The annoying whirr of windscreen wipers may soon be a thing of the past.
McLaren is designing a sports car that uses a system adapted from fighter jets to keep a driver’s vision clear in bad weather without the need for blades.
It is believed to involve high-frequency sound waves similar to those used by dentists for removing plaque from patients’ teeth.
The Formula One firm, based in Surrey, is developing the method for its new supercar, expected to roll off the production line in 2015.
If successful, it could be used in family cars. McLaren is reluctant to release details about the wiper-free windscreen, which could cost only £10 (R168) per vehicle to mass-produce.
Chief designer Frank Stephenson said the system had already been proven by the military.
Experts believe it makes use of ultrasound to create tiny vibrations that shake off rain, insects, mud and other objects landing on the screen. McLaren said the new system could improve cars’ fuel economy – and prevent the problem of wiper blades freezing to the glass in winter. -Daily Mail
