3. Honda pushed the very limit with the hatch angle. They probably figured and optimum compromise between aerodynamics, length, and rear visibility.
Just as a guess, one might raise the hatch lid a couple of inches and achieve better aero. In a couple of weeks I'll probably give that a try. All comments very welcome  |
I'm late to the party ( happens quite often).Just watched the video (an amazing tool!).
The flow looks okay.A bit nervous,but no reverse circulation,so the appraisal that Honda got it right on the ragged edge is confirmed.
On my last trip I tufted the hood blister near the windshield.Those behaved as if they were painted on.They didn't move at all except when encountering gusts or bow,stern waves off big trucks.
The top of the trailer was a bit nervous as was expected,as there was a significant gap remaining.
The lower sides which I could see from the mirrors were VERY nervous,although no recirculation visible.They remain the 'dirtiest' location until completed.
It will be interesting to see the 'raised-hatch' results,and if some of the quaking diminishes.
Nice work HONDA!
Nice tuft-testing Jim,and thanks to Darin and all which made all this happen.
I may lean on all of you as I attempt this same sort of thing.I've got a 7-meg camera with a short video capability.And friends have volunteered to do the chase car driving and videography when the time comes.Again,thanks Mucho!
