Ford's latest prototypes for the new Mustang Shelby GT500 are wearing the least camouflage gear yet. Clearly visible are the car's new aero elements, massive brake discs, and Cobra badge.

Another Ford making the spy shots round is the sporty ST variant of the recently revealed fourth-generation Focus. The new ST is expected to feature a smaller engine but more power.

Mercedes-Maybach will use the upcoming Beijing auto show to present an SUV concept that incorporates the luxury of one of the marque's high-end sedans. It's thought the concept will preview a planned Maybach version of the next-generation Mercedes-Benz GLS.
