From 2007 through 2015, the BMW 335i was a viable option. The N54 and N55 were the 335i’s two main engines. The two engines each have a 3.0L inline-6 turbocharger. The N55 engine only has a single twin-scroll turbo, whereas the previous N54 engine uses two turbos. Despite having different turbos, the majority of BMW 335i vehicles produce the same 300 hp and 300 lb-ft of torque. In this post, we analyze the horsepower and torque of the 335i according to various periods and talk more about the cars’ potential horsepower.

N54 vs. N55 BMW Engine
Most of what we’re going to do is just give a brief summary and some further resources. The changes between the N54 and N55 engines have been covered in a couple of our articles. Both the 2011–2013 335is and the 2007–2010 335i vehicles contain the N54. The 2011–2015 BMW models use the N55 engine.
The presence of turbochargers is one of the most obvious changes. While the N55 receives a single twin-scroll turbo, the N54 has a real twin turbo arrangement. It is generally acknowledged that the N55’s performance decreased from that of the N54. Comparing the N55 to the N54, reliability did increase. Many of the N54’s early problems have been overcome as of 2020. Both the N54 and N55 are not thought to be dependable vehicles. The N55, however, tends to be more dependable.
With the N55 engine alone, there is one more obvious distinction. Pneumatic wastegates (PWGs) are a feature of the early N55 versions (2011–2013). This indicates that ALL N55 335i E-chassis vehicles are PWG. BMW switched to an electronic wastegate (EWG) system in the middle of 2013. The EWG variants have a little bigger turbo and an all-around superior wastegate design. The EWG N55s are therefore more appropriate for mods than the PWG N55. To learn more about EWG vs. PWG, go here. According to potential for performance:
- N54
- N55 EWG
- N55 PWG
The N54 is probably your best option if you’re buying a 335i primarily for tuning and modding. The N55 PWG models are often the least capable, followed by the N55 EWG models.
The revised, one turbo-less 335i has lost one turbo. Does this portend the end of the coupe?
It is the BMW 335i coupe, however it has one less turbo. This switch to a single blower gives me the sneaking notion that future M models will be distinguished by having twin turbos. BMW itself has stated that current M3 will be the final naturally aspirated model, with the following featuring a turbocharged six. We already know that the upcoming M5 will feature the X6M’s twin turbo V8. That’s all for now; we’ll talk about it later. The updated 335i is a part of the entire coupe and cabrio range’s mid-life refresh.
What model BMW has dual turbos?
From 2006 through 2016, BMW developed the N54, a twin-turbocharged straight-six petrol engine. Since the 1986 discontinuation of the BMW M106’s restricted manufacturing, it is BMW’s first turbocharged gasoline engine that is mass produced. The N54 was introduced in the 335i model of the E90/E91/E92/E93 3 Series lineup during the 2006 Geneva Motor Show.
The N54 started to disappear after the 2009 debut of its BMW N55 replacement. The E89 Z4 roadster, which was built until 2016, is the last vehicle to be powered by the N54.
Although the N54 does not exist in a BMW M configuration, it is used in the 1 Series M Coupe, 135iS, Z4 35iS, and 335iS vehicles.
How old is the twin-turbo BMW 335i?
BMW produced a 3L N54B30 inline-6 twin-turbo engine with 302 horsepower and 295 pound-feet of torque from 2006 until 2009. For the 2010–2013 models, a N55B30 engine was used in the car. This indicates that the performance of every 335i model is quite comparable. Upgrades to the horsepower require a 335is.
BMW produced the straight-six gasoline engine with twin turbochargers known as the N54 from 2006 until 2016. It was the company’s first mass-produced design of its kind.
Additionally, it was BMW’s first gasoline turbocharged engine since the M106’s production ceased in 1986. This design for the E90 series was introduced with the 335i.
The N54 was gradually phased away in 2009 to make room for the N55. The more recent 335i automobiles on the road have the upgraded engine.
The N54 was such a superior engine that it was named the International Engine of the Year five times in a row. Additionally, it would receive three consecutive “10 Best Engines” awards from Ward’s.
Drivers may gain 20 HP more from the 335is if they upgraded to it. To get the desired results, a supercharged N54 would be needed.
The engine is distinctive because it uses piezo injectors for direct injection. Instead, the technology uses solenoid-type injectors if you have a 335i with the N55 engine.
The majority of analysts concur that the N54’s ratings fall short of its promise, particularly when coupled with the 335i. It delivers power consistently, produces a pleasing growl, and has minimal turbo lag.
Which BMW 3 series is turbocharged?
Two powerful and smooth gas engines are available in the 3-series. The 2.0-liter turbocharged four-cylinder in the 330i produces 255 horsepower and 295 pound-feet of torque, but it seems like it has even more power. The 3.0-liter inline-six turbocharged engine and 48-volt hybrid system in the M340i produce a combined 382 horsepower and 369 pound-feet of torque. A turbocharged 2.0-liter engine and an electric motor are combined in the 330e plug-in hybrid to produce 288 horsepower and 310 pound-feet of torque. We enjoy the Xtraboost feature, which produces a surge of power that feels like a little injection of nitrous, and the way the plug-in engine harmoniously balances the gas and electric components. A intuitive and incredibly smooth eight-speed automatic transmission and rear-wheel drive are included with each powerplant. For a fee, you can drive all four wheels, but no amount of money can get you a manual transmission. The base suspension, the tauter M Sport tune, or the Dynamic Handling package with its adaptive dampers are the options available to buyers for the 3. The four-cylinder Bimmer triumphed in a comparative test against other sports sedans, demonstrating its value. We praised its capacity to change from being calm and elegant to being incisive and fun. In a two-car comparison, the 330i defeated the exquisite Alfa Romeo Giulia, solidifying its position as the best in its class. Our long-term M340i, with its roaring six-cylinder and amazing body control, further demonstrates the nameplate’s return to form.
Is the 335i a twin-scroll or twin-turbo vehicle?
In a first for turbocharged engines, this one-of-a-kind engine combines a twin-scroll TwinPower Turbo, High Precision direct fuel injection, and BMW’s Valvetronic variable intake technology to improve the engine’s ability to “breathe.” The end result is almost no turbo lag and one of the highest fuel efficiency ratings in its class.
At a redline of 7000 rpm, the 335i TwinPower Turbo reaches its maximum output of 300 horsepower. At 1300 rpm, the maximum torque of 300 lb-ft almost immediately begins to flow. Up to 5000 rpm, it keeps shoving you back in your seat. You effortlessly shatter all expectations in just 5.3 seconds as you comfortably pass 60 mph.
What distinguishes a BMW 335i from a 335is?
The 335is is essentially a slightly modified version of the 335i. However, we wouldn’t mind if the 335i got a little hotter. Although the 335i received an engine upgrade for 2011, switching from dual to a single twin scroll turbocharger, the 335is retains the engine from the 2010 3-series.
Which issues does the BMW 335i have?
One of the most prevalent 2007 BMW 335i problems is engine troubles. Some vehicles from this model year frequently experience turbo failure, low gas mileage, rough running, and engine overheating. Some owners claim that their vehicle automatically enters limp mode when it overheats.
N54 has only one turbo?
The “cold-side” of the turbocharger is referred to as the compressor wheel. It compresses the new air that enters the turbo, as the name implies. At the inducer, compressor wheels are sized in millimeters. Some people will additionally mention the exducer’s size individually. Both are significant, but the inducer’s size matters more. We won’t waste time discussing this because it may be a lengthy topic. If you want to understand more, look up inducer and exducer on Google; it is explained there far better than we could.
So let’s get back on course. The compressor has a millimeter scale. Common N54 single turbos include the Precision Turbos 6266 or 6466. The first two digits, 62mm and 64mm, respectively, indicate the dimensions of the compressor wheels.
How many horsepower is a 335i?
Here is a look at the new 3-Series Coupe, despite the fact that Canadian details and pricing are not yet available.
Twin turbocharged 3.0 liter inline-6 power the 335i Coupe in Europe. At under 1,900 revolutions per minute, this amazing engine generates 306 horsepower and 295 lb-ft of torque. BMW claims that the 0-100 km/h sprint takes just 5.5 seconds, and the car’s controlled top speed is 250 km/h. Fuel consumption is claimed to be as low as 9.5 L/100 km despite that performance. When the new coupe arrives on sale here, let’s hope it will make the journey to our shores.
The 3-Series Coupe will be offered with two additional gasoline engines and two additional diesel engines when it is introduced in Europe.
With 272 hp and 232 lb-ft of torque, the 330i Coupe can reach speeds of 250 km/h and 0–100 km/h in 6.1 seconds.
The 325i Coupe has a 218 hp and 184 lb-ft of torque, can reach a top speed of 247 km/h, and only uses 8.4 liters of fuel per 100 kilometers. It can sprint from 0 to 100 km/h in 6.9 seconds.
Regarding the diesel variants, the 335d Coupe, powered by a 3.0-liter inline-6 with dual turbochargers, generates an astounding 427 lb-ft of torque at just 1,750 rpm in addition to 286 horsepower. 250 km/h is the maximum speed that can be reached from 0-100 km/h in 6.1 seconds. The fuel usage is 7.5 L/100 km.
If that sounds like too much, a 3.0-liter diesel engine with normally aspirated combustion is also an option. It has 231 horsepower and 369 lb-ft of torque, and it can accelerate from 0 to 100 km/h in 6.6 seconds. The 330d Coupe can go up to 250 km/h and only uses 6.5 liters of fuel per 100 kilometers.
For the Coupe’s extra-large brake discs, which call for 17-inch wheels, BMW is the first automaker to provide a continuous brake pad wear indicator. Additionally, xDrive will be available on the new 3-Series Coupe for the first time.
According to BMW, “a really fascinating driving experience is further ensured by rear-wheel drive, optimized weight, harmonious axle load distribution, and the most advanced suspension in the segment.”
When did the 335i get the N54?
The 335is were reserved for last, and the years were combined because there were no significant modifications from 2011 to 2013. This 335i was a “luxury” model and equipped with a DCT rather than the N54 335i’s regular auto transmission. Additionally, only the E92 coupe and E93 convertible body types are offered. The 335is utilizes the older N54 engine as opposed to the conventional 335i of the same years. By 2011, HPFP difficulties had been largely overcome. Fuel injector problems are still rather common despite being a more recent index. An oil cooler is standard on all BMW 335is models.
The 335is is perhaps the most sought-after and uncommon N54-powered vehicle after the 1M. As a result, they are often quite a bit more expensive when compared to older N54s or N55 335i vehicles from the same year.
How long is the 335i’s lifespan?
When properly maintained and driven cautiously, the BMW 3 Series can endure between 200,000 and 250,000 miles. It will last roughly 13 to 17 years if you drive 15,000 miles per year before needing expensive and unnecessary repairs.
Which 335i year is the most dependable?
A few strong model years are available if you want a more dependable BMW 335i. These models have fixed the errors and inconsistencies in the first design. Additionally, they have no difficulties with any of the modifications and other design advances.
The following is a list of the most dependable BMW 335i model years:
2010 2012 2015 2016
Four models may not seem like much for a car that has been manufactured since 2007, but you shouldn’t let that stop you from purchasing a BMW 335i, especially if you can do it in the current model year.
This is so because all of these model years have exceptionally low complaint rates and frequently enjoy high consumer favorability. In general, they perform better than many rival vehicles, which is fantastic news for BMW devotees.
