Why is the T1E1 5.3 and the M6A1 5.0...?

To add to this, I’ll also point out the datamines that exist, for example, on the T1E1.

T1E1 datamined transmission


That’s it. That’s the transmission. There’s nothing there at all indicating that is electric or anything special. And all transmissions looks like that, except for the ones that don’t have neutral steering, in which case the “neutralGearRatio” value doesn’t exist.

For all intents and purposes, electric transmissions/drives just work as reversible transmissions in WarThunder, at least for now.

Disagree with you should both be 5.0 BR

M6a1 has better turret traverse also
