Well, DI seems to come with some unpleasant side effects for long term reliability, such as carbon build -up. I think i read that Benz is introducing a hybrid DI-port injection system to eliminate the carbon buildup problem.
What exactly is the RS5 engine getting out of the DI? Real world results seem to indicate not a whole lot, if anything at all.
Guys, just enjoy the car for what it is. I just bought track tires and wheels, so I guess I'm going to burn as much fuel as I can...
