A modern take on a classic
While Singer pioneered the current wave of Porsche 911 restomods, a number of other firms have emerged in recent years to offer their own modern interpretations of classic 911s. One of the most well-known British companies doing this is Theon Design, and their latest project, which took over 18 months to complete, may be their most impressive yet.
The heart of the car
Without a doubt, the engine is the car’s main attraction. It’s an air-cooled, naturally aspirated, 3.8-liter boxer six-cylinder engine with individual throttle bodies that produces 407 hp at 7,600 rpm and 293 lb-ft (397 Nm) of torque. While the 4.0-liter engine in the new 911 GT3 has a 100 hp advantage, the Theon weighs just 1,150 kg, 312 kg less than the GT3. It’s clear that it should be a real pleasure to drive.
Additional technical features
Theon Design has fitted the car with an adjustable exhaust system that allows it to run quietly in the city or roar loudly on the open road. Power is sent to the rear wheels via a five-speed manual transmission.
The mechanicals of the car have many more interesting features. It is equipped with a semi-active TracTive suspension, designed for the worst roads in the UK, and even has a lift system, ideal for overcoming steep driveways and speed bumps. The car also received brakes from the 993 generation Porsche 911 Carrera RS and mounted on custom 18-inch wheels with Michelin Pilot Sport tires.
Body and interior upgrades
As with other Theon Design projects, the base car was stripped down to bare metal panels and the body structure was reinforced with new welds. It was then fitted with lightweight carbon fiber body parts painted in Ice Green Metallic, with accents in polished Eclipse chrome.
The interior is as much a work of art as the exterior. Inside, Recaro CS seats with carbon-fibre backrests, grey Alcantara, custom-made instruments and a hidden Alpine head unit with six Focal speakers are fitted. 
The cost of exclusivity
A car like this from Theon doesn’t come cheap. In fact, their designs start at £420,000 for coupés like this, and that doesn’t include the cost of the base car.
The Porsche 911 restomod market continues to expand, demonstrating that the demand for classic cars with modern technology remains high. Such projects not only preserve the historical value of the models, but also raise the bar of quality and individualization, making them attractive to collectors and enthusiasts looking for unique solutions combining retro design with modern features.
