RevLab - Engine Simulator

RevLab runs the engine for real.

It computes the crank, pistons, valves, combustion and exhaust gas flow in real time, and that one simulation drives the sound, the haptics, the gauges and the 3D engine. Nothing is animated just for the screen.

■ NEW: JET AND RADIAL ENGINES An airliner high-bypass turbofan, an afterburning fighter turbofan and a nine-cylinder radial that turns a propeller. Spool-up and light-off, fan tones and buzz-saw, jet roar, the afterburner lighting up, the radial's short stacks and propeller: all from the same physics. The volumetric plume forms shock diamonds from the nozzle pressure ratio, and the afterburner flame lights the dark studio. Work a 3D thrust quadrant, a fighter throttle with an afterburner gate or the radial's throttle, prop and mixture levers, and read airliner glass displays, fighter analog gauges or a glass MFD, or vintage dials.

■ DRAG STRIP Quarter mile and 0–100 km/h on a timing strip over the engine stage: no road, no car. Stage on the Christmas tree, hold the revs with launch control, shift on the shift lights. Shift grades are only labels: the time comes from the physics alone. Race your personal-best ghost or the factory driver, study the time slip and post to Game Center leaderboards. Everything but the leaderboards works without Game Center.

■ SOUND THAT IS COMPUTED Cylinder count, firing order, crank geometry and exhaust manifold shape the sound: the uneven burble of a crossplane V8, the scream of a flatplane V8, the rumble of a flat-four on unequal-length headers. Cranking, idle, the limiter, lift-off and stalls all come out of the simulation. Listen to cars from five positions, from the driver's seat to a measurement mic.

■ 14 ENGINES, 2 CYLINDERS TO JET POWER 45° V-twin; inline three, four, five and six; flat-four; crossplane and flatplane V8; V10; V12; V16; and the three aircraft engines, each with a look of its own: cover colors and shapes, intakes, header alloys. Every spec in the Garage is computed from the engine data the simulator runs, and each car engine arrives in a car and gearbox that suit it.

■ DRIVE IT YOURSELF A 3D gated shifter and three pedals. Dump the clutch and the engine stalls; shift without it and the gears grind. One tap on START starts the engine, another switches it off. • 6- and 5-speed manual, 7-speed DCT with 3D paddles, 8-speed automatic, 6-speed sequential • Auto clutch: OFF, LAUNCH, SHIFT or GUARD • COMFORT, ECO and SPORT drive modes on a 3D dash button change throttle and shift points for real

■ GAUGES AND FOCUS VIEWS Four car clusters from stepper-motor analog to 12.3-inch TFT, with day and night lighting. F1 Combustion shows the cylinder cutaway and the pressure–crank-angle trace, F4 Exhaust the pressure waves in the header, and STROBE freezes the cycle like a timing light.

■ FEEL IT (iPhone) Core Haptics delivers engine vibration, clutch bite, gear engagement and grinds, the limiter, and the detents and gates of the aircraft levers, the moment you hear them.

■ EASY ON THE BATTERY RevLab draws only what changes, lowers the refresh rate when you let go and caps it at 60 Hz in Low Power Mode. Settings › Display › Frame rate: Auto, 120 Hz or 60 Hz.

■ FREE AND REVLAB PRO Free: five engines (inline four, inline six, crossplane V8, airliner turbofan, radial), every gearbox, clutch mode and cluster, the drag strip, focus views, STROBE and haptics. Sound quality and controls are never locked. RevLab Pro (one-time purchase, not a subscription, Family Sharing) unlocks nine more engines (V-twin, inline three and five, flat-four, flatplane V8, V10, V12, V16, fighter turbofan) and the front listening position.

■ ALSO English and Korean · iPhone and iPad, portrait and landscape · left- or right-hand drive · metric or imperial · Driver, Engineer and Lab display levels · no account, works offline (leaderboards need a connection).
