MetroMPG · 04-17-2015, 11:30 AM

Near perfect conditions yesterday (mild, dry, light to no wind), so I got out to do testing on my usual flat test route, with no other traffic to interfere.

And I have to say: I am super disappointed with the numbers! I've never seen a tail have such a small impact:

2% improvement (1 mpg US) at 90 km/h / 56 mph.

I'll post the full details later on.
