I've driven a mate's WRX just with a big noisy muffler on it, and the micra is HEAPS faster than that car. The power to weight ratio is in a different league to a stock WRX. The micra would blow it in the dry. The thing is, wrexxy owners don't often sacrifice their clutch just to beat a micra in a drag race, its rare that you will find one willing to rev his car to 6000rpm and kill the clutch to beat you off the line etc. If they did that, they would have me off the launch every single time. But by even mid second gear, the micra would be back passing it and then pass it easily. The micra actually launches fairly well mostly because its just such a light car, there's not a lot of lard to move off the line.
In the wet, obviously forget about it. Horses for courses. But in the dry blue monster kills a factory WRX. I kept up with Brendon's GTiR dead equal side by side to about 130kmh when we backed off. His car makes 160kw at all four wheels. Those races were always from rolling starts. Again, if Brendon wanted to waste some clutch, he would blow me off the line every time. And if Brendon did that, I wouldn't be able to come back and pass him or catch up because our car's were dead equal once we have traction! His car is fast!
Plus they handle like a sack of potatoes as standard. bah to that
