How fast can a car go with 600 horsepower?

Answer 1

This is dependent on multiple variables, such as drag coefficient, power to weight ratio, rolling resistance, etc.

Most cars that approach 600 horsepower will typically go between 190-225mph.

In some cases, the car is capable of faster speeds, but is limited electronically due to tire safety limitations.

Some Examples (NOT an exhaustive list):

A Ferrari 612 is 532 horsepower and has a top speed of 196mph.

A Lamborghini Aventador is 691 horsepower and has a top speed of 230mph (The Murcielago that it replaced was between 571 and 661 horsepower depending on the year with a top speed between 205 and 212 mph).

The Corvette ZR1 is 638 horsepower with a top speed of 205mph.
