McLaren used Formula 1 World Champion Ayrton Senna's name on a new supercar shown to the world in 2018 as the most track-focused model in the British company's growing lineup. With all the aero possible and a screaming 789 horsepower routing power to the rear wheels only, the Senna looks and sounds like a full-blown racecar. But for those buyers who needed even more hardcore performance, McLaren then built a limited run of 75 examples of the Senna in track-only GTR spec with 814 horses on tap. Now, chassis number 28 has popped up on the auction website Bring a Trailer where it's sure to climb well into the seven-figure range.

A Senna For The Track Only

All the performance enhancements to a "regular" Senna that make a GTR the ultimate billionaire's track toy are simply too long to list here. Those wings manage to create 2,205 pounds of downforce at speed, while the track has been stretched by three inches at the front wheels and 2.7 inches at the rear. Overall, the GTR comes in at 2,619 pounds—which helps McLaren justify the claim that the Senna GTR remains the best performing vehicle the company has ever built outside of legit Formula 1 racecars.

The interior features plenty of GTR badging on the multiple carbon-fiber and Alcantara surfaces. A yoke-style steering wheel with F1-style buttons greats the driver, though surprisingly, a passenger seat with harnesses allows for anyone bold enough to take a spin around the track. An integrated roll cage, fire suppression system, and air jacks fit into the mix, while certain sacrifices are made to comfort including an air conditioning system.

Minimal Photos, Lots Of Track Time

For a car that will undoubtedly fetch above $1 million, the BaT listing features an almost hilarious dearth of photographs, including zero shots of the mid-mounted engine or underbelly. Perhaps the selling dealer believes anyone willing to drop the kind of money to buy a Senna GTR will come visit in person—or simply doesn't mind any potential damage that might have been incurred during the roughly 400 miles of track driving this GTR performed since new.

​​​​​​​Multiple photos in the gallery do include shots that look like Sonoma Raceway and Laguna Seca, while the original invoice scan reveals almost $70,000 of McLaren Special Operations bespoke options like the Gulf-inspired livery and painted wheels. Bidding alread sits at $250,000 with eleven days remaining until the final gavel.
