The reason modern cars are usually heavier then old cars is because they are safer -- for example, larger crumple zones, ABS, VSC, HSC, airbags, better windshields, safety cells, anti-intrusion bars, other barriers.
Are you less likely to survive an accident in a modern car? Yes, you are. Depending on who you ask airbags by themselves save 5,000-20,000 people per year.
