I did add new fillup, 5.1l/100km, which is not so bad considering it was mostly short trips, also lower grill block seem not to matter much with those two gaps, engine is not staying warm, so might put upper grille block there too at least while weather warms up.
I made also coast down test from 20kph to 10kph, so that aerodynamics are not affecting much, this yield result CRR of 0.0098 which of course still contains some of the drivetrain friction, but clearly that low speed is important for testing.
As side effect cd did jump to above 0.4, it might be true as there is hole at other end of bumper, actually there is nothing left from bumper, which probably causes some drag as front of wheel and inner fender are completely exposed.
Next task is to put some covering there, if those sub zero temps just would cease.
I was attempting to gather some data from hills around here, but it was not quite a success, all did look fine but no log, also backup gps refused to work with pc, so I was left empty handed.
Must check if I have earlier data from that, it might be interesting to plot with speeds.
