McLaren has revealed the new track-only Senna GTR with incredible downforce and even more power.
When McLaren unveiled the Senna at the 2018 Geneva Auto Show, it was to the excited gasps of the assembled automotive world. With unbelievable power and performance, The Senna was praised as one of the best performance vehicles ever made.
As with most McLarens, the Senna was advertised as being a track-focused but road-legal car that millionaires could drive to and from the race track. Well, now McLaren has ditched road-legality in favor of even more track performance with the Senna GTR.
The British carmaker didn’t release specific performance figures for the Senna GTR, but they did say that it is the “quickest track McLaren outside of Formula 1.” They also mentioned that the Senna’s 4.0-L twin-turbo V8 engine has been tuned to produce 35 more horsepower, up to 814 hp and 590 lb-ft of torque.
On a car that only weighs 2619.1 lbs dry, that’s a pretty incredible power-to-weight ratio.
The Senna GTR also massively improves the Senna’s downforce, increasing it to 2,204 lbs compared to the original’s 1,763 lbs at 155 mph. The GTR can also achieve that downforce at 15% slower speeds than the original Senna thanks to enhancement to the car’s aerodynamics, including the new front splitter, larger rear diffuser, and active front aero blades.
Despite the added downforce, McLaren also says the GTR has less drag than the original Senna thanks to a redesigned LMP1-style rear wing that improves air flow.
The old active suspension on the original Senna has been tossed in favor of a more traditional setup of aluminum double wishbones, springs, uprights, anti-roll bars, and 4-way adjustable dampers derived from McLaren’s GT3 program. There’s no need for a suspension that can deal with the occasional pothole if the GTR is only going to be driven on a track, and the GT3 suspension is much lighter without all the active sensors and whatnot.
Another sacrifice for the track-only car is that it will only come in left-hand drive. McLaren notes that most of their customers are in left-hand markets, and being a track-only car makes driving on the right an unnecessary extra.
Advanced traction and stability control follow McLaren’s goal of allowing 95% of drivers to access 95% of the GTR’s overall performance. It sounds like a lofty goal of turning any driver into a racer, but if anyone can do it, it’s McLaren.
Getting behind the wheel of the Senna GTR will set you back $1.43 million. If you could still buy one--all 75 have already been sold.
