Rolls-Royce denied automotive industry rumours that its planning a move downmarket with a cheaper car.
The BMW-owned super-luxury brand currently produces only one car, the £200,000-plus Phantom, which it builds at a new factory near Goodwood in Sussex.
Sales rose by about one per cent to 796 last year, and with the likes of Maserati planning a less expensive model aimed at boosting sales, there has been speculation that Rolls-Royce would take the same route in a bid to take sales away from slightly less expensive rival Bentley.
But BMW chief executive Helmut Panke dismissed the idea - at least for now.
Speaking at the Detroit Motor Show, he said: "The strategy right now is to reposition Rolls-Royce as a brand and not move down from that pinnacle, icon position too early.
"We confirm that we will also expand the Rolls-Royce brand product portfolio, but not now."
Rolls will launch a stretch Phantom in the US and plans to make a convertible in 2007.
Deliveries of Bentley cars grew more than 30 per cent to a record 8,627 last year.
Growth was strongest in the US where the Continental Flying Spur, which is on display at Detroit, costs £94,000.
Sales of cars and trucks in the US will fall "modestly" this year but intense competition in the market will put pressure on prices, economists from Detroit's traditional Big Three carmakers said.
The chief economists for General Motors, Ford and Chrysler projected between 16.7 million and 16.8 million light vehicles will be sold this year.
About 16.9 million vehicles were sold in 2005.
