Ford is introducing a gear-shift indicator system to help boost fuel economy in its vehicles.

The new dashboard-mounted device will be fitted to ECOnetic versions of the Fiesta, Focus and Mondeo, as well as on the Transit and Transit Connect vans.

The indicator senses the way a vehicle is being driven and identifies the most suitable gearchange point to maximise fuel efficiency.

Tim Winstanley, Ford’s diesel powertrain manager, said: “Many drivers could improve their fuel economy significantly by changing gear earlier.

"The indicator provides drivers with a helpful aid to using less fuel and encourages a smoother driving style.”
