Hi,
I'm currently trying to design a circuit using an Arduino Uno to two 12V DC motors via MatLab using an l293DNE to control them both bidirectionally.
The picture attached is the same setup I have, however with a 12V power supply attached to the H-Bridge so that it is not connected to the Arduino in anyway.
My question is, with a 12V supplied to Vcc2, will both the motors be able to run to their max capacity without the need of a Motor Driver to handle the current.

I don't see Vcc2 marked on your image so I don't know what you mean.
You cannot run ANY motor without a motor driver. An Arduino is completely incapable of providing the current required by a motor.

Did you connect the grounds? (The black wires in the supplied image.)
Please don't post pictures of a setup you don't have. A pencil sketch badly photographed with a phone is preferable to an image with the description "I don't have ..."
