MouldKing® Formula Racing Engine

Let's explore this highly detailed STR13-inspired engine model. Built from 980 precision pieces, this kit replicates the RA617H power unit with stunning accuracy.

The bold red cylinder head and black intake manifolds mirror the real hybrid engine’s aggressive look, while the chrome-plated exhaust pipes capture the complexity of the turbocharged system. Transparent cylinders reveal the pistons moving in sync, powered by an electric motor that simulates a real racing start-up.

This isn’t just a static display—flip the switch and watch the gears drive the pistons up and down, mimicking the heartbeat of a true V6 engine. The gearbox adds another layer of realism, with three selectable modes: low-speed gear, neutral-speed gear, high-speed gear.

A clever reverse-rotation function even allows the engine to spin in the opposite direction. With its functional cooling fan, ERS-inspired radiator, and realistic turbo layout, this model is both an educational project and a thrilling display piece for any motorsport fan.
