A Closer Look at the Theon R: Ultimate Air-Cooled Porsche

Theon R by Theon Design is the ultimate evolution of the air-cooled Porsche 911. This follow-up look delves into the obsessive craftsmanship, lightweight engineering, and exhilarating driving dynamics that make the R unique. Each component reflects Theon Design’s expertise in refining the classic 964 platform for pure analogue thrills.

Obsessive Lightweighting by Theon Design

The R weighs less than 1000kg ‘wet,’ achieved through an extensive carbon fibre program developed with an F1 composites supplier. Doors, body panels, and interior components are all crafted from ultra-strong carbon fibre. Seam welding and bonded carbon tubs reinforce torsional rigidity without adding weight, delivering precision handling and a visceral connection to the road.

500+ BHP Air-Cooled Flat-Six

Powering the Theon R is a 4.0-liter, 24-valve air-cooled flat-six, producing over 500bhp and 400ft-lb of torque. The engine revs past 9,000 rpm and is paired with a short-throw six-speed manual and Wavetrac limited-slip differential. With a power-to-weight ratio exceeding 500bhp per ton, the R accelerates to 60mph in just 3 seconds and 100mph in 6.5 seconds, offering unmatched analogue performance.

Advanced Motion Control Suspension

Theon Design fitted the R with a bespoke Motion Control Suspension (MCS) system. Its adjustable MCS 3W dampers allow the car to conquer twisty mountain passes or become a track-ready weapon with minimal setup. The R’s dynamic abilities reflect Theon Design’s mastery of balancing extreme performance with precise, responsive handling.

Carbon Fibre Body and Aerodynamics

The R’s lightweight carbon fibre body incorporates a fixed rear wing, front splitter, rear diffuser, flat floor, and aero roof channel. Every panel was CAD-modeled for perfect fit and rigidity. These aerodynamic features enhance high-speed stability while maintaining the classic 964 silhouette.

Driver-Focused Cockpit

Inside, Theon Design emphasized a pure, analogue driving experience. Minimalist yet functional, the cabin blends carbon fibre, racing-grade composites, and a three-spoke steering wheel. Analogue gauges, shift paddles, and precise controls immerse the driver fully, ensuring that engagement is never compromised.

Brakes and Chassis Excellence

High-performance ceramic Brembo brakes provide incredible stopping power. The steel monocoque chassis, reinforced with carbon tubs and RS seam welding, forms a light yet strong foundation. Every detail is engineered to handle extreme power while keeping overall weight low.

Summary

Theon R by Theon Design is a rare example of analogue Porsche perfection. Lightweight, 500+ BHP, and meticulously engineered, it offers visceral thrills while remaining precise and controllable. This closer look highlights the carbon fibre construction, air-cooled flat-six, Motion Control Suspension, and driver-focused engineering that define the R.
