Would you be willing to slow down your highway driving if it meant saving money on fuel spending and reducing your emissions? I don't.

Ford commissioned a survey through Penn Schoen Berlandalso and found that 64 percent of American drivers are driving less frequently to save on gasoline. As for those willing to lighten up on the gas pedal, 41 percent are slowing down to reduce fuel consumption and 10 percent say they draft behind larger vehicles to save fuel. This last one is a dangerous practice, though, and we can't recommend it.

For the 59 percent who are not willing to slow down to save on gasoline consumption, Ford asks how about stop-start technology? The 2013 Ford Fusion is offering EcoBoost with Auto Start-Stop technology, along with EcoBoost only and hybrid and plug-in hybrid offerings. For those taking the survey, they're willing to pay more upfront for green products to save money over time, and Auto Start-Stop adds $295 to the purchase price.

Ford calculates that if just 50,000 customers add the Auto Start-Stop option to their new Fusion, it would save more than 14 million pounds of CO2 emissions and nearly one million gallons of gasoline annually. And it's very easy to use, especially since it's always ready unless you tell it not to engage. When you stop at a red light, your engine shuts off. When you take your foot off the brake, it automatically starts up again smoothly. For a video of all this, see below.

For foot-heavy Americans like myself, stop-start technology is a much more realistic way to save fuel than slowing down to achieve fuel saving and emissions reducing results.

      Can't help but think this devise will become outdated in the next few years, the British Government is in the process of using a new Traffic Light system that "STAYS ON GREEN" permanently all the time, it is basically it is a set countdown LED MPH signals telling you the correct speed you need to be doing to hit a set of traffic lights when they will have changed to green, basically if you doing 30 MPH in a 30 MPH speed limit you will probably hit a lot of red lights, but if you look at a few MPH displays generated by a computer that calculates the speed you need to be doing to hit the next set of traffic lights GREEN, that might be say 27 MPG, and so if keep close to 27 MPH you should hit the lights just as they have changed to green allowing you to go through them green at 27 MPH, then you can speed back up to 30 MPH speed limit. This system will make expensive Stop/Starts systems like this in cars redundant.

        Timed traffic lights is how they all used to be, prior to having the road sensors. Does improve traffic flow. Of course, you miss a light, and you floor it so you make the next, then the ret afterwards (or creep slowly, but which is the one you would rather do?).

      Re-read that first paragraph. You don't what? Think you would slow down? I think you should have probably used the words "I wouldn't" rather than "I don't".

      They said in the video that the start-stop do not work when the air conditionner is on and also when the heating is on. So you have to calculate how often these devices don't work so you can use start-stop option.

        Have turned the key off/on at traffic lights in my two 40 year Classic Fords when its been hot and cold my ignition key works all the time, what ever the temperature. Fords excellent "Aeroflow" system still blows hot air for both temperature extremes, but winding the window down helps a bit when its hot outside, which is not very often in the UK. What are trying to say good old gorr spit it out.

      Those without start stop have no hope. None!

      If you're so juiced on stopping your car at lights, start by turning your car off at lights. If you like the experience, then get stop-start on your next car. It's not necessary to pay $295 to save gas at lights.

        Since the batteries, alternator etc on a normal car are not specified to be turned on and off at every traffic light, you are likely to spend more in maintenance and repairs than you save in petrol. If you want stop/start, you need equipment which is specified with that in mind. Even then I would hesitate to buy the system in, for instance, the VW's, which use an AGM battery, which is not going to last forever doing the job and whose replacement costs are unclear. The capacitor based system in Peugeots and others, which is good for 600,000 stop/start events, would seem a much better bet.

          The Stop Start systems I've seen (and I've seen a number of them) are developed with specific alternator / starter hardware and battery systems designed to manage the increase number of engine on / engine off cycling events.

          Your batteries, alternator and starter will do just fine. You don't need an expensive glass mat battery, but you can get one for less than $295 if you want. Who cares about capacitors? Your starter isn't going to last 600,000 stop/starts, and car batteriers are rather cheap with core exchange.

          @Rotation: Having an adequately specified battery would not increase lifetime in a linear fashion, but by far more than that as the system is not stressed. Your assumptions are rather like saying that if you run an engine at the screaming limit it will only decrease it's durability by 20% from running it at 80%. I suggest you look up the actual specifications of real life stop/start systems, or carry out your experiment and see how long the kit on your car lasts.

          @DaveMart
          @Rotation: Why is it then that every car manufacturer who is making stop/start have upgraded their system, for instance by the use of AGM? Engineers design for a function, and in the case of present starter systems that is to start the car a few times a day, not at every traffic light. 'Although 12-V idle stop-start systems require robust starters or other sophisticated restart systems to operate on this voltage, the battery itself is the primary key to effectiveness. The less capable the battery, the fewer the number of times the engine can be stopped—it’s that simple. The conventional flooded-cell lead-acid battery (FCB) can perform the function perhaps for weeks. ' http://ev.sae.org/article/10667 Try using stop start on your car for a few weeks, and let us know how you got on.

          Both you and the article are supremely uncritical. From the article: 'The AGM has 3-4 times the cycling life of an FCB (traditional battery), so despite its 100% higher cost, the AGM dominates.' So the article says a traditional battery could do your start-stop duty for 'weeks' and the AGM would then do it for months? And yet cars with start-stop go for years without problems. The article is just a gussied up overview of technologies in use. It should not be taken seriously as an explanation of how to employ start-stop or design a start-stop system.

      i was just thinking of a name for a powerful muscle car or suv " FORD LACKATAN" i think a car with a name like that would let the guys go wild girls too check it out hey, just thinking thought i'd share it with you

      Auto Start-Stop adds $295 to the purchase price, well worth the price if you can pass on a little in bit of fuel savings for future generations. Its all about putting some thing back rather than take take its all about me me all the time. Good idea from Ford but a lot of car makers already have it. If Ford ever sold a RWD car that l can buy from them in the UK (which they don't) l certainly would have it fitted. Most folk tend to turn of the ignition with their keys these days at traffic lights in the UK, most are regular route users doing the same journeys you have been doing for the last 30 years, and know the sequencing which traffic lights take longer to change than others. 1.3 million car users gave up on driving the car in the UK last year because they have become to expensive to own, so l am not sure if $295 extra gadget is something most cash strapped buyers will want to pay for, maybe Ford should be looking to add it to all Ford UK cars for free next year as their sales look like they may be about to drop by a third next year as the unlucky "13" number gets put on every British number plate.

      it would save a million more pound of CO2 for all rednecks here who just let trucks idle. ford and chevys all coming out with start stop automatically built in since most americans think rules dont apply to them and we have inept cops who dont enforce any actual traffic laws so built in fuel saving technology is only thing which americans will accept if they have no choice but to be forced to be intelligent. also most trucks will be aluminum for lighter weight. asking americans to do the right thing for future or next gen is like sl*(pping them or speaking some alien language.

        Good point George. I recently stated an intention if I had such a thing to leave a plug in hybrid running the AC just to have a cool work vehicle. Maybe it would be less wastefull than idling a V8 but it makes good sense for us humans not to burn any more energy than we need to.

      Easiest decision in the world. Now we need to get the EPA to give Ford mileage credit for the actual ~5% improvement in real world gas mileage, and get this option available in all Ford vehicles. Imagine the gasoline saved - billions of gallons per year - if it were in the F-150 series and the Chevy Silverado series. 50,000 Fusion users = 1M gallons saved/year.. 5M full sized pickup users - less than 5 years of sales volume - would have us saving 200 times that per years - 200 million gallons per year.

      To me, the most interesting thing about this article is it starts off talking about saving fuel by changing highway driving habits. Stop Start technology is irrelevant in highway driving. Now, if you wanna talk about slowing down in city / suburban driving, Stop Start becomes ver relevant.

      In March I was in Germany. The car I rented was a Mercedes, It had this option. It was fantastic. We need this here in the states.
