DPF removal? Better think again!

[Paul-R]

Matter of opinion. I think that petrol engines are nasty revvy little things with no low down pull.

My Xanita V6 would beg to differ. Loads of low down pull right down to about 1400rpm. In fact the gearbox tends to change up a gear to bring you down from 2200 to 1500 or so under normal around town driving conditions.

It may have plenty of torque but we're up against the heavy fuel consumption problem again. An auto gearbox skews the results as well as I drive manuals by preference.

On a petrol V6 you get diesel like low down torque and high revving (6500rpm) high horse power output at the top end.

It might not be little but it's still nasty revving.

0-60mph is a pointless figure, which is why manufactures like it and try and convince the public (well done German marketing) of the need for it.
Zero-60mph has ZERO relevance to everyday driving or a cars true performance. As Clack-on-son said....40-90mph and 60-Zero are better figures to asses a cars capability.
For those we have only Magazine tests....and people don't believe them when they want to.

I wouldn't say its pointless. It still gives a rough indication of the acceleration potential of a car. A car that can do it in 7 seconds is in a different category to one that can do it in 12 seconds...

I would say top speed figures are completely pointless, as any modern car even those the size of a large shopping trolley can do over 100mph these days. But if it takes you 60 seconds to get there what's the point.

I agree that 40-90, 30-50, 40-70 and so on are all more useful for real world driving conditions than 0-60, and that's where a car with a wide power band and flat torque curve like the Xantia V6 does better than its 0-60 time suggests, but again, if the figures are not available how can we do a comparison ? And who decides which range to use ?

What are the Citroen's with the best acceleration from the factory, whatever acceleration metric you use to measure it ?

I certainly don't dispute fuel consumption. It's not designed to be a shopping trolley that's for sure, but on long motorway trips its actually pretty decent, and no worse than my 2 litre petrol Xantia was.

Petrol V6's are available in manuals... just ask David H or Stickyfinger. This exact engine was available with a manual gearbox in the 406 Coupe, but sadly never in a RHD Citroen. I have only ever been a passenger, never driven the manual version of the V6 Xantia.

Have you driven a Xantia V6 ? At lower RPM the engine is almost inaudible in the drivers seat over the noise of the air con fan on low... at higher rpm it has a wonderful sweet song and is not particularly loud even then. I'd hardly call it nasty!

There is a big difference in engine song and smoothness between a 4 cylinder petrol and a V6. Personally the sound of the engine when revved is one of the things I like most about the car.

Boy - has this thread veered off again!

I give up!
We may as well throw in the size of Wagon Wheels or that as OXO cubes are now made in the shape of an 'X' you now get 2/8ths less stock.

It's all trivial really, 60- 0 is important but no good if you can't steer at the same time. 0-60, not important to me but that first 0-25 is because thats the bit I use to pull out. Probably the same everywhere but up here people will speed up and move towards you in an effort to stop you pulling out, that first 25mph is really important. Most refuse to move out for people on slip roads as well, which are short here, so having a bit of mid range poke is really good, does 40-90 explain that? Well I've rarely seen a flat slip road. I'm usually loaded up as well so the figures loaded, which are never stated, are important.

My favourite way to decide, drive it and see how it goes. Figures are nonsense if you check them yourself in the real world they vary massively according to wind, load, gradient, tyres, state of service and a multitude of other factors. Oh and anything over 85mph, thats for racing tracks. Police have far too many undercover cars now, you can't move up here without passing one, I don't see why road cars are geared to go any higher than that personally and I am a little speed demon but I like my license.

I was watching rip off Britain just now and they were on about the size of chocolate bars getting smaller therfore hidden price increases [emoji12] [emoji23]

[Paul-R]

Now don't start me on about chocolate...

[Stickyfinger]

and as for "Snickers".....phaffff

Actually - I have got a confession to make, and yes, I am going and . I was on an a Foreign forum a few days ago, discussing automotive Hard drives on a thread, but because the topic went from the actual 'removal'' of the drive unit to a 'suitable' hard drive replacement, the Moderator threw his LDS out of his reservoir, having a right puddy and started warning everyone to pack it in! I basically told him he wouldn't last 30 seconds an a certain other Forum being that Draconian, and that he was welcome to move it! I'm not sure how that came out in translation, but that was toooo strict.

Having said that though, I can see in the calm light of day that they have all their topics very strictly listed in subject - but it does make it easier to locate information, without having to resort to using the search facility very often.
So I think there is a bit of a balance between having a good old free for all - which is best reserved for the general chat threads, and subject relavent stuff, that should TRY to remain near to topic as far as poss. I'm just thinking if anyone tried to find any relevant info in this topic, they'd have to get past the 60%+ of other matter Rant Over, kettle on.

My 406 V6 coupe with the manual box was an absolute gorgeous thing to drive with the V6 and not at all nasty or revvy. 24 mpg around town possibly a tad more if careful , would I choose this over a turbo diesel , you bet I would as much as I like diesels . The modern Dpf equiped diesels don't suit my low mileage commute so not for me . My Freelander 2 doesn't have one fitted .

That's the kind of consumption that would just cripple me. I really can't justify it.

Yes, it's a great shame. I know that DPF design has moved on since the early days but I really wonder if there's anywhere on the Isle of Wight (to pick a place) to get a car up to a high enough speed to burn off the particulates.

[bxzx16v]

I'm lucky I don't do much mileage but mid 20's was bearable and worth it for the engine note . I used to run 1.9td xantias which wouldn't do much more than low 30's and a 2.2hdi C5 which only just bettered the V6 . The best all round vehicle was a Laguna 3 with the 2.0 175bhp diesel which had fantastic in gear performance , this didn't give any trouble Dpf wise in the two years we had it , a very underrated diesel engine the Renault/Nissan .

I got an indicated 90 out of a twin pot Visa on the downs road on the IOW.... short lived though, as it soon slowed down trying to get back up the other side! It only takes 5 or 10 miles to re-gen the filter, and there are plenty of roads there for a good blast (*). In and around towns where they never got warm is where the troubles lie.

Consumption isn't the be - all and end - all though. I paid £500 for a V6 car some years ago that didn't do much more than 26mpg any time. I ran it for a year and 13,000 miles, which worked out at about £2100 in fuel at the time.

Considering I could have 5 grand on a car that did 30% more mpg, I'd still be quids in. Many people make the mistake of ignoring the purchase cost of a car when calculating costs!
