Audi A4 is a stylish car with look comfort. There are two types of Audi A4 1st petrol engine and 2nd desile engine . Petrol engine is much better than deisle engine because petrol engine started no sound produce and whenevre desile engine is started it produce much sond which is not suit in the personlity of Audi A4 . Then we talk about colour it is comes in mainly 3 colour black, red and blue. I think black is better than blue or red. Lets talk about milage petrol engine is gives on highway is aprox 16 kmpl weather desile engine gives 2kmpl more than petrol engine. For 2 kmpl you should not loose you and your car pessonlity so. If you agree with me you should try black colour petrol engine Audi A4.Thnkss.
