The overall ratios from gearbox input flange to steering unit output flanges, including therefore spiral bevel reduction on the gearbox output shaft, are:
8th .98-1
7th 1.61-1
6th 2.11-1
5th 3.16-1
4th 4.86-1
3rd 7.15-1
2nd 10.2-1
1st 15.4-1
The four ratios of reverse correspond to, but are lower than, the four lowest forward gears.
FINAL DRIVE
The final drive assemblies are bolted directly to the hull from the outside and contain two stages of reduction.
(a) A straight spur reduction, and
(b) An epicyclic
The steering unit output shafts drive the small pinion of the spur reduction which meshes with the large pinion. The large pinion is mounted on the same shaft as a smaller pinion, which is the sun wheel of the epicyclic reduction on which the planet carrier mounts the driving sprocket, and the annulus is rigidly secured to the final drive casing. The overall ration is 10.55 to 1. Each final drive casing, which is a steel casting, has its own drain plug and filler plug, and a third plug which gives the correct oil level. Oil capacity 8 litres (14 pints).”
Even though its powertrain systems might not have been the most reliable, when they worked the Tiger was quite mobile for its size and weight. It could pivot in place, completely turning around in a distance of 3.44 meters (11.28ft). As the table below shows, the Tigers speed was comparable to other, smaller German tanks except for the Panther:
Model On-road Speed Off-road Speed
Panzer III 40 km/h 18 km/h
Panzer IV 40 km/h 20 km/h
Tiger I 38 km/h 20 km/h
Panther 46 km/h 24 km/h
