The BBW and DBW should be seamless to the driver and function the same as if they were manual. The BBW on the Guilia does need some work in that area.

I think the DBW (probably more accurate to say throttle by wire) on the Multiair engines is pretty interesting. It uses a combination of the throttle plate and variable valve lift to control how much air is available to the engine. The system works fairly seamlessly to the driver with the position of the accelerator determining the percentage of airflow to the engine just like a manual throttle would. I've also driven some pretty terrible throttle by wire cars, so not all systems are equal.
