Many factors weigh in to determine Forbes’ list of Safest Cars for 2011. First, all cars had to be chosen as a 2011 “Top Safety Pick” by the Insurance Institute of Highway Safety. Second, in order to create a list exclusively made up of cars, all trucks, vans, SUVs, and crossovers were removed. Then, any models that did not receive a perfect score of “good” on every IIHS crash test were removed.
The four crash tests include; front-, side-, and rear-crash tests as well as a rollover test. The front test includes a 40-mph frontal offset crash that measures how well the car’s restraint system controlled the dummy’s movement during the crash. The side tests are based on crashes where the side of the vehicle is hit by an object moving at 31 mph. The rear-crash test measures the dummy’s neck pressure when they are hit from behind by an object moving at 20 mph. The rollover test, tests the strength of the roof when a metal plate is pushed against the roof at a rate of 0.2 inches per second. To get a “good” rating on the rollover test, the roof must withstand a force four times greater than the vehicles weight before reaching five inches of crush.
After all the tests had been completed and the numbers were calculated, Forbes’ named these vehicles as the safest cars in 2011:
• BMW 5-Series
• Buick LaCrosse
• Cadillac CTS Sedan
• Chevrolet Cruze
• Lincoln MKS
• Mercedes C-Class
• Mercedes E-Class Sedan
• Subaru Legacy
• Subaru Outback
