825ps 4.0-Liter V8 Twin-Turbo Engine

The Senna GTR's M840TR 4.0-liter V8 twin-turbo engine produces a maximum output of 825ps and 800Nm of torque. Engine control system modifications and the removal of secondary catalytic converters boost the maximum output by 25ps over the standard model.

With a dry weight of 1,188kg, the lightest of any McLaren production car, the power-to-weight ratio is an astonishing 694ps/ton. The transmission is the same 7-speed + reverse seamless-shift gearbox (SSG) with launch control as the standard model.

Aerodynamics have also seen significant advancements. Compared to the Senna GTR Concept unveiled in 2018, the front splitter has been reshaped, the rear diffuser is smaller, and the rear wing design has been altered and positioned further back. This results in over 1,000kg of downforce, significantly exceeding the 800kg recorded by the standard model at 250km/h. Furthermore, the downforce 'rise curve' is entirely different, achieving similar levels of downforce at speeds 15% lower.

This enhanced downforce not only benefits high-speed cornering but also low-speed cornering and braking, enabling balanced performance in all driving situations.

Production Limited to Just 75 Units

The body utilizes a carbon fiber monocoque chassis, with a ride height of 1,195mm, 34mm lower than the road-going Senna. The front track is 77mm wider at 1,731mm, and the rear track is 68mm wider at 1,686mm.

The windscreen and side windows, featuring a sliding ticket aperture, are made of polycarbonate. A race-style dump-and-charge fuel filler is employed. The 19-inch center-lock forged alloy wheels, 10J front and 13J rear, are fitted with Pirelli slick tires.

The suspension has been changed from the road car's variable ride control to a simpler, lighter GT3 racing setup. The brakes feature larger 390mm multi-layer carbon-ceramic discs, derived from the 720 GT3 race car, and combined with the rear wing's airbrake function, offer a 20% performance improvement over the road car.



The interior is exclusively left-hand drive, catering to the majority of buyers residing in left-hand drive markets. The seats are racing seats with a 6-point harness, with a passenger seat available as a no-cost option.

As a track-only vehicle, it omits airbags, infotainment, and other driver assistance features. Instead, it includes a race-derived quick-release steering wheel with one-button-one-function assignment, LED indicators on the pods that count down distance to vehicles behind via collision avoidance radar, and a central display showing the rear camera feed as standard equipment.

The Senna GTR will be produced in a limited run of just 75 units at McLaren's Production Centre in Woking, Surrey, UK, with deliveries scheduled to begin in September 2019. The price is £1.1 million (approximately ¥157 million) including tax. Orders opened after the concept model's debut at the 2018 Geneva Motor Show, and the entire production run sold out within weeks.
