It's not a looker, but that wasn't the point
The odd-looking Senna is the ultimate track McLaren at the moment, a form-over-function dedication to one of the greatest race drivers of all time.
"McLaren Senna to me as an engineer is about taking the levels of engagement as a driver to the next levels possible," said Richard Farquhar, powertrain and vehicle engineering director.
"He [Ayrton Senna] was utterly focused to be the best that he could be, to achieve the highest levels in his sport. In McLaren Senna bearing his name really resonates to be utterly focused, to be the best it can be."
Check out the video for the full breakdown, filmed during hot weather testing in Spain. The theme is clear: the drive to be better was a clear focus for the engineering team.
