Powertrain Upgrade

Adds two configuration rows, Engine Power and Top Speed, to every motorized vehicle in the game. Choose them when you buy the machine, or change them later in the workshop. No duplicate machines in the shop, and it works on mod vehicles too.

Seven levels each: Stock / +25 % / +50 % / +100 % / +150 % / +200 % / +500 %. Each level costs a share of the vehicle's own price, so it scales fairly from a small utility tractor to a 500 hp flagship. Power and speed are selected independently – a puller can be all engine and a road tractor all gearing.

The whole driveline is rebuilt, not just the number on the label: the torque curve, peak torque and power that implements read, the clutch torque ceiling, the acceleration limit and fuel consumption follow the power level, while the gear ratios (or the CVT ratio band), maximum forward and reverse speed, clutch engagement, brake force and the cruise control ceiling follow the speed level. On a CVT, only the fast end of the ratio band is stretched, so slow field work stays untouched.

Because these are real configurations, shop and workshop prices, savegame and multiplayer sync are all handled by the game itself. Top speed is capped at 160 km/h.
