I can't see why where Accord consume as low as 7.5 kW > ACRX consume 12 kW. My bearings then must be much worse, or tires, > or pads dragging or combination of above. > > Besides ACRX has belly pan Accord doesn't. Hmm....
True enough. I've been mystified by this for quite a while, as you know. > ACRX is sure heavier (3380 lb) but not by as much as make > up for kW difference (most of which is windage at 65 mph). One thing to remember is that 3100 lbs in a accord frame is not really stressing the frame that much.. it's well within GVWR. 3380 lbs in a CRX is stressing the bearings, tires, etc well beyond what the designers expected the stresses to be - there may be some nonlinear phenomenon. > My C_d is 0.29, yours is 0.34 (actually it's Integra, same shape) I think it's 0.32 actually. > Something is off. We go through this about once a year, haven't come up with any successful explanation yet. Can you get 4-corner weights for ACRX, by the way?
