I find one of the coolest things about LEGO Techinc is the never-ending variety of car MOCs, both big and small. I was recently traveling through London and was inspired by all the sleek hatchbacks everywhere. So, for my first MOC, one hot hatch:
Its a front engine, flat 4, rear wheel drive car with HOG steering. It has operable doors, hood, and a full tailgate. Detailed with spoiler, lights, and other features.
I wanted something with a simple yet compact drivetrain I could freely design around. I was originally trying to go for an inline engine, but switched to a flat 4 which I could fit a steering rack under and keep the hood as low as possible. I was also able to fit a diff in back under a large trunk.
You can find more images as well as an LDD of the full model here.
Enjoy.
