an exclusive design. Due to the lowering of the windshield frame and the two lateral windows, these have been custom built by Isoclima, a leading Italian firm. Both the certification code and the Studio Torino logo have been silk-screened onto the glass. For safety reasons, the original steel tubes inserted in the struts have not been modified.

Every Studio Torino name plate has been hand made one by one by Ragni, an historic Turin company. Name plates have also been placed above the side air intakes of the rear fenders and on the wheel center caps.


The wheels are another aesthetic singularity of the RK Spyder. The rims have been designed and manufactured by Toora. Exclusively developed for this project, they are made of forged aluminum, composed of three pieces and have five spokes. Fulda has specifically designed and produced the tires for Studio Torino from their Carat Exelero series. All is completed by a specific and powerful Brembo braking system with aluminum brackets and cast iron discs.


Since the car is topless, special attention has been focused on the aesthetics of the interior. The lower part of the dashboard, the steering wheel, the door panels, and the center console have been hand upholstered with luxury leather by Poltrona Frau.

The seats have been designed and built by Toora and appear for the first time on the RK Spyder. The electrically reclining seats are made of carbon fiber and are hand upholstered using lavishly innovative Poltrona Frau leather. The leather used for the seats has been specially engineered for a topless sports car: it reflects sunrays and maintains a constant temperature even after having been exposed to the sun for long periods of time.

Also by Poltrona Frau is the newly designed wall that separates the engine from the interior in black leather with a diamond design and double stitching in a contrasting color.

The brake and clutch pedals have been personalized. They are made of aluminum and have a rubber anti-slip pad bearing the Studio Torino logo. The rollbar, which has been repainted, has been left original as well as the safety belts. An elegant name plate on the console carries the serial number of the car.

Choice of Engine

As for the choice of the "heart" of the Spyder by Studio Torino, the client has the option of choosing the type of engine preferred. According to his needs, the client may choose between an aspirated engine, an injection engine, a Kompressor engine or a turbo engine. The first prototype car carries a RUF 3.8 liter Kompressor engine.

The basis of this Kompressor engine is a centrifugal compressor with a planetary gearbox -a kind of mechanical turbo charger, which is driven mechanically by a Poly-Rip belt. The maximum boost is 0.5 bar. The engine has a RUF designed intake manifold, modified injectors, sports catalytic converters and a modified electronic engine management system. The water-cooled charge cooler has a cooling water circuit with an electric water pump from the water cooler in the front spoiler.

The supercharged 3.8 liter engine of the RK Spyder provides a 420 bhp (305 kW) at 7000 rpm and 450 Nm torque at 5500 rpm. The acceleration from 0 - 100 km/h (0 - 62 mph) of the 3.8 liter RK Spyder with a RUF Kompressor Engine takes only 4.5 sec., from 0 - 200 km/h (0 - 125 mph) only 13.8 sec. The maximum speed is 285 km/h (177 mph).
