I respectfully disagree. But again with this condition: I have an
ideal test route - straight, flat, level, practically devoid of traffic. (I think we've gone through this before!) Also: I will only test with the hybrid system disabled, as it can throw variability into the test (hidden background charging, etc).
Andrew - coastdown testing is an alternative, for sure.
Though
3-Wheeler posted about coastdown testing in his Insight and he had a lot of difficulty getting reliable results, even
without changing anything. I have a few ideas on why he had trouble, and hope to do an Insight coastdown A-B-A test this fall to try out a deep air dam.
