    and add the restricted air flow through the radiator/intercooler to that so bad for the cooling too and the higher the ECT is the more you must push the throttle for the same power... IMO any kind of bar in front of the grill especially if some big spots are fitted to it is just a useless triffle

    Thanks. One man's 'triffle' is another man's bacon and eggs. :D But for most purposes I would agree, including on my truck. I love the front end as she is!

    Copied from the DVLA site..

    It is not illegal for vehicles to be fitted with bull bars, although the department would not recommend their fitment unless it has been shown, through compliance with specified safety standards, that they do not pose an additional risk of injury to pedestrians or other vulnerable road users.

    There are no plans for legislation to require bull bars that are already fitted to be removed. However, since 25 May 2007, it has been an offence for bull bars that have not been approved as compliant with those safety standards to be sold. Approved devices will carry an indelible ‘e’ mark (for example: e1 01 1471).

    Thanks. Ha ha, the usual guff. Guidelines, recommendations, not a word of "it's illegal to have them", but they sent around the usual mysterious impression and led people to cite such bunk. It's much like the firearms act and how the police 'spin' it to suit their Chief's unlawful laying down the of law without Royal Assent. I do get a chuckle out of how they get their way with so many people by blinding them with cleverly constructed sentences backed by the 'authority' of an organisation like the DVLA which sells personal data for £2 to any unscrupulous ex-clamping scum bag with an 'SIA' badge (or not). :D

    Big lumps of metal weigh a lot.
    As I know having recently taken my tow bar off. Dragging this around all the time bound to add to fuel consumption although I have to agree with @sierrafery about airflow around the front.

    No dear, this kit on the front of my disco had been there since it left the showroom so that 22years + and without any issues, or hindering in servicing of the engine or vehicle performance on the road. :D

    For example with that abomination in front of the rad more than half of the air flow is restricted

    Do we compare Td5s with other kind of engines again ? V8s or Tdis are a different story

    I watched live data on a friend's Td5 with and without such bar with spots fitted and the difference was up to 15*C which means around 90*C without and 105 with it same day

    Comparing engines and the perceived air is of topic for this threads title.
    But I would say in my experience of petrol engine vehicles is... don’t worry if you u have an ‘A’ fitted :D

    That's nice. I imagine that would protect your rad in some circumstances like a shunt on the M25. Do you think so, or is just a vanity thing? (and it does look pretty I must say :D)

    I had a minor shunt int the fender which had a A bar (numpty site manager reversed into me), probbably made it worse. When my bull bars got ripped off they took the indicator cluster with it. I would expect no protection from crashes with bull bars, and possibly increased damage.

    Thanks, although I am not so worried about general damage, just the radiator/engine

    I don't think it is illegal to fit them but to sell them or for them to be factory fitted by the vehicle manufacturer they have to be EU compliant from 2007.

    2007, I was wrong about the 1997 cut off date.
    The only vehicle I have had them on was made in 1989, so I didn't really have to worry about it.
    I thought they were a waste of space, wouldn't get them again.

    Depending on the size of bump an ‘A’ bar it may prevent damage to the radiator but it could put a dent in the leading edge of the bonnet and slam panel below.
    There’s already a bit of space from the front of a disco before reaching the radiator, so it should be still safe in a bump anyway, but because of an ‘A’ bar being fitted theres now damage to the bonnet which may have escaped, leaving damage only at the front bumper if the bar wasn’t there.
    Assessing vehicle accident damage isn’t my field but that’s my take on A & bull bars.

    The only thing I had attached to the front of my RR was lamp guards, but back then bull bars of the wrap around verity were a popular fitment, also popular was a twisted bull bar pushed in deep dent on the wing, and no other damage... but they did increase the width of the RR.

    Also on sale was a bar for the rear of the RR a drop item a bit similar to a bull bar , I never saw one fitted or the after effects of a rear end bump. :(

    As for “vanity” only a vain owner can answer that, I’m far from being vain so I don’t have an answer to your question :D

    If I was in a shunt on the M25, I think the radiator would be the last thing I would be worrying about.
    I would be thinking more about the driver in the 38 tonne artic behind, wondering if he was asleep at the wheel, or on his phone, or if he would be alert enough to get on the brakes before he crushed my vehicle on the tarmac like a squashed fly.

    Chap I know likened them to crash bars popular on older motorcycles. If they are strong enough to withstand an impact they're likely to transmit that energy into somewhere else and twist the frame or chassis. If they are not then they are likely to bend and spread damage over a wider area.
    You pay your money and you take your choice.
