The B-series engines are modular which allows BMW to save money on costs with regards to casting the engine blocks*, and also realize savings on other associated component costs. bootmod3 for BMW B58 Engine Vehicles Now Available! Just acquired a new X3 M40i (265 kW / 355hp / 369 lb./ft.) Therefore this indicates the B58 should have a high output version (and in fact BMW now offers the M Performance Power Kit on 2016 340i, which boosts the B58 to 355 hp and 370 lb-ft). The BMW engine in the new Supra should be as reliable as traditional Toyota engines. Although N55 does have lots of technical enhancements, in some places traces of economic concern can also be found. Many of you already know that the Toyota Supra comes with a choice of two BMW-sourced engines. To be fair, BMW has definitely had its share of reliability problems over the past few years. An eternity in the making-- Dinan flash tuning is now available for a wide variety of BMW B58 powered platforms (B58B30M0 specifically). The BMW F-series B58 engine is found in a wide array of BMW vehicles (M140i, M240i, 340i, 440i). Introduction . As the successor of the BMW N55 engine, the B58 also displaces 3.0 litre (though is slightly larger at 2998cc compared to 2979cc for the N55). Theoretically speaking, a throttle body is unnecessary given the presence of the Valvetronic. bootmod3 closed beta for the B58 engines has been a great success and we're excited to … The B58 engine’s turbocharger utilizes an electrical actuator to control the wastegate valve; this is a different approach than the N55 engine, which uses a vacuum-controlled charging pressure control system. Directly comparing the B58 to the N55 the greatly reduced turbo lag is apparent, as is the additional low/med range torque. Tuning the BMW B58 "Comprehensive guide to tuning the BMW B58 engine!" With over 3 years of development spanning engine control modules (piggybacks) and engine calibrations (flash software) specifically for the B58 engine, every switch/bit has been flipped in the quest for maximum power. Certain G series models began receiving the updated B58TU1 in 2019. Because of the tight schedule, there were some aspects that BMW later found can be done better. Valvetronic used on the N55 is the 3rd generation, and the one that on the B58 is the latest 4th generation. On N55 the ECU is located under the intake plenum and therefore, cooled by the intake air. When B58 is through the 1200 mile mark I’ll give it the beans and report back. There is no fundamental change in the working principle, the major difference in the B58’s Valvetronic system is it moves the servo motor out of the valve cover (which is N55’s design), and places it outside at the top right hand side of the cylinder head. Have others experienced these issues? Your email address will not be published. Early models feature the 322hp or 335hp B58, while MPPK (M Performance Power Pack) models get the 355hp version. The B58 engine has a bore of 82 mm and stroke of 94.6 mm. Therefore, all of these engines can share many of the design and manufacturing process, and ultimately lower the total cost. The B58’s cylinder block is closed deck; while N54/55 are open-deck; B58 is using air-to-liquid intercooler, compared to N54/55’s air-to-air intercooler. How long do BMW M engines last? Warranty Direct reports and consumer reports record BMW with some of the highest rates of engine failure worldwide. It was featured in a handful of different vehicles, but ultimately it was officially phased out for the N55 in 2011, except for the 1M and Z4 35i. The B58 engine will replace the N55 engine throughout their vehicle lineup. Thanks for the very informative article. BMW F and G series vehicles - 140i 240i 340i 440i 540i 640i 740i M140i M240i X3 M40i. I have driven both – N55 (335i) and now B58 (440i GC) The latest B58 engine is totally different than the N54 and N55. Therefore, BMW uses a so-call “heat management module” on the B58, which is mechanically powered directly by the crankshaft through a serpentine belt. Not just any power … However those problems stem from electronic systems, modules and software and not from failure of hard components and systems. Compared to the unit on N55, the B58 turbocharger has a 6% larger turbine, and the compressor wheel diameter is also 10% larger, therefore the B58 gains 20% in boost pressure. That will be an engine drop job. The B58 engine represents the BMW’s latest powertrain technology: new architecture, new design ideas, new approaches. Inside the module, coolant flow rate is adjusted by a rotary valve. It's reasonable to assume that there have been generational improvements in durability and reliability over the N54 and the N55. The N54 was BMW’s first mass-produced turbocharged engine. The owners manual is not up to date for this engine and I would like to know about that tank. how do you like it? In one word: closed deck design and also the air-to-liquid intercooler, determines B58 is fundamentally different from its N54/N55 predecessors. The air-to-water intercooler on B58 is integrated into the intake plenum, which is on top of the engine and sits beneath the cylinder head. However B58 is still equipped with a real throttle body, in front of the intercooler’s entrance. Since there will be noises when the timing chain is operating, BMW placed a sound insulation foam between the cylinder head/valvetrain cover and the passenger cabin firewall. N54 was also BMW's first production turbocharged engine in decades. The B58’s smaller bore allows the engine to be shorter in overall length resulting in a stronger crankshaft, and the considerably longer stroke means longer connecting rods for reduced friction. Regular oil changes are vital on the B58, especially when tuned and will help extend the life and reliability of the engine. By nature, closed deck cylinder block is much stronger than the open deck type, therefore it is more suitable for high load and high pressure application. To have all of this info in one place is frankly awesome. They had an n55 which was reasonably reliable and b58 looks like it has many kinks on the n55 worked out. The range-topping engine, which is also the … Toyota helped BMW with the development of the B58, however, the B58 features a lot of modern technologies which aren’t exactly super reliable. Since here 6 cylinders are placed inline together, this will lead to a excessively long cylinder block, and thus hard to arrange spaces inside the engine compartment, or requires the vehicle to has a longer nose (which is unnecessary for many car models). incredible info. I understand the N55 well, but I know almost nothing about the B58. I will briefly go over some details below. The BMW B58 turbo I-6 is the core member of a completely new all-aluminum modular “B” series engine family that shares pistons, rods, valvegear and other key parts with 3- and 4-cylinder siblings, all with 500 cc cylinder displacements. Dedicated to making Supercars look slow, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). The closed-deck design and also the integrated air-to-liquid intercooler grant it absolute advantages over the previous N55. Almost all “serious” high performance turbo engine use air-to-liquid intercoolers: because it is more effective and more stable. From the below official power/torque curve chart, the power output has a plateau area after 5,000 RPM. The mechanical coolant pump avoided the hassle of possible failure of the electric type in previous BMW engines. BMW B58. So reliability doubts around the 2021 M4's engine needn't bother. Our focus of the 340i is mainly on BMW’s all-new B58 engine. Back in the start of the 21th century, there is a trend quietly emerged within the auto industry, which is the desire for power. From our 2016 340i test drive, the B58 powertrain provides unprecedented quick throttle response, the feel of turbo lag is so faint that it is almost impossible to be perceived in daily driving conditions – you have to use transmission’s manual mode to detect it. Here we have the two most discussed and bought 3-liter straight six petrol mills BMW produced in the last 10 years. A reliability score of 52 (out of a scale from zero to 100 points) earned BMW a mid-pack ranking in a list which remains dominated by Japanese manufacturers such as Toyota and Lexus, which scored 74 and 71 points respectively, and … It has a larger turbocharger with a 6 percent increase in turbine wheel size and 10 percent increase in compressor wheel diameter, resulting in a 20 percent increase in boost pressure. The B58 is part of BMW's new modular engine family - each engine using a displacement of 500 cc (30.5 cu in) per cylinder - following the B38 and B48 engine. As mentioned above, the B58’s closed deck cylinder causes more restricted coolant flow, and it raises a tougher requirement for the engine cooling system. The first auto maker that started the “power war” in the affordable pricing sector is Nissan – it released the Infiniti I35 in late 2001, equipped with the VQ35DE V6 engine which passed the 250 hp mark for the first time within entry-level luxury cars. On the N54/55 engine, they place the alternator, AC compressor, timing chain and engine oil filter assembly towards the front portion of the engine, therefore the engine’s gravity center tends to be front-biased. The automaker has not stopped in its relentless pursuit of technical refinement on all levels, and BMW engines, a long-term core competency, are no exception. Next is the intercooler. With over 3 years of development spanning engine control modules (piggybacks) and engine calibrations (flash software) specifically for the B58 engine, every switch/bit has been flipped in the quest for maximum power. BMW B58 Reliability Like the S55 engine, the B58 is a new engine with few models outside of their standard warranty but is showing early signs of being a highly reliable engine. Will this Supra carry that same weakness? The ultimate goal is to save weight. Thanks for doing such an in depth analysis of the technical changes. The B58 is still using a twin-scroll type turbocharger similar to the one on the N55, however it is larger in dimension. What’s New With the BMW B58 Engine Compared to the N54/N55. Both engines are all-aluminum 3.0L inline-six. The BMW B58 engine is a member of the company’s modular engine family used across much of BMW’s eclectic range since 2015. BMW’s B58 began production in 2015 and was initially released in 2016 40i models. Initial view is that the B58 is the more refined unit – the N55 was more fun and punchier. So I have the same question as Jim K. : What is the purpose of the second cooling system? Thank you for a well written article, a rare find theese days. Compared to the 2GR-FSE, the highest tune BMW N53 only gets 236 lb-ft from the 3.0L displacement, which is 78.7 lb-ft/L. The throttle body’s purposes are: (1) when there is a sudden load change, the Valvetronic mechanism may not react fast enough to adapt to the new operation requirements; the throttle valve can help to provide a seamless transition; (2) a slight vacuum is needed for the engine ventilation; (3) the throttle body acts as a redundant backup in case the Valvetronic malfunctions. This is also the reason why BMW never officially boost N54/55’s output to over 340 hp (because the block simply can’t take that much without risking its structural integrity). With the B58 engine, BMW finally regains its power to compete in the 350hp 6-cylinder engine sector, against Mercedes-Benz’s M276 DELA30, and also Audi’s new 3.0T V6 (to be used in the 2017 S4). On the other hand, this does not mean open deck design is bad. There are two main changes that distinguish B58 from N54/55: Let’s first take a look at B58’s closed deck design. BMW’s latest engine release is designated as the B58 engine in the 6-cylinder version. For example it carries a higher manufacturing cost; Also the coolant flow is more restricted, which prompts BMW to use a dedicated heat management module on the B58 engine. However the B58 treats this differently: it places the oil filter and its radiator, VANOS timing chain to the back of the engine. Recommend Reading: Technical Analysis – The All-New 2017 BMW 5-Series (G30). These should not be viewed as independent events: they are inter-connected and rely on each other. This is good for the weight distribution, however with the price of maintenance difficulty. On top of the fundamental level enhancements mentioned above, B58 also incorporates many remarkable new designs. This explains why for the S55 engine (used on M3/M4), BMW needs to convert the N55’s open deck block to a closed deck design. The base model, which is available in Europe and Japan, features a turbocharged, 2.0-liter four-cylinder engine that generates either 194 horsepower and 236 pound-feet of torque or 255 horsepower and 295 pound-feet of torque, depending on trim and specification. The more common inline-four and V8 layouts are also produced by BMW, and at times the company has produced inline-three, V10 and V12 engines. 2021 BMW M4 FAQs: 1. However, to deal with the situation that the turbo still need to be cooled after engine is turned off, an extra dedicated electric pump is added to the turbo unit to tackle this issue. Since the intake air no longer needs to be routed to the intercooler in the front bumper (like the N54/55), such compact design brings huge benefit for the B58: the intake path is shortened significantly, which improves throttle response. The N54/55 uses cast iron cylinder sleeve, but B58 is different: it uses one latest technology called “Electric Arc Wire Spraying”. B46 engine in the BMW 330i came within a hair of joining its B58 big brother on the list this year. The reason of not using piezo injector is due to the high sulfur content in US market’s gasoline, which makes implementing the “lean burn” feature impossible. The purpose of such geometry design is not for lower-end torque, but with consideration in packaging. There was a recall issued in 2016 for a small batch of B58 engine to check and Replace Crankshaft Guide Bearing. Thanks for the detailed description of the engine. BMW is well known for its history of inline-six (straight-six) engines, a layout it continues to use to this day despite most other manufacturers switching to a V6 layout. This type of info is really difficult to come by, it gets weighed down by all of the BS, speculative forum posts. Although the oil filter cap is hiding a little bit deep in the engine bay, it is still not too hard to reach. Is the new engine in the 2021 BMW M4 reliable? “TwinPower Turbo” which is a twin scroll single turbo, The 3 Most Common BMW M60 Engine Problems, BMW B46/B48 Intercooler & Heat Exchanger Guide, Tuning Pro – Automotive Tuning & Performance Guides. For example its crankshaft is forged, stronger than N55’s casted unit; also the piston connecting rod is also forged on the B58. B38 that powers the Mini Cooper is a hoot, too. I noticed that electrical plugs/sockets around the ECU are not sealed, it does pose a concern in terms of long term reliability under various weather elements. The engine block is identical to the diesel B57. Such design brings two major advantages: (1) it significantly reduced the installation space; (2) It brings down the engine’s total height and lowers the engine’s center of gravity. April 03, 2019 / By Srdjan Bajat. VANOS is responsible for timing adjustment, and Valvetronic is used for control the lift height of the valves and acts as the throttle body. I just acquired a 340i and am just getting familiar with it. Two weeks ago we published a review on the LCI 2016 BMW 340i. This is exactly the same for the B58. However, from the holistic view it is another story: B58 is not a single product, in fact it is a member of BMW’s latest B-series engine family. So far so good, still breaking it in so I can’t compare power yet but I can say the 340i sounds better. Automotive petrol engines. The motor is similar to the S55 engine found in the latest generation F8x M3/M4 (and new M2 competition) in that it has an indirect water-to-air charge cooling system with a supplemental front mount heat exchanger to cool the water that circulates through the … It has true performance oriented design, while the previous N54/55 have limited potential which prevents them from taking higher loads. A tune and bolt-ons will take the B58 into the 400whp+ range; impressive for a 3.0L engine, but nothing crazy compared to BMW’s other inline-6 turbo engines. Common BMW B58 40i Engine Problems. These new BMW engines were built as a replacement to the previously ubiquitous N55 model, and itself now comes in 7 versions outputting from 321hp to 382hp. What BMW had missed is it underestimated its competitors’ R&D progress, which forced BMW to release the N54 engine in hurry. The BMW B58 is a turbocharged straight-six engine, which began production in 2015. An eternity in the making-- Dinan flash tuning is now available for a wide variety of BMW B58 powered platforms (B58B30M0 engine specifically). © 2014 - 2017 YouWheel, Inc. All Rights Reserved. Therefore for those 340i owners that are out of warranty, please pray that the VANOS system does not break.

The B58 engines are extremely reliable and solid as long as they are regularly serviced and maintained. For me, that means wait… Guilty until proven innocent…. Please do more of these types of articles. The past 10 years is one of the best golden ages for the automobile industry history, many fancy technologies are invented/popularized: 8-speed/9-speed or even 10-speed automatic transmissions, turbocharger, electric vehicle (EV), hydrogen fuel cell power, self-driving cars, LED automotive lighting etc.Among these, BMW has used its turbocharge engine technology to start a whole new pag… "Some people have had B58 coolant loss issues. You may also find most of the BMW inline six engines are all undersquare, and this is exactly the same on B58 too. It is a BMW tradition to place engine ECU in the vehicle’s engine compartment. What’s more, a longer crankshaft (caused by long block) is weaker too. What is the smaller tank for? ), however nowadays its cost is lowered so significantly that even Ford uses it in the EcoBoost engine family. In fact BMW had been secretly developing the N54 for years, and it is playing a bigger game (it went for another route: turbocharging). 2. You have entered an incorrect email address! The BMW B58 is a turbocharged inline-six engine which began production in 2015. Although B58’s closed deck is structurally strong, it also has shortcomings. The new B-Series platform is designed to work in 3-, 4- and 6-cylinder variants. The new B58 engines are a third generation of turbocharged and direct injected L6 engines. At that time, 6-cylinder engines usually had around 200 hp, and the territory above 300 hp belongs to more high-end engines such as V8/V10/V12 etc. Among these, BMW has used its turbocharge engine technology to start a whole new page, from the ground-breaking N54 and the later N55, N63, N20 etc., to the latest and greatest B-series engine family (B37/38, B47/48, B57/58). This is most probably due to artificial limiting logic in the ECU software, or BMW plots that curve on purpose – since any “unconstrained” power output should be a smooth curve, not with such an abrupt plateau like this one below. Starting then, BMW was under huge peer pressure, below is the timeline overview: You can see, this is quite embarrassing for BMW 330i: Toyota 2GR-FSE not only has absolute advantage regarding horsepower output, but it also accomplished a big achievement in torque performance : 277 lb-ft from 3.5L displacement, which translates to more than 79 lb-ft per liter. Too early to tell but given the timing chain class action on the N20 and the service campaign on the N63, one can hope that BMW (and Land Rover & Mercedes Benz among others) have learned a lesson. For the B58 engine the ECU location is moved out of the engine, and it sits just beside the driver-side strut tower. Also, what is the actual boost pressure on the M40i version of the B58? Just picked up a ’17 340i M Sport a few weeks ago, I’m coming from an ’08 335i with the N54 Twin Turbo. The B58 is still using the solenoid valve injectors, not the more expensive piezo unit found in the earlier N54 and the current N63 engine. In another word: people wanted higher engine output. And the 1.5L 3-cyl. Both have what looks like coolant in them. Specifically for these models, the 3.0-liter … The benefit is less pressure loss (the longer the path the greater the loss) and slightly faster and accurate pressure control. Their new B58 engine solved many of the problems that their prior N55 engine had. Also if you're used to doing your own oil service, the filter housing is towards the back of the engine. On the other hand, turbocharged engines may be benefited from the long stroke also: because of turbo lag, it is good to have higher torque when the engine is under naturally aspiration mode, which contributes to the driver’s perceived throttle response. Very true. i am considering the same car…..or an older N55: 335i…..like the song says…..torn between two loves…. The clutch on the 335i (DCT) is way the best. One member sent me the message below. In the engine compartment photo entitled “Highlighted section is the air-to-liquid intercoolers” in the lower right there are two tanks both with caps having yellow tags. The B engines use the modular design principle: same bore, same stroke, and even same block between gasoline/diesel versions. The BMW B58 are awesome to work on and with carefully picked performance enhancements like remapping, turbo improvements and camshafts you will positively maximise your driving opportunities. Obviously N55 cannot be said to be 100% perfect, partially due to its development falls into the period of 2008 financial crisis. The B58 replaced the N55 and was launched in the F30 340i. Remember, N53 also incorporated the lean burn technology, which 2GR-FSE does not have. Recently, German automotive media outlet BimmerToday released details of the newest alterations and adjustments to the design of the updated B58, and they’re quite substantial. For your reference: plasma spray is an exotic technique previously (for example GT-R, LFA etc. The B58 replaced the N55 and was launched in the F30 340i. Open deck block is lighter and has better cooling effect, therefore it is more suitable to applications that does not call for high cylinder pressure. It has a mechanical water pump now, for example. Diesel’s don’t have short strokes. Therefore this indicates Toyota has acquired more advanced design capabilities in NA engines. Are there any common reliability problems such as the N55 plastic charge pipe that fails? There are other hints which indicate the B58 is designed as a high output engine. Where the 2JZ was a relatively simple engine, the B58 is quite a bit more complicated, and ultimately probably won’t be as reliable in the long-term. BMW’s B58 engine is highly praised as one of the best engines today. I believe the one with the large cap is the engine block/radiator reservoir. So three years later, BMW released its successor: N55. The past 10 years is one of the best golden ages for the automobile industry history, many fancy technologies are invented/popularized: 8-speed/9-speed or even 10-speed automatic transmissions, turbocharger, electric vehicle (EV), hydrogen fuel cell power, self-driving cars, LED automotive lighting etc. In this article, I will provide an in-depth review on this engine, based on multiple sources of technical information and also my observation during test drive. However, the VANOS system is a huge pain for maintenance: since it is located right behind the engine and extremely closed to the firewall, it is impossible to service the VANOS system without taking the whole engine out of the engine bay. As a response to Toyota 2GR-FSE, BMW rolled out the N54 twin-turbo engine in the following year. However because of the high heat generated from the turbocharger, on 340i’s application, BMW places a heat shield around the electrical actuator component. The B58 is part of BMW’s new modular engine design. With that being said, the B58’s closed deck design seems to cost BMW more to build. The B58 engine can be found on the US versions of the M340i, Z4 M40i, X3 M40i and X4 M40i. One major change to the B58’s fuel delivery system is each of the injector is now bolted to the rail directly, not through an extra high pressure line as in the N55. * Closed-deck engine block and BMW uses the same block for both gas and diesel variants plus the cooling/lubrication passages are the same design so costs are saved when casting … Please tell me your opinions of your B58 engine? Yes, the new 2021 BMW M4 features the S58 Series of inline-6 motors which is just a turbocharged derivative of the already proven B58 series in the older M4, X4M, and M3. Much like the N55, the B58 displaces 3.0 liter (though it’s technically a tad bigger, at 2.998L compared to 2.979L) and uses a TwinPower twin-scroll turbocharger, though the B48’s is … This is a type of the ferrum plasma spray method, which creates a thin layer (0.3 mm thick) of iron on the cylinder wall surface and thus eliminates the need for using the cylinder sleeves. The N54 was developed alongside the N53, and it’s part of BMW’s NG6 engine family. Torque per liter is a very important index for naturally aspirated (NA) engine, because it is directly related to the engine’s volumetric efficiency, which represents the auto maker’s R&D capability. Had BMW used a shorter stroke, in order to maintain the same displacement, its cylinder bore need to be much larger. Is this the cooling loop for the intercooler, or possibly an isolated system for the electrically cooled turbo? Along with the new BMW 3 Series Facelift and the G11 7 Series, the Bavarian manufacturer launched its latest 3-liter inline 6-cylinder petrol mill in the shape of the B58 engine. For me, looking at the new Supra with this B58, I’m really concerned that this engine, while perhaps a strong performer, is going to bring down the reliability of a Toyota Supra to the notoriously low levels experienced by BMW.
