1999 F-250 Super Duty transformed into a rolling wind tunnel.
Bidding has just ended on one of the most unique, wonderfully weird vehicles we've ever had the privilege of stumbling upon in our eBay vehicle hunting: a rolling wind tunnel built from a 1999 Ford F-250 Super Duty diesel truck. Featuring a stripped interior, a ridiculously shallow bubble roof, and a long, sloping rear tail where, presumably, a truck bed once sat, the truck has been transformed into a total freak - and we mean that in a good way.
What would the neighbors say? What would your wife say? Could you even survive, driving this funny-looking space age greenhouse on a hot summer day, baking under the polycarbonate bubble roof? And what in Thor's name does one actually DO with such a vehicle, anyway?
These are the questions that will keep us up at night.
Here's the scoop: A company by the name of XCOR Aerospace, which folded in late 2017, bought and modified the 1999 Ford F-250 to use as a rolling wind tunnel. If you haven't priced one out recently, wind tunnels are, like, insanely expensive. A less-expensive alternative is using a towing vehicle as a rolling wind tunnel by modifying the body to make it as smooth slippery as possible.
To that end, this truck has that unique bubble roof we mentioned, plus a long, tapered tail that seems to be crafted from aluminum, and solid closed-face wheels.
Add all that up and you have one singularly strange truck - but a remarkably effective wind tunnel, we'd imagine, not to mention one heck of a conversation starter.
"You've got an old Jaguar E-Type? Oh, that's nice. My car is a wind tunnel."
This 1999 Ford F-250 diesel wind tunnel - or "trunnel," as the eBay listing calls it - ended up going for just $3,359.99, which is a steal. We think. Actually, we have no idea what the going rate is here. But it's certainly cheap for a wind tunnel.
