EDIT: For accuracy's sake, the aerodynamics would be worse if it didn't have the tonneau cover over the bed: Urban myth I'm afraid. The whole tailgate up, tailgate down, tonneau cover has been tested before, and tailgate up was found to be most efficient.

Still got a soft spot for VW's and that gold split looks killer. Saw it years ago parked on Dalston high st and it looked great.
Still don't know why there's a trend for a boot sale on the roof though.

The whole tailgate up, tailgate down, tonneau cover has been tested before, and tailgate up was found to be most efficient. my old caddy pickup used to run at least 1/3 of a second quicker with the tail gate down so i wouldn't say urban myth really and a covered bed always makes for less drag as the air can't enter the pickup bed thats why most new trucks come with covers, well that and the fact there's a lot more thieving scrotes about. try driving around in a booted car car with no boot lid and watch how much more fuel you'll use . anyway back on topic great pics love the moving shots

Science is just a collection of theorys that have yet to be proven incorrect. Practical experiments are often best

Science is just a collection of theorys that have yet to be proven incorrect. Practical experiments are often best Yep that has always been my experience as well. I have always found actual experience rather that theoretical BS seems to prove the point having done dragracing for a number of years I various vehicles actually on a drag strip not in a lab or on a computer I have found with a pickup truck its best to have the bed covered or tail gate down if you have no cover . The people who make these trucks also share the same views as they mostly come with covers to help with fuel efficiency but as its in a science paper we we must all be wrong about our experience aye

Mythbusters proved that having the tailgate up is better for mpg, not sure about speed though.

Mythbusters proved that having the tailgate up is better for mpg, not sure about speed though. Matt They also revisited the myth to include tonneau covers in a later episode, and still found tailgate up to me most efficient. More MPG = less drag, less drag = more speed. The trouble with practical experiences is that there will be other variables which need to be taken into account. In a drag race situation the difference between two runs could be reaction time, tyre pressure, gear change, or wheelspin. However if you are concentrating on the tailgate/tonneau issue, it would easy to attribute 'improvements' in a run to perceived alterations made to aerdynamics, rather than taking these other factors into consideration.

Myth busters is a great show to watch but it is just that the TV show. i'm probably wasting my time as you belive what you belive and nobody will be able to tell you other wise but. try looking here www.trucktestdigest.com/PDFfiles/SEMATonneauStudy2007.pdf
