What's the point in changing the logo ? From my point of view it's better to stick with the original, as it is more authentic (particularly on a car Make that has such a long and distinct history as lancia...)
I'm split two ways over this. The original pennant/lance was certainly authentic,and historical.However, the modified version looks smoother,probably marrying, blending better, with the new model shapes.Need to see it in the flesh,so to speak. On balance though,I like the new design, so yes I think appropriate for the new sleek models.
Think the Alfa's is fascinatingly artistic,as well as historical, encompassed symmetrically in a circle. Always thought the Lancia design was a bit irregular,the lance/pennant seemed 'sticky outie' from the shield shape. They are all fine, where appropriate.
