Just as good as the others
By BHW on
2008 Audi S8 quattro 4dr Sedan AWD (5.2L 10cyl 6A)
To say that the S8 lags behind the other luxo-cruisers is only revealed by a few clicks on the stopwatch. In real world application, with its 4x4 drive system, I have found the S8 to be far - vastly - more confidence inspiring than the others. You never feel at the limit or out of shape in the S8 as it seamlessly governs oversteer, understeer and anything else you can throw at it. When I drive the S Class extremely hard, I can get it inside out such that the ESP feels confused. I would even venture to say that in the canyons near SLC, I can drive the S8 faster than its competitors. Its limits are just far more accessible than with the others.
That said, having come from a Porsche GT3 as a daily driver, I still want 4.5 second speed. Even if the S8 doesn't get rolling until 50+ mph, I still like neck-snapping speed off the line.
