Speed goes in.
Vroom comes out.

Pick a voice. Give it some revs. Grin a little.

Start with a free spin.

Choose Demo and press Start engine. Hold Accelerate to build speed and Brake to slow down. Or tap Play demo drive and enjoy 35 seconds of revs, shifts and coasting.

Let GPS take over.

While parked, choose GPS and allow location access. Your speed sets the pace, and a virtual six-speed gearbox does the shifting. Comfort keeps things relaxed; Sport holds on to each gear longer.

Find your flavour.

Turn Exhaust character up for more attitude, or down for a softer sound. Vehicle response helps match the revs to your car: Gentle, Normal or Powerful. Start with Normal and see how it feels.

Real-time noise. Real silly options.

These sounds are generated live in your browser, so the note changes as the revs rise and fall. Pick a burbling V8, a smooth V12, a wobbling spaceship or a duck with places to be.

A couple of handy tips.

• Start at a low volume and set things up while parked.
• Keep the page open. Switching apps or locking the screen stops the sound.
• GPS likes a clear signal. If it drops out, the engine settles back to idle.
• Try your speakers with a free voice first; Bluetooth can add a little delay.

Two free voices. A whole garage to explore.

The Grand touring V8 and Quack drive are free. Preview every other voice with the demo, then pick up Full Garage for £3.99 once when purchases open.
