THE CONCEPT CARS, PART 3
1975 IXSV 2
With many manufacturers presenting experimental safety vehicles in the 70s, IP was no exception. The 1975 IXSV (Ip eXperimental Safety Vehicle) 2 was their second attempt, a follow up to the 1972 IXSV 1.
Being based on the second generation Vagant, the passenger cell had heavy reinforcements and the front and rear crumple zones were lenghtened by a lot. The huge rubber bumper surrounding the grille not only was effective in protecting the bodywork in low speed accidents, it was also said to be much more pedrestrian friendy than a regular car front would have been.
An interesting take was also the rubber blocks on the doors. Supported by heavy steel reinforcements in the doors, they was said to have three functions. Very small impacts, like the door of another car being slammed into the door at a parking lot, was absorbed by the rubber. Inside, they featured a crushable honeycomb structure absorbing energy in a crash. In minor accidents, the idea was that the blocks should crumple, saving the door with just a new block needing to be bolted in place, which would have lowered insurance costs. At higher speed impacts, the strenghtened doors and bodywork would of course have to cope with the impact, but the crumpling of the blocks still would have lessened the energy transferred to the cars safety cell.
The front seatbelts was attached to the seats themselves, to ensure that they always was in the correct position. If the seatbelt was not fastened, the automatic transmission could only be used in low or reverse, a system that would not have been to inconvenient when it came to moving the car shorter distances but still would have made it hard to drive without a seatbelt. The rear headrests could be folded down flush with the seatback to improve rear vision, but as soon as there was a passenger in that seat, the headrest popped up in place. Other technical gizmos included front airbags, a backup camera and daytime running lights.
Maybe seen as something from a totally bygone era today, the ESVs of the 70s still was an important experiment that made features we take for granted today see the light of day. Other features are forgotten and might as well be so for all the future.
