The investment banks are registering a veritable run on the shares of Porsche AG, which is striving to go public.
Shortly after the start of the subscription period on Tuesday, one of the accompanying banks reported that the books were "many times oversubscribed across the entire price range".
Until September 28, Volkswagen is still offering 113.9 million Porsche preferred shares in a range from 76.50 to 82.50 euros.
With an issue volume of 8.7 to 9.4 billion euros, the Stuttgart sports car manufacturer would be the largest IPO in Germany for 25 years.
Volkswagen had secured firm commitments from anchor investors in advance for 40 percent of the issue volume.
This also stimulates the share prices of the automakers, which posted above-average price gains in early trading.
The surcharges ranged from 0.7 percent for BMW to 4.7 percent for Porsche Holding.
Volkswagen prices rose by 2 percent.
In a study, analyst Philippe Houchois from the investment house Jefferies described the spending range as narrow as expected.
At the midpoint of the issuance range for the preferences, the company would be valued at €73.8 billion.
