Beijing Automotive Industry Holding Co. Ltd. detailed its interest in General Motors Corp.'s (GMGMQ) European unit Adam Opel GmbH - it wants to get its hands on the U.S. automaker's technologies, including alternative drive trains.

BAIC said in a document outlining a takeover offer that access to GM's advanced technology was the "key driver" for its bid.

According to the document, GM would have to "license all alternative propulsion technologies (i.e. hybrid, fuel cells)" to Opel, including the new company's planned Chinese operations.

BAIC plans to invest $2.25 billion in Opel in China to ramp up production there by 2015. It wants to expand production in China to 485,000 Opel cars by that date and plans to build a network of 400 dealerships by then, according to the document. The document, which was reviewed by Dow Jones Newswires, is addressed to GM, dated July 2 and signed by BAIC Chairman Heyi Xu.

BAIC is offering EUR660 million in equity for a 51% stake in Opel, with GM retaining a 49% stake.

"Industrialization of a developing country such as China needs to have access to intellectual property. This is a top priority for the Chinese government, which has mandated selective industry leaders such as (BAIC) to invest into overseas companies possessing extensive (intellectual property), advanced technology, and a strong (research and development) team," BAIC said in the document.

BAIC said it was "prepared to continue in principle the royalty-bearing license from GM," but with some modifications such as adapting production platforms "to the specific needs of the Chinese market."

These modifications would be the intellectual property of BAIC, but GM would be able to use them for free.

BAIC said it would expect royalty payments to GM for two important new production platforms, Delta and Epsilon, to be lowered to 3.5% from 5%. Many of GM's compact front-wheel drive autos are based on the Delta platform. The Epsilon platform is used for mid-size front-wheel drive vehicles.

BAIC's bid for Opel is aimed at outpacing Canadian auto supplier Magna International Inc. (MGA) in the race for Opel.

Magna is the front runner to clinch the deal with GM after it signed in May a non-exclusive memorandum of understanding to acquire a majority stake in Opel and British brand Vauxhall as part of a bid backed by Russia's Sberbank Rossia (SBER.RS) and automaker OAO GAZ Group (GAZA.RS).

As part of its offer, BAIC plans to establish a holding company for Opel in Germany and would require EUR2.64 billion in state-guaranteed loans.

BAIC would cut 7,584 staff in Europe, with Germany accounting for 3,018 of those jobs, which is less than GM had outlined under its own viability plan.

The Chinese company said it would contemplate closing only Opel's Belgian plant in Antwerp, but would keep the company's German plants. It would, however, idle Opel's German plant in Eisenach for two years and resume production there in 2013 with the small Corsa model.

BAIC plans to import 10,000 Opel cars, mainly the Astra, Zafira, Corsa and Meriva models, into China in 2010 and 50,000 vehicles in 2011. BAIC would start local production of the Corsa, Meriva, Zafira, Antara and Astra models and the predecessor Vectra model in China in 2012 with overall production totaling 200,000 vehicles.

GM's existing China operation has been among its most robust, with unit sales rising 38% to more than 800,000 in the first half of 2009. The company sells its Buick and Cadillac brands alongside those manufactured through its SAIC-GM-Wuling Automobile joint venture.
