Modern cars are made crumple though, remember that! Nothing crumpling on that mini to absorb the energy of the impact, so much much more of it going into/through the passengers... lucky to live through that one, nasty crash!

The mini does have crumple zones, obviously not as effective as modern cars, but they do absorb a bit of energy. The whole front subframe is designed to crumple and protect the passengers. The rest of the car like the floors and pillars also take a fair bit of distortion.
But with that V-tec mini it would be interesting to repeat that crash with a standard mini and see what the outcome is. The fact that the V-tec mini will have a custom subframe would most likely mean its not going to absorb as much energy as the original, not to mention the flip front.
