McLaren Senna GTR Snapped On The Track Putting Its 2,205 Lbs Of Downforce To Work

McLaren used the 2018 Geneva Motor Show to introduce the Senna GTR concept and now spy photographers have caught the model undergoing testing for the first time.

Dressed in heavy camouflage, the prototype previews the limited edition production model which produces a staggering 2,205 lbs (1,000 kg) of downforce. In order to achieve this massive number, the GTR has been equipped with wider fenders and a larger front splitter. The GTR’s rear diffuser and active rear wing also work together by “coupling” the airflow to produce greater, and more accessible, downforce at lower speeds.

The changes don’t stop there, as the GTR has a wider front and rear track as well as center-locking wheels. The cabin has also been stripped of all non-essential equipment to reduce weight. As a result, the airbags and infotainment system have been removed. Interestingly, the air conditioning system will remain and this decision has been billed as “an exception to the rule of absolute minimalism.”

The track-focused upgrades continue elsewhere as the suspension geometry, springs, dampers and anti-roll bars have been “developed from the system engineered for McLaren’s GT3 customer racing program.”

Power comes from an upgraded twin-turbo 4.0-liter V8 engine that produces 814 hp (607 kW / 825 PS) and 590 lb-ft (800 Nm) of torque. This is 25 hp (18 kW / 25 PS) more than the standard Senna which can accelerate from 0-62 mph (0-100 km/h) in 2.8 seconds before topping out at 208 mph (334 km/h).

Production will be limited to 75 units and pricing starts at $1.4 million. All of the cars have already been spoken for and deliveries are slated to begin in September when production of the street-legal Senna is complete.
