Based on the next-generation 5 Series, the new GT model - or Progressive Activity Sedan (PAS) as BMW like to call it - will compliment the existing sedan and touring variants in the range.
Like all of the four-door coupes which are set to hit the market, luxury rather than practicality is key, with the 5 Series PAS boasting only four individual sports seats.
In order to accomodate its passengers in comfort, the concept is larger than the standard 5 Series in all dimensions - measuring nearly 5 metres long, 1.9 metres wide, 1.56 metres high and using a limo-like wheelbase of just over 3.0 metres.
Any feeling of claustrophobia for rear seat passengers has been eliminated by including pillarless doors and a panorama glass roof, reportedly offering the same legroom as the 7 Series and the headroom of the X5 SUV.
Luggage capacity can increase from 430-litres to 570-litres as the rear seats move forward by up to 10 centimertres while still offering the same legroom as a standard 5-series, or can be folded away altogether for 1650 litres of space.
Boot access is imrpoved by using a two-piece tailgate system similar to the design found in the Skoda Superb.
While no mechanical details have yet been released, the new 5 Series PAS will make its official debut at the Geneva motor show with a production model slated to appear at this year's Frankfurt motor show.
