BEL001 is an exquisite, carbon fiber-bodied 911 that weighs just 2,788 pounds.
It may look like a classic Porsche, but this 964-based beauty boasts thoroughly modern mechanicals. The 3.6-liter flat-six engine produces 394 horsepower and 367 lb-ft of torque, ample outputs for a car weighing in at 2,788 pounds. Theon says the supercharger provides lag-free torque but still has the top-end surge associated with a naturally-aspirated flat-six, indicating a positive displacement supercharger.
A bespoke stainless-steel exhaust system with equal-length headers maintains the sonorous howl, with very little supercharger whine intruding on the sound. The motor features flowed and ported heads, Mahle barrels and pistons, and independent throttle bodies.
Instead of intercoolers, Theon Design has elected to fit twin charge coolers that work with an integrated water-methanol injection system. This not only provides cooling but improves performance by upping the fuel octane rating from 98 to 110+.
Company founder Adam Hawley explains why the company went for charge coolers over an intercooler: "This setup means we can avoid adding air intake apertures to the bodywork, [and] retain the super-clean, distinctly 'Theon' look that's so important to us, both in the engine bay and externally."
BEL001 sends power to the rear wheels via the original G50 five-speed manual gearbox. Theon Design has, of course, rebuilt the transmission for the perfect shift feel and has also fitted a new limited-slip differential. This particular model features semi-active suspension too.
Developed in partnership with TracTive, the system is said to deliver impeccable handling and composure. Five switchable modes - controlled by a retro-styled metal rotary switch - provide the driver with the ideal setup, no matter the terrain.
Of course, customers don't have to stick with a 3.6-liter. The firm also offers clients a choice between naturally aspirated or turbocharged 3.8-liter and 4.0-liter engines.
All of that is deeply impressive, but it pales in comparison to the aesthetics. In terms of style, BEL001 is simply breathtaking. Painted in Aquamarine - a shade that pays tribute to a '50s Porsche 356 color - the sophisticated hue has been paired with yellow Porsche decals on the lower parts of the doors and the engine lid.
The carbon fiber body is equal parts dainty and voluptuous. The simple shape of the early 911 works well with the wide rear arches and the tasteful tea tray spoiler. Four subtle exhaust tips sit flush with the rear bumper. Gold-painted Fuchs-style wheels round everything off nicely. It's just as gorgeous as CHI001, Theon's other recently unveiled commission.
"Our team goes to extreme lengths to ensure that each commission delivers an exceptional driving experience; every component is scrutinized and assessed with a laser-like focus, then tweaked to deliver optimal performance, quality, and refinement," explains Hawley.
Touring front seats, based on Porsche Recaro frames, have been fitted to the cabin and trimmed in gorgeous tan leather. This rich hide extends to the rest of the interior, such as the dashboard, where you'll find Aquamarine-colored inlays. Peek through the three-spoke steering wheel, and you'll spot the black Porsche gauges with green numerals.
Theon Design has gone the extra mile and finished the trunk in the same fine materials as the cabin - even the carbon fiber gas tank has been trimmed in black leather. BEL001 isn't without modern amenities, though. There's a magnetic wireless charger that allows a smartphone to be attached and serve as a navigation system.
Like rival company Singer, Theon Design's commissions don't come cheap. Prices start from around $456,000 - and that excludes the donor car. Each build takes 18 months to complete but clearly, they're worth the time and money.
