The Sauber Petronas Alarm Clock. Otherwise known as ‘spot the clock’. Well I can’t see it, can you? And the product description helps not a jot. £19.95.
By pressing the start button the original ignition and tick over sequences are activated. Continual pressing of the accelerator triggers the acoustic experience of acceleration until the car has reached “top speed” or maximum revs per minute. The engine maintains this rpm status and the corresponding pitch until the accelerator is no longer activated.
