The McLaren Senna represents the pinnacle of McLaren engineering. It’s the result of the British automaker’s goal to build a more potent machine than the P1 hypercar without having to rely on the latter’s hybrid technology. McLaren achieved that goal when it turned it into a ground-breaking, lightweight supercar that defied even our highest of expectations. But as impressive as it was from a technical standpoint, the Senna still had to prove that its performance chops are as good as advertised. That opportunity finally came when the Senna did a top speed run at the Johnny Bohmer Proving Grounds in Merritt Island, Florida. The results, as you might expect, came with a few surprises.
