In 2015, the BMWB58 turbocharged straight-six engine went into production. The N55 was replaced by the B58, which debuted with the F30 340i.
Following the B38 and B48 engines, the B58 is a member of BMW’s new modular engine family, which includes engines with 500 cc (30.5 cu in) of displacement per cylinder.
The B58 engine, which is found in the 340i and 440i, was designated one of the world’s ten best engines in 2016, in 2018, in 2022 (M240i), in X3 and X4 M40i, in Z4 M40i, in 2019 (X5), and in 2020 (M240i) (M340i).
The high performance variant of the B58 engine is the S58, which debuted in early 2019.

Versatility
BMW crams the B58 engine into practically everything. That isn’t odd in and of itself because standardization of vehicle engines is nothing new, regardless of brand. The B58’s range of capabilities, though, is astounding. It drives real performance vehicles like the Z4 M40i, X3 M40i, M240i, and M340i. The BMW 540i, the X5 xDrive40i, and even the incredibly heavy X7 xDrive40i are among the standard luxury vehicles it powers. Additionally, it is economical and smooth enough to be used in plug-in hybrid vehicles like the BMW X5 xDrive45e and the 745e.
There are several engines available that can perform multiple tasks, but none of them are as good at each one as the B58. The B58 engine performs flawlessly in every situation, as if it had been designed specifically for that vehicle. When driving a BMW 745e, it’s nearly difficult to tell that the car’s engine could also be employed in a zingy, exhilarating, and entertaining performance car.
Straight-6 3.0 DOHC BMW B58 engine
The BMW B58 is a straight-6 DOHC turbocharged direct injection engine that went into production in 2015.
It was put into orbit in an F30 340i. It also belongs to BMW’s new modular engine family, which is built on 500cc-per-cylinder engines that are based on the B38 and B48. The B58 shares similar features with its N55 forerunner, including a single twin-scroll turbo, direct fuel injection, Dual Vanos, and Valvetronic.
The B58 (found in the M240i) came in first place in Ward’s list of the top 10 engines of 2017. The B58 is capable of 26 mpg while producing 335 horsepower and 369 lb-ft of torque.
Updated 3.0 liter B58 engine from BMW to power new 540i, 740i, and other vehicles with about 370 horsepower
A new version of BMW’s well-known B58 engine, which will power a number of sub-M performance cars, is currently being prepared.
The 3.0 liter turbocharged straight-six that the German carmaker has been producing since 2015 will be replaced by the new engine, which will be known as the M58B30M2.
The current engine produces 335 horsepower and is used in a variety of BMW vehicles, including the X5 xDrive40i, X7 xDrive40i, 540i, 640i, 740i, and 840i. A modified version, which is capable of 382 horsepower, also drives vehicles including the Toyota Supra, Z4 M40i, M340i, X3 M40i, X4 M40i, M440i, and M240i.
According to a rumor from BMW Blog, the upgraded B58 engine will increase upon the current 335 horsepower model and produce roughly 370 hp. It’s interesting to note that dyno testing of the outgoing B58 has shown that BMW understates its power statistics and that it actually produces about 335 horsepower at the wheels, not the crank. As a result, it’s plausible that the new 370 hp engine is actually more potent than that.
BMW will also swap out the aforementioned 382 horsepower model with its improved B58 engine. According to BMW Blog, this straight-six engine will likely have approximately 400 horsepower and gain from a number of other improvements to improve its thermal management while also making it more responsive and effective. A bigger turbocharger and a modified intake manifold are two improvements that are believed to have been introduced.
It is yet unknown which BMW vehicles will be equipped with the new B58 engine, but according to BMW Blog, the 540i and 740i will likely be among the first.
Understanding the Upgraded B58 Straight-Six
In its current configuration, the B58 engine powers a variety of vehicles, including the X5 40i, X7 xDrive 40i, 540i, 640i, 740i, and even the 840i. All of these vehicles receive a respectable 335 horsepower from the B58 engine. It is modified in the Toyota Supra, BMW Z4 M40i, M340i, X3 M40i, M440i, and M240i to produce 382 horsepower. According to a recent report from BMW Blog, the improved model will be known as M58B30M2, and the 3.0-liter engine would produce 370 horsepower in its base configuration. It should be noted that the existing B58 has shown to be significantly more potent on the dyno (335 horsepower at the wheels), so there’s a chance that the new engine may produce more than the predicted 370 horsepower.
The engine in the Supra, Z40, and different M40i models across the lineup will also be replaced by the new B58. Although no exact figures are provided for that particular engine, the outlet makes the assumption that it might be advertised at about 400 horsepower. Additionally, it would have a number of updates, such as enhanced thermal management, updated induction for improved responsiveness, and other small improvements to boost efficiency. According to reports, the two most important recent improvements are a larger turbocharger and a modified intake manifold.
It’s unclear which models the new B58 will debut in first, although the upgraded M540i and 740i are the most obvious front-runners. After 2025, the Toyota Supra and BMW Z4 are rumored to be on their way out, but a significant update due in 2023 implies they might also get the revised B58 for their final few years on the market.
Is the B58 engine present in the BMW 540i?
BMW will release a new iteration of its six-cylinder B58 engine in a matter of months. A number of new BMW vehicles, including the incoming BMW 740i and the upcoming BMW 540i, will include the B58 TU2 (B58B30M2) (G60 generation). The B58 engine that powers the modern 540i produces 335 horsepower. The updated engine is expected to produce 370 horsepower, making it the B58 engine’s most potent non-M Performance variation.
Future M Performance models of the new B58 TU2 might produce closer to 400 horsepower, given that the 382 horsepower of existing M Performance models. The new B58 engine should also have some other mechanical improvements that could make it smoother, more efficient, more responsive, and have better thermal management in addition to the added power. According to rumors, the updated engine will include a fully redesigned intake manifold and a bigger turbo.
According to our sources, the G60 generation will be split almost evenly between hybrid and electric vehicle (EV) models, with the latter utilising known powertrains and electric motors like to those we’ll likely see on the iX and i4. Power output ranges from around 300 HP to about 370 HP, over 400 HP, and even over 500 HP for the most potent options. We may see an electric 5 Series with 100+ kWh batteries under the floor since the battery packs will also be shared with the iX and i4.
We should see 2-liter and 3-liter straight six engines coupled with variable numbers of electric motors on the hybrid front. According to our sources, they may share some components with the future 7 Series up to a point. We should see some really spectacular power outputs, especially from the 3-liter hybrid models. One of them will swap out the M550i’s V8 for a new M Performance variant, giving it a total output of over 500 HP.
Production of the G60 BMW 5 Series car is expected to begin in July 2023. It won’t be available until 2024, but the G61 5 Series Touring range will be heavily electric, exactly like the sedan. A few plug-in hybrid vehicles with a combination of four- and six-cylinder engines and one or two electric motors are what we anticipate. Of course, the drivetrain options for the electric sedan would be replicated in the all-electric i5 Touring.
Which BMW B58 engine is the best?
The BMW B58 engine is an absolute joy to use when it comes to the fun stuff—performance automobiles and other things—largely because of its power. It produces 382 hp and 369 lb-ft of torque when equipped with the M Performance specification, which applies to all of the aforementioned M40i versions. in writing. It feels like it has 100 more horses than that in the back. With its powerful pulling ability, even large SUVs can move quickly.
However, it’s not simply the power itself, but also how it’s delivered. There is essentially little turbo lag, and torque is present throughout the rev range. The B58 erupts when the go pedal is pressed in any gear and at any rpm, with a power surge that seems to never end. Any automobile with a B58 engine makes driving a real treat because of the power at your right foot. As soon as you drive any other six-cylinder engine in its class from any other manufacturer, you’ll understand how unique the power delivery of the B58 is.
What year is the B58 in the BMW 340i?
Yes, I did say four words, and “and” counts. Putting technicalities aside, the B58 engine is a truly outstanding achievement and sets a standard that other manufacturers would aspire to match if the internal combustion engine didn’t appear destined for the garbage can. Let’s begin with a succinct overview:
The B58 was introduced in 2015 and was initially used in the F30 340i (that is, the 2015 BMW 3 Series sedan—and you thought the Toyota bZ4X name was a mouthful). The N55 engine that it succeeded has been employed in at least 43 different BMW models since 2009, ranging from the 135i to the X6 xDrive35i, excluding the S55 high-performance variants found in more expensive M vehicles. The oil filter housing leaks and valve cover gasket issues were well known, but the B58 had huge shoes to fill since it was used in so many different applications.
The straight-6 turbocharged B58 has been a home run, performing admirably in at least 52 models, including several that aren’t even BMWs! The B58 is one of a new modular engine family produced by BMW to reduce development and manufacturing costs (the entire family features 500 cc cylinder displacement, and the B58’s block is identical to the diesel equivalent B57). The B58 is so excellent that it was used in the Morgan Plus Six and, more infamously, the most recent Toyota Supra generation!
The B58 is included in every model offered by BMW, from the diminutive M140i to the enormous X7 xDrive40i. The S58 version deserves recognition because it can be found in a number of M models as well. It is very surprising how well the B58 operates in whichever car it is found in, from its lowest 322 horsepower output to its maximum 382 horsepower. There is no turbo lag to indicate that it was primarily created for commuters when utilized in a sports car. Whatever BMW wants it to do, the B58 just does it and does it like it was designed for the purpose. There is no negative NVH to suggest that the 7 Series is using a track car motor either, and when driving three-row X models with this engine, nothing about it suggests “underpowered cost-cutting measure.”
Which BMW engine is the most dependable?
BMW is known for producing high-end vehicles. You could be wondering if they are trustworthy, and the answer is that they are absolutely trustworthy. Even though they have quite high price tags, they are still worth the money. They have superb and potent engines that will allow you to use them at their maximum speed.
