So far I have a long list of cars that can go past 250 MPH, but my Ferrari 458 Speciale is the fastest with 274 MPH (I got my tune shared if anyone is alright with it, you don’t have to at all, I’m just letting you know. lol)
But what is your fastest car?
Mine is Lamborgini Huracan LP 610-4 Horizon Edition

It dose a top speed on 250MPH.
But that is not tuned only upgraded,
but ill think ill do this to my quest now!
I’ll see if I can make it go faster! 
I have only used it for one simple race,
so haven’t needed to change the setup,
but now you gave me a reason! 
Nice, the Huracan should be able to be tuned to be about 265-270, always see them holding up nicely in drag races. All I do is drag lol, my Speciale was only like a 20 minute job.
I got the Dart up to 271mph set to drag obviously lol… Though I think it is the Datsun Drag OP Car in Horizon 3

I made this graphic for a Replica M6 and then decided to add it to the Dart looks sweet!
Mine is the Ford Mustang King Cobra R, Reaches an exceeding speed of 286 MPH with a honorable name as The Dark Killer with 19.1 Lateral G’s. It has a chance to even kill The DType
My fastest car is the Ford GT Horizon Edition. I went around 430km/h with it
