We have just hit publish on our 2011 BMW 5 Series article and new, revealing photos of the next 5er showed up on the web. The fellows at Bimmerpost are bringing us new spy shots of a 5 Series test mule spotted in Munich.

As we announced last week, the fist Final Evaluation Phase prototypes are being tested currently, an indication that we might indeed see the new 5 Series, completely unveiled before the year ends.

Sources within the company speak of an official launch at the Geneva Motor Show in March 2010.

While maintaining the class and sporty allure of a 5 Series, the new model will play an important part in the EfficientDynamics strategy. Several features of this technology will be available in the new 5, from brake energy regeneration to specially designed aerodynamics wheels. Every details counts when it comes to fuel efficiency.

Two mild hybrid models are also being considered by BMW with both gasoline and diesel engines.

The new 5er will have an unique design which will differentiates itself from other models within the brand, an indication that BMW wants to stay away from consumers labeling the car as a  “smaller 7 Series”. The car will maintain the typical 50-50 weight distribution and it is rumored to weigh less than the current model.

The interior quality has been upped a notch with many design cues imported from 7 Series and the new 5 GT. It is said to be at the same level with the 5er GT when it comes to quality and design.

Some of you might already wonder what is the exterior paint seen on this 550i, well, we’re here to tell you that we are looking at the Sophisto Grey, the same one available on the new 7 Series.

With the Frankfurt Motor Show just around the corner, expect to see more information being leaked released by BMW.
