Real Engines and Sounds for American Truck Simulator

real engines and sounds mod, ats real engines, ats real sounds, ats mods, ats realistic mods

This mod adds new engines to each of the SCS trucks in game (389, 579, t680, and the w900). These engines are replicated from real life engines, and contain real horsepower and torque ratings. A lot of research went into these engines to ensure that the numbers behind each engine are correct. All the included engines use Kriechbaums engine sounds, for added realism.

In total, he has added 10 new engines (6 Cummins ISX, and 4 Paccar Mx-13) engines to the Peterbilt 579 and Kenworth t680, as well as many classic engines such as the C15, N14, and 3406e engines (for a total of 19) to the w900 and 389. You can edit or add you own engines by using the Engine Editor App that he created (Found in the discussions page of this mod).

Footnote: Please back up your save files before installing new mods, or save to new save slots when trying new mods. This mod is no exception. If you decide to remove this mod at a later date, please visit the "Uninstalling" section of this post.

How Does This Mod Differ From The Rest?

Sensible Engines: Most engine mods just add new engines of various horsepowers to the game. While, they may be realistic engines, many people fail to realize that Horsepower does not matter in this game. Torque is the only performance variable for an engine in ATS/ETS2. There are only 5 common torque options for heavy duty trucks in real life (1450, 1550, 1650, 1850 and 2050). Whats the point of having 30 Mx-13 engines for each truck when only 5 of them will perform differently from each other? This mod adds the most popular engines, and removes redundant motors that are indifferent from another.

Realistic Sounds: Kriechbaum has allowed me to use his custom (and very realistic) engine sounds for his engines. Most engine mods are just that, a mod to add new engines using the default sounds in game. This mod however, uses realistic engine sounds for added immersion and realism.

Attention to Detail: Alot of time, effort, and research went into getting the correct data attached to each engine. Things like Torque rating and curves, horsepower, peak RPM's, engine displacement, Governed RPM limits... you name it, he researched it. Every engine's def file includes links to where exactly he got my information on that engine, to ensure quality.

Engine Progression (Unlocks)

He decided to keep progression unlocks in this mod. A new player (under level 4) will only have engines with 1450 torque available to them. Engines with 1550-1650 torque will unlock at player level 4. At level 8, engines with 1850 will be unlocked. At level 12, all engines will be unlocked.

Engine List

Below is a list of all engines he has added in my mod. Each engine brand below has their own unique sounds:

2017 Mx-13 430 (1550 Ib-ft)
2017 Mx-13 485 (1650 Ib-ft)
2017 Mx-13 510 (1850 Ib-ft)

Cummins ISX (All Trucks)

2013 ISX12 370 (1450 Ib-ft)
2013 ISX12 425 (1650 Ib-ft)
2017 X15 485 (1650 Ib-ft)
2017 X15 505 (1650 Ib-ft) **
2017 X15 565 (1850 Ib-ft)
2017 X15 605 (2050 Ib-ft)

Cummins N14 (w900 and 389)

N14 435 (1650 Ib-ft)

CAT (w900 and 389)

3406e 475 (1650 Ib-ft)
3406e 550 (1850 Ib-ft)
C15 450 (1650 Ib-ft)
C15 500 (1850 Ib-ft) **
C15 550 (1850 Ib-ft)
C15 600 (2050 Ib-ft)

** Engines are left in for compatibility with Kriechbaums engine sounds pack

Differences Between the Engines

Though customization is somewhat limited, each engine type does have its own personality. Each engine type (Mx-13, ISX, N14, C15, 3406e) sounds different from each other, and as close to their real life sounds as possible. Engine size is a real thing in this game, so if you are using Realistic Fuel Consumption, The ISX12 and MX-13 engines will have the best gas mileage, and the ISX15 and C15 motors will have the worst mileage. The bigger theengine however, the better the power ratings (usually). Each engine also has hand crafted torque curves, using real life specifications to further differentiate the engines.


This mod is compatible with all other mods that do not adjust common vehicle sounds (such as brakes, wipers, blinkers etc etc). There is an exception to the following mods:

Coyote's Air Brake Sounds: Place his mod higher priority than this mod.
Coyote's Parking Brake Sounds: Place his mod higher priority than this mod.
Other sound mods may work, but have not been tested.

How to Uninstall

If you ever feel the need to remove this mod, you have 3 options. 

1. Revert to a previous save: Self explanitory. He did warn you at the top of this mod description.

2. Use the Repair Mod (does not always work): 
You can try using the repair mod, but it doesnt work for everyone. It can be downloaded here: . The mod goes in the following folder "/My Documents/American Truck SImulator/mod/"

Basically you need to Remove his Mod and enable the Repair Mod.scs. Load back into your game and you should have sounds. Once you have sounds you can save your game and disable the Repair Mod.scs...

It has also been reported that you need to buy a different engine with the repair mod installed to get your sounds back as well.

3. Sell your truck and buy a new one: After removing my mod of course. Do NOT install an SCS engine prior.


Why is this mod causing the no engine sounds bug when removed?:
In simple terms, this mod is hard to remove because SCS decided to save a trucks Accessory data (sound paths included) in the save file. When you load your save after removing his mod, those old paths to his sound files still exist in the save. This is simply out of his control, and there is nothing he can do to prevent this from happening. You can read an SCS Dev's input on this matter here:
