McLaren Could Replace Windshield Wipers With A Sound-Based Force Field

In the past year and a half, McLaren has brought us a wonderful supercar, the MP4 12C, and an even more wonderful hypercar, the nearly perfect P1.

For its next trick, it may get rid of the windshield wiper.

That's according to an interview a designer gave to the UK's Sunday Times.

It seems McLaren is working on a system, adapted from fighter jets, that will use high-frequency sound waves to create a kind of force field that will keep water, as well as insects and other debris, off the windshield.

Getting rid of that chunk of plastic would improve the car's aerodynamics — lowering drag and making it more fuel efficient.
