Nick Mason's McLaren F1 GTR prototype set for Monterey sale

The automotive world is abuzz with anticipation as the McLaren F1 GTR chassis 10R a true icon of 1990s motorsport, prepares to take center stage at RM Sotheby’s 2026 Monterey Car Week auction on August 15. This extraordinary vehicle, with its distinctive pop art livery and rich racing pedigree, is poised to become the most expensive McLaren F1 ever sold, with an estimated value in excess of $35 million.

Designed by the legendary Gordon Murray the McLaren F1 was an engineering marvel that combined cutting-edge technology with breathtaking aesthetics. The GTR variant, developed for competition, took this innovation to the racetrack, securing a historic victory at the 1995 24 Hours of Le Mans. Chassis 10R, the first of its kind, played a pivotal role in this success story, serving as the bridge between the initial 1995 model and the more advanced 1996 specification.

The evolution of a racing legend

The McLaren F1 GTR underwent significant enhancements for the 1996 season, including extended bodywork, a more aggressive front splitter, and a lightweight magnesium gearbox casing. These modifications not only improved performance but also reduced the car’s weight by a substantial 84 pounds. Chassis 10R, completed in December 1995, was the first to embody these upgrades, making it a crucial piece of McLaren’s racing history.

Initially retained by McLaren for testing and promotional duties, chassis 10R participated in winter testing at Magny-Cours and was driven by works drivers, including 1995 Le Mans winner JJ Lehto. Its brief but meaningful competition record includes a notable performance at the 1996 Le Mans Pre-Qualifying session, where it placed eighth in class and 20th

A celebrity-owned masterpiece

In 1999, chassis 10R found its way into the hands of Nick Mason the renowned drummer of Pink Floyd. Mason, a passionate car collector, ensured that the vehicle received the utmost care and attention. The car was converted for road use and registered in the United Kingdom as “K40 MCL”. Under Mason’s ownership, chassis 10R has been meticulously maintained by Lanzante Limited a specialist firm with deep ties to McLaren’s racing heritage.

The distinctive scarlet-and-yellow “96 GTR” graphics, applied during Mason’s ownership, set this chassis apart as the only F1 GTR to wear a factory livery of this kind. This unique combination of celebrity ownership, rare specification, and striking aesthetics makes chassis 10R a standout piece in the world of collectible automobiles.

The journey of restoration and preservation

Chassis 10R has undergone two significant restorations, each overseen by the expert team at Lanzante Limited. The first restoration followed an off-road incident during a 2009 road test, while the second was necessitated by an accident during a 2017 Goodwood Members’ Meeting demonstration. These restorations, along with regular maintenance, have ensured that the car remains in pristine condition, mechanically and cosmetically.

Mason’s commitment to preserving the car’s excellence is evident in his “open checkbook” policy, which has allowed Lanzante Limited to perform extensive work on the vehicle. A recent inspection by Lanzante Limited is on file, providing potential buyers with assurance of the car’s exceptional condition. Chassis 10R has also made appearances at prestigious events such as Rétromobile, the Goodwood Members’ Meeting, and the 106 Drivers Club’s road rallies, further cementing its status as a racing icon.

The upcoming auction at RM Sotheby’s Monterey Car Week presents a rare opportunity to acquire one of the most significant and unique McLaren F1 GTRs ever created. With its rich history, celebrity provenance, and unparalleled condition, chassis 10R is poised to set a new benchmark for the most expensive McLaren F1 ever sold. As the automotive world watches with bated breath, this legendary vehicle is ready to take its place in the annals of motorsport history.
