I don't need a rocket, but I don't want it to be so slow that it can't get out of its own way. That's part of active safety, and if that protection is missing, I call it dangerous, no matter how safe those big MB bodies are.
We'll have to see.

I consider my NA 300D "so slow that it can't get out of it's own way." But I'm already a mile up in altitude, and I wouldn't dare take the car up I70 west past C470.
Additionally, just based on my experience with gassers, that a turbo engine is every bit as efficient as the NA counterpart. My 280Z with a transplanted turbo engine, even with a 7.4:1 compression ratio and a stock T3 turbine, gets 27 mpg cruising at 80mph. That's every bit as good as it was with the original engine, and it's rare that I hear anyone with that car getting mileage any higher. I wouldn't expect the 617.95x to get any less mileage than a NA 617 (unless you stomp on it regularly.)
