It's just a matter of improving performance. A6 has to do some collision detection calculations for the models and once it's done the model gets replaced with something else and the calculations have to be done again. That reduces the startup speed.
Other than that, be careful when adjusting the car's parameters, as these can have a major impact on its behavior. For example you've increased gravity, doubled the car's weight and put a huge amount of drag on it. Try going back to the default settings and make smaller adjustments- it is mostly trial and error to get the behavior right though.
