Roller drums have much lower rolling resistance than treads, and he might have better aerodynamics though I can’t tell. Since rolling resistance is proportional to weight, you’re taking a hefty penalty for those treads.
Also, 2 enhanced engines have 1.6x as much power as a single enhanced engine, while 7 engines have 2.8x as much power as a single enhanced engine. That’s how CDDA has always handled multiple engines, so there’s no change there, but you’re burning a lot of juice for not a whole lot of extra power.
Things that will help:
- use aerodynamic designs with halfboards up front, followed by windshields
- try to avoid having full boards and aisles on the same vehicle, especially on the same column as a turret because that raises your vehicle height.
- narrow designs have less air resistance than wide designs - though the penalty for the 6-11th tiles is a lot less than the first 5, so there’s not as much payoff there.
- armored wheels, rollers, or standard wheels give better performance on roads than treads - though your off-road performance may suck
Sadly, any realistic performance calculation is going to make massive, multi-engined mega-vehicles burn energy like crazy without necessarily going very fast.
One thing that would probably help - and that I support but may have problems getting merged - is providing REALLY LARGE engines. A M1 Abrahms tank doesn’t have 5 diesel v8s, it has a single 1500 HP turbine. Fuel consumption is still awful, but not nearly as bad as 5 diesels would be.
