We believe that a great manual gearbox is part of an even greater driving experience. Since our first car, every single Theon has been fitted with a lever and a clutch.

We offer two manual options – a restored and rebuilt five-speed from a 964, or a six-speed which is similar to one you would find in a 993 RS.

The choice is entirely yours.

Happy National Dog Day!

This is Teddy, who's part of the Theon Design team. Teddy is a nine-year-old Cockapoo and is one of our resident dogs, and he's a great member of the team.

Teddy can be found across the business. His main tasks are checking in on the team in the workshop, helping the office team, and of course, being one of the first to welcome visitors. He performs all of these flawlessly.

Out of the four seat options available when commissioning a Theon, the Recaro CS remains a favourite, combining exceptional support with long-distance comfort.

Trimmed in your choice of colours and materials, and available with integrated heating, it's a seat that's equally at home on a spirited drive or a cross-country tour.

At Theon Design, we offer three models, all with a shared philosophy.

Whether it's the timeless proportions of the Coupe, the open-air freedom of the Targa, or the uncompromising focus of the R, every Theon commission begins with the same objective – to create the finest interpretation of the air-cooled 911.

Each model offers a different character, but they're united by the same principles of thoughtful design, engineering excellence and a driving experience tailored to the individual behind the wheel.

Coupe – The purest expression of the classic 911

Targa – Open-top driving, without compromise

R – The ultimate air-cooled driving experience

Which one would you have?

The Theon workshop in full flow...

Our latest commission, a Bahama Yellow Coupe, is taking another step forward. The team can be seen completing the wiring installation and carefully fitting the carbon fibre interior inlays.

Stay tuned for more updates, direct from the 'shop floor.

Some of the most important engineering sits beneath the surface.

Our bespoke independent throttle bodies, developed with Jenvey in the UK, help the engine breathe more freely to produce over 100 bhp per litre. In the engine itself, custom low-silicon aerospace-grade aluminium pistons allow our naturally aspirated 4.0-litre flat-six to deliver a 12:1 compression ratio.

Individually, they're small pieces of a much bigger picture. Together, they help create an engine that's as rewarding to use on the road as it is impressive on paper.
