[quote author=Somorin#1]Okay, you missed the transaltion.

The author, like me knows Audi for turbocharging their engines. He said this is the first tiem he os driving a turbocharged Audi. He did not say that the Audi has both turbocharger and supercharger. Read it again.

Edit:

2012 Audi A7 3.0T Quattro supercharged 3.0-liter V-6 engine

Source: http://www.caranddriver.com/reviews/audi-a7-review-2012-audi-a7-sportback-first-drive[quote author=Somorin#1]Please provide your source. The A7 is Supercharged but not Turbocharged also.

Turbo fuel stratified injection (TFSI) denotes a type of forced-aspiration ("turbo" engine where the fuel is pressure-injected straight into the combustion chamber. FSI (VAG) direct injection technology increases the torque and power of spark-ignition engines, makes them as much as 15 percent more economical and reduces exhaust emissions.[1]

http://en.wikipedia.org/wiki/Turbo_fuel_stratified_injection[/quote]There's going to be a TurboCharged V8 to be released soon but it's not what you're selling so don't confuse your buyers. Very few road cars will offer both forms of forced induction due to realiability. Talk about a high stress working operations.[/quote]Now you are convinced and have admitted to know that the Audi A7 is Supercharged. The author also admitted he was driving a Turbocharged Audi which was related to the 2012 Audi A7.

I don't understand what more you want me to show you.

The Turbocharged V8 to be released is for the S7, and S8 and NOT the A7 (and has been released in 2012)

http://en.wikipedia.org/wiki/Turbo_fuel_stratified_injection[/quote][b]Driving the A7 can be almost as arresting as staring at it. My test vehicle was the A7 3.0 TFSI quattro Auto Tiptronic Sedan. This was my first time driving one of Audi’s supercharged engines. Audi, and corporate overlord Volkswagen, have made the turbocharged engine their bread and butter. The difference between turbocharging and supercharging is simple: a turbocharger boosts engine air pressure by using exhaust gas to power a turbine that pushes more air into the combustion chamber. A supercharger uses a mechanical connection to the engine to do the same thing, in essence. The difference in operation is that the turbo has to wait until there’s enough exhaust gas flowing in order to spool up and deliver boost; the supercharger can be working whenever the engine is spinning. The big job for turbo designers is combatting turbo lag — the delay between the demand for power and the delivery. Audi has done a good job of taming their turbos over the years, and seems quite devoted to the technology, for good reason. In theory, turbochargers are almost like free power — they transform some of the engine’s wasted energy into action. Superchargers, on the other hand, deliver their increased boost with a penalty, because they get their motivation from the very engine that they’re trying to help out. The supercharger’s advantage over the turbocharger is a very linear delivery of boost, and lower operating temperatures.

A7′s supercharged engine comes on like a freight train. Push in the throttle and the thing just goes, getting stronger with each passing second. The rush is compelling and addictive, even though the figures from the 3.0-liter V6 aren’t overwhelming (310 hp/325 lb-ft of torque and 0 – 60 in 5.4 seconds). The eight-speed Tiptronic transmission slips through the gears seamlessly, with the center console-mounted gearshift providing sequential manual access to each cog. Audi’s usual great braking, steering, suspension and quattro all-wheel drive deliver a confidence-inspiring ride that is remarkably quiet and serene, with the potential to achieve 18 mpg city/28 mpg highway (according to the EPA).[/b]

vet707: You definitely got a MACHINE there! Undoubtedly delectable!

[quote author=Somorin#1]I doubt that and ask you to verify your merchandise.

Good luck.[/quote]
Thanks to exceptional engineering, the all-aluminum 3.0-liter Audi TFSI® engine with direct injection and supercharging delivers the potent acceleration of a traditional V8 with the efficiency of a V6. The result is improved mpg and an increased heart rate.* - Audi
