There was a discussion in Rennteam recently of the Cayenne's weight and it's relationship to occupant safety. In the US at least there is the general public perception that a larger, heavier vehicle is safer.

The NHTSA completed a study yesterday that tends to confirm this traditional wisdom:

NHTSA Study Finds More Weight Can Equal Safer Vehicles

Federal regulators Tuesday said a new study shows reducing the weight of vehicles, done mostly to improve fuel economy, has resulted in more traffic deaths, especially among small-car owners. The study shows that until tougher standards are set for automakers to design trucks and SUVs to inflict less damage on other vehicles in crashes by way of vehicle height standards and bumper designs, occupants of heavier SUVs and trucks that get poor fuel economy will be safer than occupants of lighter vehicles.
