I did a top end run during ED and it topped out at 238 km/h (~148 mph) on my TomTom. Indicated a little over 155 on the speedo...
(after the break-in period, about 1650 on the odometer)
My brother got it on video on his digital camera, but it is kinda hard to see.
The car has Msport package, so it should have the so called 'increased top speed limiter'.
Oh well, I probably won't get too many chances at that kind of speed over here anyways. But still...
