Best BMW Petrol Engines

1BMW M57 – Straight-Six

BMW produced the M57 straight-six diesel engine between 1998 and 2013. The M27 is a dependable BMW engine with cast iron underpinnings that can provide a powerful 428 lb-ft of torque.

BMW equipped the 335d sedan and early X5 cars with its bulbous diesel. Considering what they were up to at the time, Land Rover even operated the dependable M27 diesel among its L322 Range Rover series.

BMW employed cast iron to stop the harm caused by diesel engine vibrations.

The M27 also has forged steel connecting rods, replacing the notoriously problematic timing belts on BMW automobiles from the 1990s with chains.

BMW B48 – Inline Four

For vehicles built in the 2015 model year, BMW created the B48 inline-four engines to replace the hit-or-miss N20.

Since then, the tenacious Bavarian engine has developed into one of the top four-cylinder engines available in 2023.

BMW introduced the B48 2015 with displacements ranging from 1.6 to 2.0 liters on the F56 platform MINI.

It’s important to note that BMW models are famously expensive to maintain; according to CarEdge, the average BMW will cost ,312 in repairs and maintenance over its first 10 years.

That is over $7,000 above the industry standard for a luxury automaker.

Despite its expensive price, the B48 stands out for the sheer range of its adaptability.

With up to 302 horsepower and 332 lb-ft of torque available, the little turbocharged block drives the very underappreciated MINI John Cooper Works series!

The engine is almost ten years old, which attests to its durability as a daily driver and a performance engine in one.

BMW B58 – Straight-Six

To replace the old N55 turbocharged straight-six, BMW introduced the B58.

The B58, which debuted in 2015, continued the N55’s legacy as a highly compact six-cylinder with the robust internals expected from the Bavarian brand.

The 3.0-liter six-cylinder BMW B58 engine, which powers the M240i, the X5 SUV, and even the 745E hybrid, is one of the best engines in the world for its adaptability alone.

It can gladly create 382 horsepower and 369 lb-ft of torque, pleasing several automotive sectors.

BMW first introduced its most adaptable block in the F30 340i back in 2015, and it has since been used to power the Toyota Supra.

Toyota is known for its dependability. Therefore, the fact that they use parts from other manufacturers tells a lot.

BMW M20 – Straight-Six

The 1977-released BMW M20 straight-six, which held on until 1990, is incredibly dependable. One of BMW’s most dependable engines, the M20’s astounding 16-year production run is a remarkable monument to its dependability.

The straight-six engine arrangement has made BMW famous, and the M20 was crucial in establishing its unrivaled status as a producer of six-pot engines.

In actuality, the M20 engine of the time powers both the 325i and 525i models, with a maximum output of 169 horsepower.

The M20 superseded the very massive M30 straight-six BMW engine.

With fewer moving parts and fewer electrical components interfering with function, the M20 represented a compact, forward-thinking design.

The unbeatable block that drove the classic E30 3 Series of the 1980s was the simple M20, which had a displacement range of 2.0 to 2.7 liters.

BMW M50 – Straight-Six

Another painstakingly constructed six-cylinder engine from BMW, the M50, debuted in 1990 and lasted until 2000.

The M50’s six-cylinder engine has a displacement range of 2.0 to 2.5 liters, and it can quickly generate a meager 189 horsepower and 184 lb-ft of torque.

One of the best BMW engines ever produced is the M50.

A superb example of a BMW six-cylinder is the M50. The indestructible M50 was installed by BMW in the larger 520i and 525i E34 sedans when electronics were not commonly used.

Starting with the 1992 model year, the M50 also featured the infamous VANOS valve timing technology.

BMW M54 – Straight-Six

At the beginning of the twenty-first century, BMW introduced the M54, and the straight-six immediately joined the army of greasy blocks featured in ‘Ward’s Best Engines’ between 2001 and 2003.

The controversial E46 3 Series, including the 330i, received most of its thrust from the M54. The basic Bavarian’s maximum output is 228 horsepower and 221 lb-ft of torque, and its displacement ranges from 2.2 to 3.0 liters.

Additionally, the M54 had cylinder liners made of cast iron. The M54 is one of BMW’s most dependable engines, provided owners take care of the famously delicate VANOS unit.

BMW S54 – Straight-Six

Although the BMW S54 is the performance version of the BMWs M54 found in the E46 320i and 320Ci models, the engine itself has more in common with the 1992 BMW S50 performance engine because the block was built with cast iron rather than aluminum, as is the case with the M54 base engine.

In reality, the S54, which was created using decades of six-cylinder knowledge, has emerged as one of BMW’s most dependable performance engines ever. Some people have gone a little too far with the S54.

One of BMW’s last naturally aspirated six-cylinder engines, the BMW S54 straight-six, which debuted with a 3.2-liter displacement and a maximum output of 338 horsepower and 269 lb-ft of torque at 4,900 RPM, powered the best M3 money could buy.

BMW N52 – Straight-Six

The Bavarian N52 straight-six was discovered in 2005 and remained there until 2015. The E90 3 Series, one of BMW’s most dependable used automobiles, introduced the incredibly dependable BMW engine.

But let’s get back to the N52. The block, which had a magnesium block and an aluminum cylinder head, was the first water-cooled engine produced by BMW.

With a weight of about 355 lbs, the N52 was one of the era’s lightest six-cylinder engines because of its innovative material combination.

The 3.0-liter N52 engine’s peak output is 285 horsepower and 222 lb-ft of torque. The N52 can be found hiding inside unbreakable symbols like the E90 328i.

BMW N55 – Straight-Six

Because of the N54’s shortcomings, BMW introduced the N55. Because it was a pioneer, the N54 encountered minor electronics problems and fuel injector failure.

The N54 was their first turbocharged six-cylinder engine offered in large quantities.

The N55, on the other hand, debuted with upgraded injectors and a single twin-scroll turbocharger in place of the N55’s dual turbocharger configuration.

Consider the N55 to be the final iteration of BMW’s six-cylinder engine. N55-powered vehicles are still among the most affordable ways to drive a performance BMW with exceptional dependability.

With a 3.0-liter displacement of 315 horsepower and 332 lb-ft of torque, BMW introduced the N55 in 2009. The 335i E92 may house the N55’s most potent use.

Thanks to the consistently dependable BMW build quality, certain N55 engines have been known to surpass 1,000 horsepower.

Thanks to its hefty S62 V8, the BMW E39 M5 kicked off the sedan horsepower wars and has since evolved into one of the most dependable BMW performance vehicles ever produced.

Although some people favor the F10 M5, a ticking time bomb, the BMW 4.9-liter V8 is dependable.

Additionally, an E39 M5 with the dependable S62 V8 engine managed to travel 542,000 miles. The only problems to watch out for are the awful VANOS units that plagued the era’s BMW lineup.
