Track-only McLaren Senna GTR confirmed, 1,000 kg downforce monster

Just when we thought things couldn’t get more extreme with the McLaren Senna, the Woking-based carmaker has just released initial details of a track-only McLaren Senna GTR variant that is currently in its prototype testing stage.

Like the sold-out Senna, production numbers of the GTR variant of McLaren Ultimate Series is capped at 75 units worldwide and all of them are already snapped up. The track-only machine will be available in left-hand-drive configuration only. Deliveries are expected to begin from September 2019 once production of the road-going Senna is complete.

While the car is in its development phase, based on the official design sketch from McLaren, we can tell that radical does not even begin to describe its track-carving intent. The chassis of the Senna GTR will feature a wider front and rear track, wider fenders and ridiculously wide front splitters and diffusers. The end plates of the active rear wing appear to extend downwards towards the diffuser presumably to promote cleaner airflow and downforce.

McLaren claims that the revisions on the bodywork allow the Senna GTR to generate 1,000 kg of downforce – 200 kg more than its road-legal brethren. To complement the 1-tonne downforce, engineers have fitted the car with a suspension system derived from the brand’s GT3 customer racing programme as well as Pirelli slick race tyres. Together, the Senna GTR is projected to deliver 20 per cent greater maximum deceleration with forces exceeding 3g.

The M840T 4.0-litre twin-turbocharged V8 in the Senna GTR application makes 825 hp and 800 Nm of torque to drive the rear wheels. Although the final vehicle weight is yet to be confirmed, the GTR will weigh lesser than the regular Senna’s 1,198 kg dry weight.
