Only 765 examples of the latest Long Tail are being offered, and this one is not like the others. To see what the car is capable of before digging in, let’s watch the McLaren 765LT dyno testing by Hennessey Performance. To keep the beast on the rollers required every strap in the shop, and McLarens demand a unique procedure. The car is constantly thinking of your safety, so if the front tires are not at the same speed as the rear, the stability system locks the brakes. So the latest AWD model from Dynojet turns the front wheels while also placing a load on the powertrain. Locked in 5th gear and running VP Racing Fuel it made over 747 horsepower at the wheels. Once again, McLaren has sandbagged the world by making much more power than they advertise, and we’ve seen it across their lineup. What will it make once John and his team are done? You will see it here first!
