Our spies have snapped some rather interesting photos of what we have always assumed was the BMW 3-Series GT.

[UPDATE] Vehicle was misidentified as 4-Series GT when in fact it's actually a prototype for the 4-Series Gran Coupe variant.

Our spies have snapped some rather interesting photos of what we have always assumed was the BMW 3-Series GT.

The latest pictures reveal the prototype is equipped with the front fascia and taillights from the BMW 4-Series. This leads to speculation that the model will actually be called the 4-Series GT.

Regardless of the name, the model will be offered with a variety of engines sourced from the 3-Series. As such, petrol choices could include a 2.0-liter four-cylinder with 184 PS (135 kW / 181 hp), a 2.0-liter TwinPower Turbo with 245 PS (187 kW / 251 hp) and a twin-turbo 3.0-liter inline-six with 306 PS (225 kW / 302 hp). On the diesel side, there could be a 2.0-liter four-cylinder with outputs of 116 PS (85 kW / 114 hp), 143 PS (105 kW / 141 hp) and 184 PS (135 kW / 182 hp).

The model could be unveiled at the Paris Motor Show, before going on sale in March 2013.
