Here's a rough estimate for comparing acceleration of the BRZ and WRX. As expected, once the WRX hits boost the BRZ never matches it. Still, I was a little surprised to see that:
- The BRZ in 6th gear has more pull than the WRX in 5th until 70 MPH.
- The BRZ has more pull than the WRX when both are in 5th.
- The BRZ has more pull than the WRX when both are in 4th until 55 MPH.
This doesn't account for traction and of course it doesn't take much to increase the WRX's output. Even stock, it'll be 1.2-1.5 sec faster just to 60 MPH.
