GERMANY'S most popular diesel engine has been lined up to power a fresh bid for fleet sales by Seat.

The Volkswagen Group's Spanish subsidiary is set to boost its range of Leon hatchback and Toledo saloon models with the addition of flagship 130bhp turbodiesel versions, it was revealed at the Barcelona Motor Show.

Used extensively by other VW brands, the 130 unit is specified in more than 20% of VW Golf GT sales and will broaden the appeal of Seat cars in the lower and upper medium sectors, believes product manager Will Currie.

Available from August, it is expected to give the new S and SE trim versions the ability to reach 62mph in less than 10 seconds, a 130mph top speed and CO2 emissions of between 140g/km and 150g/km.

Currie said: 'We have high hopes with these cars and expect the Leon to be successful with business buyers. Pricing is being negotiated, but we are aiming to offer high performance for a relatively low premium.

'The Leon accounted for one- third of our total of 30,000 registrations last year, and we're confident the new engine will prove effective against the competition from Citroen and Peugeot, who have had a lot of success with diesel power. Our aim is for the car to win 4,000 fleet sales this year.'
