Thornley Kelham’s reimagined Porsche 911 has delivered a notable result during Monterey Car Week, with one of the first cars from the company’s European Collection selling above its high estimate at RM Sotheby’s Monterey auction.
Offered as part of The Driver’s Philosophy Collection, the 1972 Porsche 911 European RS by Thornley Kelham brought $802,500. Beyond the number itself, the sale provides an early indication of collector interest in Thornley Kelham’s European Collection, a series that also includes the Porsche 356 European SL and the Jaguar XK European GT Coupé and Roadster.
“The sale of our Porsche 911 European RS at the RM Sotheby’s Monterey Auction is real recognition of the dedication and craftsmanship that goes into all our European Collection models,” says Simon Thornley, director and founder of Thornley Kelham. “After nearly two decades of restoring iconic automobiles for concours events around the world, this shows what an incredible job our team have done to create our own reimagined and re-engineered cars that are appreciated by discerning international collectors.”
The European RS is Thornley Kelham’s take on the ultimate air-cooled 911, drawing its inspiration from the Carrera 2.7 RSR while applying contemporary engineering and obsessive craftsmanship to the familiar formula. The goal isn’t simply outright performance, but a car capable of delivering the involvement of a vintage 911 without demanding all the compromises that traditionally come with one.
Production is limited to just 15 examples, and Thornley Kelham says each requires more than 6,000 hours to complete. Carbon fiber is used extensively, while much of the engineering and fabrication is handled in-house at the company’s Cotswolds workshop. The result combines lightweight construction and bespoke components with an interior finished to a standard expected of a modern high-end coachbuilt car.
The centerpiece, however, sits behind the rear axle. The European RS uses a naturally aspirated, 24-valve 4.0-liter flat-six based on the 993-generation engine, comprehensively re-engineered for the application. Output is 425 horsepower, but the headline figure may be the 9,000-rpm redline. A close-ratio gearbox sends power to the rear wheels, keeping the experience deliberately mechanical and analog whether the car is being driven on the road or pushed on a circuit.
That combination of old-school character and modern execution has become increasingly important in the world of reimagined classics, where the best cars must do more than simply add horsepower and expensive materials. They have to retain the qualities that made the original compelling in the first place.
RM Sotheby’s described the European RS as being “among the rarest and most thoughtfully engineered interpretations yet created,” an assessment that speaks to Thornley Kelham’s background. The company has spent 18 years restoring significant automobiles to concours standards, experience that now informs the design, engineering, and construction of its own reimagined cars.
The $802,500 Monterey result suggests collectors are beginning to value that approach accordingly. Thornley Kelham’s European Collection occupies an increasingly competitive corner of the collector-car world, but the formula is a familiar and appealing one: preserve the character and proportions that made the originals special, then carefully improve the engineering, performance, and usability around them.
For Thornley Kelham, it all comes back to the philosophy behind the European Collection – The Design. The Details. The Drive.
