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

It’s like trying to measure your FPS in a video game SOLELY by how many cores your processor has. There are LOTS of other variables involved with the various other parts – RAM speed, bus speed, video card, settings, etc.

In a car you have total CC displacement (i.e how big the cylinders are), intake manifold, exhaust manifold, air intake, lubrication, fuel, transmission, exhaust layout, just to name a few.
