Sorry for starters. :/.

I have followed your airflow truck project, and you have received very good mileage with it. The first post does not say a word about your company and at least I did get the impression that its totally Shell project. If that is not the case I would rephase the first sentence. We Airflowcompany are building together with Shell... And by comparing that Shell picture for your latest truck it seems pretty much same from outside so at least in the picture there is not anything new.

On third read I got the point, your company name is already there but its not standing out as it should as you are doing the work.

Still what comes to aerodynamics:
- why are all the trailer wheels still open to airflow?
- Why are front wheel bolts are open in airflow?
- No boattaill?
- no sideskirts after rear wheels?

Is the picture on purpose unclear so its difficult to see what is happening where as its so dark?

From the previous truck you built, I would estimate you will build those as well and would do even more tricks to boost mpgs up.
