Rotaries, a W16, race hybrids and an electric car. • Two- and four-rotor rotaries and a quad-turbo W16 (Pro) • Three race power units: a 3.0 V10 that revs to 19,000 rpm, a 1.6 V6 turbo hybrid and an endurance V8 hybrid, with race car bodies and a race wheel display (Pro) • A four-motor electric research car: READY start, regen paddles, its own digital cluster (Pro) • Fix: the H-pattern shifter goes into the gear you meant more reliably • Fix: on the drag strip, pressing the brake puts 1st gear in every time • Exhaust pops and crackles on lift-off, real start-tree timing and relay sounds on the drag strip, cleaner sound effects and quieter shift clacks • Less wind hiss at the driver's seat • Battery saver graphics for older devices (the sound stays the same)

Jet engines and drag racing are here. • Three aircraft engines: an airliner turbofan and a nine-cylinder radial (free) and an afterburning fighter turbofan (Pro). The sound, the plume with its shock diamonds, the 3D thrust levers and the aircraft instruments all come from the same physics • Drag strip: quarter mile and 0–100 km/h, Christmas tree, launch control, shift lights and shift grades, your personal-best ghost, the factory driver and Game Center leaderboards • A look of its own for every engine: cover colors and shapes, intakes, header alloys • One tap on START switches the engine off, a drive mode button on the dash, day and night cluster lighting • Re-tuned sound at the driver's seat, in the engine bay and out front • Easier on the battery and cooler: RevLab draws only what changes, lowers the refresh rate when you let go and follows Low Power Mode
