I recently took it upon myself to try to make a general purpose test track for vehicles!
Ever since, I have been making a bunch of fun and silly vehicles.

One idea that caught my eye however, was to try and make a powerwheels-esque car. It surprisingly did fairly well on the track!
But now I want more! >:D

I decided to put both a turbocharger and a supercharger on it, creating a twincharger!
I didn't stop there though! I greatly increased the RPM limit and added a button to disconnect the differential from the wheels, as well as making the wheels a lot larger.

Now I think this really does look like a powerwheels car!

Controls:

A - Reverse
S - Brake
D - Gas
W - Toggle Offroad Suspension
C - Disconnect Differential
1-6 - Select Gear (this car has a 6 speed manual transmission)

All of these controls should work on iPad!


I had a lot of fun making this scene, and even though it's not much, I still really hope you enjoy it.

Word of warning though! This car is quite top heavy and is prone to wheelies and flipping. I haven't actually tested it on this track as of writing this, so no guarantees as to how far it can go...:lol:

EDIT: I've tested it on the track and it can get to the second-to-last ramp at the end (the steepest ramp right before the finish line) before losing grip and rolling off. :lol:

For what it's worth, this did better on the track in my testing than a lot of my other cars, and the only car I've made that I've managed to get past that second-to-last ramp was the Porcelain Dragster -- and that was because of the flushing acting as a rocket boost! :lol:


Some general specs:
Maximum Boost: 4.5 bar (quite unrealistic -- but this whole thing is unrealistic!:lol:)
Engine: Twincharged Spring Inline 3 (scripted 2 stroke)
Transmission: 6-speed manual, can be converted to automatic or continuous by selecting the entire car, entering the script menu, and changing _mode to 1 for automatic or 0 for continuous
Redline: 9000 RPM
Top Speed: 180 MPH / 289 KMH
Drivetrain: AWD, differential can be disconnected from the wheels to rev the engine and transmission before delivering the power all at once to the wheels!
Footprint: ~2 x 1.375 meters

Any item in my scenes can be used with credit.

DISCLAIMER: I know next to nothing about forced induction (superchargers in particular) so...:lol:
This may or may not be similar to how an actual turbo/supercharger works. The way I've implemented it does include turbo lag -- but beyond that I have no idea what I did.:lol:

EDIT: Moved center of mass towards the bottom, it should handle steep slopes and aggressive throttle better now!:lol:

Nicely done! :tup:

I got pretty far along the track, but beyond a certain point, the track becomes nearly impossible!

(unless I cheat by adjusting a few parameters! :lol: )

Thank you! :lol:

I think one thing that could help with the tipping is if I change the drivetrain from AWD to 4x4.

If I engage front-wheel drive, perhaps it wouldn't want to flip! :lol:

At the same time though, traction would be way worse...


EDIT: I tried this and it didn't go very well. Even if I max out the friction on the wheel, it just glitches out at full throttle and doesn't pull the car very well.

You might also try playing around with added weights to offset the center of mass. Maybe more weight on the front portion of the car?
Thank you!

I think I'm going to experiment with tuning in a separate scene to try and make one that's less speedy and more offroad-y. :lol:

My goal is to make one that can actually pass that final ramp! :lol:


I will say though that I will do some significant modifications to the body to make it look more like an offroader! :lol:

That's what I love about Algodoo. You can experiment with different things in order to make your gadget do what you want it to do and you don't have to worry about breaking anything like you would in the real world! :lol:
It was really difficult for me to get far on the mouhtain.
Yeah, I had to use a lot of pause+undos to get as far as I did... :lol:
That's how I drive my real car every day.... by using a lot of pause+undo's to get where I'm going! :lol:
