The Crown Victoria came under criticism years ago after crashes in which some police cars burst into flames following rear-end collisions. That's a particular danger for police cars which are commonly stopped right alongside high-speed highways.
Ford responded by beefing up the Crown Vic's rear crash protection and adding a fire suppression system. Today, Ford boasts that the Crown Vic is the only police car to pass 75 mile per hour rear-end crash testing.
The new Police Interceptor is, likewise, engineered to protect against high-speed rear hits. It's designed to protect against more than just crashes, though. The front seatbacks have anti-stab inserts to protect against attacks from back-seat occupants
