Is McLaren Being Smart or Cheap by Skipping a Limited-Slip Differential?
Some say an open differential offers a raw and unadulterated driving experience, but others say it’s unsafe, even dumb.
The average driver probably doesn’t understand how a differential works, what it does, or what a big impact it has on driving dynamics. If you don’t agree, try to explain to someone how the inside wheel spins at a different rate of speed than the outside wheel during a basic turn. Now watch that person get completely confused.
But once you grasp the role a differential plays, it’s hard to comprehend why an exotic ride like the McLaren 570S, or even the multi-million-dollar P1, doesn’t have one. After all, these track-slaying machines are at the pinnacle of handling. So in theory, they should have a limited-slip differential.
This video by Jason Fenske of Engineering Explained shows us how the open differential in the McLaren 570S works. He says it does the job “just fine.” But does it? Can a lightweight car with 572 horsepower going to its rear wheels really do “just fine” with an old-school diff?
