(Adds hit from UAW strikes in paragraphs 1-4, details on results in paras 5-6 and disposal plan in para 7)

Oct 20 (Reuters) - French car parts maker Forvia on Friday said its quarterly organic sales growth outstripped automotive production across its regions, but warned of a bigger impact from United Auto Workers strikes in the fourth quarter.

The world's seventh largest automotive supplier said the impact of the UAW strikes on its U.S. sales was about 6 million euros ($6.34 million) in the quarter.

It expects a further hit of around 55 million euros this month. In October 2022, its North American sales were around 600 million euros, with around half coming from Ford, GM and Stellantis .

The company, which sells seats, dashboards, electronics, lighting and fuel systems to automakers, posted quarterly sales of 6.53 billion euros, up 10.7% organically from a year earlier.

This was 700 basis points above global car production, which grew 3.7% in the period, Forvia said. In China, the difference was 1,210 basis points, it added.

But on a reported basis, its sales grew only 2.5% due to a 524 million euro hit from converting foreign currencies, namely Chinese yuan, U.S. dollar, Argentinian peso and Turkish lira, into euros.

Forvia, born from Faurecia's takeover of Hella , also said it was starting another 1 billion euro asset disposal plan to reduce its debt and expenses amid persistent inflation and high interest rates.

It reiterated 2023 sales forecast of 26.5 billion to 27.5 billion euros and an operating margin target of 5.2% to 6.2%. ($1 = 0.9456 euros) (Reporting by Michal Aleksandrowicz in Gdansk; editing by Milla Nissi)
