How was Vanko not crippled by being crushed repeatedly between a Bently and a wall?

In the introduction of Anton Vanko in Iron Man 2, he stands ready to strike the helpless Tony Stark, who is saved by the timely arrival of Pepper Pots and Happy in a Bently. They crush Vanko against a nearby wall several times but he emerges unscathed. How? He is wearing no armor. He is not super-powered in any way revealed in the film. Why isn't he a cripple after this scene?
