You can probably count the real-world spottings of the Senna using no more than the fingers on one hand and we're here to deliver the freshest stunt of the kind.
To be more precise, the 722-P15, which is the development car for the 800 hp beast, has recently been spotted performing testing in South Africa.
It's not uncommon for carmakers to continue testing even after a machine has been officially introduced (keep in mind that customers deliveries have yet to kick off), so this spotting shouldn't come as a surprise.
The velocity monster was spotted doing its thing on the Kyalami Circuit, which used to host the South African Grand Prix back in the day, so the environment for the speedy play was perfect. And while McLaren wasn't particularly successful on the said track, it did enjoy a few wins over the years - pixel tip to Zero2Turbo for the piece of footage showcasing the Macca's adventure
