14. Volvo 140 Series (1966)
The Volvo 140 Series, introduced in 1966, emphasized passive safety with its robust safety cage, crumple zones, and a collapsible steering column. Its restrained, boxy design reflected Scandinavian design principles, focusing on functionality and simplicity. This approach influenced automotive design by prioritizing both form and function, setting a precedent for vehicles that balanced aesthetic appeal with occupant protection. (Volvo Heritage)
