BMW’s B58 and S58 engines are iconic examples of their dedication to turbocharged inline-6 technology. The BMW S58 stands out in particular with its shorter stroke that allows it to rev higher and generate more horsepower.
It also boasts a redline that’s more in keeping with high-revving M-engines; however, its twin turbo setup limits top-end power and reduces exhaust note significantly. For BMW B58 vs S58, there are also some important examples from many different units.
The B58 engine is used in models that are not in the M series, such as the 340i and 540i, while the S58 engine is usually used in high-performance car models such as the M3 and M4.
Even though S59 is a high-performance engine designed, B58 has a smooth power delivery and broad torque curve. Let’s discover the details of these motors’s details with different features.
The BMW B58 engine is an efficient and dependable piece of engineering. Equipped with innovative technology to maximize efficiency and performance, this motor makes an excellent choice for luxury vehicles or sports cars with high-performance capabilities. When properly maintained, its lifespan should last years without issue.
The B58 engine has shown remarkable reliability improvements over its predecessor, the N55. There have been reports of issues, but these tend to be relatively rare. With its sturdy construction that can withstand aggressive tuning and abuse as well as its impressive power output capabilities.
However, buyers of vehicles powered by this engine should keep certain considerations in mind before making their purchase. Some owners have reported issues with the coolant reservoir which may leak and cause irreparable engine damage. Furthermore, this engine is susceptible to oil contamination caused by dirt entering through its oil filter system.
BMW has addressed these concerns by installing larger radiators and an engine oil cooler. Furthermore, their engine includes a map-controlled oil pump to soften internal components under heavy lateral acceleration.
In terms of efficiency, B58 is one step ahead of S58. Since S58 is a high-performance engine it requires more energy to run.
The B58 engine from BMW is one of its finest designs and has proved itself one of the most dependable engines ever built. Still relatively young, it will be interesting to observe whether its performance and dependability remain outstanding over time.
The S58 engine found in the F97 X3 M and X4 M Competition models is even more remarkable; producing 473 horsepower and 443 lb-ft of torque as standard; however, with additional modifications on offer in M3 Competition and M4 Competition models this can even reach 503 horsepower and 479 lb-ft of torque!
This is an important detail for BMW B58 vs S58.
These engines can generate so much power due to their twin-turbocharger systems and electronically controlled wastegates, along with air-to-water intercoolers. All of this allows them to produce more torque at lower RPMs for faster acceleration and speed.
Like its B58 predecessor, the S58 uses a dual VANOS variable valve timing system and dual pressure fuel pump. As with its counterpart, its design utilizes closed deck technology; that is, metal blocks surround all cylinders except those which allow coolant flow through. This prevents overheating.
The S58 also features an advanced cooling system consisting of two coolers and a water-to-air intercooler, with one cooler housing coolant for radiator cooling and another holding coolant for turbocharger cooling; these components help the engine maintain peak power at high loads.
There are some differences in performance for BMW B58 vs S58. The BMW B58 engine is an efficient and dependable solution that is found across various models by BMW. The smooth power delivery makes the B58 an excellent choice for drivers seeking maximum enjoyment from their ride.
But for an authentic high-performance experience, BMW’s S58 engine may be your answer. This inline six-cylinder replaces the iconic S55 and debuts under the hood of their new X3 M and X4 M performance vehicles; producing up to 503 horsepower delivering an exciting driving experience. This is one of the most well-known examples for BMW B58 vs S58 .
This engine is extremely responsive to input from its driver, providing impressive torque across its entire rev range. Additionally, its double-overhead camshaft cylinder head features BMW’s Valvetronic variable valve lift system for impressive power and efficiency; further contributing to its exceptional performance is a forged crankshaft and MAHLE pistons – another factor in its outstanding performance.
Of course, increasing the S58’s power output up to 800 wheel horsepower requires a fully built engine with modifications such as stronger transmission modifications. Furthermore, newer 2021 and 2022 BMW vehicles contain locked DMEs which must be unlocked using a special service provider in order to be unlocked.
As BMW’s latest engine, the B58 faces some lofty expectations. Boasting legendary reliability similar to 2JZ engines like the 135i and M3, it may be hard to imagine another engine surpassing this one; but that may just be what S58 can achieve! Boasting an enhanced engine block design with forged internals for increased horsepower output and upgraded suspension components for racing or performance driving applications – these powerful machines make an impressionable statement about BMW engineering excellence!
As a result of its impressive performance, the S58 has become a go-to car for racers and enthusiasts. With some bolt-on modifications, an S58 can reach over 650 wheel horsepower with stock internals. When coupled with upgraded turbos and tuned correctly, over 1000 HP can often be achieved!
Although the S58 offers much, it does have some drawbacks. First and foremost is its limited availability – only certain BMW models feature this engine, limiting your options if you are searching for one with this powertrain. There are no dramatic differences in the value for BMW B58 vs S58.
Additionally, the S58 engine is more complex than its predecessors and therefore more prone to issues like overheating and premature wear; consequently it may cost more to repair or maintain than previous BMW engines. It can be said that their values are closer in today’s markets.
