I would hope that any MC/MB engine (and many others) can do exactly that.
Idle is electronically stabilised. If you start an MB ur-quattro and put it into first gear,
it will pull away just on idle stabilisation - the computer wants the engine to do 900 rpm -
it doesn't know you're in gear. On a properly adjusted car, you can get into fourth gear at
around 40 mph without touching the accelerator pedal. If you then simulate "low battery
voltage" to the ISV controller, it accelerates by around 3 mph.

The brakes would have to be _so_ defective that no driver would drive the car beyong the first
block. The brakes don't just overpower the engine - they do so by almost an order of
magnitude. There really is no contest between engine and brakes. Try 0-100 mph and then
