This New Porsche One-Off Is an Ode to a 911 Turbo Prototype and Is Now up for Grabs

A unique Porsche built for one of its founder’s family members will hit the auction block later this month.

RM Sotheby’s will take bids for the 2024 911 “Turbo Remastered” that was gifted to Louise Piëch, the daughter of Ferdinand Porsche. The stunning speed machine was built by the automaker’s Sonderwunsch program to celebrate a half-century of the performance model.

Introduced in 1975, the legendary 911 Turbo, or 930 as it is also known as, was the first version of Porsche’s iconic model to come equipped with a turbocharger. Force induction may be commonplace today but back then adding the feature to the 911 was considered a bold move. Mating the car’s 3.0-liter flat-six with a KK&K turbocharger—and boosting output to 296 horses and 304 ft lbs of torque—turned out to be a winning move and the variant would serve as the 911’s top-of-the-line variant for the 24 years it was in production.

Thanks to Piëch’s family connections she was able to snag one of the first road-going examples of the 911 Turbo, a prototype she received in 1974. Unsurprisingly, there were some major differences between it and the finished vehicle, including a narrower track and a smaller 2.7-liter flat-six. It is this car that served as an inspiration for Piëch’s 911 “Turbo Remastered.”

The one-off coupé, which was given to Piëch for her 70^th birthday, is a result of a collaboration between Style Porsche, Porsche Exclusive Manufaktur, and Porsche Middle East and Africa FZE. The car is finished in GT Silver, covered in tartan-patterned decals, and rides on a set of black five-spoke wheels. The cabin is done up in Lipstick Red and features red-blue tartan trim inserts in reference to her prototype. Inside and outside, you’ll find branding identical to that found on the original 911 Turbo.

The car’s powertrain is all-new, though. The 911 “Turbo Remastered” is powered by the turbocharged 3.75-liter flat-six in the 992-generation version of the model. That mill is an eight-speed PDK gearbox and makes 572 hp and 553 ft lbs of torque. It can sprint from zero to 62 mph in 2.8 seconds and reach a top speed of 199 mph.

Piëch’s one-off 911 “Turbo Remastered” will be sold through an online auction that runs from Wednesday, November 20, to Sunday, November 24. The car is expected to sell for between $330,000 to $430,000. The high end of the estimate is about double what a brand-new 911 Turbo costs.
