The 2017 BMW 5-Series GT has been spied for the first time.

Set to retain its title as the most controversial member of the 5-Series lineup, the second-generation GT has a prominent kidney grille and slender headlights.  Moving further back, we can see new mirrors, a sloping roof and an upward sweeping beltline.  The model also has a dual exhaust system and a heavily camouflaged rear hatch.

The design looks rather promising this time around and it shouldn't come as much of a surprise as the lukewarm reaction to the original Gran Turismo pushed designers to make the second-generation model sportier and more attractive.

Engine options remain unconfirmed but the model is expected to be offered with a variety of different petrol and diesel units.  Choices are expected to include a 3.0-liter six-cylinder with 326 PS (240 kW) and a 4.4-liter V8 with 449 PS (330 kW) and 650 Nm (479 lb-ft) of torque.  There should be a 3.0-liter six-cylinder diesel engine that develops 265 PS (195 kW) and 620 Nm (457 lb-ft) of torque.

Regardless of what is under the hood, the next 5-Series GT should be significantly lighter than its predecessor as it will ride on the same platform that underpins the new 7-Series.  This, combined with other weight saving measures, could enable the model to weigh about 100 kg (220 lbs) less than its predecessor.
