    Have you read about the new Audi RS3? 3 injectors? Did i read right?

    I have just read this article and it sounds like there is a lot of Technology into this car! 400 horsepower out of the box this car is going to be a while sought after and huge aftermarket scene I would imagine!
    Here is copy and past (only the performance section) from front page of audizine!

    Behind the impressive performance of the Audi RS 3 Sportback is the world's most powerful production five-cylinder engine - the 2.5 TFSI. It delivers 294 kW (400 hp) of output - 33 hp more than the predecessor engine - and is 26 kilograms (57.3 lb) lighter thanks to its aluminum crankcase, among other features. Its maximum torque of 480 Nm (354.0 lb-ft) is available at engine speeds as low as 1,700 rpm and remains constant up to 5,850 rpm. That's how the RS 3 Sportback is able to sprint from 0 to 100 km/h (62.1 mph) in 4.1 seconds. The effect of this extraordinary tractive power is intensified by the five-cylinder's unmistakable sound, which comes from having the ignition alternate between directly adjacent cylinders and widely spaced ones. On request, Audi will increase the electronically limited top speed from 250 km/h (155.3 mph) to 280 km/h (174.0 mph).

    For better mixture preparation, the new 2.5 TFSI engine employs dual injection into the intake manifold and into the combustion chambers. On the exhaust side, the Audi valvelift system controls the duration of valve opening depending on the throttle and engine speed - for moderate fuel consumption at low and partial load as well as more spontaneous throttle response and a high level of tractive power at full load. In the New European Driving Cycle (NEDC) the RS 3 Sportback uses 8.3 liters of fuel per 100 kilometers (28.3 US mpg), which equates to 189 grams of CO2 per kilometer (304.2 g/mi)

    What do you guys and girls think about this?

    Where did you get 3 injectors from? This picture looks like one for each cylinder still.

    This is pretty super. I would trade an organ for it. Or the A3 sportback TDI Quattro manual. They're both pretty awesome cars.

    Glad to hear they're putting injectors back into the intake manifold. This should solve the carbon problems Audi-Volkswagen and almost all direct injection engines have. I don't think I would every buy any Audi direct injection car.

    2 injectors per cylinder (one each for the manifold and chamber) x 5 cylinders = 3 injectors, how exactly?

    Still not sure where you're getting 3 injectors from? It's dual injected meaning each cylinder has one direct injected into the cylinder and one at the intake manifold = 2 per cylinder = 10 injectors total

    is this to keep the intake valves washed with fuel so that carbon doesn't build up?

    For either that car itself, or that drivetrain in a B6, or another RS model, or, or
    would be nice

    Exactly. All the benefits of direct inject without the carbon buildup.

    How does the injection timing work on the manifold injection? The same way it does in our B6?
