The first design sketches of a new Rolls-Royce that will be launched in 2010 were released today by the luxury car company.

Known as the RR4, the new vehicle will be smaller than the existing Phantom and will be powered by a new engine unique to Rolls-Royce.

The Goodwood facility in Sussex where the BMW-owned company makes Rolls-Royce cars is being completely reconfigured to accommodate the RR4, with extended paint, wood and leather shops as well as a second assembly line.

The company will move to a two-shift system next year as it gears up for full production of the new model.

Chief designer Ian Cameron said, "Effortless performance and standard-setting levels of comfort and efficiency, executed with the utmost care and attention, remain fundamentals of Rolls-Royce design.

"The RR4 has a more informal presence than the Phantom models with a greater emphasis on driving. In design terms this is expressed through its slightly smaller dimensions and more organic form, yet with powerful, purposeful proportions. It is a true and uncompromising Rolls-Royce in every sense."

Rolls-Royce chairman Ian Robertson said: "RR4 will mark a milestone in the history of our cars. The business continues to go from strength to strength and the introduction of this new model will expand the appeal of the brand. We look forward to this next chapter with anticipation and confidence."

Further design and engineering details will be announced next year.
