Consideration of ‘Family’ in gtr

2. Which families are necessary for gtr?
Family discussion is including ’certification issues’. However primary discussion should be limited to the items necessary to establish ‘test process’, which are;
RLD, to define the criteria of RL correction.
FC, to define the criteria of CO2 regression line.
Gear shift (DHC), to prevent infinity of shift points.
other

3. What parameters are necessary?
RLD, to define the criteria of RL correction.
Similar body style/size. Because these affect to wind-tunnel test result, so RL data correction from the data of different body style/size may have error.
FC, to define the criteria of CO2 regression line.
Device for fuel consumption (e.g. idle stop, cylinder management), body shape, etc. Because these parameter affect to CO2 but not proportional relation with weight/aero/tyre.
Criteria of engine capacity, we think 30% is too much.
