KRMG's Clark Howard says 'stop-start' tech is great gas saver

Most of us spend a lot of time in TRAFFIC.

And that's why KRMG's Clark Howard says you need stop-start technology.

Clark says stop-start tech started out mostly on hybrid cars about 15 years ago.

But now he says it's on more and more mainstream cars too.

It shuts off your car's engine when you're stopped, like at a long red light for example, and then quickly starts it back up when you hit the gas.

"It's a fantastic fuel-saving feature because it eliminates, in stop-and-go driving, all that waste of gas that happens, when you're stopping not going," Clark says.
