Improving the Final Power Rating

[Daggetd]

I was wondering if someone could reveal the way the game calculates a vehicle's power rating.

From what I gather it is affected by Torque, Towing, and Weight (heavier is better). But it would be more helpful to hear any design tricks to get a good power rating.

In my current game, the year is 1957 and the highest power rating I could achieve was two stars. This required an engine and gearbox that gave a one star fuel rating, which is unnacceptable for my standards. And yes, I did make sure to optimize the gearing for the brake specific fuel consumption, so the problem was just the engine itself had garbage fuel consumption. For further information my design skills are at 44, as I started in 1950.

Without showing a bunch of math, I'll sum it up for you:
20% is towing capacity specs. 70% is engine/gearbox torque ratio. 10% is Gearbox Power ratings. 20% is demographics and various "testing."

Towing factors in Engine Torque, low Gear Ratios, and strong chassis designs.

Engine Torque/Gearbox torque. Closer you get to 600ft-lbs the better, Make sure your gearbox supports the torque or there will be penalties. (A 1952 Ford F-8 with a 317 Lincoln Y engine produces 305ft-lbs which would be 35% or 1.75 stars alone)

Gearbox Power rating is the various lower gear ratios, torque support, number of gears and what have you.


Testing is the stuff in Design testing, as well some influence of selected demographic the vehicle type targets (power is not important in microcars so testing won't improve power as much as it would with a truck.)

Cheers for the info, I'll attempt a re-design now. My previous attempts focused on maximising towing capabilities, so it's no wonder it didn't seem to do much. I thought maybe the game was secretly "capping" the maximum tow by using the vehicle's total weight. After all, it doesn't make much sense for a 900kg car to drag 6 tonnes around. You would need a lot of grip.
