Japanese car giant Nissan has announced all new models will be fitted with a fuel efficiency gauge in bid to make motorists drive ‘greener’.
The gauge will give drivers more information on how their driving style directly relates to fuel economy.
It allows the driver to view both instant fuel-efficiency and average efficiency readings.
For example, by accelerating, the driver would instantly see an increase in fuel consumption reflected on the gauge.
Nissan says trials have shown the gauge helps drivers ‘improve their eco-driving habits’.
It said the gauge led to motorists accelerating and braking more smoothly, which potentially could lead to a 10 per cent improvement in fuel-efficiency.
Which? motoring editor Richard Headland said: ‘Fuel efficiency gauges are not new – indeed, many cars already have them in some form.
‘However, at-a-glance gauges can be easier to read, which should help drivers assess the impact of putting their foot down.’
