Seat has won its biggest fleet deal after it won the contract to supply 500 new Leon Ecomotives to British Gas.

The deal was brokered by Seat UK’s newly-revamped Fleet and Business Sales team led by the head of fleet and business sales Nick Andrews.

The eco Leon come top in a tender process that initially involved more than 50 models.

The first cars, which emit 99g/km of CO2, are due to be delivered early in 2010.

The cars feature Auto Start/Stop and energy recovery functions, allied to the engineering advances provided by a new 1.6-litre common rail diesel engine.

In addition, the new car is fitted with SEAT’s recommended gear indicator, which displays the most appropriate gear for the driving conditions.

Colin Marriott, fleet manager at British Gas, said: "Seat has taken an industry-leading approach; innovative, flexible and way ahead of anyone else involved in the tender process.

"This is a fantastic addition to our fleet and the additional advanced engineering features help us to continue to lead the way on reducing emissions."

Nick Andrews, added: "Sally Livingstone, my new national fleet sales manager and the rest of the team have secured an outstanding result with this successful tender.

"But this is just the beginning: our aim is to make Seat a fleet manufacturer of choice and we will be working hard to achieve that ambitious target over the months and years ahead."
