V8 in the back, electric up front

An LS3 V8 sits right behind the seats and drives the rear wheels through a Subaru STI TY856 six-speed. Up front, a Tesla electric drive unit powers the front axle, which turns the car into a hybrid all-wheel drive.

The front drive unit is designed to come out when I don't need it, so the same car can also run as a pure rear-drive V8.

Printed panels

The body panels are 3D printed. I started with ABS, but it smelled even with ventilation and the layers kept separating, even inside an enclosure. After five attempts without a usable part, I switched to PETG.

Lesson learned on camera: the right material matters more than the right printer settings.

Three modes

The rear wing targets about 200 lbf of downforce at 100 mph. It runs in high-downforce mode about 80 percent of the time, flattens out on the straights to cut drag, and stands up as an air brake under hard braking.

Speed is the priority: every module has to make its move in under half a second.

A flag on every dash

The hub doubles as an in-car race-control screen. At a track day, one computer can link to every car's hub, flash a yellow flag on its screen, and see each car's sector times. That side of the system is being built into Velocity.

2026 Launch Edition

The first merch line is already in the shop: a mug, a tote, a hat and a hoodie, all carrying the PaddockPass mark. It started with transparent decals for shirts and gear and a large back print.
