The Internet of Noisy Things. That car, truck, or bike might not sound as hot as you think it does.

Stomp on the gas in a new Ford Mustang or F-150 and you’ll hear a meaty, throaty rumble — the same style of roar that Americans have associated with auto power and performance for decades.
It’s a sham. The engine growl in some of America’s best-selling cars and trucks is actually a finely tuned bit of lip-syncing, boosted through special pipes or digitally faked altogether. And it’s driving car enthusiasts insane.
Fake engine noise has become one of the auto industry’s dirty little secrets, with automakers from BMW to Volkswagen turning to a sound-boosting bag of tricks. Without them, today’s more fuel-efficient engines would sound far quieter and, automakers worry, seemingly less powerful, potentially pushing buyers away.
