Seamless Engine Morphing

Switch from inline to V configurations, alter bank angles, change cylinder counts, and adjust firing intervals.
Every change transforms the engine while it stays running.
Camshafts split and merge, crank phasing shifts, valve angles move dynamically—an entirely new way to experience engines.

Significantly Enhanced Engine Sound

A dramatically improved synthesis engine delivers more vivid firing intervals, clearer cylinder and valve-train differences, and faster response.
Included by default—no in-app purchase required.

Deep Engine Specification Editing

Greatly expanded from the original, allowing more accurate expression of an engine’s character.

・Cylinder count, bore, stroke
・Bank angle, mounting angle
・Firing order, firing interval
・Cam drive (belt / chain / gear)
・Valve train (SOHC / DOHC / OHV / VTEC / Desmodromic)
・Valve diameter and included valve angle (reflected in CG)
・Tire width, aspect ratio, wheel diameter (outer diameter calculated automatically)

Recreate everything from spirited singles to unique 5-cylinder pulses, modern V4 superbikes, and the bold heartbeat of American V8s.

TechTour

A hands-on learning mode evolving from the series’ interactive tutorials.

・Four-stroke fundamentals
・Synchromesh mechanisms
・VTEC and Desmodromic systems

Engines become even more fascinating when you understand how they work.
