    Was Jeremy Clarkson right that the front end lifts at high speed?

    His exact words were that past 130mp/h the front end lifts and the steering becomes light, does anyone have experience of this?

    It is probably true of the early cars but it is relative. I expect it is still fairly stable even at these speeds. Will you be heading passed 130 mph often? If yes, the genuine front splitter is supposed to actually work adding a significant amount of downforce at the front!!! I have seen 150 or so on mine and there was no problem with lift. The standard suspension setting is better at speed though than the too stiff dynamic setting which is better for slower, windy roads.

    Surely this is academic since none of us will responsibly achieve that speed in the UK on the public road.

    Granted that early one Sunday morning one might see such a speed, briefly, on a deserted stretch of motorway.

    Personally I’d bow to Clarkson’s more comprehensive experience of very high speed driving than my own and believe him, in respect of the early 2006/7 XK, like mine, at least.

    On the other hand, if you’re asking because you plan to do some track driving, then you may get a more comprehensive answer from a member with such experience.

    If you're planning on just blasting down the Autobahn (once travel restrictions lifted etc etc) then I don't think it would be too much of an issue anyway as the turns are all wide and sweeping...

    The OP does not state where he/she is located. On a lightly loaded Autobahn, in a stable car, one can easily do 110-130 mph and it really does help cover ground effectively. Much more is mainly for fun and maybe public roads are not the right place for it though many Germans do it regularly. When the traffic is denser, attempting to go faster than the rest is pretty futile.

    On most tracks, you will rarely see 130 mph in a heavy 300 bhp car, so not that much of a hitter either unless you have it pedal to the metal at Döttinger Höhe

    I'm not sure. For mere mortals, any curve at 140 mph amongst other traffic is significant enough and I have seen some pretty "tight" bend here too where 80 plus seems fast!

    I have often thought of crossing the Nürburgring off of my bucket list, but I'm not sure that they would put up with an X351 going at 29 mph using indicators to pass cyclists! (... let alone slowing for puddles, in case they hid a pothole)

    I believe it was the spoiler blamed for pushing the back down, causing the front to lift. So presumably a stiffer suspension would fare a little better.

    So add something that creates a problem, then add something else to try to counter it... if you want to do 130mph+ maybe just get rid of the spoiler, which nice though it is I can't think is much more than eye-candy.

    XKs are not racing cars, they're grand tourers.

    If Jeremy couldn't hold the nose down with his ample bulk , then probably some.of us have no hope.

    I have taken mine up to 145 on an airfield but that was in a straight line. No issues but with a later car, better suspension, super grippy MPS4S's and polybushes I didn't anticipate any

    Has OP returned or just a trolling 1 post wonder?
