For this MOC I set out to create a completely authentic model of an existing car. Many of the cool, modern super cars most vehicle builders build are unrealistic because the functions of the car can't all be replicated using Technic. So with that in mind, I chose the humble Toyota Hilux...
About this creation

FRONT VIEW
The exterior of the truck was really not a major component of the build, which explains why I left the back of the Hilux bare! (I'll try put a better pic of it up soon). I do actually prefer that look anyway, and I have seen Hilux's without the trailer/container on the back, but I didn't have enough parts to make it even if I wanted to. The proportions are all done based on the wheel size (81.6mm wheels from the famous 8880 supercar). I wanted to go white for panelling but I was way short of parts there, so I had to go with blue (from the blue tow truck set). Even with the blue there wasn't enough parts which is why I added the racing stripes to take up a bit of room. Hood and doors are openable, no door handles on the doors though, they're just held in by a pin.


UNDERSIDE
Now here's where it gets technical...(no pun intended), the Hilux has rear, front and mid diffs, and it's the middle one you can see here. The red clutch beside it is a part of the 'drive selector', this selects between rear wheel drive and all wheel drive (you'll see later where the lever is by the drivers seat). I'm not sure whether the real Hilux has this function, but I assumed it does. To the right of the diff, deep in the chassis you can see more red clutches which are part of the 5 speed + reverse transmission. I based this gearbox on an existing design because it is a very good design and I can't be bothered redesigning it to make it original!

IT IS NOT RC, a realistic drivetrain in Technic does not neccessarily mean a strong one!

The flexible connector running across the underside is a part of the brakes, it goes to the brake pedal. You can also see a bit of gearing on the bottom left which is part of the rear brakes mechanism. Another feature I have included for authenticity is the chassis design. I have copied the exact same 'ladder' structure of the original chassis; two main beams with cross struts like a ladder.



INTERIOR
I have used red parts here to show the functioning parts, the gear stick as mentioned previously is 5 speed + reverse, however, it is not the normal configuration; reverse is where 1st usually is and the rest are pushed along one spot (I hope that's not too much of a sin). The hand brake, behind that, simply jams a gear going to the mid diff, so both axles are stopped. And finally the drive selector lever at the back there. Oh and I almost forgot the steering, it is Ackerman steering (if you don't know what that is, google it)



LDD REAR AXLE- LEAF SPRINGS
I did the rear axle up on LDD 4 (lovely program). This is perhaps my favourite feature of the whole build. The original Hilux has leaf spring suspension on it's rear axle so I replicated it with the flexi connectors you can see here. Every suspension system must have both a spring and a shock absorber, the flexi connectors ('leaf springs') provide the spring, and then a shock absorber is added to damp the spring. Technic shock absorbers are just spring's that look like shock absorbers, so that's why I've got a 'shock absorber' on there as well as the leaf spings.




CLUTCH DISENGAGED
Another feature I've put in for authenticity is the clutch. Here it is disengaged. The clutch is just a rubber wheel and a plate forced together by an actuator (which goes to a pedal).


CLUTCH ENGAGED
This is the clutch with the pedal out, so it is engaged.





PEDALS
Both the Brake pedal and the Clutch pedal are functional, (the accelerator is not obviously). The brake pedal is a little hard to see as it doesn't have a small pin in it, but it's between the clutch and accelerator as per usual.



FRONT AXLE
The front axle is where most of the design time was spent. Inspired a lot by Sheepo's work in his Porsche, I've included a positive camber angle, a castor angle, drum brakes, independent suspension and steering... a lot to fit in a small space!
A positive Camber is the outward tilt of the wheels so that the wheel touches the ground below it's steering pivot, makes for better steering. The Castor angle is the forward tilt of the steering pivot so that the wheel touches the ground behind an imaginary extension of the pivot. This allows the wheels to straighten up after cornering. Again, if you want more info, Google has answers!

Thank you! It was a mission, but I got those pedals done eventually :)

Technically brilliant ! Really clever front suspension layout, and very well done for connecting up the clutch and brake pedals ! I have not seen the outer tubes of the flexi cables used as leaf springs before. Some excellent ideas here, well thought out. Top marks !

Very nice functions! And I even like the color...
