The world of Porsche restomods is hardly short on impressive machinery, but every now and then something comes along that reminds you why enthusiasts can't get enough of reimagined air-cooled 911s. The latest creation from UK-based Theon Design is one such example. Based on the Porsche 964-generation 911, this bespoke commission combines classic styling with modern engineering, resulting in a machine that delivers the analogue charm of an old-school 911 while packing the performance of something considerably newer.
Lightweight philosophy
At the heart of this build is an extensive weight-saving programme. Theon has fitted a full carbonfibre body, helping keep the car's wet weight down to just 1146kg. Interestingly, the company has chosen to retain the original steel doors rather than replacing them with carbonfibre units. According to Theon, this decision preserves the familiar feel and tactility of a classic 911, maintaining a connection to the donor car despite the extensive modifications elsewhere. The result is a remarkably light sports car that tips the scales at hundreds of kilograms less than a modern Porsche 911.
Naturally aspirated power
Power comes from a naturally aspirated 4.0-litre flat-six engine producing 421bhp and 439Nm of torque. That's sent exclusively to the rear wheels through a six-speed manual gearbox, exactly as many Porsche purists would want. The engine management system is controlled by a MoTeC ECU and features selectable drive modes that alter the car's character depending on the situation. Drivers can switch between Town, Road and Race settings, while a dedicated 'Raucous' mode unlocks the engine's full personality by sharpening responses, raising the rear spoiler and amplifying the exhaust note. Combined with the low kerb weight, Theon claims the car boasts a power-to-weight ratio that surpasses that of the latest Porsche 992.2 GT3.
Modern chassis, classic feel
While the performance figures are impressive, Theon's focus extends beyond outright speed. The car is equipped with TracTive semi-active suspension featuring five different settings, allowing it to transition from comfortable road car to focused driver's machine. A front axle lift system has also been incorporated, making the low-slung 911 more usable in everyday situations. What makes the package particularly interesting is the level of personalisation involved. Rather than applying a standard setup to every build, Theon calibrates each car specifically for its owner. Steering feel, throttle response, suspension behaviour and overall vehicle character are tailored to individual preferences.
Bespoke inside and out
This particular commission is finished in Crayon Grey with contrasting Lizard Green accents. The subtle exterior colour is complemented by smoked lighting elements, bespoke brightwork details and 17-inch wheels finished in Anthracite and Black. Inside, the cabin follows the same restrained approach. carbonfibre trim is paired with Liquorice leather upholstery and subtle green stitching. Recaro RS seats, bespoke instrument dials and machined aluminium details complete the package, while modern conveniences such as wireless charging are discreetly integrated into the interior. Theon says each commission requires around 6000 hours to complete and works closely with every client throughout the process.
Production remains extremely limited. Only six Theon commissions will be delivered globally during 2026, with prices starting at £430,000 (that's ₹4 crore) before the cost of the donor car, shipping and local taxes. Expensive? Absolutely. But when the result is a bespoke, carbon-bodied, manual Porsche 911 with more power-to-weight than a GT3, it's easy to see the appeal.
