Like the fact that all of these features are in the current bmw´s have driven the F11 5 series and was blown away by all of that seamlessly great working tech!

The Prius does. And even if this system is in an car from a dealer, you can always get one in the aftermarket.

Other gasoline saving methods are :

1. Taking public transportation such as bus or train.
2. Converting to a natural (methane) gas car.
3. Selling your car and getting a 30+ MPG conservative small car.
4. Buying an electric car and commute less.
5. Bicycle to work or school.

CVTs aren't perfect yet. they tend to "slip." But CVTs are getting better and it is the future

[TheGaIaxy]

didn't know an of those technologies mentioned.

BMW did intensive research to find out what gearbox is most efficient, and they came up with the 8 speed automatic. I don't know why there are 9 speeds now...

Just wondering, does cold air filters actually improve MPG? If it does, about how much?

[chucksnizzle]

what about the tornado thing you put in your intake that was big years ago

Step 2: realize that it doesn't have enough range for your daily drive.
They still need more electric charging stations and "bigger" batteries

In a video about ECO start/stop engine, he says that the ECO system saves anywhere between 3-10% on fuel. In this video it is 6-10%. So which one is it?

[ej_tech]

unless your in the Philippines with smoke belching jeepneys and busses

[davidburke]

Nissan seems to have CVTs down pretty well.

[TheCharleseye]

If a regular vehicle goes through 2-3 starters in a lifetime, how many starters will a start/stop vehicle go through?

[davidburke]

But do any cars have a system like that

[NeutralGenericUser]

This is the first thing by Brian that I am disappointed in. You have 8/9 speed autos, but no CVTs on the list? No Hybrids? Come on...

[projectjt]

8 or 9 speed transmissions? How about CVTs?

[FredEFuego]

There is a car that runs on compressed air that is 100% efficient and I wonder why it isn't on the market cough oil companies. Google it and prove me wrong.

Sadly that 60% waste energy number is more like 70% and its a fact of physics and chemistry. An engine that uses burning fuel to do its thing can get 80% at most, what is physically possible.
