Design
Compared with its BMW N55 predecessor, the B58 features a 20% increase in boost pressure, a closed-deck engine block design, an increase in compression ratio to 11.0:1 and a slight increase in displacement from {{convert|2979|to|2998|cc|cuin|abbr=on}} with added weight of {{convert|8|kg|lb|abbr=on}}.
The turbocharger is a 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.{{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}} 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.{{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}}{{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}}
As per the N55, the B58 also features direct fuel injection, variable valve timing (called double Vanos by BMW), and variable valve lift (called Valvetronic by BMW).{{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}}{{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}} The redline remains at 7,000 rpm, the bore and the 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.{{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}}
For durability and longevity, the rotating assembly has a forged steel crankshaft and forged connecting rods.{{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}}{{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}}
As a part of BMW's new modular engine family, the crankcase is a completely new design identical to the B57 diesel version,{{cite web|title=How is the B58 engine (340i) improved from the venerable N55? We have answers|url=http://www.bimmerfest.com/news/872462/b58-engine-340i-technical-details-and-improvements-from-n55/|website=www.bimmerfest.com|access-date=30 December 2017|archive-date=31 December 2017|archive-url=https://web.archive.org/web/20171231212639/http://www.bimmerfest.com/news/872462/b58-engine-340i-technical-details-and-improvements-from-n55/|url-status=live}} engineered as both a gasoline and diesel engine in one common part. 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 in the catalytic converter, 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.{{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}}
Another engine revision in 2022 added port fuel injection to complement the existing direct injection system for better emissions and functionality.{{cite web | url=https://bimmerlife.com/2022/04/22/bmw-b58-inline-six-receives-technical-update/ | title=BMW B58 Inline Six Receives Second Technical Update | date=22 April 2022 }}

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.
