The 320d is the top-tier 3 Series diesel, making it the best diesel vehicle BMW has to offer. The idea that a pathetic 3 Series diesel could…

Sequential turbocharged, clean-burning, and underrated is the BMW M57

In 2009, the BMW M57 diesel made its North American premiere in either the 335d sedan or the X5 SUV. The direct-injection inline-3.31-inch six’s bore and 3.54-inch stroke enable it to dispense 182 cubic inches (3.0L) of displacement. Off the showroom floor, it produced 265 horsepower at 4,200 rpm and 425 lb-ft of torque at 1,750 rpm, however timeslips of low 14-second passes at speeds over 95 mph in various 335d’s showed that the M57 was significantly undervalued from the factory. Its special sequential turbo technology allows for quick spool up and a power curve that remains stable until 5,000 rpm. Later, more on that.

2.0i N43 B20, 6i N43 B16

Brief explanation:

For BMW fans, a new era began in 2006 and 2007. At that point, the German firm added brand-new motors to the series of engines to refresh it. A 1.6-liter N43 B16 engine with 122 horsepower and a 2-liter engine with 143 and 170 horsepower are two of them (N43 B20). Fuel was injected directly into both motors. This translates to less gasoline being used while yet achieving high performance. On the other hand, it increases the likelihood of expensive repairs and increases the complexity of installing LPG.

Among contemporary BMW motors, the N43 series engines are regarded as some of the most dependable. They are perfect for folks who are interested in the BMW E90 and typically log few kilometres each year. But issues continue to arise.

There are instances of timing chain premature wear. First and foremost, the issue pertains to vehicles built prior to 2009.

failure of the coils, which results in failure of the ignition system. The engine fault indication will illuminate in conjunction with the symptoms.

It will be discussed below how 6-cylinder engines frequently worry about this issue. However, older 4-cylinder engines can have fuel pump failure. Starting issues and a lack of traction in the upper rpm range are warning signs.

All BMW small and medium class cars featured N43 series engines. Peugeot and Mini both used the 1.6-liter engine.

It is preferable to pay attention to the older N42 and N46 engines if someone intends to put gas equipment on this engine. It’s a great option in every other respect.

Which of the current BMW engines is trustworthy?

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.

X5 xDrive M50d BMW

BMW has produced and sold some incredible turbodiesel engines over the years. The most effective of the bunch was the potent 3-liter quad-turbodiesel engine, which manufacturing regrettably ended in 2020 since the engine’s niche high-performance market share was minimal relative to BMW’s overall plan. That in no way diminishes the brilliance of the six-cylinder monster that propels the BMW X5 XDrive M50d. With 394 horsepower and 560 lb-ft of torque, it is one of the most potent diesel engines available for use in passenger cars.

This diesel engine has an exceptionally linear power delivery, smoothness, and combined fuel economy of 35 mpg.

Which is better for a BMW, gasoline or diesel?

You might not be aware of the advantages of this engine type if you have never driven a car with a modern diesel engine. Fuel economy is the primary factor to take into account when choosing a diesel engine for your next BMW. Some calculations place the efficiency of diesel engines at 30% higher than that of gas engines. They are therefore an excellent option for drivers who have a lengthy daily journey.

If you’re sick of making frequent trips to the gas station, you should think about buying a BMW with a diesel engine.

Can BMW diesel engines be trusted?

There are benefits and drawbacks to owning a BMW with a diesel engine, so let’s look at reliability to round out the list of additional things to think about. The 530d and 535d BMW Series 5 diesel versions include the same features that make the BMW Series 5 a popular pick with customers, but the diesel engines feature a 6-cylinder turbo diesel engine. The BMW contemporary diesel engine has a number of noteworthy benefits, as we have already mentioned.

Modern diesel engines are far better built and require less maintenance than diesel engines from the past. BMW achieved this feat once more by providing a solid diesel engine in the 530d and 535d.

Consumer Reports rates the engine’s overall reliability for the 2014 model year as “below average,” despite the fact that it may be well-built. As time went on, the 2015 and 2016 models became more dependable, achieving ratings of “above average” for the 535d model years 2015 and 2016 and “average” for the 535d model years 2015 and 2016, respectively. As a result, while you can save money on gasoline, you might also have to do more maintenance than usual, which is common for BMWs generally and not just the F10 diesels.

Therefore, if dependability is a high priority for you, the diesel possibilities might not be the ideal fit for you; instead, you might prefer to go with a commonplace petrol engine, of which BMW provides a wide range. However, if you want an engine that is strong and aggressive and reliability is not a top priority, it can be the right choice for you.

Is a BMW diesel better than a petrol one?

  • Previously, diesel engines were also believed to be slower, noisier, and less environmentally friendly than their petrol-powered counterparts. However, when you consider the technology used in modern car construction, this is no longer the case. As part of the EfficientDynamics program, the BMW Group has recently made considerable investments in improving and optimizing its diesel engine technology.
  • New turbo-diesel engine generations are posing a serious threat to their petrol counterparts, according to several automakers. They are comparable to them in terms of performance and noise levels in addition to smoothness.
  • Diesels are excellent for overtaking and towing because they create strong torque (pulling power) at low speeds.
  • Typically, diesel engines will get more miles per gallon than their petrol counterparts.
  • Diesel drivers benefit from lower road tax bands than petrol car owners since diesels emit less CO2.

Is the BMW 3.0 diesel an effective motor?

It’s an engine that’s rock-solid, incredibly fuel-efficient, and now quite affordable, but some of you didn’t know it existed until recently. The BMW 3.0L M57 inline-six diesel engine has arguably as much performance potential as a Cummins common-rail engine. It made its American debut in 2008 (as a 2009 model offered in the 335d) and came equipped with a special sequential turbo system (compounds), 265 horsepower, and 425 lb-ft of twist—numbers that would turn out to be underwhelming. These fast cars have excellent driveability and can accelerate from 0 to 60 mph in 5.7 seconds. They can also complete the quarter mile in low-14-second intervals with their standard engines.

When the aftermarket got a hold of the M57’s I-6 architecture and robust internals, the engine’s true potential was eventually realized. The platform has demonstrated its ability to support north of 700 hp at the wheels without the need for bottom-end improvements after the platform’s issues with the emissions system and a few other weak links have been fixed. We spoke with S&S Diesel Motorsport, the common-rail gurus who create larger piezo injectors for them, and Santjer Performance, maker of the most potent 335d in the world, to get the full lowdown on what the M57 is capable of. We immediately discovered that you can create Hellcat-like power for far less than $20,000 (including the cost of the car) without even upgrading the factory transmission. And you can enjoy yourself while driving a vehicle that can achieve almost 40 mpg on the interstate.

Which BMW 3 Series engine is the best?

It’s difficult to criticize any of the engines that are offered in the 3 Series because they all strike an outstanding balance between performance and fuel efficiency. But the M340i xDrive’s 374hp 3.0 liter six-cylinder petrol engine is unquestionably the show-stopper.

It provides plenty of power from low engine speeds and is refined, versatile, and easygoing in everyday driving. It is even capable of 40 mpg or more on a highway cruise. However, if you want to indulge in its performance potential, it can accelerate from 0 to 62 mph in 4.4 seconds, thanks in part to the traction of the four-wheel drive. While you’re performing it, it sounds fantastic as well.

A similarly swift M340d xDrive diesel version is also available. It has a 3.0 liter, six-cylinder engine with 340 horsepower, but should be more efficient, especially on long highway drives.

Which diesel engine is the most dependable?

After many years, despite its high-tech competitors, the 7.3L Powerstroke is still recognized as the most dependable diesel engine. The joint venture between Ford and International Navistar (now Navistar International) produced this diesel engine.

Ford’s powerful, heavy trucks were designed to employ the 7.3L Powerstroke diesel engine. The technology (HEUI) used in the diesel engine’s design helped do away with the necessity for a separate injection pump.

High-pressure engine oil generated hydraulic pressure in each injector to forcefully inject low-pressure gasoline in place of the injection pump. The 7.3; Power Stroke was exceptional and powerful enough to handle loads because of the engine’s outstanding characteristics and specifications.
