Acceleration on Gears
The times show how fast a car accelerates on high gears, without gear reduction. The lower the times, the drive is more relaxing and driver less often needs to change gears during overtaking or hill climbing. Practical tip: if the 60-100 km/h on 4th is higher than 11 sec and 80-120 km/h on 5th higher than 15 sec (or higher than 19 sec on 6th), the car will be felt as rather slowly reacting and will require downshifting very often in road conditions.
In case of automatic transmission the values are shown for the manual mode, if such is available in the car.
Acceleration on Gears
60-100 km/h on IVth gear (sec) (or top gear if total number of gears <4):
10.7
80-120 km/h on IVth gear (sec) (or top gear if total number of gears <4):
14.2

Overtaking Factors
The times show how fast a car accelerates using the optimal gear or gears, in typical overtaking situations. It is an overtaking situations. It is an overtaking with gear reduction or kick-down, the best possible times. Not including the transmission reaction time.
