As the 2013 E-Class range hits the showrooms, Mercedes is working on the 2014 model year, which is expected to receive some major changes. The E63 AMG performance flagship model has been spied lapping the Nurburgring
in prototype form, and like previous E Class test mules, the dual-unit headlights have been replaced by a single shape design and topped by new LED elements. Heavily disguised bumpers hint at an all-new design. Singling out the test mule as an AMG model are the newly styled quad exhaust tips.
