Toyota’s Prius hybrid is becoming a little less quiet with a new electronic humming device that is the automaker’s answer to complaints that pedestrians can’t hear the top-selling car approaching.
The 12,600 yen ($148) speaker system that goes under the hood of the third-generation Prius sets off a whirring sound designed to be about the same noise level as a regular car engine so that it isn’t annoying, Toyota Motor Corp. said Tuesday.
It goes on sale Aug. 30 in Japan, and owners pay extra for installation charges. Its use is voluntary.
