Theon Design Launches Theon R: Lightweight, 500HP Porsche 964

Introducing the Theon R, a 964-based Porsche 911 that redefines performance and engineering with over 500 horsepower from a 4.0-liter air-cooled flat-six.

Dubbed the Theon R, this latest creation is a tribute to Porsche’s most iconic, track-focused models. Limited to just 24 examples, it features a 4.0-liter flat-six engine that produces over 500 horsepower, making it the most powerful car Theon Design has ever built. The engine revs past 9,000 rpm and delivers 295 lb-ft of torque, providing a driving experience that’s both thrilling and visceral.

Theon has gone all-in on reducing weight, achieving a target of less than 1,000 kg by incorporating carbon fiber throughout the car. From body panels to structural components like the 4kg tubs bonded to the chassis, every part has been designed to save weight. Theon claims this not only improves the car’s rigidity but also enhances high-speed stability.

Inspired by Porsche’s Greatest Models

“Theon R is a tribute to Stuttgart’s most special, low-volume models, both past and present,” said Theon Design co-founder, Adam Hawley. “We’ve drawn inspiration from classic Porsches like the 911 S/T of the 1970s, the 964 RS Clubsport, and modern models like the 997.2 GT3 RS 4.0.” The result is a car that combines elements from these iconic vehicles, blended seamlessly with Theon’s own design and engineering expertise.

Advanced Aerodynamics and Lightweight Construction

Theon’s obsessive attention to detail is evident in the car’s aerodynamic design. The Theon R features a carbon fiber flat floor, a new front splitter, rear diffuser, and a prominent whale tail, all of which work together to improve downforce and on-track performance. These additions not only enhance stability at high speeds but also give the car a unique, aggressive stance.

Further weight reduction comes from carbon ceramic brakes and Minilite-style wheels, made primarily of lightweight magnesium. This setup ensures precise handling and reduces the overall mass, helping the car achieve an impressive power-to-weight ratio that surpasses any production 911.

Precision Handling with Motion Control Suspension

To complement its powerful engine, Theon has equipped the R with a sophisticated Motion Control Suspension. Featuring competition-bred dampers with independent high and low-speed compression and rebound adjustment, the suspension can be fine-tuned to suit various driving conditions. External reservoirs enhance performance, making the car adaptable for track days or winding mountain roads.

A Unique Collaboration and Premium Build Experience

The Theon R starts at £790,000 (excluding the donor car), and Theon Design promises a completely bespoke build experience for each customer. This 18-month process involves close collaboration with the client, ensuring that every Theon R is tailored to individual tastes and preferences. According to Hawley, "The R is without a doubt our fastest, most focused, and most ferocious model yet. It’s a special, rewarding car at any speed, and the ultimate expression of Theon’s OEM-grade design and engineering expertise."

A Nod to Air-Cooled Legacy

Theon Design has a deep appreciation for Porsche’s air-cooled legacy, and the R is no exception. By integrating elements like a drive-by-wire throttle and components from the 997 GT3 RS, they have created a car that delivers a driving experience reminiscent of a 1970s RSR race car, combined with modern-day precision and reliability.

Conclusion: The Ultimate Air-Cooled Porsche Experience

For enthusiasts of air-cooled Porsches, the Theon R represents the pinnacle of custom 964 builds. With its lightweight construction, cutting-edge engineering, and a powertrain that delivers over 500 horsepower, the R is set to be Theon Design’s most ambitious project yet. If you’ve got a passion for classic 911s and a budget to match, Theon Design offers a unique opportunity to create a car that’s truly one of a kind.

If you’re ready to embark on this bespoke journey, Theon Design is eager to make your vision a reality.
