In the measured quiet of Deddington, Oxfordshire, Theon Design has introduced a new interpretation of the air-cooled Porsche 911 (964), a machine that feels less like a restoration and more like a carefully composed mechanical sculpture. It is a car built around a single guiding principle: refinement without erasure, evolution without noise.
At its heart sits a naturally aspirated 4.0-litre flat-six producing 421 bhp and 324 ft lbs of torque, a figure that places it firmly in modern performance territory while preserving the emotional cadence of a classic flat-six. Paired with a six-speed manual gearbox and rear-wheel drive, the engine is managed through a MoTeC ECU and drive-by-wire system that introduces selectable character modes, shifting the car’s personality from calm road usability to full-intensity engagement. In its most expressive setting, the system sharpens response, amplifies exhaust character, and unlocks the engine’s full voice with deliberate theatricality.
Despite its performance credentials, the defining statistic may be its weight. At just 1,146 kg wet, the car achieves a power-to-weight ratio that surpasses that of a current 992.2 GT3. This is not achieved through simplification, but through material intelligence, including a full carbon fibre body that retains the original 964’s proportions while refining its surfaces and reducing mass where it matters most. Even so, steel doors remain, preserving the familiar tactile resonance that anchors the car to its heritage.
The chassis is supported by TracTive semi-active suspension with five distinct settings, allowing the car to transition seamlessly between composed daily driving and sharper, more focused dynamics. A front axle lift system ensures practicality is not sacrificed in pursuit of performance, reinforcing the dual nature of the build as both usable machine and precision instrument.
Finished in Crayon Grey with Lizard Green accents, the exterior design relies on restraint rather than aggression. Smoked lighting elements and brushed Eclipse brightwork introduce a contemporary edge, while a Turbonite Porsche crest adds a subtle modern signature. Seventeen-inch wheels in Anthracite and Black sit with controlled presence, punctuated by RS brake calipers in Lizard Green that provide a deliberate flash of contrast.
Inside, the philosophy continues with a blend of carbon fibre structure and Liquorice leather trim, accented by Lizard Green stitching that threads continuity through the cabin. Recaro RS seats maintain a focused driving position, while machined aluminium details across switches, vents and inserts introduce a precise, engineered texture. The instrument cluster is uniquely configured, mirroring the exterior palette to reinforce cohesion between visual and mechanical identity.
Technology is integrated with restraint. An original Becker Mexico head unit is paired with a Hertz amplifier and six Focal speakers, supported by discreet modern conveniences such as wireless charging and hidden phone integration within a carbon fibre centre console. Nothing feels added for spectacle; everything feels justified by use.
Each Theon commission is the result of approximately 6,000 hours of development, shaped through close collaboration between client and studio. Rather than selecting from predefined options, owners influence everything from steering feel and suspension behaviour to engine response and overall character. The result is a vehicle that behaves less like a product and more like a tailored interpretation of driving intent.
Built in Oxfordshire within the heart of Motorsport Valley, Theon draws on expertise and suppliers more commonly associated with Formula One and aerospace industries. Carbon fibre components are produced using advanced motorsport techniques, while lightweight electrical systems enhance both reliability and performance. Production remains deliberately limited, with only six commissions scheduled for 2026, ensuring each build receives extensive attention and development time.
Priced from £430,000 excluding donor vehicle and associated costs, this latest 964 stands as a distilled expression of Theon’s philosophy. It is neither a nostalgic recreation nor a modern reinterpretation in the conventional sense, but a carefully balanced synthesis of both.
As founder Adam Hawley notes, the most successful Theon builds are those that avoid being tied to a single era. This commission embodies that idea fully, existing in a space defined by intent, material clarity and driving focus rather than time or trend.
