#1 - Put the rear end up on jack stands and chock the front wheels.
#2 - Start the car.
#3 - Shift into
Drive.
#4 - Put a brick on your accelerator and let it go.
#5 - Make sure you have a spare 10 gallons of gasoline on hand so you can top-off the tank when it starts getting low, so you can do a thorough break-in.
#6 - Wait for the "Low Fuel" indicator to come on.
#7 - Shut off the car.
#8 - Lower the rear end and go get yourself a tank of gas.
#9 - Change your engine oil, differential fluid, and transmission fluid. Admire the glittery appearance of those fluids, because that means that your car is broken in properly.

I'm not saying that this break-in method is for everyone... and really, it could be dangerous if you don't know what you're doing...
...but this is how I broke in my 2010 SS/A6.
