EUROPEAN NEW CAR ASSESSMENT PROGRAMME (Euro NCAP)HEAVY QUADRICYCLES/L7 - ASSESSMENT PROTOCOL – OVERALL RATING

1INTRODUCTION

Euro NCAP first tested L7 type vehicles in 2014. Individual documents are released for the twomain areas of assessment:••Test & Assessment Protocol Frontal Impact – Adult Occupant Protection;
Test & Assessment Protocol Side Impact – Adult Occupant Protection;

In addition to these two assessment protocols, the present document is provided describing themethod and criteria by which the overall safety rating is calculated on the basis of the vehicle
performance in each of the above areas of assessment.

OVERALL RATING CALCULATION

2.1

MethodThe overall rating is composed of scores achieved in the two areas of assessment:
Adult Occupant Frontal Impact & Adult Occupant Side Impact

Body regions assessed in Frontal Impact (Driver only):
HeadNeck
Chest
Knee & Femur

4 points
4 points
4 points
4 points

Body regions assessed in Side Impact (Driver only):
Head
Chest
AbdomenPelvis4 points
4 points
4 points
4 points

The protection provided for adults for each body region are presented visually, using coloured
segments within body outlines. The colour used is based on the points awarded for that bodyregion (rounded to three decimal places), as follows:
Green
Yellow
OrangeBrown
Red‘Good’‘Adequate’‘Marginal’‘Weak’‘Poor’

4.000 points
2.670 - 3.999 points
1.330 - 2.669 points
0.001 - 1.329 points
0.000 points

For dummy results above or below the lower and higher performance limits, 0 to 4 points isavailable. For dummy results falling between these two limits a score of 2 points is automaticallyawarded (i.e. sliding scales not used for L7 vehicles). However modifiers such as dimensional
based modifiers, inspection modifiers, T12 and Backplate are then applied to the 0, 2 or 4 point
body region result.

The weighted overall score is calculated from the individual assessment scores using weightfactors. These weight factors reflect the relative importance of the frontal and side impact
performance. The weight factors shown below are used in an effort to relate to real world
accidents resulting in AIS3+ injuries. The frequency of this injury severity occurs up to 3 times
more often in frontal impacts than in side impacts.
Table 3.1
Weight factors
Box 1: Adult Occupant Protection Frontal

75%

Box 2: Adult Occupant Protection Side25%

The overall weighted score is calculated as follows:
100 x (3 x Front integer + Side integer) / 64 = % overall score

Rounding

The following rounding rules will be applied in the calculation of the overall rating.
•••

Data is entered to 2 decimal places.
Intermediate calculations (e.g. calculations needed to derive parameters which are thenused to calculate scores) are not rounded.
Calculation of points scores (e.g. for individual body regions) are rounded to 3 decimal
points e.g. a head score of 3.1238 in frontal impact would be rounded to 3.124.

Version 1.0April 20163•The total points score in each test is the sum of scores rounded to the nearest integer e.g.
11.9 points for side test becomes 12 points.

•The overall weighted score is calculated as follows:
100 x (3 x Front integer + Side integer) / 64 = % overall score

Worked examples:
Vehicle A scores 4 points in frontal and 8 points in side tests.
100 x (3 x 4 + 8) / 64 = 31.25% which falls into the 1 star range.

Vehicle B scores 12 points in frontal and 12 points in side tests.
100 x (3 x 12 + 12) / 64 = 75% which falls into the 5 star range.
