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
12 3D models: Inline-3 Lightweight, Inline-4 High-rev, Inline-4 Hot Hatch, Inline-5 Rally, Inline-6 Silky, V6 Wide-bank, Flat-6 Circuit, V8 High-rev, V8 Muscle, V10 Supercar, V12 Grand, 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. Cutaway and visual-only slow view work on the main and expanded screens; sound and engine speed stay unchanged. Choose from four backgrounds. 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, braking 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. Inline-4 Hot Hatch: revised sound, Crackle by default, Stock selectable; optional intake/boost sounds. Turn on pops & bangs to hear it. Preparation screen, saved-tuning compatibility and setup messages.
• Ads and access
Start the default inline-six engine without watching an ad. Other engines can be previewed while stopped; a rewarded ad is offered when you first try to start one. A confirmed reward grants 24-hour access to that engine on this device. Press Start again after the ad closes. Passes are saved separately for each engine. Expiry does not interrupt an ongoing session, but returning to or reopening the app restores the default engine if the pass has expired. The default engine remains available if an ad cannot open or a reward is not confirmed. 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.
The graphic and the simplicity of controls is just amazing! But I particularly have a problem with the gearbox. It is too fake, like the first and the last gear are just the same and you cannot find any difference between revving the engine in the first and last gear! But overall, I liked it…
Developer Response
Thanks for the detailed note. Right now the app is an engine on a bench: there is no vehicle load, so free-revving sounds the same in every gear. Gear-dependent load is on our list, and your review helps us decide how to do it.
Awesome

This game is awesome. The videos and ads about it are real, but one thing I don’t like is I have to watch ads to play with the engine for only a day I think that the engine should be always available and one engine that should add is a rotary engine.
Developer Response
Thank you. Each engine stays open for 24 hours after one rewarded ad, and if no ad is available it switches right away. A rotary engine is in the works. No date yet, but it is coming.
Game is great
Cold vs hot
This is a good game but fix the sounds please they are realistic but not enough and make it to where you can switch through kmh to mph please but I love the game

Improved guidance for retrying an ad or returning to the default engine when an ad cannot load.
