Japanese car nuts build racecars powered by shouting 'Brrrm! Brrrrrm!'

Vid A team of Japanese car enthusiasts, backed by Nissan, have created a toy racetrack where cars speed along dependent on the driver's ability to imitate a V6 in full throttle.

The "Voice Driver Cup" is a PR stunt promoting Nissan's new sports model, the Fair Lady 370Z, but involves Japanese developers making car noises into microphones in the hope of spinning their vehicles around the track faster than those of their compatriots.

We’re grateful to Tech In Asia for the translation, which tells us there will be a smartphone app out soon - for those who want to make the noises but don't have the space for a physical race track.

Control is limited to speed and the track is partitioned to guide the remotely controlled cars around, which is disappointing as we'd like to see players imitating the screech of breaks to slow down, and tyres torn by cornering, but perhaps that will come with version two. ®
