drove the new 1.6 rolla..it is as quick as as 1.8(now dont ask which wins in 1/4).........no power lag..........
best part is fuel economy ..is better .....as far as speed...gear ratios r same.....
so top end is good...though it was a new car..still managed 170plus ..........
but for a normal driver....1.6 economy is a plus point
to decide you have test drive both version......
otherwise u can not feel the difference
