Is The BMW Inline 6 Reliable?

Modern BMW engines are those that made their debut in vehicles built within the last 25 years. A secondhand BMW becomes a classic the older it gets.

One dependable BMW engine, the N52 inline-6 featured in the E90 325i, 328i, and 330i, has already been covered in detail. This engine isn’t ideal, but because it isn’t turbocharged, it doesn’t have the issues of the current N54 engine. Additionally, the N52 is free of the rod-bearing problem that plagued the E90 M3.

Make sure the BMW you’re looking at has the 2009 models’ upgraded cylinder head if it has a N52 engine. According to BMW Tuning, this eliminates the oil-related valve-tick problem that frequently arises in older vehicles. Automobiles manufactured in 2008 and earlier may experience steering lock and ABS module failure.

The M54 inline-6 is another dependable contemporary BMW engine. This engine is found in the 2000–2006 E46 3 Series, as well as modern Z3 and Z4 roadsters and X3 and X5 SUVs, according to BMW Tuning. And it has a reputation for performing dependably even after traveling a great deal of distance.

Having saying that, the M54 engine isn’t entirely faultless. It includes BMW’s VANOS technology, which controls the valvetrain, just like the N52. The system’s solenoids and seals deteriorate and fail over time. The DISA valve on the intake manifold and the plastic valve cover both have a similar tendency to deteriorate.

But contemporary spare components come in better and more durable materials. Additionally, certain M54s have loose oil pump nuts, which could fall off and cause an engine to fail. However, according to BMW Tuning, most have already been better secured with Loctite.

The M44 4-cylinder engine, which can be found in the 1996-1999 BMW Z3 and E36 318ti, is the last option, according to Turner Motorsports. According to UnixNerd, the M44 is descended from the M10 4-cylinder used in the E30 3 Series and was preceded by the M42 and M40 engines.

Although the S14 engine in the M10 and E30 M3 is quite robust, according to BimmerLife, the M44 is more tolerable. Not the least of which is that it features an OBD-II port that is current. It’s also a reliable engine, according to UnixNerd, with the exception of certain age-related gasket and tubing problems.

The 6 BMW Engines That Are Most Reliable

BMW is known for producing high-end vehicles. You could be wondering if they are trustworthy, and the answer is that they are absolutely trustworthy. Even though they have quite high price tags, they are still worth the money. They have superb and potent engines that will allow you to use them at their maximum speed.

BMW’s most dependable six-cylinder engine is the N52.

BMW’s smart nomenclatures will be recognizable to those of you who have seen the propensity of automakers to utilize perplexing name schemes. This naming technique was initially used on their first vehicle, the BMW 3/15 PS; the logic behind how the power and tax rate were shown is still prominent in today’s society. So when 2021 rolls around, the 318i, 530i, and Toyota Z4 30i will still be standing to represent history.

When you learn that the 18i from the 318i represents the power in kilowatts rather than the engine displacement, confusion sets in. Converting the 18 kw to hp only yields a value of 24 hp, which only serves to fuel the confusion. You see, a kw bracket corresponds to the value 18. You can rest easy knowing your brand-new 3 series doesn’t have 24 horsepower with a value of 45 corresponding to a kw bracket of 300–350 kw.

For those who are not familiar, the N52 was the first BMW straight-six engine to use a composite block made of magnesium and aluminum.

BMW still produces inline 6 engines?

In an interview with Auto Motor und Sport, the former CEO of M, Markus Flasch, who is now in charge of BMW’s high-end big automobiles, was surprisingly forthcoming with information regarding impending goods. The M3 Touring wasn’t originally planned, and the M4 CSL will reduce more than 100 kilograms (220 pounds), but the man in charge of the M division for the previous three years revealed another nugget.

Markus Flasch promised M enthusiasts that the powerful engines will be around for a sizable amount of time when asked by the German magazine how BMW plans to make its large-displacement engines cleaner to meet Euro 7 requirements due in 2025: We have technical options to maintain our inline six-cylinder combustion engine in the range for both road and racing vehicles until at least the end of the decade, so don’t worry.

He continued by saying that regardless of how stringent the Euro 7 emissions regulations become, the inline-six will comply with them since engineers had found a way to better optimize the combustion process. He wasn’t just talking about the 3.0-liter engine, so the news continues getting better. The larger V8 will also receive these adjustments, according to the former M CEO, in order to comply with ever-stricter emissions regulations.

Markus Flasch was asked by Auto Motor und Sport if there were any intentions to release a M vehicle with an electrified four-cylinder engine, but he responded that BMW is not currently looking into the possibilities of a high-performance hybrid model with a four-pot. With the next-generation C63 (and consequently the GLC 63), Mercedes-AMG will achieve just that by ditching the V8 in favor of a considerably smaller 2.0-liter gasoline engine with an electric turbocharger and an electric motor.

That is not to imply that when it comes to the engines available in M vehicles, BMW completely avoids electrification. As you are surely aware by this point, the M division will begin hybridizing the V8 in a few weeks, given that the XM SUV concept will be unveiled on November 29.

An SUV-shaped dedicated M vehicle would reportedly have a newly developed eight-cylinder engine paired with an electric motor to provide more than 700 horsepower. However, the “all-new high-powered, hybrid-electric” model is scheduled to be constructed in Spartanburg as the “new BMW M flagship car,” and that is the only official information that is currently available.

Older BMWs are they reliable?

When examining whether or not BMWs are reliable, the subject of age is crucial. It is frequently discovered that older BMWs—generally those produced in the late 1990s and early 2000s—are more dependable than newer BMWs. Though not always the case, take note. This applies to the majority of other brands as well, not only BMW. Early automobiles from the era have rudimentary engineering and construction. There is less of a possibility that something could go wrong because of the simplicity of the mechanical or electronic components.

Even if they do, correcting them won’t be that expensive. Newer cars, on the other hand, are quite high-tech. The iDrive entertainment system, external safety sensors, as well as the extensive web of wiring, computers, and electrics running throughout the full length of the car, are just a few of the many electrical components found in BMWs in particular. The modern engineering of newer BMWs can make them more prone to problems. Not to mention pricey, particularly once the warranty expires.

In reality, the majority of the components and labor needed to maintain and repair BMWs are identical to those for other models. Certain parts inevitably need to be replaced. The same issues might arise with a regular Honda or Toyota, but BMW’s high-performance parts will cost more just for the raw materials. In addition, labor costs are greater for BMWs because they require more time from mechanics than the ordinary vehicle. In general, you can easily expect your BMW repair price to be $1,000 or more.

What benefits does an inline 6 offer?

advantages of the straight-six Straight-six engines are typically easier to work on due to its simplicity, and the I6 is frequently a better option for the novice mechanic due to its layout, which allows for greater access to spark plugs, leads, and ancillaries when maintenance work needs to be carried out.

The 268-hp 330i, according to BimmerLife, is one of the most potent naturally-aspirated BMWs ever produced.

Why are inline 6’s so great?

Additionally, inline-sixes are simpler than other layouts. That means a V-6 has half the camshafts and cylinder heads, which results in less weight and fewer parts, which lowers the cost and reduces the likelihood that anything would break after many years of use.
