Engine Simulator 3D

Start the engine and move the throttle to hear and see the revs change. Explore inline, V and rotary engines in 3D.

• A range of engines

Explore Inline-3 Compact, Inline-4 High-rev, Inline-4 Turbo, Inline-5 Turbo, Inline-6 Twin, V6 Even-fire, V8 Low-rev, V10 High-rev, V12 Grand and Rotary Twin-rotor. Drag to rotate the engine, then open the expanded view to inspect moving parts such as pistons, connecting rods, the crankshaft and rotors.

• Views and close-up inspection

Choose a top, side, front or default view, and use two fingers to move or zoom the view. In the expanded view, you can slow the motion down 12× or see through the fixed parts to watch the parts inside, while the sound and revs stay at real speed. Piston engines also show the combustion glow and exhaust heat.

• Four gearboxes

Choose a 5-speed manual, 6-speed manual, 8-speed automatic or 7-speed dual-clutch. Use the gear controls and clutch, brake and throttle pedals for the selected gearbox. Follow the engine state on the tachometer and gear display. With a manual gearbox, revs build more heavily in higher gears and you can feel the lever engage each gear. The clutch pedal shows engaged, slipping and open zones, and you can turn on a large shift lever in Settings.

• Drive modes and launch control

Comfort, Sport, Sport Plus and Custom drive modes change the throttle response, automatic shift points and exhaust valve sound. For Custom, choose throttle response, shifting and exhaust valve separately in Settings and save them. Sport Plus also offers launch control.

• Exhaust and sound settings

Change the exhaust and tuning in Settings and compare the sound from idle to high revs. Audio is generated in real time from the engine's behavior; it does not play recordings of real vehicles.

• Ads and access

The default inline-six engine is available without watching an ad. A confirmed rewarded ad applies the selected engine and gives that engine a 24-hour pass, stored on this device. You can keep using the current engine if its pass expires during use. When you reopen the app or return from the background after expiry, the app switches to the default engine and lets you know. If an ad cannot load, you can retry, check connection help, or keep using the current engine. Banner ads may appear at the bottom of the screen.

No account or sign-in is required. The app interface is available in 17 languages, including English, Korean, Japanese and Chinese. The engines are original designs and do not reproduce any specific manufacturer or vehicle.
