Electronic Throttle Control

I've been told that Mercedes-Benz vehicle's throttles will return to idle when the brake is depressed, thus avoiding the unintended acceleration problem currently experienced by Toyota/Lexus. Does anyone know if this is true?

On my 97 E-420 with electronic throttle, Partially true: Later vehicles may be entirely different

If your stopped NO!. Nice for burnouts.

If your moving, sort of, but it takes a few seconds for anything to happen, and then you get reduced power, but not down to "idle levels"

Did an experiment with my 420 and my duramax silverado (with a +90RWHP tune- 300RWHP, 600lb/ft RWtorque)

On both vehicles I was able to easily brake hard enough under full throttle second gear to invoke ABS. On both vehicles the engine management would kick in after a few seconds of braking and reduce power, but not down to idle.

Although I also believe that on both vehicles if you "pussy footed" the brakes at high speed you would end up overheating the brakes before you came to a stop. You would need to brake reasonably agressively to stop the vehicle.
