For those who found the track-focused Senna still a bit too soft, McLaren has now announced a track-only GTR version, which gets more power, more downforce and bespoke bodywork. At US$1.4m each, all 75 examples have already been sold.
The headline figure is the 1,000kg of downforce that’s produced thanks to the unique bodywork, which has been previewed in a sketch. The larger rear wing and diffuser work together to achieve even higher aerodynamic efficiency, even at lower speeds.
The Senna GTR also gets a bigger front splitter, as well as a wider track, front and rear, and wider fenders to hide the Pirelli racing slicks. The suspension and brakes are developed from the road car, using technology from the GT3 customer racing program. McLaren expects 20% greater maximum deceleration, with resulting forces in excess of 3g.
Power comes from McLaren’s now familiar 4.0-liter twin-turbo V8, now putting out 814bhp (25bhp more than the road car) and 800Nm.
The latest track-only toy is built around McLaren’s carbon-fiber Monocage and will be left-hand drive only. Compared with the road car, unnecessary weight is stripped out, eschewing airbags and the folding instrument screen. Air-conditioning remains standard-fit, as well as a rear collision avoidance system.
Dynamic testing begins this month and deliveries are expected to begin in September 2019 when production of the road-legal McLaren Senna ends.
