An inline-four that runs, sounds and smokes

Inline, Boxer & Rotary collection

An inline-four that runs, sounds and smokes

An inline-four engine built from 931 pieces, 25.5 cm long on a base with a printed nameplate. Switch it on and the electric pistons stroke through the bank, a sound module plays the engine note and a vapour unit breathes smoke through the chrome exhaust, while a four-speed switch changes ratios through visible gear linkage. Bronze cam covers sit over silver casing. Plan on four to six hours of building.

The ultimate assembly experience

Four cylinders, full performance

Bronze cam covers over silver casing across 25.5 cm, with a swept chrome header aimed at the room.

Pistons, sound and smoke

Switch it on: the pistons stroke, the sound module fires the engine note, and vapor breathes through the exhaust.

Change gear on the bench

A four-speed switch drives visible electric gear linkage — the transmission working in plain sight.
