Hey Phil -

Thanks for the kind words.

Here's a couple more rendered images from our Augmented Reality program.

It looks awwsome. Sorry for probably stupid question ( my closest experience with trucking is from playing few times 18 wheels of steel PC game, so negligible). I was living under impression that most of the owners-operators owns just a rig and tows whatever their contractor needs to haul.
Your setup seems to give best results with tractor+trailer combo. So how is it? Do truckers usually own both tractor and trailer or not? What performance do you expect with standard trailer? Have you tested tractor alone? Do you plan something for flatbeds, too? Inflatable boat-tail?

Thanks. This is an integrated prototype concept vehicle, not an owner operator vehicle. One must have an integrated aerodynamic unit, with components that work in harmony with each other, for the best aerodynamics and fuel efficiency.

Many owner operators in the U.S. lease to a large carrier, operate under the carriers authority, and use the carriers trailer. Many other owner operators lease to a large carrier and use their own trailer. And a lot of owner operators have their own operating authority and own all of the equipment.

This tractor will never be hooked up to standard trailer. We are striving for the best Class 8 truck fuel efficiency in the world, and a standard trailer would only detract from that.

We have not tested anything yet. We are currently wrapping up the build.

Flatbed versions, or an inflatable boat-tail, are not in the cards.

Car Hacker's Handbook

Have you done a threat assessment on your onboard systems?

Quote:
The Car Hacker’s Handbook will give you a deeper understanding of the computer systems and embedded software in modern Â*vehicles. It begins by examining vulnerabilities and providing detailed explanations of communications over the CAN bus and Â*between devices and systems.

Then, once you have an understanding of a Â*vehicle’s communication network, you’ll learn how to Â*intercept data and perform specific hacks to track vehicles, unlock doors, glitch engines, flood communication, and more. With a focus on low-cost, open source hacking tools such as Metasploit, Wireshark, Kayak, can-utils, and Â*ChipWhisperer, The Car Hacker’s Handbook will show you how to:

Build an accurate threat model for your vehicle
Reverse engineer the CAN bus to fake engine signals
Exploit vulnerabilities in diagnostic and data-logging systems
Hack the ECU and other firmware and embedded systems
Feed exploits through infotainment and vehicle-to-vehicle communication systems
Override factory settings with performance-tuning techniques
Build physical and virtual test benches to try out exploits safely

If you’re curious about automotive security and have the urge to hack a two-ton computer, make The Car Hacker’s Handbook your first stop.

- I am aware of it, but iirc you did extensive CFD testing and that was on my mind. I should probably express myself more clearly. But as you said there is no intention to separate the combo, i assume no cfd study for the truck alone.
Best regards

No, not of the onboard systems. But I have done a threat assessment of the outside of the truck systems, so I run with a .45 ACP and a German shepherd.

We had an aerodynamicist from Honda R&D in Torrence, CA do CFD simulations of the complete truck, and the final version came out to 0.25 Cd, believe it or not.
