When McLaren announced the Senna GTR, the automotive world knew something extraordinary was on the way. The road-going Senna was already one of the most extreme cars ever built, but the track-only GTR took everything — power, aerodynamics, weight savings — and cranked it to 11.
Now, chassis #73 of just 75 units ever built is up for grabs on Bring a Trailer, offering one lucky buyer the chance to own one of the rarest and most uncompromising McLarens in existence.
A Machine Built for One Purpose: Speed
The Senna GTR is a racing machine that shares DNA with the street-legal Senna. Built around McLaren’s MonoCage III carbon-fiber monocoque, the GTR is lighter, stiffer, and even more purpose-driven than its sibling.
Engineers widened the track by over three inches at the front and nearly three inches at the rear to give it more stability through high-speed corners, and the aerodynamics package is a work of art: a massive front splitter, deep side skirts, a functional rear diffuser, and an enormous rear wing that integrates active aero and DRS technology. The result? Just 2,205 pounds of downforce at 155 mph, pinning the car to the pavement like a Le Mans prototype.
Power to Match the Aero
At the heart of this monster is McLaren’s twin-turbocharged 4.0-liter V8, tuned for track duty to deliver a staggering 814 horsepower and 590 lb-ft of torque. Coupled with the car’s featherweight 2,619-pound dry weight, the power-to-weight ratio puts it in a league shared by only the most exotic machines on the planet.
The seven-speed dual-clutch transmission delivers lightning-fast shifts, and the rear-wheel-drive layout keeps the car engaging while still allowing for precision on the edge of adhesion.
Race-Ready Hardware
Every inch of the Senna GTR is engineered for serious track performance. It features four-way adjustable Öhlins dampers, adjustable anti-roll bars, and a full telemetry suite for post-session data analysis. Built-in air jacks make wheel swaps and maintenance effortless, while the integrated roll cage and fire suppression system keep safety at a professional level.
Even the cabin is a study in focused minimalism: carbon-fiber racing seats with six-point harnesses, polycarbonate windows, a digital display for live data, and just enough creature comforts, including air conditioning to keep you cool while pushing the limits.
Chassis #73: A Special Example
This particular car, chassis #73 of 75, is finished in a jaw-dropping MSO Solar Yellow with livery inspired by Ayrton Senna’s iconic racing helmet. Inside, black Alcantara with yellow contrast stitching maintains the consistent theme. It’s a tribute to the man whose name the car bears, a reminder that this machine is built for drivers with the courage to explore the limits of physics.
Adding to its desirability, this Senna GTR has covered just 540 miles or o since new, making it one of the lowest-mileage examples available. It includes its factory build documentation, original delivery materials, and a clean ownership history, cementing its status as a collector-grade hypercar.
The Ultimate Track-Day Weapon
Owning a Senna GTR isn’t just about exclusivity; it’s about experiencing a car that operates at the razor’s edge of performance engineering. With its balance of power, aerodynamics, and downforce, it can lap circuits with times that rival those of GT3 and GTE race cars.
And because McLaren delivers these cars through its customer racing program, owners enjoy a direct line to factory support and expertise, making it as practical as a hypercar can be for regular track use.
A Collector’s Dream
With only 75 units built, the Senna GTR is already a modern hypercar icon. Its combination of extreme rarity, cutting-edge engineering, and motorsport pedigree ensures it will remain highly sought after for decades to come. This particular example, with its low mileage and stunning MSO specification, stands out even in that rarefied crowd.
For collectors, investors, or drivers with access to a private track, chassis #73 represents an opportunity to own not just a car, but a piece of automotive history, one that distills McLaren’s racing spirit into a track machine that defies belief.
