Codenamed F33 and F32, the prototypes caught here continue to wear an effective layer of camouflage that shields some of the styling elements. However, we do know the convertible will sport an electrically-operated retractable hard-top roof.
Engines options will range from 2.0-liter turbocharged engine producing 240 bhp (179 kW / 243 PS) and will also include a twin-turbo 3.0 liter inline six-cylinder engine producing at least 306 PS (225 kW / 302 hp).
Expect to see the 4-Series Coupe unveiled for the first time at the Paris Motor Show in September followed by the Cabriolet in 2013.
