More New Cars Will Have Start-Stop Tech by 2016

Start-Stop Tech - Chevy Malibu

Start-stop systems — a longtime integral attribute of hybrids and, in the past few years, something offered on luxury models from BMWs and Porches — are about to get a lot more popular, according to Johnson Controls, a major auto supplier.

Auto start-stop systems, which cut off an engine’s fuel supply when the car is stopped, were in about 8% of new cars in 2010; they will increase to 52% to 55% of new cars by 2016, according to the parts firm. The quick adoption mainly stems from increased pressure on automakers to increase fuel-economy standards from a 30.1 mpg average to 35.5 mpg by the federal government’s 2016 deadline.

Auto-start stop technology can increase fuel economy by 5% to 12% compared to a model with a regular gas engine. The change is already happening today. Vehicles like the Chevrolet Malibu, Buick LaCrosse, Buick Regal, Kia Rio and BMW 5 Series will get the technology in the 2012 model year. Mazda, Audi and Mercedes-Benz are working on similar systems.

1 caution here 'bou start-stop technology that no one seems to dig deeper into understanding it - how it works.

Unlike hybrids with SST, you need to actually know when SST will kick in, if vehicle equipped, in order to achieve the fuel savings. Kinda like driving feather foot to achieve best EPA mpg.

It works when you actually come to a complete stop, for over 5 sec (I think). Stop light traffic is one. STOP SIGN traffic is NOT. Fwy traffic jam is most likely NOT (you are most likely driving at less than 5 mph, or stop for less than just a few seconds, rather than complete stop > 5 sec). Most importantly, if you've climate control on, forget 'bou this. Thus, looks gr8 on paper and definitely a way to meet emission legislation, but quite difficult to achieve the result in reality for pure ICE vehicle.

Good technology, but limited application - more suitable for hybrids, or those who can adopt to green driving on pure ICE vehicles.

So, if I understand this correctly, if your at a complete stop in a I95 Traffic Jam in the dead of Summer here in Florida, your engine AND your A/C shuts off, right? How sweet! Also, is there not going to a lot of extra wear and tear on the electrical system and engine starter with this constant restart of the engine.. just saying. I for one will give up the extra 1 mpg savings, enjoy my comfort and avoid the expense of future mechanical repairs which I`m sure will follow once the Warranty is over.

@ HJ,

"is there not going to a lot of extra wear and tear on the electrical system and engine starter with this constant restart of the engine"

The answer is no, unless u r trying to mimic the same thg on a vehicle w/o SST. See Click & Clack's explanation in cartalk.com.

Rockaby,

Nice catch! PORCHES!! XD

The price of gas continues to be ridiculous. Features like this will certainly help. Until then, it's important for consumers to do what they can to cut down.

I would like to see this feature on all cars as a standard option (like driver airbag).

Its an awesome post. Good to see this post. Thanks

Nice post with useful information.
