Why do some V8 cars have more horsepower than other V8 cars?

Question

For example, a V8 Bi-Turbo G63 AMG has 577 BHP and a Twin-Turbo V8 Koeniggsegg has 1160 BHP. How do virtually the same engines have such a large discrepancy?

Answer 1

Cylinders and displacement is not a good estimate of a cars performance. There are many more design elements.

It’s like say two people weigh 250lbs but one can bench press 300lbs while another can do only 150lbs. Why?
