V2 on 4 engine aircraft is based on losing one engine at a critical point in the takeoff, this point is defined as V1 or VEF. I do not know of any commercial airliner that operates on the premise of 2 engines failing at that critical point.
Jim Modey should look closely at the VMCA2 of a 4 engine airliner and then read the accident report of the EL-AL B747 flight from AMS.
I would be extremely surprised if the CAA allowed for a re-definition of V2 to satisfy Concorde!
