Établissements Henry Précloux

The Établissements Henry Precloux commenced building light cars in Courbevoie (Paris) in 1921. In 1926 they incorporated Automobiles Bignan. In 1929 production was halted. A company called Loryc also license-built E.H.P. cars in Spain.

E.H.P. focused on small and lightweight automobiles. Originally they used a Ruby 903 cc four-cylinder, later engines from other manufacturers of up to 1.5 liters were installed. After the Bignan takeover, their 8CV cars were also offered as E.H.P.s. The 8CV was originally fitted with a 1,202 cc and 18 PS CIME engine, later a 20 PS and a 29 PS "Grand Sport" version were added. In 1928 the DU model appeared, fitted with an inline-six of 1,300 cc.

The E.H.P. automobiles also saw much competition, participating in four 24 Hours of Le Mans races, coming in second in the 1928 "Index of Thermal Efficiency". An 1,100 cc E.H.P. driven by Boris Ivanowski also won the 1926 24-hour "Bol d'Or" race in St. Germain, with an average speed of 41.6 mph. • Le Mans record: • Year — Pos — Class — No — Drivers — Chassis — Engine — Lap — Speed (km/h) • 1925 — 14 — 1.5 — 39 — Jean d'Aulan René Dély — DT Spéciale — CIME 1,496 cc I4 — 103 — 74.435 • 34 — 1.5 — 38 — Maurice Benoist Michel Doré — 41 — DNF • 1926 — 8 — 1.5 — 37 — Henri de Costier Pierre Bussienne — DS Grand Sport — CIME 1,202 cc I4 — 111 — 80.103 • 27 — 1.5 — 38 — "Morac" Marcel Ballot — 62 — DNF • 34 — 1.5 — 28 — Guy Bouriat Guy Dollfuss — DT Tank — CIME 1,496 cc I4 — 34 — DNF • 1927 — 5 — 1.1 — 26 — Guy Bouriat Pierre Bussienne — DS Spécial — CIME 1,094 cc I4 — 108 — 78.105 • 22 — 1.1 — 27 — Henri De Costier Georges Guignard — 8 — DNF • 1928 — 14 — 1.1 — 36 — Guy Bouriat Pierre Bussienne — Spécial — CIME 1,094 cc I6 — 115 — 83.23
