Theon Design has introduced its most extreme creation yet: the Theon R, a restomod based on the classic 911 from the 964 generation. This remarkable coupe features body panels crafted from F1-grade carbon fiber, resulting in an impressive curb weight of under 1,000 kg (approximately 2,200 lbs).
Lightweight Performance with a Powerful Engine
While the 2025 GT3 RS currently holds the title for the lightest Porsche 911 available, Theon R takes lightweight engineering to a new level, making the GT3 RS look heavier in comparison. Classic cars tend to weigh less than their modern counterparts due to their simpler designs, and Theon has taken this concept to the extreme. The 964 chassis, used as the foundation for the Theon R, is lighter than contemporary models, thanks in part to a rigorous diet of high-performance materials.
Weighing in at “less than” 1,000 kg (2,205 lbs), the Theon R surpasses even the original 1989 Mazda Miata, which weighed 2,210 lbs (1,002 kg). Theon achieved this remarkable weight by utilizing carbon fiber extensively throughout both the exterior and interior of the vehicle, making it significantly lighter than the modern GT3 RS, which weighs 3,268 lbs (1,482 kg).
Engine Specifications and Performance Metrics
Although modern engines generally produce more power, the difference isn’t as significant as one might expect. The Theon R is powered by a 4.0-liter air-cooled flat-six engine that delivers 500 hp (507 PS), while the water-cooled flat-six of the GT3 RS produces 518 hp (525 PS). This gives the Theon R an impressive power-to-weight ratio that enhances its performance capabilities.
While it may not outpace the GT3 RS on a racetrack, the Theon R boasts a seam-welded chassis and a carbon tub bonded to the structure, providing torsional rigidity comparable to modern Porsche models.
Classic Design Elements and Modern Features
The design of the Theon R draws inspiration from Porsche’s rich motorsport heritage. Its magnesium wheels, reminiscent of the original 1972 911 ST, now feature carbon elements, while the iconic whaletail rear wing pays homage to the 1974 Carrera RSR. Standard equipment includes carbon-ceramic brakes, a Wavetrac limited-slip differential, and bespoke MCS dampers.
Theon claims the R can accelerate from 0 to 60 mph (96 km/h) in just 3 seconds, reaching 100 mph (160 km/h) in 6.5 seconds—figures that closely match those of the 2025 GT3 RS. However, potential buyers of the GT3 RS can expect to pay around $241,300 (£192,600) and take delivery in a few months. In contrast, commissioning a Theon R requires an 18-month wait and an investment of $1 million (£790,000). The choice is clear for those seeking the ultimate in bespoke performance.
