Yes, 320 indicated on speedo.

Hows the accuracy? The M3 abs sensor & gps sensors on my car show that my speedo is out about 7% out up to 120ish and gets more inaccurate the higher the speed but the trip computer/odometer is accurate.

320, which is probably around 308-310kmh actual ... ...

that's quick....

I think I took some video of the GPS reading and the speedo at a constant speed around 230 or so and they were pretty close - I can't remember now though whether it was in an M5 or the Gallardo.

in the 550i, when the GPS showed 108kmh, my car speedo indicated 110kmh.

If my memory serves me correctly the separate GPS I had in the car was indicating about 8-10k's less at speeds over 270k's, I wasn't constantly checking both as you would imagine  my eyes were transfixed on the road, but I was certainly interested to look when it got above 310

Sh1t that is quick! How did it handle at those speeds? What revs and I assume you were is 7th?

It wasn't the Gallardo.  With the speedo showing 110km/h, the TomTom said 103.

It was very solid at 220-270, you really new you were going those speeds, IMO the feeling of speed increases exponentially once above 250, you really know your going fast then, at anything above 270 you didn't want to hit a big bump. All present, I'm sure will attest to how easy & great it felt cruising at 180-250  with a few spurts beyond that and 2 warp speed runs at a specific 20km section. 7th gear at about 7400rpm

Exactly how I've always described it - most cars I'm happy up to 240 or so, but 250+ and you are really really interested in what's in front of you - every 10kph feels like another 100kph.

the one time i did 300kph+ it felt like slow motion.....and like i was on the big dipper when i went over a slight crest in the road.

this was long long ago.
