Challenger 2 MBT - Technical data and Discussion (Part 2)

I’ve given this a test on the dev server, the mobility definetly feels better, in general the Chally 2 feels like it’s more willing to actually accelerate now where before it was quite stubborn

The top speed and reverse appear to be the same

I see. I don’t think I’ve ever understood exactly how transmissions work in game, but the fact that they changed the highest and lowest gear made me think that would have an impact on top speeds

I also thought that too to be honest, but I think they may set a seperate maximum speed limit for both

If I remember correctly they also tweak one or two other variables, like the sprocket diameter or something. They did that some time ago for the Leclerc (which ruined most of its mobility advantage over other MBTs)

forwards should still be the same 59kph/37mph

Reverse speed has increased from 23mph to 24mph

the acceleration in gear 8 fowards and R4 backwards would have been reduced a lot, but below that increased

they changed other gearing to keep the top speed the same,

if the gear ratio of the top gear got increased by 10% a ratio somewhere else got reduced by 10% to keep the same overall (usually “mainGearRatio” and “sideGearRatio”, of which both serve the same purpose so it doesnt matter what chagnes, but “sideGearRatio” is meant to simulate the final drive

The equation for top speed is this

Ah ok thanks for the info, im kind of out of my depth with gearing stuff

Honestly the high speed acceleration still seems pretty decent, the mid range acceleration does feel noticeably better though

30mph-37mph it should be identical to current, but 25-30mph is severely reduced, as previously there was a whole gear to deal with that range, now its forced into gear 8 for that, where the engine “torque curve” doesn’t provide much torque leading to poor acceleration

I did notice it was a bit slow there, below 25mph should it be better?

it should be, especially on steep inclines

From my understanding, from basically 0 to 20 it should be better. Gears are closer so there’s going to be more « torque » overall.
Can be counteracted tho if there’s to much gear changes (what’s killing the Leclerc and VEXTRA accelerations right now)

wouldn’t be such an issue if automatic transmissions were, y’know, automatic.

they shouldn’t be affected by crew skills, same with Electric/hydraulic/powered traverse systems

we don’t see autoloaders dependant on crew skill do we?

And what would this do in game? More torque, faster acceleration?

Yep. The current « double gear change » method is very limiting for vehicles with very close gear changes and high horsepower.
Especially for a tank like the Type 10 which doesnt have gear changes ahah

better sub-20mph or so, identical 20-25mph worse between 25-30mph, identical at top speed

I don’t think they are affected by crew skills? If they are, make a report or suggestion for it

they are, its the gear shift time, you do really notice it on a stock crew

and turret traverse

have been planning to

What would you have to upgrade? Driver?

whatever the bottom most skill is on the driver, yes

Fun fact, the Leclerc also had the bug that the crew skill did not actually improve gear shift timing for a long time, so it was basically stuck to a 0 crew skill speed, making it even worse at accelerating. I’m not actually sure this was even fixed
