There's no point in making the same old models year after year.
Literal
Every-year same old-model's products [object-を] make-[concessive-ても] don't-begin.
~ても始まらない ('even if you X, it won't start/get you anywhere') is an idiomatic expression meaning 'there's no point in X,' 'X is futile.' 始まる here is used metaphorically — 'it doesn't get started,' meaning 'nothing comes of it.' 旧型 ('old model') contrasts with 新型 ('new model').
