Starting with the exterior, besides fitting the Kelleners 2011 BMW 5 Series with massive 20 inch alloys (Hamburg and Berlin designs), the tuner has also added a discrete aerodynamic package comprising from a redesigned spoiler lip, a rear spoiler and rear apron with integrated diffuser.
Various other elements like an electropolished stainless steel mesh for the lower front grille have been added as well, plus the Kelleners 2011 BMW 5 Series received two enormous oval stainless steel exhaust pipes, measuring 225 x 90 mm and a 30 mm lowered suspension for improved handling.
In terms of performance, the Kelleners 2011 BMW 5 Series manages to develop around 20 percent more power comparing to the stock version, and to give a few examples the 520d develops 218 HP (160 kW) and 450 Nm of torque instead of 184 HP (135 kW) and 380 Nm, while the 535i jumps from 306 HP (225 kW) and 400 Nm to 367 HP (270 kW) and 480 Nm of torque.

Kelleners press release :
World premiere in Geneva: Complete Tuning Package for the BMW 5 Series with M Sports Package
    * Enhanced performance for petrol and diesel engines
    * Comprehensive aerodynamics package creates a sporty appearance
    * 20-inch alloy wheels in "Hamburg" and "Berlin" designs
    * Interior enhanced with added accessories
Kelleners Sport brings new dynamics to the BMW 5 series with M sports package. The comprehensive aerodynamics package, enhanced performance, optimised suspension and stylish upgrade of the interior transform the already sporty-looking saloon into a really racy vehicle.
Kelleners Sport engineers have unleashed around 20 per cent more engine power for petrol and diesel models. The 520d, for instance, now reaches 218 hp (160 kW), instead of the standard 184 hp (135kW), and maximum torque reaches 450 instead of 380 Newton metres. The performance of the 535i jumps from 306 hp (225 kW) to 367 hp (270 kW) with maximum torque increasing from 400 to 480 Newton metres.
The 5 series with M sports package demonstrates this increase in power
together with Kellener Sport’s elegant aerodynamics package. The
electropolished stainless steel mesh of the MS three-part front grille
emphasises the sporty origins of the BMW specialists. The dynamic
design starts at the MS front spoiler lip, moves onto the side
mouldings and grabs attention at the end with the rear spoiler,
Kelleners lettering and MS rear apron with integrated diffuser. The
oval stainless steel exhaust pipes measuring 225 x 90 millimetres add a
sporty edge both left and right.
The sport springs set from Kelleners Sport is instrumental in the
improved handling of corners. This lowers the vehicle by around 30
millimetres, therefore reducing roll and pitch movements.
Kelleners Sport alloy wheels are also an important element of the new
release. With dimensions of 9×20 inch at the front and 10×20 inch at
the rear, they are fitted with high quality tyres in sizes 255/35 and
285/30. The BMW expert offers the "Hamburg" design in polished silver
graphite, polished platinum silver and matt black. The "Berlin" alloy
wheel is available in polished platinum silver, polished matt black and
matt black.
Specially selected features also enhance the interior of the car. These
include pedals and footrests made of polished aluminium as well as a
set of real velour black floor mats carrying the tuner’s logo at the
front. The high quality interior trim made of midnight black leather
with white stitching adds to the feeling of elegance.
With this comprehensive package, Kelleners Sport enhances both the
dynamics and the individuality of the BMW 5 series with M sports
package.
