Figure 5-7: Approach to the definition of the vehicle segments typical mapping.

The 60 areas EuroNCAP gives a rating for each vehicle have been account and grouped for the different vehicle segments. A frequency analysis has been performed on each of these areas to define an average mapping for each vehicle segment. To build these mapping the distribution of red, yellow and green scores for every area has been computed and, based on them the average mapping have been built with the following criteria in each impact test area:

o If a colour rate represents more than a 50% in an impacting zone, the area is coloured in such colour.

o If there is not any colour rated with more than a 50%, yellow colour is applied.

It can be seen in the Figure 5-8 the distribution of red, yellow and green ratings over the bumper and the bonnet leading edge areas. In both cases, the sample size is 414 tests (6 zones x 69 vehicles).

Figure 5-8: Legform and upper legform testing area ratings for the different car segments.

Regarding the former, it can be seen that red percentages are rather constant for SMC, MPV and SUVs with values over the 70-80% in all the areas. On the other hand, SFC and LFC show more dependency on the impact area.

For SFC, green reaches 40% in the middle of the bumper and around 25% in the sides while in LFC, red percentage decrease especially in the middle of the bumper (65%) while it is maintained in 80% for the sides. In the non red part, green is the dominant colour in SFC and yellow in LFC.

Regarding upper legform tests, current SUV and MPV are almost always rated red while the trend is rather different for the other segments.

LFC and SFC show similar trends for red percentages; in both it is maintained around a constant value for all the areas (70% for LFC and 50-60% for SFC), while the green and yellow diagrams show some differences. In SFC green is maintained close to 20% in all areas while it shows this behaviour only in the middle part for LFC.

Regarding the SMC, they show differentiated trends in the middle, where green and yellow accounts for the 60%, and the sides, where red is again the predominant colour.

It can be seen in Figure 5-9 the distribution of red, yellow and green rates over the child test area, which covers the bonnet area between WAD 1000 and WAD 2100 and includes around 1600 ratings.

Figure 5-9: Child headform testing area ratings for the different car segments.

It can be observed a similar trend in the child impact zone corners for all the segments and different distributions in the middle part depending on the vehicle segment.

It can be seen that the SUV middle child impact area remains commonly red rated while this is not the case for the rest.

SFC and LFC red parts are reduced to a constant value less than 10% for the former and 20% to the latter reaching the green percentage constant values near 60% and 45%

respectively in the C3 and C4 areas. Moreover, it is also relevant that for areas C2 and C5 green predominates for SFC and yellow predominates for the LFC.

For the case of SMC, similar tendencies to SFC and LFC are found in C3CD and C4CD but due to the shorter bonnet C3AB and C4AB tests are performed close to the rear part of the bonnet and the results are not so positive. In these parts, red percentage increases near 40% and yellow is more predominant in the non-red part.

Finally, MPV show an intermediate behaviour between the SUVs and the family cars with moderate importance of green and yellow in the middle (together hardly represents the 60%) which is rather maintained also to C2 and C5 with the exception of the C4B where red shows a sudden peak.

Figure 5-10 shows the mapping of the adult headform impact zone of the different segments including the green rate given to windscreen impact and the red rate given to A-pillar impact (both without testing).

Red scores due to A-pillar impact in A1A and A6B were given to all cars, but the green score for middle windscreen impact (commonly A2AB, A3AB, A4AB and A5AB) are only extensively given to SMC, SFC and MPV groups. In these three groups, C and D part, show some variations although commonly red rates are again over the 50%.

In the case of LFC most of adult tests impacted on the windscreen base and not in the windscreen middle, therefore the red rating is maintained over 60% but in the A3C and A3D, where yellow is more predominant.

Finally SUVs show a different trend as they present a rather constant behaviour in A3 and A4 zones with red percentages around 50% and a bit higher, but also rather constant in the A2 and A5 zones, near 70%.
