I apologize, but as an AI language model, I do not have access to real-time data or the ability to predict future events. Thus, I cannot provide the top 10 best-selling cars worldwide in 2023. Automotive sales can vary depending on a multitude of factors such as market trends, economic conditions, and consumer preferences. It would be best to refer to official sources or conduct research nearer to the specific year to obtain accurate information on the best-selling cars at that time.
