And, the weather conditions, altitude, and weight of the drivers foot If they fully test the car, as they did numerous times with the 7th generation, the numbers can be different for many reasons beyond the cars' control, too. So, we can't automatically assume it is slower or faster based on the first fullly instrumented test. I am sure Honda engineered it for comparable to improved performance. But, this generation also seems to be on more of a "green" trend (dispite the added weight).
