The best engine building games, ranked by what they actually teach

"Engine building game" covers a lot of ground, from full mechanic simulators to puzzle games with an engine on the box. The question that sorts them is simple: after an hour, do you know something about engines you did not know before?

Car Mechanic Simulator (2018, 2021)

The biggest one. You strip and rebuild whole cars, part by part, and the sheer inventory is educational on its own — you will learn what a lot of parts are called. What it does not teach is order: the game will let you take an engine apart in any sequence that removes the parts on top first, which is sort of right, and reassemble it by clicking the highlighted slots, which is not how anyone learns. Great game, weak teacher.

My Summer Car

A cult classic, and genuinely instructive in the way real life is instructive: put the engine together wrong and it does not run, and the game will not tell you why. That is authentic and also maddening. You learn by failing, which works for the people it works for.

Mechanic Simulator VR titles

Hands-on in the literal sense, which helps with spatial understanding — where the oil pump sits relative to the crank is easier to remember when you have reached past one to get to the other. Most are shallow on the engine itself, deep on the feeling of being in a garage.

Automation

Not an assembly game: it is an engine design game, and the best one there is. Bore, stroke, compression, cam profile, turbo sizing, and a real-enough physics model that shows you the trade-offs. If you want to understand why an engine makes the power it makes, this is the one. If you want to put one together, it is not.

Bore and Stroke

Ours, so weigh this accordingly. The idea was narrower than any of the above: teach the order. Every part in the tray belongs to the engine — there are no decoys — and the only question is whether this part goes now. The game refuses a part that would seal another one in and tells you why, the way a mentor would. The blueprint shows through the assembled block, so you learn where things live. More than 200 engines — cars, motorcycles, trucks, tractors, locomotives, small engines — each a different sequence, because each is built from its own specification. Then a dyno, because the point of an engine is the number.

What it does not do: model the running engine in depth. For that, the tune simulator on this site is the companion — and Automation, if you want to go further.

The honest ranking

For learning what parts are called: Car Mechanic Simulator. For learning why an engine makes power: Automation. For learning how one goes together, in order: Bore and Stroke. For an afternoon in a fictional Finnish garage: My Summer Car, with patience.
