MX5 too slow

I'm driving the MX-5 ND 2.0 in real life. Such a nice and amazing little sportscar to drive.
Driving on the german Autobahn its easy to get 200km/h in 5th gear (before finally shifting into 6th and reaching top speeds, which takes a little bit longer than).
Whenever possible i'm trying to avoid the Autobahn and prefer to drive on land roads. This is much more fun and something the car is best for...

Nevertheless driving fast and taking corners (with both, the standard and the MX5 Cup cars) in AC is fun, too.
But... i'm wondering not to achive 200 km/h at all! Even on tracks like Monza, it's not possible.

I this context i also do not get faster speeds adjusting the setup.
Higher tire pressure etc. should gain in more speed, which does not work.
I also do not notice any slipstream effects on long straights.

What's wrong here? Are the physics are not fully/finally implemented in terms of the setups?
Ars the MX5 specifications wrong here?

I'm driving on PS4 with a standard DS and fully functioning controller (nothing wrong with the buttons).

 

I don't think there's an issue.

1. Monza is not nearly as long as an autobahn, so it unlikely you're going to acheive the same top speeds there.

2. I can reach 120mph (193kph) at monza, stock setup. Considering IRL speedometers usually overestimate speeds by 10% or so, I'd say that'd be an indicated 212kph IRL.

3. Increasing tyre pressures will not increase top speed unless you are already gearing limited (which you are not since you are still accelerating at the end of the straight).

Edit:

Also, on an Autobahn mod track I can reach 206kph in 5th gear, and 214kph in 6th.

 

Hi Racer4711,
I did a short test with the Mx-5 ND and could get 202 km/h in 5th gear before Parabolica turn at Monza 66 Road Course layout. I could get that speed at every single lap, so I think that in the PC current build (AC 1.11.4) the car is fine.
I didn't test the Cup version though, only the ND. Screenshot and replay of a few laps are attached, setup was pure default (just pressed "drive").
Where I agree 100% with you is that almost every car was slower in AC up to version 1.11.3 (if I remember correctly). Unfortunately the difference in patches delivery between PC and Console is something that nor Kunos neither CM505 can sort, depending on how Microsoft and Sony schedule the updates. I hope it won't take long to be everybody on the very same build.
Have fun!
