Progress never stops when it comes to automobiles. McLaren is very serious about the earlier statement, making sure that it always improves upon its existing models. The company recently took a critical look at the hardcore Senna and thought it could go faster. Hence came the McLaren Senna GTR.
The stock McLaren Senna is no slouch. Extracting 789hp from a twin-turbocharged 4.0-litre V8 packaged in a lightweight chassis and bodywork, the road-legal race car . It was made for tearing up racetracks around the world with absolute authority. McLaren just took the Senna back home, further reducing its mass, sharpening aerodynamics, and increasing output in search of more performance. The end result? 2020 McLaren Senna GTR.
814 horses rearing to go, packed in a lithe 1,188-kg body means that McLaren Senna GTR can lap racetracks at breakneck speeds without losing its cool.
The Senna GTR’s racier M840TR engine generates 814hp and a monumental 800Nm of torque. Some of the extra power and torque comes from removing the secondary catalytic converter. Removal of said component has resulted in the Senna GTR making a throatier, louder rasp through its unique exhaust ports.
It’s worth noting that McLaren built this car specifically to drive around racetracks. Everything necessary for a track car can be found in the Senna GTR. Onboard pneumatic jacks, fire suppression system, pit radio, front- and rear-facing cameras, data logger, and air-conditioning. Despite the extra additions, weight is down by 10kg, with the Senna GTR weighing just 1,188kg dry. This gives it a power-to-weight ration of 694 horses per tonne. That is more than a Bugatti Veyron Supersport, which is no mean feat.
Since it is a track car, McLaren made sure that Senna GTR carries even more speed at every point on any racetrack. Downforce at 250kph totals 1000kg versus the roadgoing Senna’s 800kg. Despite increased downforce, the track-focussed Senna slips through the air more efficiently than its milder iteration. It is also lower, wider, and wears fatter rubber. McLaren claims due to the presence of full traction control, ABS, and collision radar, Senna GTR’s performance is accessible to 95 percent of drivers.
That humongous wing is part of an active aerodynamics package that exerts a tonne of downforce on the GTR.
McLaren has only announced 75 units of the Senna GTR against the road-going Senna’s 500. And yes, this $1.4-million hypercar is already sold out. “The McLaren Senna was designed from the outset to be an extreme track car, but the 2018 McLaren Senna GTR Concept suggested how much more further we could go and now, free from the constraints of road car legislation and motorsport competition rules, we have pushed the limits of what is technically possible to advance circuit driving capability to another level entirely,” said McLaren Automotive CEO Mike Flewitt.
