McLaren confirmed that the track-only Senna GTR will make its first appearance at the 77th Goodwood Members’ Meeting on April 6 – that is, next Saturday.

The automaker’s “most extreme track car yet” will lead a track parade on the historic Goodwood Motor Circuit ahead of a very special selection of McLaren cars.

These will include a P1 GTR, a P1 and the road-legal Senna, as well as the famous McLaren F1 XP5 prototype, the very same car that held the record of the world’s fastest production car before Bugatti dethroned it many years later.

The Senna GTR is McLaren’s track version of an already stunningly capable hypercar, with the British company calling it their quickest track model outside of Formula 1. The twin-turbo 4.0-liter V8 produces 814hp (825PS) and 590lb-ft (800Nm) of torque, 25hp more than the road-legal Senna.

The power increase is combined with a very strict diet that makes the Senna GTR tip the scales at 1,188kg (2,619lbs) dry. Power to weight ratio is now set at 684hp/tonne. As you would expect from a McLaren with the GTR designation, the sharp bodywork has gained a wild aero agenda. The downforce levels are the same with the regular Senna at an eye-popping 1,000kg (2,205lbs), but these are produced at a 15 percent lower speed.

The suspension uses components straight from McLaren’s GT3 racing program and there are three driving modes: Wet, Track and Race – no need for Normal here. All 75 examples planned for production are already sold out, despite the $1.65 million (plus taxes) price tag, with deliveries set to commence in September.
