Volvo B10M Mk IV DM's with 4-speed Voith transmissions

SBS2601D SG

The B10M really isn't a particularly fast bus. Its only the DM3500 that has the fwah acceleration.

MKII NAC mai gong la. That one is a rocket with open cock-pit. Especially the ones with WA PS body!

Just took 887J on 156....confirmed now its a 4-speed Voith....the 2nd overdrive took really really long to appear and only at very high rpm exceeding 1.7k.

Nice bus to take....in performance curve, seems to offer better power in the high rpm regions as expected of the higher power available than 893R which I'm accustomed to taking. But as expected also of the lower torque figure provided above, engine lacks the oomph of the THD102KF in acceleration.

You can try taking SBS892T or SBS894M.

I felt they are nice bus to take also

894M ftw!

I took it on one of those express services a few years ago, its 2nd overdrive kicks in much more easily and the bus literally flies on the main road purring as a result.

I dont really like 905R....its acceleration isn't as good...and after taking it, I believe 3 times, I have yet to hear its 2nd overdrive.

I havent tried 892T yet....maybe I'll get a chance soon like my surprise with 887J.

Saw PA7850Y at Bendemeer Rd just now, the rear bumper was missing. The engine sounds like MK4 also

And for the breakdown for the B10M fleet with respective power ratings for each engine:

Volvo B10M Mk I (THD100EC (245 hp)/??) - SBS9C (1) - Vanhool
Volvo B10M Mk II (THD101GC (242 hp)/ZF4HP500)- SBS1696L-SBS1895D (200) - WA 'PS' and DM
Volvo B10M Mk II (THD101GC (242 hp)/Voith 381.4)- SBS582M-SBS875T, SBS878K-SBS881A (298) - DM
Volvo B10M Mk II (THD101GC (242 hp)/ZF4HP500)- SBS876K and SBS877M (2) - DM
Volvo B10M Mk IV (THD102KF (245 hp)/Voith) - SH951M-SH970H, SBS2689B-SBS2838M (180) - Soon Chow and DM3500
Volvo B10M Mk IV (THD101GD (273 hp)/Voith)- SBS883U-SBS889D, SBS891X-SBS894M, SBS903X-SBS906M (15) - DM
Volvo B10M Mk IV (THD102KF (245 hp)/ZF4HP500) - SBS882Y, SBS890Z, SBS895K-SBS902Z, SBS907K-SBS996C, SBS1896B - SBS1999M, SBS2593T-SBS2688D (300) - DM & WA 'Strider'

All the above are -60/-61 buses with 12m/40 ft approx length

Unsure of whether the following two have uprated engines or not:
Volvo B10M-70 Mk IV (14.5m) (THD102KF/ZF4HP590) - SBS997A (1) - DM
Volvo B10MA-60 Mk IV (19m) (THD102KF/ZF4HP590) - SBS998Y (1) - DM

Taking a VIN as an example,

YV31MGC11JA018185 (SBS1840L if anyone is wondering)

The 6th and 7th digits of the VINs of Volvo B10Ms denote the engine type, of which the Volvo B10M Mk2s and 3s have GC; Mk4 DM with Voiths have GD; all other Mk 4s have 2F.

Which I believe EC denotes THD100EC, GC denotes THD101GC, GD denotes THD101GD, 2F denotes THD102KF.

I do believe that the choice of gearbox and the tuning of gearbox does affect the performance of the buses. Also, the same engine model may had slight tweaks over the years, which may account for certain differences. And lastly, every vehicle is different, even if they look the same, and have the same specs, they will still perform differently. So that may explain differences in apparent power throughout the fleet.

All in all, SBS (including SBSL) operated a total of 988 Volvo B10Ms with 7 different engine/transmission combinations and 12 distinct types of buses within the family.

Above information is to the best of my knowledge, do feel free to correct or add on.

Interesting write up. Does the MK3 body have the same weight as the MK4 DM since they share almost the same design?
