Engine Sim

Put a finger on the screen and a 660cc turbo kei car wakes up. Slide over to a 4-rotor, a W16 or a racing V10 that screams to 19,000 rpm: 28 engines in all, each one synthesized live from how hard you press.

Start one on the train, in a waiting room or on the sofa, with no car anywhere near you.

ENGINES AND SOUND

- 28 engines: single, V-twin, two 660cc kei turbos, inline-4, inline-5, inline-6, a diesel truck inline-6, boxer-4, flat-6, V6, three V8s, V10, V12, W16, rotaries from 2-rotor to 4-rotor, and a racing V10 to 19,000 rpm

- Every sound is made live, not a recording on loop, so the same rev never sounds exactly the same twice

- The throttle follows your finger pressure: rest it for a soft idle, floor it for a full scream

- Per-cylinder firing, uneven exhaust timing and pipe resonance

- Haptics follow revs, load and shifts. Colour RPM gauge with rev-limiter cut

DRIVE IT YOURSELF

- H-pattern shifter or paddles, switch any time

- A clutch pedal with a real bite point: let it out too fast and the engine stalls

- Practice rev-matching: brake, blip, shift. Nail it and it's silent; botch it and the driveline thumps

- Straight-pipe mode for pops and bangs on lift-off, and a back turbine for compressor surge

TUNE AND SHARE

- Tune each engine with mufflers, intakes, headers, superchargers, cams and ECU maps, and watch 0–100 km/h (0–62 mph), top speed and the torque curve change on the spot

- Chassis tuning shared by every engine (weight, aero, flywheel), plus race clutch, race flywheel, carbon body and race aero

- Share a run as a video with the engine sound, or as audio only

REASONS TO KEEP DRIVING

- Miles from driving unlock engines and parts in the unlock tree, and garage miles keep building while the app is closed

- A Pit Stop summary after each drive (distance, miles earned, personal bests), daily tasks, a login bonus, weekly challenges and a trophy exchange

- A Parts Crate with the odds shown in the app, and invite codes that earn bonus miles

WHO IT'S FOR

- People who love engine and exhaust sounds

- Anyone curious how a V12 or a rotary sounds without owning one

- Drivers who want to practice the clutch and rev-matching before getting behind the wheel

AVAILABILITY

You start with the inline-4 and every core feature, with no ads on the driving screen. Driving earns miles that unlock the remaining engines and parts through the unlock tree. The next unowned V6, V8 or V12 can be rented for 10 minutes after a short video ad, and straight-pipe mode can be tried for 7 minutes the same way. Engines and parts can also be bought with an optional one-time in-app purchase. A one-time purchase removes the full-screen ads shown between engine switches; rentals and mile rewards stay available either way. No subscriptions.

Tip: headphones bring out the fine detail in every sound.
