It's familiar to hybrid drivers: Come to a stoplight and brake, and notice the car gets quieter. What's less obvious, until drivers reach the gas pump, is the fuel efficiency.

Originally developed for use in hybrid vehicles, this stop-start technology—which automatically shuts off a vehicle's engine rather than wasting gas idling at a light or in a fast food line—is rapidly being rolled out on everything from minicars to high-performance luxury vehicles. And according to a new survey, it's likely to become the norm over the next decade.

Navigant Research is forecasting that the number of vehicles equipped with stop-start technology will grow from 8.8 million to 55.4 million worldwide by 2022. Based on industry estimates, that would account for more than half of all vehicles produced ..

So I posted to this thread, but it seems to have disappeared...what I posted was that the VW Lupo did this back in 1999:

http://usatoday30.usatoday.com/money/consumer/autos/mareview/mauto497.htm

Quote:

Final quirk: The engine stops running if the brake pedal is depressed four seconds or more. That saves fuel at long red lights and during gridlock. Lift off the brake pedal and the starter cranks the engine up.

EndQuote.Why the post disappeared is a mystery to me??

My concern about switching off my ignition is the wear-and-tear on my start system. If it's too hot outside, I would not turn off my engine.

Already many people are conserving fuel as they drive today. They keep their headlights OFF even though it is raining, they don't replace burned out brake lights, and the won't use their directional signals when changing lanes or turning off the street / highway.

I have a similar technology in my 2012 Chevrolet Sonic LT Hatchback. The 6-speed automatic shifts into neutral (750 RPMs at any stop). It is not noticeable to the driver, except via the RPM gauge. This system maintains the heater, the air-conditioner and the engine vacuum required for the power brakes. In the A/C mode the RPMs increase to 950.

I do wonder what effect this "turn off engine" feature will have on starter motors which are expensive and often difficult to replace in newer vehicles. Also, there is the need to have A/C in the summer in Southern States.

While I'm sitting at that red light saving gas money in my dead car, they better make sure the HVAC is going to remain operational, especially in those hot summer blistering temperatures!

I don't think the engine stays off when there's a demand for A/C, besides, that's really hard on a lead acid battery, I wonder what the cycle depth of the battery is before the engine is made to come on to charge, too bad they don't have regenerative braking like the prius.

Yeah, a hybrid is gonna be the better way to go here, lead acid AGM batteries don't do very well cycle wise, you loose a lot of charge efficiency with deep cycles. Hybrid traction batteries never see deep cycles, I think the prius cycles the NIMH battery less than 15%, and never charges beyond 80%. That and the A/C system is purely electric, no pulley for the compressor, it has a 3 phase hermetic motor driven by a variable frequency drive, and it's operating speed is linear proportional to A/C demand. If you want killer gas mileage and performance, go jetta TDI, if you spend more than 3 hours a day in traffic, go with the prius hybrid. Here in Hawaii diesel is $5.99 a gallon! It's not uncommon to sit in traffic 3hours a day over here, so I went with the prius.

What we need is more technology at intersections. That benefits everyone with one investment.
Really annoys me to be at speed and the light changes, stopping me. Worse, no one else is waiting to go thru the intersection.

I can remember when they were developing this. They were having problems getting the thing to transition seamlessly. Sounds like they've now achieved that. Kudos to them.

Fuel-saving ‘stop-start’ technology to become norm? Stop-start technology—which automatically shuts off a vehicle's engine rather than wasting gas idling at a light or in a fast food line is rapidly being rolled out on everything from minicars to high-performance luxury vehicles. A higher drain on batteries and wear out the starter that much faster. Repair and replacement costs will increase.
There will be more people stalled at the stop sign or stop light with the sound of the engine trying to start......
My vehicle has manual door locks, hand operated roll up windows, all around tinted windows, and wing windows in both front doors. It's Good to Go! No Natural Gas, Ethanol, Electricity, Computer, or Fuel Cell needed for this one....... it's been good to go since day one!
Drive vehicles with high mpg, are very safe, reliable, have a ‘reasonable’ cost and a good ‘value’ for the money.
The price of fuel at the pump is too high!

I've had my prius 7 years and really enjoy this. If you need heat, the engine runs, if the battery is lower in the charge range and you want AC, the engine runs, if you don't, it doesn't and you sit in quiet splendor saving gas. And that technology was from 10 years ago.

And it's really easy to convert to a plugin hybrid too, I put in a 15KW system in mine. Because I'm off the grid in Hawaii, I charge it with pure Hawaiian sunshine, it goes 70 miles on pure electric if you keep your throttle foot off the floor. The island is only 79 miles end to end. In stop and go traffic, the engine never runs, I use about $50.00 in gasoline per month, it really works well!
I ran out of gasoline in Waikiki, and drove 17 miles before I realized I was out of gasoline, but made it home on electric only with room to spare!

There will be more new technology from Formula 1 racing introduced to cars that we can buy. I've already driven cars with KERS, but instead of a speed boost it gives a MPG saving. With the new regulations for the 2014 season, there will be more stuff developed that we will see one day.

It should make a difference for in-city driving. My gas mileage drops driving in the city with the numerous stop lights and occasionally, those long stops for red lights.
