BMW's Biggest Mistake? Why The E90 320si Could Have Been So Much More

[@clivethecorvette]

I've owned two 320si, my current one is on 153,000 miles, original engine. The video sums the car up well, one other detail to add, they have hydraulic power steering, which does help with feel over the regular 320i electric steering. I have to agree with the downsides: poor fuel economy and mediocre straight line performance and some owners reporting serious cylinder liner issues. Despite all that I like them, they are different, have a genuine motorsport back story and thanks to so many of them being broken there are relatively few remaining. The upside to this reputation is that prices are very low; consider that IF the engine was bombproof and made more power they would probably be priced beyond my means as a daily driver. Besides, if you find one that has had steel liners and new cam chain they should be tough, I don't know of any crank, rod, piston or top end failures. The top end shares many similarities with the S54 M engine, with solid lifters (the same parts used) and actually has stronger rockers than the M part (they are used by a number of race teams in S54 engines). My commute to work has plenty of roundabouts, the grip is impressive and makes working the engine between 4k and 7k revs great fun. I feel that part of the secret to keeping the engine healthy is more regular oil changes and a very careful warm up process before giving it full throttle. I fitted a sump heating pad, so on colder UK mornings I plug the car in for a few hours before driving. As long as you accept the car for what it is, at a currently sensible purchase price in this crazy used car market you could be happy. www.racelife.co.uk/mycars

[@CarNitty]

I love how I can just search for a car off the top of my head an 90% of the time, I'm greeted with a JayEmm review. Just perfection.

[@seigma5340]

First of all, thank you Jay for reviewing this car, it has a special place in my heart and so I want to step in to add a few details. The history of BMW 4cyl performance engines has been kind of overshadowed by its popular 6cyls, but it's actually very interesting. The S14 developed for the E30 M3 was an engine that was already old when it came out, in fact, bmw put it in the M3 while simultaneously developing its successor that should have been derived by the new M40 engine. So with the E30 we start to have 2 lines of 4cyl, a standard one (M40) and a performance oriented one (namely the M42 that powered the E30 318is). BMW developed a motorsport variant of the M42, it was codenamed S42 and it was used to compete on touring championships with 2L displacement limits in the 90s. The M42 (and S42) was carried on to the E36 generation in the 318is, where it evolved into the M44, the last iteration of this line of engines. Imagine that in north america they got the M42 and M44 into the base E36 318i, so they kinda got screwed with the M3 but got lucky with the base model. The E36 marked the end to the development of the performance line of 4 cyl engines... Or so it seemed. The 4 cyls that came after the M43 and M43 were codenamed N40 and N42 and were developed with a lot of new BMW technologies, like the aluminum block, double vanos, valvetronic, etc, with the N40 being the "cheaper version" and therefore not having valvetronic, but limited to 1.6L of displacement and used only in certain market on the E46 compact. The N40 and N42 received an update around the E90 launch, namely the N45 and N46, and here's the catch: due to the N45 not having valvetronic, it was able to rev higher, and thus it was chosen by BMW for the 2L displacement motorsport. I guess they did this 320si because the regular N45 was available only as 1.6L displacement. So all in all, this 320si is like the spiritual successor to the E36 318is. If there's a guy that knows a lot about BMW 4cyls, that's Bruno from BDS motorsport. He used to tune E36 M42 and M44 engines and then moved to the N45 in the E87 116i, you can even find a video here on yt of his tuned 116i. I remember in one of his lives he talked about the E90 320si engine and essentially said it was flawed because some components were made at motorsport levels, and others were recycled from BMW partsbin or just made cheaply compared to the racing version of the N45, backing up the idea that they made this car more because they needed to homologate the 2L N45 rather than to make a 318is successor. Very interesting anyway. Lastly, while it's true that the N43 (N46 successor) makes roughly the same power as the 2L N45, it's also true that it's nowhere near as rev happy and fun to drive as the latter.

[@mikaeljohnsson4982]

Excellent summary and history lesson! I can only add that the competition version of the engine in the 320si was named P45 (which I'm sure you knew). When I think about it: It must have been here around the race engine versions got from being renamed to "S" to "P" instead?

[@mikaeljohnsson4982]

Thank you Jay for reviewing this car. I agree with the conclusion. It could have been so much more if BMW had only tried to squeeze out say 190-200 horsepower. Now it is obvious that they put all the gunpowder on the race car, the street car was an element to build from, nothing more. At least when it comes to the engine. I considered one but chose a 335i instead. With the right spec it looks the same while it has completely different resources. But here are some things I want to add / correct: * One more thing differs externally: All 320si have black exterior mirrors. * There was in fact a motorsport livery to get! (Depending on market perhaps.) Not the variant you show us but the stripes that shows the nationality of Andy Priaulx and Jörg Müller's race cars in WTCC 2006 you could actually get, alternatively the same stripes in BMW Motorsport's colors. But few first owners seem to have taken advantage of this. * I know that the suspension angles were more aggressive from the factory than for a regular 320i with sports suspension. As I remember it, the car impresses much more in curves than in straight stretches.

[@mrslowly9985]

I never heard of this one, but I had a same year 318i and thought it could of done with a turbocharger. So why BMW went to the expense of that engine and didn't just whack a blower on it is confusing! They could of got 240bhp easily and reliably with all those lovely noises to boot!

[@joebanks9529]

I had the 320i edition m sport 08reg. Same alloys & engine, but without the carbon fiber. I had it just over 2 years & spent more money then you can imagine just to keep it on the road. Lamda bank 1 & 2, Nox & o2 sensors. ABS sensors. reluctor rings. Had to change whole diff as bearings had gone. HP fuel pump was leaking fuel onto the exhaust manifold at one point. I-drive botton stopped working. Waterpump & theromstate made out of plastic, so that too. Coil packs burning out. There's more I just cant remember it all now. The car had like 60k miles on it & looked lovely. When the engine managment light wasnt on it drove lovely lol. Sulpherised cat was another , but that was due to the Nox sensor. My first & last BM trouble you. I know enough about cars to know it was all design flaws or where the cost cutter at BMW had swapped everything possible from metal to plastic. Now, many years later I have an 08 civic type r with close to 100k miles on it currently. This car has no way been looked after well & no where near the BMW had been. But yet after 2 years driving the civic only real issue was a seized caliper. It cost almost half what the BM cost to buy orignally to.

At the time were a really nice car. A mate had one ex demo with a lot of optional spec and ran it for a good number of years. I dont think it blew up, rather it started suffering lots of electrical gremlins so got shot of it. Engine was nice, yes not that quick but revvy and made a nice noise - lots of character. I believe BMW actually hand finished the motors at Hams Hall. I looked at these a few years back and most were being sold for spare or repair, or being broken for parts so I guess they are becoming quite rare......any 6 cylinder variant, even a 325i is better though.

I watched the vid twice. NOw, that I recently bought an e90. Lucky Brit’s get to have homologation special and it’s the cheapest in the range just about. Personally I would prefer more performance, but a more peaky/tuned 2 litre would suffer more down low. I would consider re-sleeving the block to get more capacity say 2.2-2.3 litres ideally, assuming the block design allows it. Perhaps offset grinding a crank, or looking to see if there is a bmw crank from another engine that could be made to fit. 220hp, 50-75kg of weight saving and you could call it a 320(c)si….

[@VDPEFi]

I remember a few of these coming through the place I used to work as used/ex lease, they didn't sell as well as imagined, very basic spec and back then if it didn't have idrive and leather an e90 wouldn't sell. Nobody could see any heritage in it, it was a bodykit on a model nobody wanted.

[@patrickbateman6885]

I own a 2011 BMW 323i E90 LCI. I'm trading it in this week on a 2016 BMW 420d. It brings me to tears to sell this car as it's the car that saved my life. I've owned it for 9 years and I haven't had a single issue. The last of the small inline 6s I think are arguably the best motor's BMW ever made and I love it so much, however the low end torque is non existent. The way it handles and steers it just makes your jaw drop. Easily the best car I've ever owned. I'm only upgrading it as despite it's record of not having any problems, I am admittedly getting worried as it gets older and I don't want or neither really have the money to repair things when they will inevitably go wrong. I'm also getting a 4 Series as it's newer, has majority of the latest safety kit, is in my opinion one of the top looking cars BMW have produced and the 4 Series since driving one at launch has been my wife's favourite car and one of mine as well. Also this will mainly be my wife's car and she didn't want a 3 Series or a 5 Series, plus my wife only drives around town as she is a stay at home wife/mum and around town the 6 cylinder averages 12 litres per 100 urban, while the 420d urban averages 5.1 per 100. That will be saving me thousands of dollars per year. Also it has 75% more torque than my 323i and the same as a 435i and it didn't feel far off the big V8 Holden Commodores/Caprice's I owned which had 500NM+. I'll probably cry when I say goodbye to my 323i, however all good things must come to an end. Preferably I would of wanted a 430i, but here in Australia there is no new or used cars around and all the prices are up.

[@jondonnelly3]

TLDR

[@GoldenCroc]

Two things: be careful about driving a diesel mostly around town. They dont like it. At all. Secondly, I see what you are getting at, but I must point out torque numbers dont mean anything for acceleration. Its power that do. Common mistake/misuse of wording though, for sure.

[@patrickbateman6885]

@@GoldenCroc I meant torque. Sorry I wrote this at 2am here in Melbourne and I'm dead tired. Also I will definitely drive it to where I work in the city a few times a month (I live in Rowville, which is the outer east of Melbourne) and it's 32km from my house to work. I'll also make sure to give it that big drive each month so the engine doesn't clog up like I've heard about the diesels in X5s. I'm hoping in 2 to 3 years to trade in the 420d on probably a G20 330i or maybe then the Inline 6 Mazda 6 will be on sale which will probably be worth a shout.

Back in 2009 I was in the market for an e90, I only wanted petrol and the 320si ticked many boxes having just sold my second Honda S2000! I thought a high revving engine was still the way to go! The si fell far short of the mark so I bought a 2 year old 325i for the lovely 6 cylinderness, it genuinely only managed 23 mpg but had a fair bit more power, it was a good choice, I loved that car, eventually part exchanged it for a Z4M…….that’s a whole different story!

[@MrRoyck10]

During the golden era of BMW this car was the product of that period when BMW was the ultimate driving machine, I love old school stra8 six Bimmers with its signature smooth revving engines. This car looks stunning but l love the sound of the straight six in the e86, it sounds good accompanied with excellent induction noise and it can keep up with modern BMWs albeit not as fast 💨 as the turbo era. Old BMWs are very characterful to drive when compared to the computer aided car. Thanks JayEmm.

I drive a 323i which I’m trading in this for week for a 420d. It 110% isn’t as fast as a turbo BMW as it has absolutely no low end torque whatsoever.

[@MrFlazz99]

Quite right to point out that diesel was the big thing back when this was launched (and still is, as far as I'm concerned). I could never understand why BMW bothered with a petrol 2-litre engine at all,. considering that the diesel options were as good if not better in performance terms (and would have offered better economy as well). Even the six-pot 2.2-litre motor of the E39-vintage 520i seemed pointless to me - unless ALL you wanted was a six-pot soundtrack. Fair enough - now I understand the reason for the four-pot 2-litre, but as you pointed out, if they were going to do this homologation-special motor they could at least have made it a bit more 'special'!
