Lots of auto safety information is easily available, though many people never
see it. Both crash test scores and safety features are important. While there
are an increasing number of safe, fun-to-drive vehicles, many vehicles are
much less safe than seemingly similar alternatives. Several important new
safety features are currently trickling down from luxury vehicles to more
mainstream models (just as anti-lock brakes and front airbags have already).
The most important are stability control and side airbags (for both the torso
and head). These features save lives. For justifications of the importance of
these safety features, see the older links at the bottom of this page and the
many excellent publications of the Insurance Institute for Highway Safety
(IIHS).
These web pages focus on safe, fun-to-drive vehicles. The most up-to-date information concentrates on (entry-level luxury) sport sedans:
I believe this is the most thorough quantitative comparison of the safety and performance of vehicles in this class available anywhere.
