As explained in detail yesterday, the McLaren Senna is no joke. Never before has a road-legal car combine this much power with such a complex active aerodynamic package in a chassis as light as McLaren's most carbon-intensive yet. Forget the level of P1 GTRs. This is like a 720S' platform not dialed up to, but multiplied by eleven.
The numbers include a dry weight of 2641 pounds propelled by 789 horsepower, a stopping distance of 705.4 feet from 186 mph, and brake temperatures that are 302° F lower in average that where carbon ceramic systems usually operate.
Thanks to being like cybernetic Swiss cheese, at 155 mph, the Senna also pushes itself to the road with an additional 1763 pounds, balanced in the corners by the active rear wing and some equally busy flaps at the front. The Senna is so focused on its lap times that even its plate holders are bolt-on extras that pop off once you enter the pits, so they don't compromise the airflow.
It's no secret that once it has built the 500 "regular" Sennas, McLaren is going to build somewhere between 60-100 Senna GTRs. Even more exciting is what could follow that. McLaren CEO Mike Flewitt has that they are looking at racing the Senna, may the rule changes open the gates for them in 2020:
We are working on a plan. The way it is designed from an aerodynamic perspective, and the sheer balance of our cars, would be very, very competitive. You could never say outright that you’d go and win, but we wouldn’t go in with any other intention.
Back at Woking, parked on the MTC's Boulevard, a 1995 McLaren F1 GTR known as chassis #01R just started smiling.
In the meantime, Senna drivers can experiment with what's more enjoyable: shifting in Sport mode, in which the car will cut spark while continuing to fuel before re-igniting the mix for the next gear, or in Track/Race, when the Senna goes for the "inertia push," using residual torque from the driveline to pull through the gear change.
Now, here's Mark Gayton, Mclaren's Project Manager to tell us more on how this machine all came together:
