Messieurs Renoult et Delmer étaient les plus petits constructeurs motoristes du monde: 1 seul exemplaire a été produit..
Robur 8 cyl 1100 type race 1928
After having made his debut on the engines of the Avions Voisin cars, then a brief incursion at Bugatti, this engineer enters Amilcar as technical director. The brand, too conservative, regularly refuses its proposals. He left Amilcar with another engineer Mr. Delmer to create a cyclecar from scratch.
In 1927, the brand Robur was born. With a sophisticated front axle and 8-cylinder in-line engine of 1100cc, our two engineers will create the most extraordinary cyclecar ever.
The Duval body is based on a frame made up of two U-shaped spars bridged by three steel sheet cross members and four cross tubes. Friction dampers hold a bridge that comes from an Amilcar. The advance adjustment on the dashboard, the braking system with cables, its system of tension by chain seem straight inspired by Ettore Bugatti.
But the most beautiful piece is this engine, an in-line 8-cylinder of 1080 cm3, resting on ten bearings, it has a dry sump lubrication and overhead valves, with double springs, driven by rockers. The housing forms a single casting with the block. Powered by two Solex carburetors, it develops 48 horsepower at 5500 rpm. It is connected to the rear wheels via a four-speed jaw box.
Messrs. Renoult and Delmer were the smallest engine manufacturers in the world: only one model was produced.
