thanks to @Ai'Torror (for base DT35 jbeam) and @RELYT2012 (for 4BT torque curve)
So here it is, the Wentward DT35SE... This kept on selling until 2007 due to some cool new upgrades...
1) It is lighter, like 3 tonnes lighter (unrealisticly so, but i'm trying to simulate an enviro 200 kind of bus here with minimal jbeam )
2) It is quieter in the real world (the 4cyl engine irl is quieter than older 6cyl counterparts)
3) It has lower emissions the engine helps a lot here...
4) It saves fuel, the big reason why.. the 4cyl engine is more efficient than the 6cyl
An idea of the performance involved:
4.5L Torque Curve:
There is now a NEO variant of the bus:
Has the 3.0 ETK Diesel engine, along with the 8 speed automatic, it is available in
now T240 as i felt the T220 lacking torque too much.. and T280 variants, it feels distinctly more car-like, and the gearbox is responsive, sport mode is implemented here, and is used for engine braking (and manual mode too)
Allison reprogrammed for the ETK is available too
1)Jiggly railings inside the bus, i know this is an issue, it was a thing on the base DT35 and me changing the weight has made it a bit worse.. If Ai'Torror will update his mod, i'll update this one
2) It sounds like a normal wentward, yes, i don't have a 4cyl cummins soundtrack.. if anyone has then that would be amazing..
3) It is slow/underpowered, i'm going right after the Enviro 200 here.. 35ft long, 9tonnes or thereabouts, and 250hp (well this has 240hp but go figure), the real life one has 1000nm of torque i think, but this makes do with 860nm, this is because it's the 4cyl here, not the 6cyl.. there would be little point in doing all this just for a 6cyl.)
Standard affair of configs, but with the 4cyl engine (safari, base, city, zebra, you know the drill!)
City Maxi: This has the 8.9L diesel engine, which allows it to climb WCUSAs hills at speed, this allows a reasonable amount of fuel economy, without having to resort to expensive unreliable hybrid technologies!
Highway Maxi: This again has the 8.9L diesel engine, and is tuned to have a very low RPM at cruise, good for long journeys, and the torque from the 8.9 will easily push this 9ton bus up long high-speed hills
The new engine in the DT35 really sets it apart from the older buses, it's noticeably quieter, and the allison automatic is smoother compared even to the 6-speed unit in the DT35, acceleration is smooth even when at wide open throttle, however we do find the 4cyl unit to be lacking on power at low revs, and to get the transmission revving, you really need your foot hard down, we think this is the future of buses, as we say farewell to the big torquey engine of past.. However the fuel economy is really good, and if we are comparing it to the more cost effective 270hp DT35, then performance has improved noticeably too! It meets Euro 4 emissions standards, thanks to the 4cyl engine and light weight, but we would like to see a design refresh in the future, the DT35L did look rather vintage in the late 90s, and this is set to be sold until the late 2000s!
Beta Wentward DT35SE (NEO) 2.21
3tons lighter and a new engine-gearbox, enjoy :)
