http://www.eurocarnews.com - Volkswagen AG - The most effective means for reducing fuel consumption is so-called downsizing. By reducing displacement and thereby lowering frictional losses, a lower specific fuel consumption can be achieved, and this goes hand in hand with better efficiency. The innovative path to the future is the combination of supercharger and turbocharger. The supercharger compensates for typical drive-off weakness at low revs of purely turbocharged gasoline engines, while the turbocharger really puts out at higher revs. This combination of two types of chargers is unique among engines mass-produced worldwide.
Only FSI technology came into consideration as the injection technology; in the meantime this has become a technology implemented by Volkswagen in numerous car model series. Based on experience acquired by engine developers over the past several years with this injection technology, it was recognized that FSI would be ideally complemented by two different charging technologies and enable previously unheard of efficiency gains. In spite of significantly better driving performance, fuel economy is improved by about 10 percent relative to a comparable naturally aspirated engine.
@WickedTRX Yes you are in right, but I see that coolant pipe go around engine block so think that use engine coolant, cool thing, always see air inter-cooling on car, I'm not prefer any blower so that not ides that there is different type of cooling air , hmm... why don't make cooling from AC compress then can theoretically make more richer mix A/F :D

@FuriousHondaBoy I wouldn't call it an innovation. many cars have it. ex: Ford GT, mid 90's celica gt4 and subaru impreza. They have a totally separate cooling system, nothing is shared, if it used the engine coolant it would be heating the intake air instead of cooling it, try sitting in a car with engine at normal operating temp, windows closed and heater at max. The chargecooler operates in the very same way as the heater, but the air is hot, and the water is at ambient temp.

@WickedTRX thanks, I didn't know for that innovation, it's cool :)
So, is intake air cooler have yours independent cooling system or take from engine coolant ?

@FuriousHondaBoy It's water, the engine does not use a conventional intercooler, instead uses a chargecooler, it has a dedicated water circuit, with it's own water pump and radiator, it cools the hot air coming from the turbo. main advantage is packaging of the intake piping keeping it tidy and shorter.

wtf is green fluid ?!

@urbex2007 Cause modern diesel is very fragile to bad fuel quality. Turbochargers break and are very expensive to replace or repair. Actually every part of diesel is expensive. Petrol engines have more fuel consuption, but are way cheaper to buy and repair. If you don't drive much it's better to buy petrol engine, because repair costs of diesel may kill all the benefits from lower fuel consumption.

This is nothing new, Mitsubishi did this in the past. Unless you make each cylinder SMALLER the car will use the SAME amount of fuel no matter how it is injected. Vauxhall copied SKODA/VW by having small turbo engines, but they are rubbish. Stick to SKODA/VW with the DSG gearbox. Go for this engine only if you like it to sound like a diesel, or if you want real economy - just buy a turbo diesel. You get double the mileage and more power with less CO2 emissions. Why use petrol anyway!
