Ford has reached a new agreement to add Transit all-wheel-drive models to the National Grid's fleet of over 3,000 Ford vehicles.

The deal confirms the continued supply of Ford commercial vehicles to the gas and electricity business over the next three years.

National Grid’s renewed agreement with Ford follows a tendering process that included all European manufacturers covering the utility’s area.

The National Grid vehicles, which are purchased outright, are expected to cover up to 18,000 miles a year.
