Aston Martin has secured £200 million in funding to develop new luxury models including the DBX which it says "will drive the future of the company".

The investment comes in the form of £200 million of preference shares - £100 million of which were issued yesterday with the remaining £100 million, which have been subscribed for, to be issued over the coming year.

It is being led by major shareholders Investindustrial and Tejara Capital.

The news follows swiftly on from rumours it is looking for a new manufacturing site where it could build 4x4s with Longbridge hotly tipped as one of the frontrunners.

The Gaydon-based manufacturer said in a statement: "This major investment in new luxury models is at the core of Aston Martin's strategic vision.

"Under the plan, the company will expand into the luxury GT crossover market with the introduction of a new vehicle based on the DBX concept shown at the recent Geneva and Shanghai motor shows.

"With the addition of new model lines, the company's strategy will help drive future growth, always ensuring that Aston Martin builds the world's most beautiful cars that deliver true sporting ability with passion and refined luxury."

Chief executive Andy Palmer added: "This additional long-term funding will enable us to add extra model lines and broaden our presence in the luxury market segment by the end of the decade.

"The DBX concept has generated interest far beyond our expectations. The additional investment will allow us to realise the DBX and other new luxury vehicles that will form the strongest and most diverse portfolio in our history."

Separately, Aston Martin has today announced full-year revenue for 2014 of £468 million, down from £519 million in 2013, and adjusted EBITDA of £66 million, also down from £84.4 million.

It said it had simultaneously increased its product development spend by 45 per cent and in 2015 expected global demand to remain high while it developed and expanded its current range.

This would start with first customer deliveries of the limited edition, track-only Aston Martin Vulcan and the race-inspired Vantage GT12, the statement added.

Jonathan Browning, chairman of the Coventry and Warwickshire Local Enterprise Partnership welcome today's announcement.

He said: "This is good news for Aston Martin, its workforce, and for the whole of Coventry and Warwickshire.

"The company is a world-famous, much-admired brand and it is encouraging to see it developing in what is a tough and competitive market. Their plans, supported by their investors, suggest exciting years ahead for the company and its suppliers."
