Touring cars are 4wd. Assuming you have a tamiya M03 its a fwd chassis so the cornering will not be as exact or as fast. Also most Touring cars are more advanced racing chassis with better suspension geometry than the average FWD mini class car.
Its just one of the things that makes the FWD mini class great fun in its own way. You wont ever match the Touring cars, but the key is to match and beat the other mini's you are racing against.
Brushless is no smoother, in some ways its actually a little more aggressive as it has a lot of torque through the rev-range compared to brushed motors.
