Engine Stop-Start Systems Save Fuel at Low Cost

The rumble of idling cars and trucks is a familiar noise at America's intersections. But it's a sound that's likely to begin fading away in coming years: More and more automakers are using engine stop-start systems to boost fuel efficiency at relatively low cost.

    My experience with 5 year batteries in Texas is they always fail at 3 years. I don't think these systems will be very popular here.

    My 2013 Ram doesn't want to restart. I had guys behind me blasting their horn at me. Thought they were going to get out of their car and punch my lights out. DON'T LIKE IT!!!!!!!!!!

    Hi, i want to share with good idea.

    Scientists of ENU named by L. N. Gumilyov suggest the following steps to create a new type of diesel engine and bring it up to the consumer: the selection of promising species of aromatic plants, plant breeding and genetic engineering of selected species, the selection of essential oils, using laboratory methods, the study of the heats of combustion of essential oils, allocation essential oils, using semi-industrial methods, to bring biodiesel standards (EXPO-2017).

    This is dangerous. I have dangerous places to pull out with high speed cars coming at me. I don't trust it. Also it is VERY hot were I live so having the AC turn off at the temperatures that a manufacture would come up with is not acceptable.

    Maybe it's only at the initial cold start, but I had understood that most engine wear actually comes from starting the engine rather than driving. If there are any engine wear or battery replacement concerns, I'd think the gas savings is not worth it. Anyway, I have a Jaguar XJ loaner with this start/stop technology and it's awful - the (brand new) car shudders each time the engine shuts off and starts back up again. I would never buy a car with this technology unless there is an override switch (loaner is going back tomorrow so haven't bothered investigating this in the XJ).

    What happens after you jump start one of these cars with the stop / start systems? I would think you'd be at high risk of the engine automatically shutting off before the battery had time to recharge from the alternator.

    Very, very foolish idea. Just because it seems okay over in Europe, doesn't mean its a good idea in America. I can only imagine how many lawsuits will be filed after people start getting killed for this nonsense. The replacement cost of the starter and battery, not to mention all of the other bypass garbage needed to keep everything running while the engine is off, will negate any potential fuel savings. If you are spending $40,000 on a new car, the price of gas should be the least of your concerns. Buy a bicycle. The motor companies aren't installing this junk for your benefit, they're just trying to make it past their CAFE requirements.

    Bought a 2017 Ford F-150. HATE HATE HATE THIS STUPID FEATURE! Shutoff delay is way to short, we need a turn on option NOT TURN OFF, has to be hard on the engine, battery, starter. I've only had my truck for a month now and at least a dozen times it was restarting before completely shutting down.
