The New Technology That Can Save You Hundreds On Gas
Over the years, one urban fuel-efficiency myth has been pervasive—that you’ll save gas by letting your car idle rather than shutting the engine off when, say, waiting at the curb for someone running into a store. Popular Mechanics, AAA, and others have busted this myth, pointing out that a vehicle gets negative miles per gallon while idle. The consensus advice now is that if you car is stopped for more than a minute, the smart move is to turn the engine off.
The arrival of auto stop-start, a technology most often seen in hybrids, does this work for you, and not only if you’re idle for minute or more. The technology has slowly been spreading beyond hybrids to a few vehicles powered by traditional internal combustion engines, and new research from AAA indicates that this is a good thing.
