Thanks for that review!! I too questioned my engine choice lol, but i appreciate the feedback.

I recommend avoiding the DOHC-5 setup. It’s extremely rare: only a few engines, like some late '90s Ferraris or the 4A-GE Silvertop, actually used it. A DOHC-4 configuration would be a much more realistic and widely-used choice.

The last use of 5v DOHC was the VW/Audi group, whose 5v four-, six-, and 8-cylinder engines remained in production well into the 2000s, until they were all phased out in favor of 4v equivalents, as the link below explains.

And regarding the exhaust flow issue:

@Er_Foxone

Also, when I saw that the flow used by the exhaust was almost 200% I was stunned.

My hunch is that the exhaust diameter is a whole inch (25.4mm) too narrow.

@Er_Foxone

Im confused about the flow being used by the exhaust almost at 200% thing. I thought that the lines had to be at or near 100 at the end of the rpm range for economy? Thats how I interpreted the Automation videos.

[Er_Foxone]

That’s strange, from the engine I saw the flow was about 189%

A Car for Sapporo

It’s judging time!

26 June 2025: Sapporo Head of Car Concepts and Projects would enter his office: He would notice the akan wasn't the only car to check, so he would continue. After opening another folder he would find the project "Sapporo Daisetsuzan"

After checking the chassis information and specifications, he would say:
“I don’t know what this car is supposed to be… Why would you put a monocoque on a pickup truck? And again, dual overhead cam with 5 valves per cylinder… The bottom end is mostly made of cast, which is good considering it’s a pickup and the average customer does NOT want high service costs. Engine’s pretty reliable aswell. Why AWD and not 4x4?”
Design doesn’t look very Sapporo-ish except for the black fascia between the 2 headlights and a bit in the back, but the car does look nice, it just doesn’t look good for Sapporo."

Review

So deciding what vote to give to this car was quite difficult because it had the good design and everything but it missed on loads of things that had it become a non-winner.
I don’t honestly understand the use of monocoque on a build such as a pickup. I like seeing that even using cast parts you managed to get quite some reliability and power, but sadly not enough torque, that is essential in a pickup truck. This time flow was excellent with everything being under 100%.
I don’t understand why would u put a front vented disc with 4 pistons and put just 1 piston in the back.
Same thing as last build, why DOHC-5 .
Overall the build is good but there were some things that you could’ve refined that would’ve had made this car a winner.
I also recommend adding a speed limiter considering this is a truck.

That’s all for today!
Many thanks to @Ultimate_Billy for their participation in this challenge.
