Yup... that website does have 2.0 TFSI and 3.0 TFSI...
But then when you choose each of those options, and then look at the Technical Specifications of the car, you get further explanation showing the Turbo vs Super charged

2.0 TFSI Option

• Engine type Four-cylinder
• Displacement (cc)/Bore and stroke (mm) 1984/82.5 x 92.8
• Horsepower (@ rpm) 252 @ 5,000-6,000
• Torque (lb-ft @ rpm) 273 @ 1,600-4,500
• Engine block Cast Iron
• Cylinder head Aluminum-alloy
• Valvetrain 16 valve DOHC with Audi valvelift
• Induction/fuel injection TFSI®/Turbocharged
• Acceleration (0 – 60 mph) 7.1 seconds
• Towing capacity (lb) 4,400 lbs

3.0 TFSI Option
rEngine type Six-cylinder

• Displacement (cc)/Bore and stroke (mm) 2995/84.5 x 89.0
• Horsepower (@ rpm) 333 @ 5,500-6,500
• Torque (lb-ft @ rpm) 325 @ 2,900-5,300
• Engine block Aluminum-alloy
• Cylinder head Aluminum-alloy
• Valvetrain 24 valve DOHC
• Induction/fuel injection TFSI®/Supercharged
• Acceleration (0 – 60 mph) 5.7 seconds
• Top track speed 130 mph 1
• Towing capacity (lb) 7,700

But when it comes down to it... super vs turbo.. they both do "the same thing" with different efficiencies... Lookup Supercharger on web where i read a supercharger driven by exhaust is typically called a turbocharger. They both push air into the engine... Turbo uses exhaust to push more air, while Super uses a direct driven belt (or other mechanical wizardry).

I haven't researched recent changes in technology but in principle a supercharger which runs off engine or electrical power is preferable to a turbocharger which runs off exhaust gas. The reason is turbo lag. It takes a turbo time to spool up. Designers have been cutting that lag time by a variety of tricks but have yet to match a supercharger. My first supercharged engine basin an MB C32 AMG. It felt just like the TFSI feels. As you push the pedal the car just smoothly accelerates, no hesitation. The knock on superchargers is parasitic drag on the engine which costs fuel efficiency. The modern solution is to put a clutch on the supercharger, or disengage and engage it with a solenoid, or make it electric--any of these methods reduces the drag. Trust that Audi knows what it's doing when they use a supercharger. It's just plain the better way to get more mixture in the cylinder which is the objective of both turbo and supercharging--they have the same objective.

Yes, exactly, to achieve the same objective - forced induction=high performance. The two do exactly the same job, but power increase effect is achieved by two different methods - that's all. And I will choose supercharged 3.0 TFSI (I still call it "turbo") over exhaust-driven turbine "turbo" every day. Thus I am not waiting excitedly for an appearance of lesser-capable engines targeting mostly reduction of assembly cost and very minor increase of fuel efficiency.
Differences Between Superchargers And Turbochargers
...And, after driving VW Touareg TDI for almost 5 years, I've become a diesel junkie. I will definitely choose TDI if it will become available in the US again. I've heard a rumor that VAG plans to re-introduce TDI back to the US market in their domestic-built VW Atlas.

Force-1

Love me forced induction since I live at 5400'!
