The updated test is similar to the original evaluation but uses a heavier barrier traveling at a higher speed to simulate the striking vehicle. The new barrier weighs 4,200 pounds — close to the weight of today’s midsize SUVs — and strikes the test vehicle at 37 mph, compared with a 3,300-pound barrier traveling at 31 mph in the original evaluation.
For now, a good rating in the original test is enough to qualify for either of the Institute’s awards. However, starting in 2023, a good or acceptable rating in the updated test will be required for the lower-tier TOP SAFETY PICK award, and a good rating will be needed for the higher-tier TOP SAFETY PICK+.
The Mustang Mach-E earns good ratings for head protection for both the driver and rear passenger. Measurements taken from the dummies show a low risk of injury to most body regions. Only the driver’s torso registered a somewhat elevated risk of injury.
For structural performance, the SUV was downgraded from good to acceptable because the left rear door partially opened during the crash. This did not have a significant effect on the movement of the dummy or how much the passenger compartment was crushed by the impact. However, a door that opens in a crash could allow an occupant, especially an unbelted one, to be partially or completely ejected.
