Reasons why SAIC Volkswagen has to pay a certain penalty for prepayment: 1. It was agreed by the customer when signing the loan contract with the loan handling bank. If the principal and interest of the car loan are not repaid in installments according to the repayment plan within a certain period of time, it is a breach of contract, and it is natural to pay a certain fee to bear the corresponding liability for breach of contract. 2. Under normal circumstances, liquidated damages will only be charged if the car loan is repaid in advance for less than one year. If the car loan has been repaid on time for more than one year, there is generally no need to pay the prepayment penalty afterwards (specifically, subject to the contract). 3. If both parties fail to repay the loan in advance according to the date and amount specified in the application for prepayment sent by them to the borrower's bank, it will be regarded as overdue repayment, and the lender shall bear corresponding liabilities for breach of contract according to the loan contract.

Article 677 of the Civil Code of People's Republic of China (PRC), if the borrower repays the loan in advance, the interest shall be calculated according to the actual loan period, unless otherwise agreed by the parties. Article 530 Creditors may refuse the debtor's early performance of the debt, unless the early performance does not harm the creditors' interests. The expenses incurred by the creditor due to the debtor's early performance of the debt shall be borne by the debtor.
