2026 Theon Design GBR008
By Lorenzo Bianchi November 14, 2026
The 2026 Theon GBR008 is based on the Porsche 911 (964), featuring carbon fibre bodywork, retained steel doors and a bespoke Crayon Grey exterior with Lizard Green accents.
A naturally aspirated 4.0-litre flat-six produces 421 bhp and 324 lb-ft of torque, paired with a six-speed manual gearbox, rear-wheel drive and TracTive semi-active suspension.
The car weighs 1,146 kg wet and features a handcrafted interior. Theon will deliver just six commissions worldwide in 2026, with prices starting at £430,000.
2026 Theon GBR008 Brings 421 BHP to the Porsche 964
The 2026 Theon GBR008 is another individually commissioned Porsche 911 from British specialist Theon Design, revealed on June 3, 2026.
Based on the 964-generation 911, the car has been extensively re-engineered around a naturally aspirated 4.0-litre engine, lightweight carbon fibre construction and a six-speed manual gearbox.
The owner worked closely with Theon throughout development, influencing everything from the exterior colours to the way the car responds on the road.
The result is a rear-wheel-drive 911 weighing 1,146 kg wet, with a power-to-weight ratio exceeding that of the Porsche 992.2 GT3.
Crayon Grey Bodywork With Lizard Green Accents
The exterior uses a full carbon fibre body finished in Crayon Grey, contrasted by carefully placed Lizard Green detailing.
Smoked front and rear light lenses give the classic 911 design a darker appearance, while brushed Eclipse brightwork replaces the usual polished treatment.
A matching Turbonite Porsche bonnet crest completes the exterior detailing.
Theon has retained the original-style steel doors, preserving the familiar closing feel of an older 911 despite the extensive use of lightweight materials elsewhere.
Lightweight Construction and 17 Inch Wheels
The GBR008 rides on 17-inch wheels finished in Anthracite and Black.
Behind them sit RS brake calipers painted Lizard Green, introducing another contrast against the relatively restrained exterior.
At 1,146 kg, the completed car combines lightweight bodywork with a power-to-weight figure above the current 992.2 GT3.
TracTive semi-active suspension provides five adjustment settings, allowing the driver to switch between more compliant road behaviour and firmer performance-oriented responses.
A front axle lift system adds another useful feature for everyday driving.
Liquorice Leather Interior With Recaro RS Seats
Inside, the cabin follows the exterior's colour scheme.
Carbon fibre panels are hand-trimmed in Liquorice leather, with Lizard Green stitching across the interior.
Recaro RS seats receive matching detailing, while aluminium footboards, machined door handles and metal dashboard inserts introduce contrasting finishes.
The instruments feature bespoke Crayon Grey and Lizard Green details.
An original Becker Mexico head unit works with a Hertz amplifier and six Focal speakers. Wireless charging and a discreet phone extension are integrated into the carbon fibre centre console.
Naturally Aspirated 4.0 Litre Flat Six
The air-cooled 4.0-litre flat-six produces 421 bhp and 324 lb-ft of torque.
It uses MoTeC electronic management, drive-by-wire throttle control and carbon-infused intake trumpets.
Selectable driving modes range from Town to Race, with an additional Raucus setting that delivers full power, raises the spoiler and introduces a louder exhaust note.
The six-speed manual gearbox sends power to the rear wheels.
Engine response, suspension behaviour and steering feel are individually calibrated around the owner's preferences.
Limited Production and Theon Commission Pricing
Each Theon project involves approximately 6,000 hours of work at the company's Oxfordshire facility.
Only six clients worldwide are scheduled to receive completed commissions during 2026.
Prices start at £430,000, excluding the donor vehicle, shipping and local taxes.
The GBR008 reflects Theon's approach to building individually specified air-cooled 911s, with its mechanical calibration receiving as much attention as the exterior and interior finishes.
