With its 789 horsepower and weight of just over 2,640 pounds, the McLaren Senna was a revelation in the automotive industry. But, for the British automaker, it wasn’t quite good enough. So they tweaked and toyed with it to create an even more insane version: the McLaren Senna GTR.
Lighter, faster, and more powerful than the street-ready version, this edition of the hypercar is a track-only rocket that’s good for a blistering 813 horsepower from its 4.0-liter, twin-turbocharged V8 engine. To match that increase in power, they also dropped the weight down to just 2,619 lbs, giving the GTR a power-to-weight ratio of 694 bhp-per ton — an insane figure by any measure. That also means that, outside of their F1 car, this is the quickest McLaren ever built. It also boasts a Monocage III-R central structure, a carbon fiber safety cell, an aluminum front subframe and engine frame, and composite crash beams at the nose and tail. The craziest part, however, is that only 75 examples of this $1.4M hypercar will ever be built and they’ve all already been purchased.
