Net sales of Rmb1,754.4 million (US$212.0 million) for the quarter ended June 30, 2005 represents an increase of 53% compared to the same period last year of Rmb1,149.6 million (US$138.9 million). Total unit sales of 67,581 diesel engines for the quarter ended June 30, 2005 was 65% higher than the same period last year of 40,922 diesel engines.

Total unit sales of 138,514 diesel engines for the six months ended June 30, 2005 was approximately 32% higher than the same period last year of 105,323 diesel engines. This was mainly due to the strong unit sales arising from Yuchai's 6105 medium, 4-series light-duty diesel and industrial engines. The overall gross margin of 24.2% for the six months ended June 30, 2005 was 6.8% lower than the 31.0% gross margin of the same period last year mainly due to product sales mix and higher raw material costs. Yuchai sold 80% more of the lower margins light-duty diesel engines in the first half of 2005 compared to same period 2004. For the six months ended June 30, 2005, selling, general and administrative expenses increased by approximately 18.8% due mainly to higher transport charges and other operating expenses. For the period ended June 30, 2005, trade account receivables and inventories increased as a result of higher sales volume and normal seasonality factors. Bank borrowings have increased for the period ended June 30, 2005 mainly due to increased capital expenditure payments made and higher working capital requirements during the six months ended June 30, 2005. Basic and diluted net income per share for the six months ended June 30, 2005 was Rmb7.29 (US$0.88) compared to a basic and diluted net income per share of Rmb8.32 (US$1.01) for the same period in 2004.

CHINA YUCHAI INTERNATIONAL LIMITED 16 RAFFLES QUAY #26-00 HONG LEONG BUILDING SINGAPORE 048581 TEL : (65) 6220 8411 FAX : (65) 6226 0502 Mr Philip Ting, Director and CFO mentioned that "Yuchai's unit sales growth of approximately 32% in the first half of 2005 demonstrated that demand for trucks and buses remained to be good although CYI's net income has declined by approximately 12% for the six months ended June 30, 2005 due to gross margin decline from product sales mix and higher raw materials costs. Government industry statistics show that in the first half of 2005, there was an increase of approximately 8% in sales of trucks and buses in China compared to the same period last year. Yuchai management believes that the new super heavy-duty diesel engine - 6L/6M (previously called 6113) remains to have a positive outlook, arising from demand for bigger trucks and buses." General Information Yuchai has a strong brand name in China with an extensive sales and marketing network. Yuchai's products are of good quality and provide reliable performance. Yuchai has established itself as a major manufacturer of diesel engines in China with a significant market share. CYI has filed with the U.S. Securities and Exchange Commission a copy of this press release on Form 6-K. A copy of such filing has also been sent to The New York Stock Exchange.
