André Lefebvre (19 August 1894 – 4 May 1964) was a French automobile engineer.
André René Lefebvre was born in Louvres, France (North of Paris, Val d'Oise). He began his career as an aviation engineer working for Voisin, then later for Renault and Citroën. He was also a racing driver and race car designer, and won the 1927 Rallye Monte Carlo.
After completing studies at Supaéro he began to work for Gabriel Voisin in March, 1916. Voisin placed Lefebvre in charge of his Laboratoire where he worked on aviation projects until the end of World War I, and then automobiles. He is particularly noted for creating the Voisin C6 Laboratorie, which was a race car prepared for the 1923 French Grand Prix.
When Voisin ran into business problems in 1931, Lefebvre was recommend to Louis Renault. Renault was persuaded to recruit Lefèbvre by François Lehideux, himself a senior executive within the company (who was also married to the daughter of Renault's brother).
Lefebvre remained with Renault only until 1933, when he was hired by André Citroën to work on the Traction Avant project. After the death of André Citroën in 1935, Lefèbvre continued his work at Citroën, now led by the innovative entrepreneur Pierre-Jules Boulanger, who came to the company from Michelin.
Working with Citroën designers Flaminio Bertoni and Paul Magès, Lefèbvre created four of the most dramatic, boldly designed vehicles of 20th century:
The 1955 Citroën DS placed third in the 1999 Car of the Century competition, behind the Ford Model T and BMC Mini.
