    Totally agree but you can "judge" gaps by starting to roll and then hitting the go pedal rather than starting from a stop position. You do need to be comfortable with your awareness of the car's response before playing chicken though. I certainly would not cut it too close but now I do not wait until the road is totally clear for fear of lack of response. As I said you will get to know what you can and can't do but need to take it easy at first. A common sense approach is really all that you need.

    Thanks for the responses

    In my uneducated opinion on land rover it seems its common from the responses, and people changing driving styles to suit seems strange to me, yes its a big car, but our 200 was bigger no delay just go, the only other cars I've ever been in that has done this was a old wrx and that was years ago 4cyl, and speaking to my brother his crappy hyundai does it 4cyl and hyundai told him its normal, ill try driving it hard for a while and see how that goes and report back.

    Let's not forget "there's no replacement for displacement"

    The 200 series will ALWAYS launch better than a 2.7 or 3.0 litre turbo diesel, there is no way around this! However generally speaking the lag is minimal and unobtrusive. When it becomes noticeable there is usually an underlying cause... But can be a bear to locate.

    Cheers

    In the 2.7 with one turbo the cause is situational. A certain situation can occasionally catch the car out momentarily. I have one bad intersection to pull into regularly and on super busy mornings I click it into Sport mode and no problems. It actually accelerates surprisingly fast.

    Maybe it's just me

    Reading through the original post and the responses I get the feeling that there is some considerable lag in performance of the mark? I certainly do not notice a hesitation in my D4 3.0L vehicle......that said, I have been driving it since 2011 and on occasions I do not spare the horses so to speak. Maybe I am so familiar with the vehicle I don't notice any hesitation? Mind you I did come over to the D4 from a D2 and there was certainly hesitation / turbo lag in the D2! Personally I reckon getting a good independent LR expert to 'have a look' would be well worth the money.

    Drove the car to town

    Hi all
    I totally agree with theres no replacement for displacement. And totally don't expect the car to behave in the same manner power wise to the landcrusier but when a car in the 21st century, does not pull away when you apply the accelerator there definitely something wrong. We live in a rural area about 60 kms to town, today we drove the car, coming out of the driveway rolling on the brakes as its on an incline, foot off the brake, went to accelerate slowly onto the main road and dead, no momentum at all just like the car stalled, pulled my foot off the accelerator and stabbed the throttle way we go. I didn't notice black smoke from the rear of the car, I gave it some salt & pepper to town, and honestly never noticed it driving around town. we booked the vehicle in at land rover in newcastle to give it the once over and if continues ill mention it when i drop the car off.

    Thanks for everyones input much appreciated.





    regards

    Start with a full service for sure. Air cleaner, fuel filter etc.

    I remember a Top Gear episode where they got a big performance gain just in servicing it.

    There is of course that occasional problem with a faulty brake light switch which can throw it into neutral when stationary and nothing there when you take your foot off the brake and accelerating for a moment or two. I had that problem earlier this year on my D4 and the knowledgeable fellas on this forum told me to replace the stop light switch (about $30) which i did and haven't had the problem re-occur.

    I agree with you that it's not great and this situation is its achilles heal. I've had similar to this from new (2014, 8 speed); coasting and then accelerating often needs paddle shift intervention. Keeping it in Sport helps.
    It will only be partially improved by spirited driving, which you won't have done enough of yet for it to relearn shifting pattern.

    I think what you've described so far is unlikely to be a problem such as brake light switch.

    Cheers,

    I assume that the 3.0 is the same as the 2.7 but regular cleaning of the MAP sensor certainly helps performance. As does making sure the MAF is working - mine wasn't when I bought it and putting in a working one did improve performance.
