Question: what is the difference between f1 cars and indy cars?
Answer: The difference between F1 and Indy in terms of the engine is that F1 uses a 1.6-liter V-6 whereas the Indy car comes with a 2.2-liter V-6. As both racing cars feature mind-blowing speed, the brake system is extraordinary too to stop the cars right on time with 100% efficiency.
