Are there any 4 cyl diesels out there that don't sound like tractors at idle?

I am currently in the market for a new company car in the £20-£24,000 ish range.

I have always loved petrol engines, but today we were *really* impressed by the Jag X-Type 2.2d. An excellent car and a seriously impressive engine.

But...

We both had a real problem with the noise it makes at idle. In fact I nearly cancelled the test drive when the salesman first switched on (glad I didn't).

My wife is a professional musician with very sensitive ears (she can hear dog whistles and if I'm eating on the phone can sometimes tell what's in my mouth!) Hence these things matter a lot to her - they also matter to me.

Obviously we can choose a petrol car instead, but the diesel has big Company Car tax advantages and we both really enjoted the torque.

Peter

PS I know the car is lovely and quiet on the M-Way, but we live in North London, so lots of queuing, traffic lights etc.

As regular BRers will know I won't buy anything (petrol or diesel) with anything less than five cylinders for exactly the reason of cultured refinement, but sticking with the four cylinder diesel brief; the current Accord diesel has so far impressed me the most for absence of external and internal clatter.

I've driven most of the commonly available mid sized saloons at one time or another as hire cars, both petrol and diesel. The only 4 cylinder diesels that for me stood out for their refinement were the Renault Laguna, Peugeot 407 and BMW 320d. Of those, the quietest was the Renault Laguna which is one of the very few models where I really couldn't tell it was a diesel engine. I say this as someone who is not a big diesel fan and, previously, detested Renaults. The others, in my opinion, range from noisy at low speeds (Ford, Vauxhall, Mercedes) to agricultural (VW).

We have 3 Citroen HDis in the family - I wouldn't say any of them "clattered" at start up. But then I used to have XUD engined cars!! Doesn't the new Jag also have the 2.7 engine - joint PSA/Ford development? Isn't that v quiet??

Yes, but the 2.7 is 6 cylinder so with his stated brief of four cylinder models he tried the 2.2.

Accord diesel is supposed to be quiet. You could wait for Lexus to launch their new IS diesel. Not sure if it's a 4 banger?

I test drove the Accord diesel last year and was V impressed with its quietness, smoothness & power but I just couldn't bring myself to spend that amount of money on a car so I plumped fpr the one that was almost as quiet and refined - No laughing now- The Primera 2.2 dCi - 30 K later and I'm impressed.

Those of you to whom badge snobbery is important can stop laughing now. I usually titter at you each time I look at my bank account!
Any quiet 4 cyl diesels? - Roly93
There are plenty of quiet 4 cyl diesels to be had now !
The new BMW 2 litre unit is astonishingly quiet at idle, the 1.9 fiat unit in the vauxhalls and new Saabs is pretty good, as is the Jag/Mondeo I think.

I think you have to be realistic, in that it will probably nevere be practical to make a diesel engine as quiet as the quietest petrol engine by its very nature, but I think almost all of the car companies have done a splendid job so far, compared to diesels of 5 or more years ago.
Any quiet 4 cyl diesels? - Roly93
Further to my last post, bear in mind also, that brand new diesel engines ofetn take a few thousand miles to 'mellow-down' and get quieter anyway, if you are looking at new cars.
Any quiet 4 cyl diesels? - bazza
A number of diesels in our quiet close out in the sticks. In the early morning:

BMW 3 series diesel almost new - astonishingly smooth and quiet

Mondeo TDci 2years old - definitely a diesel, lot of clatter and whining - worryingly so!

Octavia tdi - ditto without the whining

Peugeot 307 hdi - smoother than tdi, not as quiet as BMW

Kia Sedona - awful

Land Rover Disco - even worse, often mistaken for a delivery van

The BMW takes it!

Any quiet 4 cyl diesels? - montpellier
ran the Mondeo 130 Tdci for 2 years and 120.000 Km's. very noisy on accelaration and idle. One of the reasons I got rid of it. very good fuel MPG (over 50!) However, not too bad at motorway speeds. Now driving Volvo V70 D5 185 Bhp which is especially quite in town and actually sounds great when you put the foot down. Silence around the 55..65 mph zone and 2.000 Rpm. I did try a Jaguar X-Type with same Mondeo Tdci engine and it's not the same noise levels at all. Very very good car and also tried the S-Type 2.7 Diesel- just amazing but was way over my budget. Maybe try to get a late used BMW 320d or even better 330d or Volvo D5 for the refinement.
Any quiet 4 cyl diesels? - mss1tw
Just to add my 2p worth...

51 plate 306 2.0 HDi.

Running on premium diesel.

Startup, reasonably loud, but not clattery. I like diesels though so not a problem for me.

When it's warm, it's suprisingly quiet, especially on posh diesel.
Any quiet 4 cyl diesels? - bbroomlea{P}
BMW 320 mentioned alot as being smooth and quiet, whilst I have a Rover 75 diesel, its the same engine and can confirm that if it wasnt filled with the black nossle then you wouldnt know it was diesel. No extra noise whilst cold, no smoke and no clattering and rattling at all throughout the rev range. Compare it to my dad's 2002 Audi A4 TDi and his is like a tractor!

IMO a great engine - BTW mine has done 215,000 miles and it is still as quiet as a delivery mileage 75 I test drove 6 months ago!

Any quiet 4 cyl diesels? - cheddar
The X-Type Mondeo is one of the quietest 4cyl diesels from a cold start, and gets quieter when warm, though will improve over the first few 1000 miles, my TDCi 130 has now done nearly 100k miles and puts a neighbours year old 2.0 TDi Golf into shame, also the TDCi's idle very smoothly when for instance in traffic, a very petrol like idle, the only near competitor in this regard that I have come across is the Renault 1.9 Dci.

Perhaps the 2.0 d X-Type will be slightly quieter that the 2.2, and will still provide stonking performance.

I would be quite happy to do another 100k with a TDCi 2.0 or 2.2 in either an X-Type or Mondeo, i.e. I dont reckon you will go wrong with a 2.2 d Jag.
Any quiet 4 cyl diesels? - Altea Ego
The Renault 1.9DcI is very smooth and clatter free when cold. Little difference between cold and hot.

This engine is a gem, it makes a unique sound when pushed hard, kind of a growl, not petrol or diesel like and rather pleasant and satifying.

The best part is, for its size it manages to spread the torque quite widely in its rev band, not at all on/off like most other tend to be

I had a few months of hell in a 163 bhp (more like 16.3 bhp) V70 D5 (2005 MY) and it was unbelievably clattery and noisy, espcially at m/way speeds.

I have been using a new 150 bhp SAAB 9-3 Wagon and it is a very spirited enginebut still pretty rough round the edges, especially when cold.

V6 VAG diesel is pretty refined and the 6 pot BMW too.

As has been often posted by many other BRers BC, it seems that yours was a poor example that had probably been trashed before you took second hand ownership; every D5 S60/V70/S80 I and most others have driven, has been reported as svelte, swift, and refined. Match it with the smooth shifting auto box (says me as a confirmed manual man, but in this case it is true) and the whole thing makes even more sense.

My advice is to learn to live with the diesel clatter. It masks those other annoying sounds you get in petrol cars like whining gears or rasping exhaust note!

For 99.9% of the time I drive round with the radio on so never notice the sound of the 2.0TDi motor in my A3 when it's idling. On start up it rattles (especially when it's -3 degress like this weekend!), but this soon goes. At motorway speeds I get more road than engine noise. This engine is much quieter than the 1.9 version (I had a new A4 courtesy car with the 1.9 and it was noisier than the 2.0TDi).

I'm interested to hear you say this as I dont think my 1.9 Audi is too bad, but I am going to buy the 2 litre when I change in a years time.

I used to have a SaaB 2.2 Tid which I sold more or less purely because it was so noisy from a diesel clatter perspective. In fact even after 20K+ miles, it was an emarassment to me unless it was 'motorway hot', the VaG 1.9 engine by comparison has clatter but is is very muffled compared to the very 'sharp' clatter of the Saab.
Funnily enough, I dont find my engine any noisier/quieter whether it is hot or cold.
Any quiet 4 cyl diesels? - Malcolm_L
I've enjoyed 26k so far in an Accord diesel, quiet enough that some passengers query whether it's a diesel.
Fuel consumption isn't as good as the BMW/VAG units (it really doesn't like 80+ or heavy traffic).
However, it's well put together, handles well and pulls like a train.

Dad has a 320 diesel tourer which nicer to drive but is definitely noisier which surprised me.

I've got the 120d (engine also in the new 3 and 5) - which when on the move is very very quiet, but on the cold mornings it is a bit clattery.
But I've got to say that for probably 5 to 10 secs per journey it really is a small price to pay v the BiK benefits and lack of noise for the rest of your journey, along with the usual TD benefits !

I'm no great fan of diesels but the VAG 1.9 in my mate's Ibiza is amazingly quiet. For about a minute this morning was the loudest I've ever heard it because it was so cold. Then back to the normal quietness.

With this thread in mind I drove home yesterday with various amounts of background noise! Radio on - engine couldn't be heard on idle. Radio off and climate on auto at 23 degrees, fan could be heard (it was on half power) engine couldn't, turned fan off and there was a real diesel clatter in the cabin as I sat at a set of light. Looked in the mirror and 6 inches from my bumper was a 10 year old diesel Transit van (!!) - van had gone by next set and with everyhting off engine could just be heard, but it certainly isn't intrusive.

I have a Renault Laguna 1.9TDCi as a courtesy car at the moment, and I usually drive a Skoda Superb 1.9TDI. The Laguna is far quieter and the powerband is far wider, and it even seems to like revving. I am very impressed. However, the interior is a bit cheap-feeling compared to my Skoda... but I do like the dashboard mounted handbrake! Overall, v impressed.. if I didn't work for VW Group I'd certainly think about one.

Does it have to be 4 cylinders? I'm with SjB on the 5 cylinders or more front - it really does make a difference (5 cylinder Discoveries notwithstanding!)

All in-line 4-pot engines are less than perfectly balanced, requiring either a balancer shaft or opposing cylinders to correct the deficiency. Does anyone outside the aircraft industry make a boxer diesel?
Any quiet 4 cyl diesels? - L'escargot
Yes yes yes!

But are there any diesels that equal a petrol with regard to heater warm-up time? The last diesel I test drove was a 1.8 Citroen ZX and the heater warm-up time was atrocious. It seems obvious to me that if you get more mpg then there will be less fuel being burnt to heat up the cooling water.

Spot on. Quite normal for a diesel engined car to take longer to heat up. As you say, it's burning less fuel and the heat is efficiency loss.

I don't think you ever drove a ZX with a 1.8 diesel engine. The only diesels ever fitted to the ZX were the 1.9 D and 1.9 TD.

Actually, the 1.9 TD in our Xantia warms up very quickly. The HDI is slower to warm up.

I stand corrected ~ it was a 1.9D. Like everything else, as you get older your memory doesn't work as good as it used to! I ran the assessment according to FMVSS 105 for windscreen defrosting (which is at idling) as per what car manufacturers do for the US market, except that the ambient temperature was about -5 degC instead of -40 degC. (Just a bit of useless information!)

I take my point back. Channel4's latest road test of the IS220d is as follows:

"So while the IS diesel could afford to lose a little to the competition in terms of performance or even fuel economy, the one thing we'd all expect is that this would be the outright class leader when it comes to refinement.


The engine lets you know that it is a diesel
It isn't. Under ideal conditions - ie light throttle at a motorway cruise in top gear - it's fine, standing comparison with competitors while not necessarily besting them. But under load while accelerating from stop or negotiating a steep incline, this engine lets you know it's a diesel, with a booming roar and a little vibration through the pedals. Gently driven, it's not bad. But that's not the point - this is a Lexus and it should be head and shoulders above the competition."

Any quiet 4 cyl diesels? - peterb
Thanks everyone for comments and suggestions.

Our thinking is to get a petrol engine as I'd rather pay more tax on a car I like than less on one I don't. I'd kind of hoped the IS220d would have been refined, but the C4 review confirms what I'd heard elsewhere.

The point on multi-cylinder is well made. I'be been spoiled by the smooth straight six in my IS200. So, where we've got to is:

Volvo S40 2.4/5 cyl SE - great engine, best equipment (leather etc) and excellent handling. Currently in pole position.

Audi A4 - great car but very firm ride and engine sounds rather boomy. However we've only driven the 1.8T and we'd want a 2.0T

X Type 2.2d - see first post above!

BMW 320i - rejected due to low rent interior, sparse equipment (rear arm rest is extra cost option!) and lousy dealer attitude

Honda Accord - too large

Still to try are the Subaru Legacy 2.0 and Saab 9-3 2.0t.

Will let the BR know what we decide.

Peter,

Is there any reason why you're discounting the S60?
Any quiet 4 cyl diesels? - montpellier
I've just done 9K in a V70 D5 185....pure magic. Just love the growl and 6.8L/100 average fuel economy. Almost 600 miles on a tank! I guess a S60 would be alot cheaper to buy and give even better fuel economy? For me the diesel experience is a european one and should stay that way. Honda,Nissan and Toyota have jumped on the Turbo Diesel band-'wagen' and deserve our attention but, they've missed the boat when it comes to 5,6 and 8 cylinder diesels. Ok...Renault use an Izuzu sourced 6 Pot but that's about it.
Any quiet 4 cyl diesels? - peterb
I tried the S60 4 years ago when I got the Lexus.

It's a fine car, although a little larger than we want. Also it now seems very slightly dated next to the S40 and IIRC doesn't handle quite as well.
Any quiet 4 cyl diesels? - cheddar
I agree with the S40 5 cyl, likely to be a great car. However the Lexus IS220d C4 tested will have been brand new so as per the X-Type 2.2d you drove is probably 10000 miles from it's best.
Any quiet 4 cyl diesels? - peterb
It takes me 12-14 months to do 10k miles. I can't wait that long...

Also, the X-Type demo *wasn't* brand new. I didn't check the mileage but the salesman mentioned that they were replacing it soon so it must have done a few thou.
Any quiet 4 cyl diesels? - SjB {P}
Well, nice to see that we've moved on from four cylinder diesels! ;-)

S40 v S60 it depends what you want;

The Volvo five pots in all guises are fine engines (of the current range D5 185 and 2.5T are my favourites from experience), but to compare S40 and S60 for a moment:

The new S40 indeed has the edge in the handling dynamics; an excellent car that truly surprised me when I had a Hertz S40 2.4i rental in Sweden for a week. Riding on 16" rims with squidgy high profile tyres it still managed to have electric turn-in, high grip, lots of feel, and a wonderfully compliant ride. I could almost have been in my wife's 306 Sedan that I use as the benchmark! The S60 in comparison has huge grip, but is a little inert on turn in and is less compliant in all suspension/wheel size combinations. Even the 2004 steering revisions don't turn these characteristics in to class leading. Where the S60 scores however is the absence of road noise; in the new S40 and V50 this is more intrusive whereas the S60 is a wonderful, refined, express. The S40 was also quite nervous in a (strong and gusting) motorway crosswind.

Surprisingly, I found the new S40 (and V50) to be more spacious for back seat passengers than the S60 (which to me is still the world's best looking four door saloon by a country mile). Headroom in the S60 is restricted (I'm 5' 10" and my head pushes in to the roof) as is toe room for the centre passenger, and knee room. The S40/V50 have thinner, countoured, seats that help alleviate the latter and seem to avoid the toe room problem and have more head room.

The dashboard in both are paragons of excellence, so it comes down to style preferences. I love the wonderful floating console in the S40, but prefer the "big car" look and feel of the S60 dash. Note that the new S80 (Eighty) gets the floating dash, and from the spy photos it is very well done.

For NVH (Noise, vibration, and harshness), the S60 is the better bet. Not only less dominant road noise as already described, but much better engine isolation too. When starting the S40 from stone cold - especially with the automated high initial revs to help reduce emissions - in relative terms it felt intrusive. In driving too, at all speeds and throttle openings the engine was not as suppressed as in the S60. Of course though the five pot warble is still the cultured and pleasant sound that it always is. No four cylinder "boom" here.

When it comes to performance, I will admit to being a little disappointed by the S40 2.4i. I expected a rocket ship but didn't get one; it was far from slow, and overtaking was easy, but it never really seemed to "get going" and pin my head to the head rest like I would expect of a 2.4 litre engine in a small saloon. Sure, I'm spoiled by a tuned V70 2.4T with 254bhp/444NM torque, but on paper it has more power than the old turbocharged S40 2.0T so should have gone similarly well; without the torque though it isn't the grin inducing swift car that the latter was (my favourite of all variants, including T4, for the previous range). With variable cam timing and stacks of electronics to help, the power band was impressively wide and the engine nice and flexible but it was consequently flat in delivery; engine speed, rate of acceleration, and noise all seemed to increase at the same linear rate. No nice "whoooooooo here we go" that's typical of four valve engines starting to breathe properly (or my turbo boost curve going ballistic at 1800RPM!)

So, conclusions from my week? A smashing car that was great fun to drive, becoming a hoot to do so on Sweden's usually empty A and B roads; the handling composure and ride was that good. This base model was quite well equipped (though no concert hall sound system a la S60), and completely painless to live with. The S40 has smashing good looks and a well well planned interior, though my early model had a couple of small build issues that surprised me (rear window upper seal worked loose and came down stuck to the window and the rear light cluster contour did not exactly follow the body "shoulder"). Did I enjoy its company? Yes, very much so. Would I buy one? Love the looks, love the ride, love the handling, was surprised by the interior space, but I'd wait until I'd tried the T5 (that is also shared with the new Focus RS).

Any quiet 4 cyl diesels? - nutty_nissan
I am surprised that Lexus would launch a diesel engine which is not refined. The fact that most of their bigger engines are the quietest on the planet, and they took ages to develop a quiet diesel, should lead to a very quiet diesel.

Perhaps Cheddar is right and you'd have to drive a new car which has done a 1000 miles or so for the engine to loosen up?
Any quiet 4 cyl diesels? - Happy Blue!
Two things: -

1. If the Accord and S60 are too big, so will the Subaru Legacy be.

2. If you are only doing 5k-10k miles per annum a diesel is a waste of money. You are far better off getting a larger discount on the petrol model you want.

Lets say in any of the cars you are looking at you do 8,000miles pa. In diesel at 40mpg or petrol at 22mpg. Fuel is 88ppl (£4ppg) petrol and 93ppl (£4.23) diesel.

Diesel will cost you £846pa and petrol £1455pa. A diesel saving of £608. But servicing will cost about £150pa more and the petrol will cost at least £1,500 less to buy with discount.

I'll go with the Subaru......

The reason for going diesel would have been lower company car tax (based on carbon emissions and therefore similar to fuel economy).

The S40 T5 sounds great but would cost a bit more than I want to spend. If I was going to do that, I'd get an IS250.

It is the Focus ST, re the 5 cyl turbo, although similar bhp/nm figures it is tuned for more midrange punch in the Focus and is apparently more vocal with a charaterful sound track where as it is supposed to be more muted in the T5.

"I wonder why tickover noise should be more important than noise when travelling?"

That's a good question - I've been pondering why this bothers us so much. All I could come up with were:

2. it just does! - we are both quite sensitive to noise (perhaps because we have no kids?) and when I hear that clatter-clatter-clatter it does something really unpleasant to my psyche!

Unless you spend a lot of time standing on the pavement listening to the engine when cold, I'd be surprised if you described the better diesels as clattering. More like muttering.... BTW, have you driven any yet?

I must say that the Mondeo Tdci I'm hiring is pretty quiet for a diesel. I am impressed!

However, it's winter time so the windows are all closed, different driving experience in the summer.

I put the window down the other day as I was parking up, and the clatter was loud as I was pressing the gas pedal. The insulation must be pretty decent then.

Any quiet 4 cyl diesels? - cheddar
If the Ford / Jag diesel is two noisy on idle then no 4cyl diesel will do, if the S60 is too big a 6cyl 330d might be worthy though it has an urgent feel on idle, yes 6 cyl refinement though with that urgent diesel 'hunting' feeling on idle where as IMO the TDCi and DCi's idle in a more relaxed petrol like way. Jag S-type 2.7d, that would fit the bill though is it 1/ too expensive and 2/ too big?

As has been said for 10k miles a year a petrol is probably the best bet and for £20 - 25k or so there is a great choice of petrol sound tracks.

That's where we've got to. I suspect the 5 cyl 2.4 Volvo will win out. I agree with whoever said that it's not a rocket ship, but it has more low down pull than the Lexus so I'm pretty happy with that.
