The herringbone gear is a trademark of Citro?n products. This kind of gear makes very little noise during operation.

Citroen has three car series: sedans, SUVs and MPVs. Among them, the sedans on sale include six models: classic Sega, new Elysee, C4 Sega, Citroen C4L, Citroen C5 and Citroen C6.

In 1913, Andre Citro?n established a gear factory with 11 employees to produce steel herringbone gears, and used herringbone gears as the trademark of Citro?n's products. This kind of gear makes very little noise during operation. Only six years later, Citro?n produced its first car and used the "double herringbone" as its trademark. The "double herringbone" represents Citro?n's principle: Citro?n cars should be at the highest level technically, yet be affordable in terms of price. Later, Citroen organized two trips across the African continent and across the Asian continent, which made Citroen cars famous. French people are cheerful by nature, love to be fashionable, and like novelty and beauty. "Citro?n" cars embody this French character, exuding the romantic atmosphere of France every moment.
