The same can be said for the Mercedes... again, two turbos, but with a 5.5 V12 picking up the slack while they spin up. For a big, heavy car, it will really scoot... in fact, it's the quickest car I've ever owned. My first sub-13 second car. Cubic inches AND forced induction is a really fun combination, even worth the 91 octane fuel bill.
The worst case of turbo lag I ever experienced was a rental car in Germany. We had an Audi A4 wagon, with a teeny little turbo Diesel. It had a nasty habit of slumping over a second or two after you launched into an intersection... that was unnerving until I learned to get the RPMs up a second or two before the light changed, just to get a little boost going.
