to clarify, what I meant was that the engine max torque output is reduced across the board (i.e. i lower the engine torque curve across all RPMs, hence the reduced torque is generated by the engine whichever gear the engine is in).
In gear-dependent torque limitation, the engine ECU (with input from the gearbox) limits the torque which the engine produces (i.e. 1400rpm Gear 1 gives you 950rpm whilst 1400rpm Gear 4 gives you 1120Nm). the engine max torque is in no way affected unlike the above where the engine is detuned.

Parked in BNDEP as of today. Haven't deployed yet on the roads as far as I know.
There's 3 more new Citaros beside it (can't see the regoes clearly)
Chassis numbers of SBS6860X - SBS6865H and SBS6866E onwards. Note the 20 kg unladen weight difference and big jump in the chassis number. This could very much be the Batch 3 Citaros.

Chassis number difference can be considered...but for unladen weight, there are quite different jumps between regos, like 6845R with 11160kg and 6846M with 11080kg...

Is the unladen weight of a bus chassis really so important?
The B10M Mk2s and Mk3s we used to have and even those B10M Mk4s & VO3xs still running around typically have different unladen weights, varying from bus-to-bus in the same batch. And yet, they're still classified under the same batch.
I can't give you (and 'SBS9C') a definite reason(s) for why the unladen weights differ, but the metal pieces used for building up the chassis in each bus are not all created equal in the first place.
Yes, some will argue that the B10Ms can be said to have different bodyworks which might account for the different unladen weights. But go search on the VO3xs in the same batch and their widely different unladen weights on OneMotoring and you'll know what I mean.

Oh I see, didn't really go through every single bus from the earlier batches, just happened to check SBS6000L, then SBS6860X onwards and found out they are the same unladen weight. Then suddenly SBS6866E onwards had a new set of chassis numbers and lighter unladen weight, which made me thought the new batch is lighter.

the difference in unladen weights could be down to the difference in weight for the individual metal components and related components used to build up the chassis. They typically differ from bus-to-bus, but seems like in this case, those that have the similar unladen weights would hint that they're built around the same time in MB's factory using the same components from a shipment.
typically it's normal to see up to +/- 50kg for chassis unladen weights from what I observed from buses registered here, especially the buses from 1990s. There's some VO3xs that have unladen weights that differ up to 70kg.
But the difference in VIN numbers for the Citaros is a different thing in itself.

Hopefully the DDs after reaching 3999A will continue to use 7730G up till 7999Z.
BSEP Citaros after reaching 6599B maybe jump to 5300C onwards.

I believe the next batch of newly registered Citaros will very likely be heading to BNDEP/CGBP, given the number of Striders that are going to dereg coming 13th May.
Can confirm that SBS6866E onwards are Batch 3 Citaros. Boarded SBS6866E and noticed some differences to the earlier Batch 1 and 2 buses.
Differences observed:
1. Identical patterned flooring throughout the bus (on Batch 1 and 2 the raised flooring uses a different pattern).
2. Interior floor engine covers now have a thick border surrounding it.
3. Lower half of interior glass panels are no longer frosted, but now full black.
Also no DDU is installed. Gearbox is still a Voith and engine still sounds the same.

thanks for the clarification.
another reason why there is weight variation (in the range of + or -50kg) for newer buses may lie in the amount of diesel and/or adblue in the vehicles when they are weighed and registered. as mentioned, a 50kg diference is not significant enough to disclaim major mechanical or even electrical differences across vehicles of the same model.
to also make an extra note, mechanical components built to spec should not have too much variation in weight, and id think weigh the same. i can agree that the weight variation may be due to components from the same batch used in the same buses, although im indulging in the idea that a 50kg in mechanical component weight may be a tad much :P
there are 3 versions of the VIN in use worldwide (ISO, EC, JIS) and all 3 versions are internationally accepted. the change in the Citaro VIN is more likely to suggest a different production batch (within Evobus) that may still be part of the same Purchase Order placed by SBST.

Nope...at least 16 buses are now under Batch 3...

If this is true, it means that they stopped using the sprayed flooring for that portion. That sprayed flooring really looks untidy to me.
I had discussed with the users at SgWiki in relation to the Batch 3 matters; and it occurs to me that the VINs may not be a valid reason to differentiate but the interior difference is.

it all depend on how you wan to separate the batch..
either u take each order of SBST as one batch (i.e 300 buses= 1st batch, 450 buses =2nd batches and 250 buses= 3rd batches), or u want to separate it base on VIN/Internal configuration...
likewise, for the wrights, for batch 2, there is also different configuration...
personally, all regos from 6846 onwards are batch 3.. and for those with new configuartion, u might want to name it as Batch 3B instead...
