Ayrton Senna’s 1991 Brazilian Grand Prix-Winning McLaren Heads to Auction

The McLaren chassis that carried Ayrton Senna to his first Brazilian Grand Prix victory one of the most iconic moments of his Formula 1 career will go under the hammer this December.

The car, McLaren MP4/6-1, powered by a Honda V12 engine, delivered Senna’s emotional home triumph at Interlagos in 1991. It was a victory that came after 10 previous attempts to win in front of his home fans and remains one of the most celebrated drives in Formula 1 history.

A Legendary Drive Under Extreme Duress

By 1991, Senna was already a two-time world champion and one of the biggest names in global sport. But his win at Interlagos was as much about grit as it was about talent.

In the closing laps of the race, Senna’s six-speed manual gearbox began to fail, leaving him with only sixth gear. With rain falling and Riccardo Patrese’s Williams FW14-Renault closing in, Senna was forced to adapt slipping the clutch through slower corners and relying solely on the brakes to slow the car, as engine braking was no longer possible.

The physical toll was immense. Senna battled severe muscle cramps and exhaustion, yet managed to hold off Patrese to take the chequered flag just 2.9 seconds ahead, securing a victory that became a defining moment in his career.

From McLaren Heritage to the Auction Block

Following the 1991 season during which Senna went on to win his third and final world championship chassis No. 1 was retired to what is now the McLaren Heritage Collection. It remained there until 2020, when it was sold privately.

According to RM Sotheby’s, which will handle the upcoming sale, the car was “returned to running and driving order as a condition of the current owner’s purchase.” It has not been shown or driven since, but was recently serviced and started by McLaren specialist Paul Lanzante Ltd in the UK ahead of the auction.

Expected to Fetch Up to $15 Million

The car will be offered during RM Sotheby’s three-day auction from December 8–11, with an estimated sale price between $12 million and $15 million.

For collectors and motorsport enthusiasts, the MP4/6-1 represents not just a piece of Formula 1 engineering excellence, but a symbol of Senna’s indomitable spirit a moment when sheer determination turned mechanical failure into one of the sport’s greatest victories.
