My first try with Multi-Pass Motion Blur from max.
30 samples (i need more for a smooth result)
5000x3333 px on 2 x Titan (6 hours to render)
PT 7 bounces.
Scene created with raiclone for road and railing, and multiscatter for grass and trees.
HDR light.

thanks glimpse,
yes, very nice for inspiration.
This is my first try, for the next one will try to make some more landscape for the scene.
I recently discovered the posibility to render with motion blur, even if this means to use multi-pass (hope that soon will no longer need that :D )
I kinda like automotive render, even photography (a few days ago i made myself a custom car rig so i need to do some more stuff)
Maybe in the future i'll integrate some cg scenes in car photography.

6 hours With 2 GPU ? You should reconsider your workflow. Octane is not that slow. You must be leading Octane to calculate something that it shouldn`t.

@karanis & solomon, yes, one render took 6 hours, I rendered 5000x3333px, 30 prepases (with motion-blur takes around 2.5 times more that a normal render)
My scene consists only from geometry (trees and even grass ) and as you can see it has difuse sss, so it's taking longer this way.
Yes I am not verry happy about the speed, but this is my starting point, hope we will receive real motion blur soon, and renders will take 30 minutes :D
Here are some more cameras.

to be able to use motion blur you have to use default max camera, and enable Multi-Pass Effect, and choose from the drop-down menu Motion Blur set Deither to 0
The number of prepases (default is 12) will be the number of renders it will make and will composit in a single image that will have motion blur efect.
But take in consideration that if you need a 1000 sample picture, the number of passes you need for each prepass is 1000/12 if you set for 12 prepases. If your motion blur si very big, 12 prepasses is not enough, 30 will give you a better result.
Be aware that you can not see the motion blur effect in octane render preview window, you cand only see it in the Max Render Window.
