Read the original press release for the road car here.

An excerpt:

A complex three-part rear diffuser beneath the F1’s tail incorporates a central single surface and two reflex shapes each side generate sufficient downforce to overcome the car’s natural aerodynamic lift.

But hell, what would McLaren know? After all, they also say:

While most existing production cars are tested in fixed-floor tunnels in which the test-car’s wheels are stationary, every Formula 1 racing car designer knows that modern moving-ground wind tunnels provide the only accurate representation of actual-car aerodynamic behaviour.

...and everyone knows from what 'Aerohead' writes here that there's no need for moving ground wind tunnels!

Again, what would McLaren know?

My references say 136kg downforce at 240 km/h.

(But for people who actually want to learn something, the most interesting thing I found when revisiting the car's aero details is the active control of the location of the centre of pressure.)
