Safety Comparison: Camry vs. Accord - Background

The Honda Accord vs. Toyota Camry rivalry is one of the oldest and most hard-fought rivalries in the automotive industry. 
Safety is one of the most important considerations of midsize sedan buyers, and this comparison compares crash test ratings as well as the presence of airbags, anti-lock brakes, and stability control. Both of these models have had countless hours of safety engineering and numerous safety features put in over the years, but one model has usually nudged ahead of the other on safety in a given year. 

But first, the rating system. The cars were rated out of 100 points. Crashworthiness was given 65 of the points, and vehicle features were given 35. The point distributions were roughly based on the amount of fatalities from certain crash types.

Front crashworthiness is worth 35 points. Three crash tests were used for the analysis: the NHTSA frontal, the IIHS moderate overlap, and the IIHS small overlap. 
The NHTSA full-frontal is worth 7.5 points. Since the 2011-present standards are more stringent, the models tested under both (typically generations introduced before 2011 and retired in 2011 or later) will be scored under their 2011-present scores. Pre-2011 tests can score a maximum of 6 points for each occupant. If the occupant's door is jammed (typically only an issue with older models), one point is subtracted. 
A five-star rating will score close to or at that 7.5 point maximum. Four stars are worth about 6, three stars are worth about 5, two stars are worth about 4 (half of the maximum possible score), and one star is worth 3 or less. For pre-2011 ratings, subtract 1 point from each of the above values. (five stars are worth about 6, four stars about 5, and so on)
The IIHS moderate overlap test is worth 15 points. A good rating will get 12-15 points depending on details (was it "all good" or was there an Acceptable/Marginal sub-rating). Acceptable gets 9-11, marginal 6-8 and poor 5 or less. 
The IIHS small overlap test is worth 6 points. Good is 5-6, acceptable is 4-5, marginal is 2-4, and poor is less than 2 points. 

Side crashworthiness is worth 20 points. The NHTSA side impact, NHTSA side pole impact, and IIHS side impact were used for the analysis. 
For NHTSA side impact, there are a possibility of 8 points, 5 for the driver and 3 for the rear passenger (since rear seats are less frequently occupied). One point per star for the driver, 0.6 per star for the rear passenger. Pre-2011 scores, subtract one full star (e.g. a pre-2011 5 star score = a post-2011 4 star)
NHTSA side pole has a possibility of 4 points - the number of points is one less than the star rating (e.g. a 3-star performance gets 2 points)
The IIHS side impact test is worth 8 points. A good rating is worth 6.5-8 points, acceptable is worth 5-6.4, marginal is 2-4.9. Since a poor rating has a high chance of being unsurvivable, poor ratings get 0 points unless it is a "high-end" poor with no fatal injury measures. These can get up to 1.9 points. 

Rear crashworthiness is worth 4 points. The IIHS rear-impact test is used for this one; 4 points for a GOOD, 3 for an ACCEPTABLE, 2 for a MARGINAL, 1 for a POOR. 

Roof crashworthiness is worth 5 points - 5 for a GOOD, 4 for ACCEPTABLE, 3 for MARGINAL, 2 for POOR. 

Vehicle features looked for are front airbags, side airbags, anti-lock brakes and electronic stability control.
A driver airbag is worth 4 to 7 points, depending on how well-designed it is; a passenger airbag can add 1 to 3 more points. Optional airbags add half of what a standard airbag would.
Side torso airbags are worth 4 points, side curtain airbags are worth 3 to 6 additional points depending on design. 
Anti-lock brakes are worth 2 points optional, 5 points standard.
Electronic stability control is worth 4 points optional, 10 points standard. 

Some assumptions were made, being:

Any vehicle without side and side curtain airbags would be assumed to do POOR on the IIHS side impact and 1 star on the NHTSA side pole crash test. 
Models without a driver airbag would be assumed to do POOR on the IIHS moderate overlap and small overlap.
Models that scored less than GOOD (i.e. ACCEPTABLE, MARGINAL, or POOR) on the IIHS moderate overlap would be assumed to do POOR in the small overlap. 
When results were not available or assumable, best guesses were used. This only applies to older vehicles. 

In cases where some safety features were optional, the range given is the lowest to highest score that a vehicle could earn depending on options. 

The four-door sedan variant was used for each model year.
