|Defines the number of strength levels for the engine brake. The braking torque at each position is based linearly on the number of positions. So for <code>engine_brake_positions: 3</code> the first position will have <sup>1</sup>&frasl;<sub>3</sub> of the full strength, the second position will have <sup>2</sup>&frasl;<sub>3</sub> of the full strength, and the highest position will have the full strength.

|auxiliary_brakes
|array&lt;float3&gt;
|
|When set, this overrides the engine brake control so that it controls both the engine brake and retarder (if present). The components are (engine brake strength, forced downshift, retarder strength). The value of '''engine_brake_positions''' must match the number of members in auxiliary_brakes. (''Added in 1.40'') For example:
<pre> engine_brake_positions: 5
auxiliary_brakes[]: (0.3, 0, 0) // 30% engine brake only
auxiliary_brakes[]: (0.6, 0, 0) // 60% engine brake only
auxiliary_brakes[]: (1.0, 0, 0) // 100% engine brake only
auxiliary_brakes[]: (1.0, 1, 0) // 100% engine brake and downshift
auxiliary_brakes[]: (1.0, 1, 1) // 100% engine brake, downshift and 100% retarder</pre>

|volume
|float
|0.0
|The volumetric displacement of the engine in liters. It is used in base fuel consumption calculation, engine mass & inertia calculations, and also default '''resistance_torque''' calculations eventually. Minimum acceptable engine volume is 6.

|consumption_coef
|sound
|string
|"/sound/truck/engine.bank"|Path to the truck [[Documentation/Engine/Sound/TruckEngine|engine sound bank.]](format like "/sound/truck/engine.bank")
{{Note|The default engine bank has been removed (1.38+). You must explicitly specify a bank from one of the base game vehicles, or specify your own bank.}}
|-
|sounds
|array&lt;string&gt;
|
|Each item assigns an FMOD event to an engine function, using the "''<nowiki>sound_name|sound_path</nowiki>''" [[Games/ETS2/Modding_guides/1.39#Accessories|format]]. ''Added in 1.39''
 
Expected sound event names are: engine, exhaust, start_bad, and turbo.
