I’ve had my M340i for nearly 3 years and still love it. I don’t do a lot of miles and happy with 38mpg on a long run. I think if you do a lot of miles, the M340d makes sense. After several diesels in a row, i just fancied a petrol car whilst they are still an option!

[@Csirkefoga]

38 mpg with a 340i?? Wow

[@saltandsham]

[@sandippatel1969]

After 20 years of diesel, I've finally taken the plunge with a M340i. That engine. Wow! I turned the fake noise off but it still sounds mighty. Getting 25 on short runs compared to 35 in my 69 plate 330d xdrive. Using super unleaded as I bought this car with my heart so I could run a petrol 6 pot before they're banned

[@DionWillz123]

I had an m340i as a hire car from work (lucky I know) and had it for 2 weeks. It was a 380 mile round trip and I averaged 43 mpg! And no I wasn’t driving like a granny either😂 Absolutely awesome car and I really did not wanna give it back.

[@iangoff5861]

My last 5 cars have been diesel, and last three BMW. 2 x 420d and now a M440d, thought about going full out for an M4. Truth is I can’t give up the diesel. And yes the combination of the engine and gearbox is a match made in heaven. Any excuse to drive it. Great review.

I'm debating between an M4 and a 340i, think it's going to be the xdrive that win it for me

@@leemacdonald6533 I actually went for an M4 in the end and it’s a competition so it’s an xdrive! So glad I did, the extra width the wheels and the power is incredible! If you can do it! It can still be a bit slippery in the wet I have gone sideways around roundabouts but this could be due to tyres as it’s currently on Pirelli’s! Good luck!

So good that a channel actually does a real-world mpg test, so it's so useful 👍

[@bimmer766]

You should NOT decide between 340i vs 340d based on power, torque and consumption, but based on your driving profile! The 340d needs almost double time to get warm, doesn’t like cold short rides, and due to egr/dpf needs sometimes rpm. It is efficient once warm and likes long higher rpm runs (german autobahn). If you gonna drive 340d in city on a short cold rides or constantly around 1200 rpm without proper motorway run, the engine will be dead before 200k km. I understand, that a first leasing owner doesn’t care, but I just wanted to add few words as a owner of an 2017 f31 330d with 300k+ km.

[@TheCrazyHarpers]

Great review Joe. Always impressive how you squeeze in so much detail and it’s clear you really care about the quality of your videos 👏🏼 Agree with another comment that it would be good to see in gear acceleration too. Real world tests need real world acceleration scenarios 😉

Man I've been wanting to see this comparison since forever and it's like nobody else had done it. Love this!!!!

[@stuartleonard1060]

I live in Germany, and diesel is around 10 to 15 Cent a litre cheaper. 340d makes a lots of sense here. Also, for the fast autobahns the diesel will be a lot cheaper to run.

[@peterhammer6915]

Here in Finland diesel is more expensive than petrol and also diesel car owners will have to pay an extra tax. Owning diesels here makes no sense and they are slowly dying here. Depreciation is massive.

Another fantastic video! You give so much detail without ever getting bored or overwhelmed. I love my 2022 530d touring, its a real shame BMW don't do a M540d. One thing you can't argue with is, the petrol sounds so much nicer.

[@SB_170]

Superb video Joe. Best one you’ve done in ages. Perfect video for me as I have an X3 M40i LCI and always wondered if I’d done the right thing with the i instead of a d. I also have the M seats 😊 and I love it!

[@IMon503]

Really like the m340d. I currently have a f31 335d and it's such a good car everyday.

[@daggidding4478]

Nice comparison, Joe! Always a pleasure watching your videos 😃👍

[@thedrivebygg]

Awesome Joe, just what ive been waiting for. I think you did a great test and a fair test in all scenarios especially the mpg one. I’m a huge fan of how diesel cars pull effortlessly, and my 125D is no exception, but this 340D sounds so good, it would be a really hard choice. My 2014 125D still gets 45mpg on city driving and 50mpg on motorway which really works for me, and does 450 miles on a tank before I fill it up, I’m sure if I ran it dry it would achieve 550.

[@pakmancooper628]

I deliberated for ages over the d or i, but eventually chose the 340i Touring and swapped my X5M50d as mostly a direct swap. The new car is scheduled for next month and in Ermes Verde and thanks for that Joe, you convinced me to go for an individual, individual colour, along with the Msport seats in Cologne and pan roof..........your videos have been a real influence on me, much to the disapproval of the missus though🤣

[@jonclark1091]

I've had my M340i for two years now. I don't do many miles which is why I chose the petrol over the diesel. I commute 2 days a week into London about 25 miles each way. Even in heavy rush hour traffic and queuing for the Blackwall tunnel I can still get 30 mpg over an hours journey and on a good day can get 36. On a rare long trip from Leeds to Kent I managed 47.7 mpg. Not bad for a 3litre petrol.

[@christaylor4946]

My only issue with my F31 335d is that it takes a good 15 mins driving to warm up, so on shorter journeys you aren’t even getting close to the claimed mpg figures. I don’t do the miles I used to post covid and does beg the question about moving away from diesel. But as a car that does everything, it’s superb

[@michaelbuck8804]

Love all of Joe’s videos my only issue with not just these kind of tests but car testing in general is performance is ALWAYS solely measured or at least displayed in 0-60/62 drag races. Which for cars you’re going to drag race (so probably neither of these) is all good. I wish they’d show more kind of real word performance in car videos. In gear speed, overtaking ability. 90% of people who buy cars like this use them on the motorways or back roads and want to know which is more competent for overtaking ‘Sunday Sammy’s’ who are happy cruising at 45 on a 60 road but the road might not have many straights so need to utilise the one chance they might get over the next 2-3 miles of bends. Tests like those for me are part of what define great performance cars.

[@302ci1968]

A long time ago, a French Speaking car magazine used to put, with the oure solo performance figures, an "overtaking" measure: the time necessary to pass a big truck driving at xx mph or km/h and the distance. And it was -not surprisingly- one of the most interesting measure. So, you're right, we need real life performance ;)

[@jamesenglish8639]

Brilliant review , brilliant you tuber / journo whose opinion we can trust . Don’t ever sell out Joe we need honest real reviews like yours 👊🏻 I drove the ix the other week 🤢

[@andrewhurstcars]

Great comparison Joe. The other advantage for high-mileage users for the M340d is having the 30% + extra range, so fewer fill-ups ⛽️. Ultimately it’s down to the owner’s mileage. M340i seems fine you’re doing less than 12,000 miles a year, but I’d want the M340d for more miles than that. Crazy that active cruise control is standard on a Golf, but an option on these 3 series. Should be standard. Edit: August '23 the diesel price has now equalised to petrol, so an even stronger case for the M340d.

[@TsLeng]

Adaptive cruise is standard on a lot of Skodas too.... BMW knows they can get away with charging lol

[@andrewhurstcars]

@@TsLeng yup, same goes for Porsche - optional extra on automatic cars.

[@em4703]

The diesel is also better at highway driving, not just MPG, but in a higher gearbox speed, that extra torque of the engine really makes a difference when accelerating/overtaking another car.

[@boemher15]

Id dispute that in this contest. The kick down on the ZF8 for the B58 and quick spool up for the petrol negates the torque advantage of the diesel. Remember HP x RPM beats NM especially when the ratios are close.

[@Alexdbre]

So I will get maybe a M340i , when budget allows it ofcourse next year or in 2 years (I'm between the C43 and this), like you said the diesel is good for people who drive a lot and the m340i for people who drive less, since I don't even drive 6k Kilometers per year the Petrol sounds like ultimate fun and ofcourse the Toyota Certified Engine in there... Still can't believe the Petrol does 6l and the Diesel 5l , those are big 3l engines with crazy HP! The RS3 with 400hp can't go under 10l , I'll tell you for sure that, so this is eye opening

[@nobotshere8364]

What a man for lending his car 👍

[@where_s_wally]

This comparison review is so good and no doubt really beneficial for anyone making the decision which one to get. It would be an interesting format for any other car parings.

[@thoughtfuldog5424]

Detailed video as always ✅ Would be interesting to see these side by side with in-gear acceleration, rather than a 0-60.

[@00Seven1000]

Excellent video Joe! I was really looking forward to this one and it didn't disappoint. Thanks. I think an additional point to make is that these cars are both performance orientated and owners of these will inevitably drive them at pace. The MPG test driving normally proves a valid point but if you were to drive the same route at pace and having fun, accelerating hard etc, the 340d would be even more impressive and the fuel efficiency percentage difference would be even greater. My take is that 340d is essentially a marketed product for regular autobahn users, so for me, living in the UK, I think I would opt for an M340i.....In Tanzanite blue😃👍

[@alastaircunningham6551]

Loved this. It’s been my genuine question for a year, after I swapped my G31 530d out for something else 😢 Looking forward to the M340d Touring I’ll buy in the next few months and keep it for 20 years + you’re not going to get something that good again (rightly or wrongly)

Very enjoyable as always Joe! Two brilliant cars, and yes, diesel still makes sense !

[@da_great_mogul]

Very, very enjoyable MPG comparison. All I would add is it would be useful to compare the residual values of both petrol and diesel and then backward calculate how many miles you would need to do over the life of ownership to ensure that one engine betters the cost of the other.

Really fantastic video Joe! Full in depth from you with great quality and analysis with your BMW knowledge. Very tough choice between the two and I would perhaps be interested to know residuals and servicing costs over say 3-5 years (typical time people own a car) between the two. That could be the decider as I am with you its impossible to split between the two really. Being a petrol head, I would have the M340i but there is no denying the M340d is extremely capable and has supreme range so it would depend on your usage. The more miles you do each year the more the M340d perhaps makes more sense. Great video and keep up the fantastic work on your channel as always 👍🙂

[@Ryan-oe3mg]

Extra 20p a litre for diesel makes the running costs very similar. 100 miles would cost £14.88 in the diesel and £17.62 for the petrol with the figures you achieved. Problem in the uk is diesel depreciation is massive so I’d imagine you’d need to a significant amount of miles to offset the added servicing and depreciation costs. Still, love a big diesel but also loving my current b58👌🏻

[@PiOfficial]

Doesn’t apply to business users . If you have a fuel card it’s the same price. For example I’m paying 1.24ex vat this week which is 1.48 Inc vat for diesel.

[@BennyStLeger]

Similar price difference between diesel & petrol in Australia, so I would definitely go the petrol option.

[@anthonymeek4248]

And just like that in most places we are back to petrol / diesel price parity.

[@nickbutler7422]

Great video Joe, I decided on the M340i. Not much between the cars but I have had plenty of BMW oil burners in the past (in fact our other car is a 420d) and moved to a M135I a few years back and now to this. I guess if i did high mileage i would of given the M340d more consideration. Cant beat the sound of the B58 and the fun factor of the M340I.

Great review and comparison. I had a couple of diesels over the last few years; a 335D 4 Series GC and a Seat x-perience with the 2 Litre VW diesel. I live in the country and rarely go to towns and my biggest issue with the diesels was MPG on short-ish runs. My route to work is about 10-12 miles depending on which way I went. Country A and B roads with no lights and just a couple of roundabouts. I'd never get more than 30mpg in the Seat going to work and about the same in the 335D. Diesels just take a lot longer to warm up on these short runs. For comparison I now get about the same in my M140i (so long as I don't go silly). Horses for courses!

[@SteveTurner-xv4xy]

I have been running a M340d touring for just over a year ( previously ran the 335d touring for over 4 years ). Never had anything go wrong on the previous car, but the electronics on the M340d have been a little glitchy. One of the exhaust sensors went after 9 months, the head up display has decided not to work occasionally. Most recently the wipers have intermittently decided to turn themselves on when switched off. The car itself is beautiful to drive, like Joe eluded to, it is effortless and very refined returning an average 40.5mpg ( used mostly for shorter journeys ). It doesn't quite have the fun factor of the 335d.

[@olicool11]

Great, comprehensive, informative review with unbiased comparisons. I'm a diesel owner (435d) and I don't believe there is a better engine for power and economy that the BMW 6 cylinder derv units. Mine is slightly modded and gives 0-60 in 3.5 secs yet on a steady run will still still return 50mpg, something I need with a 100+ mile commute every day.

Hi Joe Achilles, Quick suggestion/tip, when you’re filming displays like your phone at 14:40 it flickers.

Really good watch and very interesting comparison. I just bought the Honda Civic Sport Plus petrol as I thought with the price of Diesel being that much more it was the way to go maybe I was wrong. I have though been very impressed with mpg over a 400 mile round trip on mainly motorway and dual carriageway and have registered north of 50 mpg so I am perfectly happy. The power is a bit lacking but I can always jump into the i-Pace we own also and have some spirited driving, without the soundtrack of engine or exhaust of course.

@@markymark1940 I’m probably about the same with an average of 35ish but get the high 40s on a good run. To be fair even when you drive it more spiritedly 😇 I find it rarely goes below 30.

[@bield7]

Good review. I chose the 340i over the diesel as I don’t do much mileage and prefer the i’s sound

[@paulchapman6826]

Great Test 👊 As for which one, for a daily, it's the 340d 👏 Take something else for the weekend, but what 🤔

Jamie's spec goes crazy

Brilliant video! very informative. Something I'd like to see, is the M340i Sedan vs M440i Coupe... I've seen a lot of M340i Sedan vs M440i GC, but there's very little, if any videos comparing the 2 and 4 door B58 3/4 series models, it's something i'm personally deciding between (and a few others online), and i'm really struggling to find any real comparisons.

[@jankohrajko]

I personally think that a huge plus going for M440i GC is the fact that you have a fifth door and thus much more usable boot space. I can see myself stucking a mountain bike into the 440i however the same would be impossible with the 3 series.

[@ian7675]

For my the M340d makes absolute sense as I do a 150 mile commute daily. The cost savings at that mileage really become significant.

[@markhyoutube]

Great comparison! 👍

[@jtwitchett]

I guess I'm pretty lucky as I have the m340d for daily duties but a B58 in a lighter car (m140i) for fun at weekends. For me, the perfect combo 😋

[@Elred77]

Great video, Joe. These real world test runs are really interesting, especially if you’re torn between petrol and diesel. In your opinion, is there much difference between 330d and M340d as a daily? Thanks, and keep the content coming please

I picked up the BMW X3 30e X-drive M-power about 4 months ago as my company car; with the same color combo as Jamie's (Brooklyn Gray with Cognac interior) + pano roof. Damn, I love the car! Great on fuel consumption, as it is a PHEV...charging overnight for my daily commute (about 60km roundtrip). Most of my commute is electric while in hybrid mode...speed limits are 80kmph max to/from along the country roads and max 50kmph while in the city. Petrol is costing me around CHF80 monthly (work commutes + weekend country/city) and I am putting around 1500km on the odometer, per month. Most of the petrol consumption is coming from steep hill climbs on the work commute return leg or highway during weekend drives.

[@jasonblair4057]

Very interesting, pick the one you like and you will be happy. Petrol vs Diesel is fits your preference in this case. Good job on both cars BMW.

Just returned from a 4600km (3000m) road trip in my 340d across the UK and Germany. In the UK I averaged 5.2l/100km (54mpg) with a mixture of motorway and spirited B road driving. In Germany I averaged 7.1l/100km (40mpg) on the autobahn, travelling at about 180-200km/h (112-125mph) where conditions allowed. My previous car was a turbo petrol, where the consumption seemed to go up exponentially as you increase speed. The diesel consumption seems to be more linear, so the benefits of running a diesel in countries with higher speed limits are even clearer.

During the fuel crisis I got 71mpg over 103 miles with my pre LCI G21 M340d in adaptive driving mode and 730 miles out of that 1 tank of fuel (with photo evidence of the driving data). Can't ever get it lower than 32mpg with heavily 'spirited' driving. For a car that Joe has proven can also do 0-60 in 4.69, and never feels like it runs out of diesel 'puff' and still sounds bloody good (don't get me wrong I'd love the M340i exhaust note) the engine with the mild hybrid is an absolute masterclass of engineering.
