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. The
prototype previews the limited edition production model which produces a
staggering 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 and 800 Nm of torque.
This is 25 hp more than the standard Senna which can accelerate
from 0-100 km/h in 2.8 seconds before topping out at 334
km/h.
Production will be limited to 75 units and pricing
starts at US$ 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.
