I think it is very hard. Even Marco did not make good car simulation in his car tutorial. His car has VERY BAD BRAKING /not like as cars in other games/.

For example, GTA's car has very good acceleration, realistic braking and hand braking.

Did somebody make some expirements on a6 car configuration ?

Is it possible to make cars like GTA using a6 physics ?
