Audi or BMW, who is more advanced in technology and technology?

Some people say it must be BMW. You should know that BMW is proud of its naturally aspirated engine and perfect control, while Audi is famous for its attractive cost performance. Its turbocharged engine and stratified direct fuel injection technology still make BMW bow its head in front of it! For a small list, like Audi's TT, Germany's sales last year surpassed Porsche, which ranked first in recent years! Visible its strength! Overall, BMW is better, not wrong, but two words-more expensive!
