Infiniti will introduce the world’s first hybrid vehicle with an audible pedestrian warning system as standard.

The system, fitted to the company’s forthcoming M35h model, features a variable pitch and volume tone synthesiser, which is computer-controlled and works automatically from 0-19 mph.

The warning sound that was chosen is a 'sine-wave', audible to all age groups and producing minimal amount of noise pollution, the company claims.

The sound sweeps from high to low frequency depending on vehicle speed and depending on whether the M35h is accelerating or decelerating.

Mated to a 3.5-litre V6 petrol engine with 302bhp is the hybrid’s 67bhp electric motor. The sprint from 0-60mph takes 5.9 seconds with a fuel economy figure of 39mpg the company claims.

The M35h should be in UK showrooms by May.

Currently it is illegal in the UK for a motor vehicle to be fitted with a variable pitch tone horn except for the emergency services. Surely this would also apply to this Infinity?

Re: Infinti creates noisy hybrid

I think that the obvious synthesised sound would be of an emergency vehicle, which would clear cars out of your way.
