6th gear ratio is not too effective in 1.6l car.
one needs a torque engine to effectively use so many gears.
this reminds me of toyota trueno blacktop engine 6 speed car.
after testing by professional drivers, they concluded car needs to be a high speed for long time to make use of 6th as final drive... that is if someone drives at 180km/hr for pretty long route
if car is loaded or going slightly uphill, engine will require downshifting..
5 speed forward requires less downshift from 5 to 4.
the 5th gear of 6 speed transmission has diffirent ratio compared to 5th gear of 5 speed transmission in trueno.
corolla 1zzfe ,(known as altis,, 5 speed was well designed setup.
lets see what strategy toyota uses to sell 6speed corolla, i hope its with lsd.
