I would have to agree with Pink on this one........ I would think it's very difficult to achieve 140 on the Prodrive track, it's not big enough for the ST to get to that speed IMO.

I've never been to the track so dont have a clue, it does take quite some time to get up to the very top end speed in any car though...

I was pushing around 95 on the back straight at my Prodrive day, and that was leaving the braking a little late! I've only managed 130mph on the dials (124mph GPS speed), and that was on a huge stretch of motorway. No amount of driving technique or exhaust trickery can make thae difference between 90 odd and 14(2)

Was out driving on a long piece of private road last night and managed to get 134mph and it was just hitting the red line on the rev counter so couldnt get much more. As everyone else has said it was as smooth as anything when i was doing it.

138 MPH reading on sat nav, 98 RON fuel and maybe a tail wind. on a private road of course.

That must be the highest speed yet! How did you get a speed reading off the sat nav though?

You must tell us more about this 'private road' aswell

i hit about 136mph on the a12 towards southend but that was thrashing the arse off it , but again the gps reading on sat nav was showing 131 .
car feels alot quicker now its had a servise so will get back with new speed sunday night

am i the only one who hasn't flogged their ST to death? max i av done is 80mph (on private land of course mr policeman)- any faster and i'd scare myself half to death! mines done 2.5k and its still not opened up properly, still lags a bit. maybe should give it a good thrashing! lol!

I've got 130mph out of my corsa 1.8SRi on the M6 toll, not bad considering the corsa only has 125PS compared to the ST's 150

its probably lighter and it might be geared better

The dial said 150km/h at the time. I haven't really stretched it yet, it's just over a week old.

Oh, that's about 95mph, so not bad for a week old car. i'm guessing taking mine up to 120mph on a downhill stretch of the M1 near Coalville when my i'd had my ST for 2 days was probably a mistake!! So you're behaving better than me
