All good questions. Good, difficult to track down questions. ...
I'm not sure if there's a drivetrain loss associated with the choice of FWD, RWD or AWD. You'd have to look at the Vamos code.
I believe the torque curves should be measured at the crankshaft, but I'm not sure. The torque curve numbers are Nm. The torque friction is in percent (0.03 = 3%).
Max-power is in watts. Peak engine RPM is where max-power occurs. Max-power and peak engine RPM are used to generate a torque curve if you don't specify one. Peak engine RPM is also used for placement of the red-line graphic whether or not you specify a torque curve. I realize that's silly, but no one has noticed yet, and soon we'll have custom gauges anyway. :-)
Fuel consumption is calculated with the following equation:
Code:
m_fuel_consumption * m_rotational_speed * m_gas * time
Rotation speed is in radians per second. Gas is the gas pedal position. Fuel consumption is from the car definition file. Units are whatever the gas tank capacity units are (probably liters).
In general, to help find out what these settings do, look in vamos/body/Car.cc function Car::LoadCarDefinition. This will show you how the car's classes are manipulated based on the settings in the file, and you can then track down how those classes use the values.
