Ahead of the vehicle's public debut at the 2013 Geneva Motor Show, motorists have learnt that the car is a more practical hatchback version of the standard BMW 3 Series model.
On top of this, the 3 Series Gran Turismo is being styled around a similar mould to that already seen on the 5 Series Gran Turismo vehicle.
To further illustrate how this addition to the 3 Series range differs from its predecessors, the Gran Turismo is 200mm longer than a 3 Series Touring car, 81mm taller and complete with a 110mm longer wheelbase.
All of this extra space helps the interior of the vehicle to boast 520 litres of luggage capacity with the rear seats in position – close to 25 litres more than the 3 Series Touring model offered drivers.
There are a few aspects of the 3 Series Gran Turismo which fans of the range will recognise, however, such as the fact that the car's cabin is styled with a similar dashboard layout to that of the Saloon, Touring and Coupe vehicles.
BMW's more familiar touches continue to shine through when drivers begin to notice that the Gran Turismo model includes the German manufacturer's iDrive infotainment controller system and the firm's state-of-the-art head-up display.
Step back out of the BMW 3 Series Gran Turismo vehicle though and the changes between this new car and other motors in the range appear once more.
For starters, the Gran Turismo has a sportier stance than its siblings, helped along by the chassis' sharp nose design and a multitude of sharp curves.
Reach at least 68mph in the 3 Series Gran Turismo and the car's party trick comes into play – the pop up of an integrated spoiler.
According to BMW, this spoiler reduces lift on the vehicle's rear axle by more than 35 per cent and thus enables the motor to retain the same aerodynamic qualities as that of the 3 Series Saloon.
More can be seen of the new BMW 3 Series Gran Turismo at the 2013 Geneva Motor Show next month, ahead of its UK launch in the summer.
