SAIC GM Dong Yue Powertrain makes engines and transmissions at Yantai in Shandong province, China, supplying the assembly plants that build Buick, Chevrolet and Cadillac vehicles for the Chinese market. The plant started in 1999 as Shandong Daewoo Automotive Engine Co., Ltd., a venture between Daewoo Motors and Chinese partners held by the Shandong provincial government, and was taken over in 2005 by the SAIC and General Motors partnership, which retooled it for General Motors designs. It has built the Family I generation three petrol engines and later Ecotec units, and its transmission lines cover the 6T30, 6T40, 6T45 and 6T50 six speed automatics and continuously variable transmissions. Its volumes have followed the decline of the group's Chinese vehicle output through the restructuring of the past two years.
Source
SAIC GM Dong Yue Powertrain Co., Ltd. (SGM DYPT) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from SAIC-GM (Wikipedia), General Motors Company Form 10-K for 2025 (SEC EDGAR) and SAIC Motor corporate history (SAIC Motor). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of SAIC GM Dong Yue Powertrain Co., Ltd. (SGM DYPT) where a holder stated one, and are missing where no holder did.
