I love Peugeots, had one for 5 or 6 years. But lately I think Peugeot is loosing the plot on the design of its cars. Let's clarify what's wrong: detailing. Namely the identity of the front design. It's wrong in the current 407, passable in the 308, and completely wrong in the Peugeot 408 preview below and the 3008 that follows. By the way, the 408 image is from Autojournal and it's credible and it signals that the final design might be frozen by now.
There are also a couple of things wrong in the technical department: the huge front overhang in most recent Peugeots, and the lack of multilink in the Peugeot 308 range: remember when the 306 was clearly superior to the Golf III in handling?... Oh, and about that 3008 Prologue thing below, is that some sort of SUV-thing?... cuz Peugeot lacks AWD in that range of cars. Just don't try pulling a FWD-SUV, ok?
There are many things done right in recent Peugeots too: interior design and perceived quality, diesels, diesels, diesel engines, diesel engine technology...
So not everything is wrong, the overall design proportions are ok, the detailing and front end is really the worst part... but it's a very important one. But I can help you. For free, just cuz I like you people and the cars you made for so many years. Don't be afraid of sending an email, I won't share your secrets in the blog since I respect your work and the work from other manufacturers. I can help you make it work in the future.
