Usually when buying or talking about cars main things are power and top speed.
For measuring cars top speed you need like really long track without bends.
Currently in LFS there is not track like this, so I had to use additional content :P
Some of my logic for achieving top speed was like:
For achieving top speed main factor is gearing, if this is set incorrectly than nothing is good.
Its interesting how turbo cars had problems passing some rpm point in way to top speed, so I had to set lower gear to pass that point.
I tested a bit more with XFG, how does setup affect top speed here are some notes:
Notes for other cars:
Speed was measured using Aonio, when speed did not changed for one minute.
Note: On high speeds like 300+ kmph difference between Aonio and cars speedometer is even five kmph !!!
LFS cars top speed:
Resistance factor
P=F*v
F=c*v^2
--------
P=c*v^3
c=P/v^3
by this site FBM can reach 230 kmph, but I could not
I tried hard with BF1 because this speed of 354 seems too low, since it reaches almost 350 on oval, but also could not do any better.
Now you can talk to friends how fast you car is :P
Hope I didn't miss any number
Comments welcome

Some of my logic for achieving top speed was like:
- set tyre pressure to max (to achieve minimum rolling resistance)
- minimum camber (lowest surface touching ground should also decrease rolling resistance)
- set toe to 0
- adjust gearing that maximum speed is achieved on maximum engine power (from hard track setup with changed final drive ratio, gears independently set in turbo cars)
- hard suspensions with minimum height, but to not touch road
- locked differential
- down force to minimum
- R highest possible number tyres (if car use slick), road cars SUPER tyres if possible

I tested a bit more with XFG, how does setup affect top speed here are some notes:
- if tyre pressure set to minimum top speed will be three kmph lower than maximum tyre pressure
- didn't found any effect of camber settings to top speed
- didn't found any effect of toe settings to top speed
- didn't found any effect of suspension settings to top speed, even when comparing maximum ride height and minimum top speed remains the same
Notes for other cars:
- if car uses slick, R4 is usually faster by 2-3 kmph (FXR)
- ROAD SUPER vs ROAD NORMAL vs KNOBLLY equal top speed (RB4)
- HYBRIDS are one kmph slower than ROAD tyres (RB4)
- Added weight will not decrease top speed, you will only need longer time to achieve it
- When adding restriction to engine power... (see RB4 power/speed table below)
