With a fresh nose and redesigned flanks to bring the it more into line with the looks of the smarter 3 Series GT, the new 5 Gran Turismo will join the revised 5 Series Saloon and Touring as one of six new BMWs debuting at Frankfurt Motor Show in September.
These spy shots show that there’s a new lower front bumper section with redesigned air intakes. The front grille and headlamps appear untouched, but there are more significant changes at the back of the car.
The hatch’s integrated spoiler will be replaced with a softer, more understated bootlid, complemented by a new rear bumper design. It won’t alter the 5 Series GT’s 1,650 litres of boot space, however.
Interior changes are likely to be limited to colour choice and spec adjustments, while the current engine line-up will remain.
This means that the range will start with a 2.0-litre diesel, which delivers 53.3mpg and 139g/km, through to the 449bhp 4.4-litre V8 in the 550i SE which has a 0-62mph time of 5.0 seconds.
As with the revised Saloon, the GT will have a new iDrive Touch interface, where a touchpad allows drivers to write with their fingers to enter sat-nav destinations and a smartphone-like pinch-to-zoom facility.
The revised BMW 5 Series GT will go on sale in the UK in late 2013, with prices starting from £36,500.
Lining up alongside the trio of updated 5 Series at the Frankfurt motorshow 2013 will be the production version of the 4 Series Coupe, as well as the all-new, more luxurious X5 SUV. But while we'll see pictures of these cars ahead of the event, the eagerly awaited production version of the i8 hybrid supercar will be kept secret until it stars on the stands.
