The future can only be seen in the past, meaning that we can only be wrong or right in retrospect. Today we looked back on the Giugiaro-penned Porsche Tapiro concept, which could be any of the futuristic looking designs of the 1970's. Was it the future? Not quite. Automotive design mostly went another way. That being said, the BMW M1 Homage Concept could be a future grounded in the past. A self-fulfilling future if you will. Either way, most of us enjoyed looking at the future through the eyes of someone in 1970.
