Which Cars Have A BMW B58 Engine Under The Hood?
BMW has a bit of a hit-or-miss reputation when it comes to engines. While the company has created some incredibly reliable BMW models, it’s also been responsible for some wallet-draining duds. BMW has been producing turbocharged engines since the 1970s, but the brand truly began taking production turbocharged engines seriously in the mid-2000s. Initial attempts with engines like the N54 and N63 hurt BMW’s reputation of reliability for years after their release, but BMW has ironed out most of the major issues with those earlier engines.
These days, BMW creates some of the most reliable turbocharged engines on the planet, with the B58 representing the best the company has to offer. The 3.0-liter turbocharged inline-six was introduced as a crown jewel of BMW’s modular engine family in 2015 – a blank-sheet engine series that BMW designed to be as versatile, reliable, efficient, and powerful as possible. Taking advantage of BMW’s TwinPower turbo technology — in addition to other performance and efficiency-focused features like double-VANOS variable valve timing, Valvetronic variable valve lift, and high-pressure direct injection— the B58 was the most celebrated and advanced inline-six engine BMW had ever created in 2015.
Versatility truly is the B58’s strongest characteristic. It powers performance models, including high-trim F-chassis cars like the 340i and M240i. However, it can also be found under the hoods of some of BMW’s largest and heaviest vehicles, like the X3, X4, X5, 7-Series, and even the enormous X7 land yacht. That doesn’t even include non-BMW vehicles like the latest generation Toyota Supra, which also features a B58 powerplant.
The B58 has continued to evolve with time
BMW has never been very straightforward when it comes to its engine naming scheme. Like many other BMW engines, the B58 has a number of different versions that correspond to various tuning differences and upgrades. In 2018, BMW introduced a massive update to the B58, changing major features like the cylinder head design, fueling system, cooling system, and timing chain. In the BMW community, this newer iteration is called the B58 technical update, or B58TU for short. The update also split the B58 engine series into ‘middle output’ and ‘high output’ versions, with middle output B58s producing 335 horsepower and the high output versions producing 382 horsepower.
After the B58’s first technical update, non-performance models received the middle output variant of the B58 while performance models received the high output variant. For example, models ending with the 40i designation built between 2018 and 2023, including the G05 X5 xDrive40i, G07 X7 xDrive40i, and the G30 and G31 540i (among others), used the 335 horsepower B58. Between 2018 and 2024, performance models marked with an ‘M’ preceding their model number, such as the G20 and G21 M340i and G01 X3 M40i, used the 382 horsepower high output variant.
BMW released another technical update for the B58 engine — known as the B58TU2 — in 2023. The major differences include upgrades to the VANOS variable valve timing system and the integration of a new hybrid system, bumping power output to 375 horsepower.
Which BMW Models Have The B58 Engine?
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 a BMW unit?
The BMW B58 engine is available in a high-performance variant called the S58 engine. On the F97 X3 M and F98 X4 M, it made its debut.
The S58 has a number of improvements over the base B58 that enable it to produce higher power and torque across a wider range of revs. Instead of the single twin-scroll turbo on the B58, the S58 has two mono-scroll turbos. The air-to-water intercooler and wastegate on the turbochargers are electronically regulated. When the engine is turned off, a backup electric pump ensures that the turbos cool down.
Additionally, a high durability chrome-molybdenum heat-treated steel forged crankshaft is used. High-performance connecting rods and a unique crankshaft that connects to forged MAHLE pistons were also used in BMW’s S58 setup. The pistons and rings on the S58 are manufactured by MAHLE Motorsport, a firm that is known for their forged racing pistons and rings.
There are two different songs for the S58. The less powerful model has 473 horsepower at 6,250 rpm and 443 lb-ft of torque between 2,600 and 5,950 rpm. The top-spec version’s peak output is increased to 503 horsepower at 6,250 RPM but torque remains unchanged. While the latter is used on the M Competition versions, the former is used to power the basic M cars.
The most potent production inline-six engine BMW has yet manufactured is the S58.
The B58 engine is it present in the BMW 5 Series?
Seven different B58 engine variants have been created since 2015, and they are utilized extensively across the whole BMW lineup. A summary of each version’s usage is given below: B58B30M0 (4 models from 2015-2017 to present) (4 models from 2015-2017 to present) – Found in the X3, X4, 7 Series, 4 Series, 3 Series, 1 Series, 2 Series, 5 Series, and 6 Series.
Is the B58 engine present in the BMW 440i?
A 3.0L Twin Turbo charged 6-cylinder engine is also found in the BMW 440i. The 435’s N55 engine produces 300 horsepower and 300 lb-ft of torque. The 440’s B58 engine produces 320 horsepower and 330 lb-ft of torque.
Does the B58 engine fit the 335i?
The 335i and 340i models cover multiple generations of engines and chassis:
- 2007-2010 E90/E92 335i (N54 engine) (N54 engine)
- 2010-2013 E90/E92 335i (N55 engine) (N55 engine)
- F30/F32 335i Sedan/435i Coupe, 2013-2015 (N55 engine)
- 2016-2019 F30 340i (B58 engine) (B58 engine)
- 2016-2020 F32 440i (B58 engine) (B58 engine)
- 2019 and up G20 M340i (B58TU engine)
Both the E90 sedan and E92 coupe carried the 335i badge. BMW changed the name of coupes to the 4 series when it introduced the F chassis in 2013.
As you can see, if we compare every 335i and 340i model that is offered, there is a lot to unpack. The older 335i vehicles have both the N54 and N55 engine, while the more recent 340i variants come with the B58 or an upgraded B58TU. Both have crossed two chassis generations.
Most likely aren’t taking the extremes into account, such the 2021 G22 M440i vs. the 2007 E90 335i. To keep this comparison cohesive, we’ll make a few references to the majority of models. However, the F-chassis 335i vs 340i is the main topic of this article.
What engine outperforms B58?
To get right to the point, I adore the BMW B58’s direction. Even though some people will criticize the cost-cutting measure of creating engines with the same specifications, I think it is a great concept. Instead of completely redesigning engines, it gives the chance to improve just one design. Having said that, I wouldn’t currently purchase a BMW B58.
The B58 is currently too far from being a great performance value, but it will be in the future. You can find an M3 with an S55 engine for about $10,000 more than a B58 vehicle. Although the B58 is a fantastic engine, the S55 is superior. Much better when you consider that the M3 comes with the entire package and will retain its value better. The B58 has the lowest value rating as a result. The B58 also receives the lowest ranking for tuneability because it is the newest engine on the list and only has one turbo. In comparison to the N54, N55, and S55, reliability receives the highest ratings.
