Rolls-Royce seems to be out testing its new smallest car in the state most likely to buy it, California. But the RR4 wasn't making its way trough Hollywood, instead it was out for testing in the Sierra Nevada Mountains area.

Although not much of the car can be seen, it doesn't appear to be highlighting the suicide doors that were seen on other test mules. This may signal a design change to the car, or just simply a disguise over the rear-hinged rear doors. Either way, the full truth should be known when the car makes its debut in March at the Geneva Motor Show.

The RR4 should be powered by a modified version of the V8 twin-turbo from the BMW X6. A diesel option will join the RR4 lineup in the future, but may not make it to the U.S. Like the newly launched 7-Series it will feature latest generation of the iDrive technology that controls navigation, communication and audio systems.
