£750 Citroen C6 1200-mile test! 2.7 twin-turbo diesel. But what's it like?

After more than 1000 miles in a £750 Citroen C6, did I like it? ‪@UPnDOWN‬ carried out a fair amount of work before this test, so head to his channel to see what he did, and batter the Subscribe button very hard. Yes.

Saw this pop up on my feed for some reason, and rewatched it. Over a year on, I thought I'd update on some of the issues, for anyone interested. * The suspension is working fine here. That's just how they are. It's not 'bouncy' as such, it's just trying to compensate every little bump/undulation, which ends up in a worse situation on our awful roads than it would have otherwise. We took it to France not long after this, and it was transformed (because they know how to lay roads!) It's possible the centre spheres might possibly be a teeny bit low on gas, but it's not by much. Have since driven tidier, lower miles C6s which ride worse! Ian is correct in that it's underwhelming, though; It's very smooth compared with other cars of the same age, but compared with older Citroens it's not the amazing experience people make it out to be. It is very impressive in the corners, though, given the size/weight/softness. * The gearbox is actually working fine, too. The issue actually seems to be the torque converter permenantly locking as soon as the gearbox oil heats up up, which is why it's so horrendously laggy pulling away and when pushing it in lower gears. It's effectively trying to accelerate from idle with no slip whatsoever. How it doesn't stall the engine more, I've no idea! * The A/C now works, and it's brilliant. * It wasn't running at full power; the DPF was semi-blocked. * The steering controls were a dodgy connection, which affected cruise and speed limiter. Again, all fine now. 🙂

Cheers for the update!

I believe these Aisin gearboxes do this when they detect the fluid has been overheated too many times. My Volvo S60 with the TF-80SC went into such a mode when the fluid was in poor condition. Mine has 125,000 miles and I don't think the transmission will ever be perfect, but I do think some more fluid changes might help extend its life. Upshifts are mostly fine, but it seems to struggle downshifting at low speeds as this C6 does. It also has similar trouble going between neutral and 1st when stopping and starting in Drive as well. If the fluid was changed and the adaptives were reset, perhaps it would come back a bit.

Watching from the USA, I’ve only been able to experience the C6 (and pretty much any other Citroen) via photos and videos such as this one. But I’ve found them strikingly attractive, and mechanically intriguing in the same mold as the DS, SM, etc. I love how Citroen could start with a clean sheet and seemingly disregard how everybody else was doing it, in favor of creating something unique and beautiful, even if quirky and flawed. So thanks very much for this episode! I enjoyed the chance to become acquainted with this C6.

[@give_me_my_nick_back]

The problem is they never got a premium status so you would always compare them with likes of golf, passat, fiesta, mondeo rather than Audi or BMW so with all their extra equipment people still expected them to be reasonably cheap and that's why it never really worked out. French struggle a lot building any premium brands, peugeot used to be premium but they f..d it up in early 2000s.

I was still delivering cars when these where new, we'd deliver a new C6 to dealers, they'd generally remain unsold and we'd swap them for another one every 6 or 12 months, the dealers didn't want them, 9 times out of 10 the car wouldn't start on collection day because it had stood in the showroom doing nothing and no one even bothered to keep the battery charged, so another pick day would be sheduled.

I have a C6 as a daily driver. 300000 km and minimal problems. As long as service is being done, there is less problems with it than any of all the other cars that I have had. Generally it is not correct that Citroen is more problematic than any other cars. It was true LONG LONG time ago.

[@drummondscar3264]

I had a 2.2 Exclusive at two years old, which I kept for five years. I had two weeks in a friend's 2.7, before this. The 2.7 had a huge lag coming away from rest, which I found was the Aisin gearbox being unable to deal with the torque. 2.2 had no problem, but was rather slower. The box needed a flush out every 10000 miles, not from a Citroen dealer(!), and after 80000 miles seemed like new. Sealed for life, I think not....My 2.2 came from a Citroen dealer, with 18000 miles, and cost me £16000. The only failure was in the wiring, which cost- £25. A really very good car, but I got rid of it because the spares rocketed in price. Oh, and I also have a 1968 DS semi auto, and a 53 Traction Normale.

[@byronmills5952]

Drove a few C6s when they came out as I worked for my local dealership. The impression I got is that it really deserved a bespoke platform -- the size and weight of the C6 really pushed the 407/C5 base chassis to its limits and as a result the driving dynamics were compromised. Ride quality was never classically Citroen Hydropneumatic and I found it to be rather crashy in comparison to my Xantia and Bx. I found the 2.7 V6 Mk2 C5 to be a more comfortable and engaging drive.

[@dafister]

Your comment is spot on. PSA probably knew they had low chance against ze Germans so they didn't bother developing a larger platform. Even the Peugeot 607 was largely based on the 605 as far as I know.

[@bentullett6068]

Ever since I saw one of these cars being tested on Top Gear all those years ago, I have always fancied buying one as a wafty barge. I love the Citroen quirks on this car like the side door pockets, rear window blind, frameless doors, suspension and the nods back to the Citroen DS. Its the modern French electrics that worry me as we had a 2004 Renault Megane Advantage spec estate that was a fantastic family car, was quick, had a fairly posh and interesting interior, but about 5-6 years of ownership we found that the electrics did there typical French thing and stopped working properly. It started with one of the keyless door buttons failing then just like that they all failed and then the boot unlock decided to stop working as well. Also I think my dad was glad to get rid of it due to the mission of changing a headlight bulb task.

[@stiggyness1976]

@@jdtseventyfour The thing is, this gearbox is fitted to quite a few cars including Vauxhall Signums/Vectras with the 2.8 V6 turbo engine. The gearbox is rated for 450nm which is about 330lb of torque, my Vectra is fairly quick off the line considering it's an estate and just takes off after 2k rpm. I reckon the engine isn't producing much low down torque for some reason, Citroen might of mapped it that way, but it's been proven they can take more than 450nm. The big killer of theses gearboxes is heat and coolant, kill both birds with one stone by fitting an external cooler. Even with the temp today 38c I'm having no problems at all with the gear box.

Gearbox is an Aisin Warner unit not ZF - its the TF80SC (known as AM6 in PSA names) . Strongest auto gearbox at the time for front wheel drive, however the engine had to be detuned for it.

The only C6 I've driven was the petrol V6 when the model was new. It is a car that I remember fondly, being one of those cars that could waft effortlessly and yet cover the ground quite quickly. Not in a sporting sense but a feeling of competence that inspired confidence. Yes, I missed the old-school Citroen brakes, but I think it was a fitting final hurrah for the big, oleo-pneumatic Citroen. I can understand why it was unpopular with Citroen dealers, who would rather be knocking out Saxos and the dreadful Xsara Picaasso to people who wanted cheap transport. The comment about laggy pick-up from standstil reminded me of the V6 diesel Volkswagen Phaeton. That was a generally fine car but definitely didn't inspire confidence that you could pull out smartly into fast moving traffic.

[@cameronwood1994]

The crankshaft issue is well known on Discovery 3 and, more commonly, Discovery 4 as they have the larger 3.0 engine. JPSK Motors seem to have identified the problem being poor lubrication to the crankshaft main bearings, with Ford's solution being to use sputter bearings for the top half of the mains. JPSK modify the oilways to 2018-onwards specification and also specify 5W-40 oil (JLR, unlike PSA, specified 5W-30 oil. Ford North America specify 5W-40 when using biodiesel 5-20% - the UK is 7%). 2010-2012 3.0 engines have an incorrectly hardened crankshaft which means they're a ticking time bomb anyway. It doesn't help that the oil change intervals are 15,000 miles on Discovery 3, 16,000 miles on Discovery 4, and 18,000 miles on the Citroen C6 - it is wise on these to change the oil at one quarter of this interval, because these have quite a small oil sump and they also only have four, very narrow main bearings.

Oh wow, my kind of car congrats, if the 3rd gear jerks you have to put a new hydraulic block into it, the Aisin AM6 gearbox (NOT ZF!) was used by several carmakers and is readily available. Had the floating issue too, changed all the spheres no significant change, then the hydraulic pump went out and with the new one all was sorted. About the lag during acceleration, perhaps the airflow sensor is clogged and needs cleaning - sorry got a petrol do not know much about these tractor engines. Got it since early 2017 and it still baffles me all the time, never gets old. Traction control, ABS, sounds like an ABS sensor issue to me.

[@carstenweiland7896]

@@dizzy2020 Did what? Change the pump? Exciting.

[@ricolasroc5890]

The most noticeable lag I ever experienced was in an XM. Given you know those, and you reckon this is awful, that is truly terrifying. I'd like a petrol one to see how it is, but perhaps not one I want to own. LOVE the review though. You are a diamond.

[@euhm]

I always liked this car. When I bought my AX GT, there was a C6 for about the same money. I didn't go for the C6 because of fear for electrical and hydraulic problems. My parents drive a previous gen 508 and that has quite a few problems. So I went for the idiot proof AX GT and have been very happy!

[@rileybenstead3574]

I did have a 3 litre C5 some years ago and loved it, wish I had kept it. I have only ever seen three C6 cars on the road. At one point I was tempted to buy one till I checked the price of road tax and coupled to how complicated they are, thought better of it. I do love the look of them.

[@peterriggall8409]

If you are in the UK can you explain to me why the C6 is so expensive to tax compared with Hubnuts Fairmont. Is it the fact it is a diesel?

[@HubNut]

Vehicle Excuse Duty rates changed from 2001, to start punishing 'dirty' engines. Larger engines mostly.

[@dennisvogelius8602]

@@HubNut The funny thing is that it is really not a dirty engine. Again pencil pushers playing to make life a pain for the rest of us

[@Chillmax]

Re the driving experience you had, I'd bet you pretty much any money, the suspension's faulty from how you describe it, my experience, after changing all the spheres etc, was heavenly, it's nothing like your ride and I would've thought that you'd have said that!

[@HubNut]

I've driven two, the other being the simpler 2.2HDi and neither overly impressed.

[@Chillmax]

@@HubNut They could've all been bad spheres unfortunately, for 2 reasons. The Citroen guff suggests they last the life of the car, rubbish of course & if your do look into changing them, the official cost is horrendous, so it puts people off doing it. It wouldn't at all surprise me that a high proportion of C6's are not running at their best in many departments, so very sad.

Really enjoyed that. I have been lucky enough to be a back seat passenger in one. As you say, there is a sense of occassion. I don’t think I could live with all its foibles though. My pockets are not deep enough to deal with them. Your price of diesel is horrendous! We are complaining about $AU2.50 a litre. About 1 pound 25 p.

My 2015 Focus ST3 diesel with DTUK tuning box- £20 road tax, 220 bhp and 50 mpg. At one time I was a 'who the hell wants an ST diesel' bloke but I am now that person.

[@tallblokesam]

The Discovery and Range-Rover Sport fitted with this engine are extremely laggy in standard tune but respond really well to a well sorted MAP. Nothing mental with mega boost or smoke, just a decent mix of economy with a bit of performance. You actually get a better MPG with the MAP as you're not burying the throttle into the carpet to get it to move. I imagine the C6 would respond very differently with a decent tune. Cool looking thing though, I'm not brave enough to consider owning one..

[@PJ-om2wq]

My Jag X350 with the 2.7 is an absolute flying machine, but then it does have an aluminium body. The Disco and RR Sport had one big turbo whilst the C6 and XJ had twin turbos.

I've never really jelled with the C6, looking at it as an outsider. I'd have a (petrol) V6 XM over a C6 every second of every day. ..i would however suspect that the suspension issues with this one is a matter of spheres that need attention, as mentioned by Kitch himself. I remember the TopGear episode where they tested the C6 as a camera car for a horse race. Suspension seemed pretty competent. ..but who knows. Unlike the CX and the XM, i've never actually been in a C6..sadly. I've been looking forward to this video since we were made clear that you were borrowing it. For the love of Citroens i'm slightly sad it wasn't an undivided succes, but i enjoyed watching anyways.

[@Chillmax]

I don't know what you mean by 'underwhelmed' with the suspension, but I'd say if you did feel that, it's not working correctly. I've owned/ driven all hydro Cits and when working properly, the C6 blows them all away, I describe it as a tank crossed with a hovercraft.

[@ghfdt368]

I remember seeing one of these back in 2008-2009 when i just started college. It got a lot of looks in the car park where people would look at it and couldnt decide if they liked the look of it or not especially when there were C3's and C4's and picasso's about. At the time the C6 sticked out like a sore thumb, But I think time has been really kind to the C6, it looks pretty modern by today's standards and the interior aswell on the most part looks like a car made in the 2010's.

[@Paddy3443]

Dream car ever since my early teenage years ❤️ Looks absolutely amazing if you see it in the wild which was not a common thing even when they were new. Paquebot! Would still love to own one.

I would definitely have one for my lottery win, hangar. Full of crazy cars, it would be with a DS. Best car ever. A CX GTi Turbo. A CX Pallas. An R5 GT Turbo. R16 TX. 1.6 and 1.9 GTI 205s. 106 GTi. 306 GTi-6. And the proper Rallye versions of 106, 205 and 306. That’s the French section. Italian section huge. The British section, Mk1 style E Type with £400k restomod package 😂Great video again sunbeam 😀

[@patrickw6934]

I've been seeing internet ads for the new C6, so they obviously think it worth trying again. However, in pictures they make the new one look even more enormous! I always thought this C6 was giving the inspirational types at Citroen (if there were any left) one last hurrah, but is it just a tribute act!?

[@556johny556]

Would you mind elaborating on those ads you're talking about? Cause I'm curious and can't find anything. Other than the Chinese C6 launched in 2016 which is just a 508 in disguise

Love these Ian ....Still a proper Citroën I feel .. Had a Pug 407 Hdi 2.7 Coupe ... with the same engine ..awesome unit ..torque monster ...really shifted...twin turbo as opposed to the Discos single ... But insanely complicated and no garage would touch it ...lovely lovely car though 👌 😍

[@defender1006]

A friend of mine has a 2.2 C6 without the 'TGV' seats so the rears 'drop down' to make a far bigger load space area, it now has well over 285,000 miles on the clock, yes it's had some issues over the years and some non service parts, but it drives, works and runs nicely and passes it's MOT every year, the last big/proper Citroen, almost certainly, but underestimated and misunderstood, that's for sure?!

[@frglee]

Like the idea of you pushing down the accelerator pedal on a French car, it gives a kind of gallic shrug pause, then proceeds on its way.😁

[@davefrench3608]

My previous C4 with 6 speed electronic auto was also dangerously laggy. My current C4 has a proper auto which gets a bit confused especially when coming up to a roundabout - slow down to check, yes I can go. Hold on says the box, let me find a gear for you, I won’t be long. The C6 is one hell of a lovely car.

[@MrFlazz99]

I think you're half right about the laggy response from a standing start. I used to have a 2007 Renault Clio DCI106 which had the trick variable-vane turbo and could really shift within a certain rev range (the expected narrow diesel band), but it was annoyingly laggy from a standing start UNLESS I booted the revs off tickover before dropping the clutch...so that's what I did. The lower-power versions of the diesel Clio would pick up completely smoothly from tickover, but had rather vanilla acceleration overall. Undoubtedly it was some emissions thing to stop drivers from making terrible smoke under gentle acceleration, but it really COULD make smoke under full-bore acceleration. (I might add that it never failed an MoT emissions test in 13 years of ownership). I loved the engine and the ride comfort (which I took for granted until after I acquired my current 2014 Fiesta which is F*****G AWFUL by comparison, as well as being very cramped in overall cabin space and ergonomically unsuited to drivers taller than 5ft3in), but so many other aspects of that Clio were frustrating in such a Gallic way - the pathetic handbrake mechanism and the stupidly short gearing (caused by attaching a very short final drive to Nissan's brilliant 6-speed gearbox, as also used with larger Renault/Nissan diesels) to name but two. First gear used to be pointless and I'd be into third within two seconds usually. They could easily have lengthened the final drive by 20%.

[@CaptHollister]

Completely agree with you, plush velour is more comfy than leather. I've also never found a use for the shift paddles on my GLK250 Bluetec.

[@peterriggall8409]

I agree too. Most new cars seem to have leather these days……or fake vegan leather, (that may be the new term for vinyl) not much good in hot Australia.

[@grahamariss2111]

I had a similar issue with a Alfa 159 2.4 diesel which was superb other than in 1st an 2nd they had lheavily imited the available torque I guess to protect the gearbox and if you clung onto third too long you were likely to be off boost for what felt like weeks, so you needed to bear this in mind when entering a busy roundabout.

[@benfearnhead9851]

God I love the C6. It's basically the DS of the 00s. I've daydreamed about buying one several times but living in Brum with it's clean air zone I'd want it to be petrol and they're like hens teeth. I actually have a brochure in pretty good nick. Such a sublime piece of car design.
