McLaren dropped this earlier on their social media pages, with the caption:

"Your first look at something new, more on this coming soon."



Followed by a comment shortly afterwards:

"We don't like to keep you guessing for too long. It's a track-focused development of the 650S and it will be at the Geneva Motor Show alongside the McLaren P1™ GTR."
