This app synthesizes realistic engine exhaust sounds from scratch, based on the physics of firing orders and cylinder layouts. Explore various engine configurations, adjust muffler settings, and experience dynamic features like pops, bangs, and flames. It also includes a detailed 3D engine animation and driving simulation elements.

Game Center leaderboards now open, and ten achievements have arrived. • Lap time leaderboards for every circuit and engine are live. Until now the dashboard only said nothing was set up. • Added ten achievements: hearing all eleven engines, a lap with every assist off, a tilt-steered lap, a manual-gearbox lap, passing 250 km/h, and more. • Find them in Settings. Progress keeps accumulating even without signing in to Game Center.
