The B58 is part of BMW's modular engine family, each engine using a displacement of {{convert|500|cc|cuin|1|abbr=on}} per cylinder, following the [[BMW B38|B38]] and [[BMW B48|B48]] engine.<ref>{{cite web |url=http://blog.caranddriver.com/bmws-new-three-four-and-six-cylinder-engine-family-detailed-magicked-into-being-by-laser-wielding-sentient-robots/ |title=BMW's New Three-, Four-, and Six-Cylinder Engine Family Detailed |publisher=CARandDriver |date=22 April 2011 |access-date=21 May 2016 |last=Meiners | first = Jens |archive-date=12 May 2016 |archive-url=https://web.archive.org/web/20160512184622/http://blog.caranddriver.com/bmws-new-three-four-and-six-cylinder-engine-family-detailed-magicked-into-being-by-laser-wielding-sentient-robots/ |url-status=dead }}</ref>

The [[turbocharger]] is a [[Turbocharger#Twin-scroll|twin-scroll]] design, for more efficient power delivery with less turbo lag and more power than a conventional single turbocharger, as well as for weight and space saving benefits.<ref>{{Cite web |last=bimmertips |date=2018-08-15 |title=BMW TwinPower (Twin Scroll) Turbo System explained |url=https://bimmertips.com/bmw-twinpower-twin-scroll-turbo-system-explained/ |access-date=2022-12-14 |website=BIMMERtips.com |language=en-US}}</ref> The [[intercooler]] - a water-to-air design - is integrated into the intake plenum, to reduce the volume of air between the turbocharger and the cylinders.<ref>{{cite web|title=BMW's New B58 3-liter Engine Won't Be a Tuner's Delight|url=https://www.autoevolution.com/news/bmws-new-b58-engine-wont-be-a-tuners-delight-99845.html|website=www.autoevolution.com|date=12 September 2015|access-date=30 December 2017|archive-date=1 January 2018|archive-url=https://web.archive.org/web/20180101030006/https://www.autoevolution.com/news/bmws-new-b58-engine-wont-be-a-tuners-delight-99845.html|url-status=live}}</ref><ref>{{Cite web |date=2020-09-25 |title=BMW B58 FAQ - Maintenance, Problems, Tuning & More |url=https://bmwtuning.co/bmw-b58-faq/ |access-date=2022-12-14 |website=bmwtuning.co |language=en-US}}</ref>

The B58, like its predecessor the [[BMW N55|N55]], features [[Gasoline direct injection|direct fuel injection]], [[variable valve timing]] (called [[VANOS#double vanos|double VANOS]] by BMW), and [[variable valve lift]] (called [[Valvetronic]] by BMW).<ref>{{cite web|title=Big Changes Under Hood in '16 BMW 3-Series|url=http://wardsauto.com/technology/big-changes-under-hood-16-bmw-3-series|website=www.wardsauto.com|date=15 October 2015|access-date=30 December 2017|archive-date=1 January 2018|archive-url=https://web.archive.org/web/20180101135349/http://wardsauto.com/technology/big-changes-under-hood-16-bmw-3-series|url-status=live}}</ref><ref>{{cite web|title=2017 BMW 2 Series Lineup Revealed with New Engines|url=http://www.automobilemag.com/news/942174/|website=www.automobilemag.com|date=17 May 2016|access-date=30 December 2017|archive-date=31 December 2017|archive-url=https://web.archive.org/web/20171231223235/http://www.automobilemag.com/news/942174/|url-status=live}}</ref> The redline remains at 7,000 rpm, the [[bore (engine)|bore]] and the [[stroke (engine)|stroke]] is {{convert|82x94.6|mm|in|2|abbr=on}}.

The B58 also features an engine-mounted heat encapsulation system to reduce engine wear and emissions during start-up.<ref>{{cite web |url=http://www.bmwblog.com/2015/12/11/bmws-n55-engine-among-wards-10-best-engines-for-2016/ |title=BMW's B58 engine among Wards' 10 Best engines for 2016 |publisher=BMWBlog |date=11 December 2015 |access-date=21 May 2016 | last =Boeriu | first = Horatiu}}</ref>

For durability and longevity, the rotating assembly has a forged steel crankshaft and forged connecting rods.<ref>{{Cite web |last=Stoyanov |first=Aleksandar |date=2021-04-30 |title=Watch the First Teardown of the B58 Engine Powering the 2020 Supra and Z4 |url=https://automobilefanatics.com/teardown-b58-engine-2020-supra-z4/ |access-date=2022-12-14 |website=Automobile Fanatics |language=en-US}}</ref><ref>{{Cite web |date=2021-03-09 |title=How Much Power Can The BMW B58 Handle? - B58 Engine Limits |url=https://bmwtuning.co/how-much-power-can-the-bmw-b58-handle/ |access-date=2022-12-14 |website=bmwtuning.co |language=en-US}}</ref>

As a part of BMW's modular engine family, the [[crankcase]] is a completely new design identical to the [[BMW B57|B57]] diesel version,<ref>{{cite web|title=How is the B58 engine (340i) improved from the venerable N55?

The closed deck crankcase is equipped with a completely new structure which can be identified by a complex array of ribs on the exhaust and intake side and an additional reinforcement frame on the oil pump side.

The engine was revised in 2018, dubbed "B58TU", with notable changes and improvements. The fuel system was updated with 75% increased pressure with updated high pressure fuel pump and injectors, a new particulate filter located on the exhaust system's midpipe, a new one-part timing chain as opposed to the earlier two-part, and new separate cooling circuits for the cylinder head and crankcase. For weight savings, the crankcase wall thickness and forged crankshaft were optimized, and the exhaust manifold was integrated into the cylinder head housing.<ref>{{Cite web |date=2020-02-09 |title=BMW B58 vs B58TU - Technical Update - What Is the Difference? |url=https://bmwtuning.co/b58-vs-b58tu1/ |access-date=2022-12-14 |website=bmwtuning.co |language=en-US}}</ref>

The S58 features twin mono-scroll turbochargers, a compression ratio of 9.3:1, a redline at 7,200 rpm with the [[bore (engine)|bore]] and the [[stroke (engine)|stroke]] at {{convert|84x90|mm|in|2|abbr=on}}. It also features a forged chrome molybdenum heat-treated steel crankshaft, plus forged steel connecting rods and forged aluminum pistons. The pistons are forged by [[Mahle GmbH|Mahle]] and feature their proprietary anti-friction coating.<ref name=":0">{{Cite web |date=2021-04-25 |title=BMW S58 Tuning Potential - The Most Capable BMW Engine Ever? |url=https://bmwtuning.co/bmw-s58-tuning-potential/ |access-date=2022-12-14 |website=bmwtuning.co |language=en-US}}</ref>

Like the B58, the S58 also features direct fuel injection, [[variable valve timing]] (called [[VANOS#double vanos|double VANOS]] by BMW), and [[variable valve lift]] (called [[Valvetronic]] by BMW).

As opposed to the B58, the S58 features a slightly smaller displacement, increased bore, decreased stroke, and larger valves. Compression is decreased to 9.3:1 from 11.0:1. The S58 favors top-end power and has a higher redline of 7,200 RPM.<ref name=":0" /><ref name="S58_training">{{Cite book |url=https://bmwtechinfo.bmwgroup.com/tech_training_manual/ST1926%20S58%20Engine.pdf |title=S58 Engine Technical Training |publisher=[[BMW]] |year=2019 |id=ST1926 |archive-url=https://archive.org/details/st1926s58engine/ST1926-S58-Engine/ |archive-date=2019-12-17 |url-status=dead}}</ref>

=== S58 BMW M Ignite === In 2026, BMW M announced the introduction of BMW M Ignite for the S58 engine, a pre-chamber ignition technology designed to improve combustion efficiency. The system uses an additional spark plug and ignition coil in a pre-chamber connected to the main combustion chamber; at high engine speeds and loads, it ignites part of the air-fuel mixture, after which flame jets ignite the mixture in the main chamber at multiple points. According to BMW M, the technology is intended to reduce fuel consumption under high-load conditions without reducing engine output and to help the engine comply with Euro 7 requirements.<ref>{{cite web |url=https://www.bmw-m.com/en/topics/magazine-article-pool/m-ignite-technology-for-s58.html |title=M Ignite: the new technology for the S58 engine |publisher=BMW M |date=2026-05-07 |access-date=2026-05-13 |lang=en}}</ref><ref>{{cite web |url=https://zvelta.eu/blog/bmw-m-ignite |title=BMW M Ignite: pre-chamber ignition technology for the S58 engine |website=zvelta |access-date=2026-05-13 |lang=en}}</ref>
