Rather like the chassis tweaks it's difficult to identify the ST200's shorter
gear ratios in terms of straight - line acceleration — you'd need to drive it back - to - back with an ST — and there are actually occasions

gear.

Gears change from second - to ninth -
gear ratios with precise clutch - to - clutch shifting,

Some transmission units also have Winter mode,
where higher
gear ratios are chosen to keep revs as low as possible while on slippery surfaces.
An automatic transmission, also called auto, self - shifting transmission, n - speed automatic (
where n is its number of forward
gear ratios), or AT, is a type of motor vehicle transmission that can automatically change
gear ratios as the vehicle moves, freeing the driver from having to shift
gears manually.
