==Career highlights==
He participated in 38 [[Formula One]] World Championship Grands Prix, debuting on 13 May 1950.  He achieved 2 podiums, and scored a total of 18 championship points. He won the [[Dutch Grand Prix]] twice in consecutive years between 1950 and 1951, the Circuit d'Albi, Grand-Prix de l'Albigeois and the [[24 Hours of Le Mans]] with his son [[Jean-Louis Rosier]]. Rosier owned the Renault dealership of Clermont-Ferrand.<ref name=joe>''Rosier First In Auto Race'', [[New York Times]], June 26, 1950, Page 36.</ref>

In 2016, in an academic paper that reported a mathematical modeling study that assessed the relative influence of driver and machine, Rosier was ranked the 19th best Formula One driver of all time.<ref>{{cite web |title=The Top 50 F1 drivers of all time, regardless of what they were driving |first=Mike |last=Hanlon |date=2016-05-12 |access-date=2017-12-23 |url=https://newatlas.com/go/43147/ |work=New Atlas }}{{Dead link|date=March 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

==Formula One and sports car competition==

Rosier finished 4th at [[Silverstone Circuit|Silverstone]] in a [[Talbot (automobile)|Talbot]], in October 1948. The event was the [[1948 British Grand Prix|RAC International Grand Prix]], the first grand prix to be held in [[England]] since 1927.<ref>"Grand Prix To Villoresi", ''New York Times'', October 3, 1948, Page S10.</ref> He drove a 4.5-liter, unsupercharged [[Talbot-Lago]] to 3rd place at the 1949 British Grand Prix at Silverstone. He was a lap behind the winner with a speed of {{convert|76.21|mi/h|km/h|2}}.<ref>''De Graffenried Annexes Grand Prix Auto Classic'', ''New York Times'', May 15, 1949, Page S6.</ref>
Rosier won an International Grand Prix at [[Circuit de Spa-Francorchamps|Spa-Francorchamps]] in June 1949. He piloted a Talbot in the {{convert|500|km|mi|adj=on}}, 32-lap event, achieving a time of 3 hours, 15 minutes, and 17 seconds. He assumed the lead after 23 laps, coming across the finish line ahead of [[Luigi Villoresi]].<ref>"Rosier Captures Auto Race", ''New York Times'', June 20, 1949, Page 24.</ref>
Rosier won the [[1950 24 Hours of Le Mans]] in a blue Talbot. He teamed up with his son [[Jean-Louis Rosier]] who only drove two laps during the race, which means Louis won the race practically by himself. He finished one lap ahead of Pierre Meyrat who drove a car of the same [[marque]]. The Rosiers covered 256 laps, {{convert|2163|mi|km}}, in 23:54:2.2.<ref name=joe/> Rosier captured the Grand Prix d'Albi in [[Albi, France]] in May 1953. He drove a [[Scuderia Ferrari|Ferrari]], covering the 18 laps of the finals, {{convert|160|km|mi}}, in 56:36:8. He averaged {{convert|160|km/h|mi/h|2}}.<ref>''Frenchman Wins Automobile Race'', [[Los Angeles Times]], June 1, 1953, Page C4.</ref> Rosier placed second in a Ferrari at
a Grand Prix in [[Aix les Bains Circuit du Lac|Aix-Les-Bains]], in July 1953. His time was 2:24:48.1.<ref>''Bayol Takes Auto Race'', New York Times, July 27, 1953, Page 22.</ref> In April 1956 Rosier finished 4th in a [[Maserati in motorsport|Maserati]], in a 201-mile race at [[Aintree]]. [[Stirling Moss]] drove a blue Maserati to victory in the 67-lap event for Formula One cars, with an average speed of {{convert|84.24|mi/h|km/h|2}}.<ref>''Moss' Maserati Takes 201-mile Aintree Race'', April 22, 1956, Page 205.</ref> Rosier finished 5th at the [[1956 German Grand Prix]] behind the wheel of a Maserati.<ref>"Fangio Captures Race In Germany", ''New York Times'', August 6, 1956, Page 37.</ref>

== Écurie Rosier ==
{{main|Ecurie Rosier}}
Louis Rosier was the owner and manager of a racing team, the "Ecurie Rosier". Originally set up to run Rosier's [[Talbot-Lago]] T26 (for either Rosier or a guest driver), and later evolved to an actual team running [[Maserati 250F|250F]]s and finally [[Ferrari 500]]s simultaneously for Rosier and another driver. Throughout the 1950s, Écurie Rosier provided drives in Formula One for [[Henri Louveau]], [[Georges Grignard]], [[Louis Chiron]], [[Maurice Trintignant]], [[André Simon (racing driver)|André Simon]] and [[Robert Manzon]].

== Circuit Louis Rosier ==
Louis Rosier was one of the key sponsors of the [[Charade Circuit|Charade race track]]. After World War II, Jean Auchatraire (president of the racing section of the local Automobile Club) and Louis Rosier promoted the idea of a race track around Clermont-Ferrand.<ref name="Charade">{{cite web|url=http://www.racingcircuits.info/europe/france/charade.html |title=Charade |publisher=racingcircuits.info |access-date=31 March 2017}}</ref>

A set of preliminary designs were drawn up for a circuit of a length between 4 and 6&nbsp;km, meeting the latest safety regulations with large parking capacity at a location just outside the city limits on a hilly landscape.

The [[1955 Le Mans disaster|Le Mans disaster]] (death toll: 84 lives) on 11 June 1955 brought the project to a halt.  All race events were postponed. No further events were allowed to take place on temporary urban tracks. Racing events were only to be allowed on dedicated race-tracks, providing that they met a new set of rules. In Clermont-Ferrand, as was the case for many other new race tracks, new safety devices were being imagined and discussed, reviewed and assessed.  But the concept of a "mountain race track" moved forward. It would be the only one of its kind in France.

Auchatraire, Rosier and Raymond Roche (the manager of [[Reims-Gueux]] race track) worked together to get the project accepted by the political community before searching for funding. But Rosier was killed at Montlhéry on 26 October 1956 and would not witness his project come to fruition. The racetrack was opened on 27 July 1958, with the name of its famous founder "Circuit de Charade Louis Rosier".  Soon after, several champions participated in racing events on the track, each of them, including [[Stirling Moss]], making very positive statements about the track and its surrounding.

== Car manufacturer==

Rosier's Renault dealership in Clermont-Ferrand was one of the largest Renault dealerships in France. Rosier's dealership also sold other industrial and farming equipment. The building housing this important business has been destroyed.<ref>{{cite web |url=http://memoiresdestands.hautetfort.com/archive/2007/08/13/demolition-du-garage-de-louis-rosier.html |title=Démolition du garage de Louis Rosier : Mémoire des Stands |access-date=2008-01-19 |url-status=dead |archive-url=https://web.archive.org/web/20080108195513/http://memoiresdestands.hautetfort.com/archive/2007/08/13/demolition-du-garage-de-louis-rosier.html |archive-date=2008-01-08 }} (fr) Rosier dealership</ref>

In 1951, Louis Rosier designed a prototype based on the 4CV Renault.<ref>[http://medias.forum-auto.com/uploads/200412/gwengui_1103465249_brissonneauter.jpg] {{Webarchive|url=https://web.archive.org/web/20160303220614/http://medias.forum-auto.com/uploads/200412/gwengui_1103465249_brissonneauter.jpg|date=2016-03-03}} Logo louis rosier</ref><ref>[https://web.archive.org/web/20080911111258/http://img152.imageshack.us/img152/682/huibroualet0.jpg] Coach Rosier</ref>

In 1953, using the concept of a barchetta that he raced at Le Mans,<ref>[https://web.archive.org/web/20080911111258/http://img155.imageshack.us/img155/2673/4cvrosierbarquette52ya1.jpg] Barchetta Rosier</ref> Rosier, together with Italian coachbuilder Rocco Motto, designed a cabriolet,<ref>[http://www.4cv-renault.com/rogue/rogue.html] The Rogue</ref> still using 4CV Renault sub assemblies. This model was built in a quantity of about 200 units by Brissonneau.<ref>[https://archive.today/20120711183459/http://medias.forum-auto.com/uploads/200412/gwengui_1103465145_brissonneau.jpg] Cabriolet Brissoneau</ref> It was even introduced at a car show in New York.

Some time later he designed a roadster using Renault Frégate elements with an aluminum body developed by Rocco Motto, on a multi-tubular frame. The engine was seriously revised, the body was lightened, the results was an interesting 950&nbsp;kg for 80&nbsp;hp.<ref>[https://web.archive.org/web/20080911111258/http://img126.imageshack.us/img126/913/frgatecoup2fy3xw0.jpg] Frégate Rosier</ref>

==Death==
On 7 October 1956 Louis Rosier was competing in the Coupe du Salon sports car race at [[Autodrome de Linas-Montlhéry|Montlhéry]] in a [[Ferrari Monza|Ferrari 750 Monza]].<ref>{{cite web|url=https://www.racingsportscars.com/results/Montlhery-1956-10-07.html|title=XIIe Coupe du Salon - Voitures Sport International|accessdate=2022-10-16}}</ref> During the race he crashed, sustaining head injuries. Three weeks later, on 29 October 1956, Rosier succumbed to the injuries received in the crash.<ref>''French Driver Dies'', Los Angeles Times, October 30, 1956, Page C4.</ref>
