You can call it atrocious or whatever other extreme word you want to use... if you're going based on LETTER GRADES. I like to read the fine print and see exactly what happened to the dummy during the impact.
BOTH the E Class and 5 Class allow for possible lower leg injury per IIHS 2014 model years.
Only the E Class allowed for head impact to the A-pillar because of too much play in the seatbelt.
Per IIHS on Mercedes E-Class
"The dummy’s head mostly remained in contact with the frontal airbag,
but the head still hit the A-pillar because the seat belt allowed excessive forward excursion of the dummy's head and torso."
Per IIHS BMW 5-Class
"The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects."
E-Class Head Injury Criterion score 245
5-Class Head Injury Criterion score 86
The smaller the number the lesser risk of injury.
E-Class Chest maximum compression 45mm
5-Class Chest maximum compression 32mm
The more the chest compresses the higher the risk of broken ribs, punctured lungs, damage to heart and surrounding vessels.
Hip, Upper Leg and knee injuries... the scores are basically the same on both cars.
Finally when you get to the lower leg and foot.. the E-Class definitely did better. I'm definitely not thrilled about what happened there in the lower leg area.
Is there a recall on that seatbelt in the E-Class?
And yes I'm giving you a hard time on this because you claim that the driver would get crushed and not survive an accident in a 5-Class... yet the information from IIHS shows quite the opposite. I rather break my foot or lower leg than have my chest compressed another 15mm or my head hit the A-pillar.
