From 2009 to 2014, the manufacturer will invest more than €1.9bn (£1.5bn) in new vehicles based on five different platforms.

SsangYong's new diesel hybrid technology, unveiled at the Geneva Motor Show this year, is likely to feature in the new line-up.

The company has said the technology can cut CO2 emissions significantly and improve fuel efficiency by 30 per cent.

Paul Williams, managing director of British distributor Koelliker UK, said: “I have been able to see some of the new models and although I can't reveal any details, I'm very excited about what's coming.

“It's unlikely that all 20 will be appropriate for the UK, but it will mean a wider and more attractive range – there will be different body styles and engines including passenger cars that will enable us to compete strongly in new market sectors.”
