That is sadly the case for all brands (merc and audi are the worst).
There was a feature on the revised A4 range in Autocar a few weeks ago. They interviewed Audi Exterior designer Amor Vaya. He evidently tried to persuiade us all that their design team have taken note of criticism of all models looking the same but their interpretation od a different look is giving each model a slightly different grille design 
Q&A with Amor Vaya, Audi exterior designer
What did you focus on with the redesign?
“The A4 is a well-proportioned car, but the old one was occasionally called a little boring. We’ve put a lot of life and energy into it. We didn’t want to change the design principles, but we wanted to make a statement.”
How did you do that?
“The design is now a lot richer, more expressive. We’ve focused on the detail, with the use of 3D design elements, chrome parts and other small things that can make a big difference.”
What are the challenges of doing a facelift design?
“The fixed points were all designated six or seven years ago, so we have to work around that. That gives some limitations, but we’ve evolved the A4’s design substantially.”
Why focus on differentiating the S4 and Allroad quattro?
“We wanted to give each variant its own character. We’ve been criticised before for making every model and variant look similar, so now each model has its own character, and every car inside that model family does, too.”
