The TwinPower Turbo and the TwinTurbo Power are the two different varieties of twin turbo BMW engines. You’ll discover an exhaust manifold divided into two headers in both possibilities. One turbo unit and two exhaust down tubes make up the TwinPower Turbo. Two turbos and two exhaust down tubes are part of the TwinTurbo Power.

What distinguishes TwinPower Turbo from TwinTurbo Power fundamentally?
Based on firing order, the exhaust manifold in both designs is evenly divided into two headers. The TwinPower Turbo, often known as the dual scroll turbo, is a single turbo powered by two exhaust down tubes and two pairs of alternating cylinders. Each of the two exhaust down tubes on the Twin Turbo Power’s two turbos is fed. Refer to the illustration below to see how the TwinPower Turbo technology looks. The following example is from a 4-cylinder engine, but the same concept may be used with 6-, 8-, and 12-cylinder engines.
Now that the fundamental concept has been clarified, we can further discuss why BMW shifted to the TwinPower design and its benefits over the Twin Turbo Power design.
BMW uses twin turbo, right?
The heart of every BMW is an innovative petrol and diesel engine featuring BMW TwinPower Turbo technology. They blend cutting-edge turbocharger technology, fully variable performance control, and the newest injection technologies.
How does the BMW twin turbo function?
The two turbochargers are often positioned one next to the other in twin turbo technology. By forcing more air into the combustion chamber, these parts combine to increase your engine’s power and fuel efficiency.
Twin Power Turbo—does this refer to two turbos?
BMW created its ground-breaking TwinPower Turbo technology on the basis of the twin-scroll principle, as alluded to in the first sentence. In essence, the name tells it all, yet even if it’s obvious, many people don’t find it to be that simple.
First off, despite the fact that both use two turbochargers, a widespread misunderstanding is that twin turbo = biturbo, which is rarely the case. Another misconception is the idea that TwinPower Turbo really refers to a twin turbo setup, which is untrue.
To further explain, let’s begin with the following definitions:
- Two turbochargers are used in tandem with each other in twin turbo technology.
- Biturbo also uses two turbochargers, but they are divided equally on either side of the cylinder bank.
- A single turbocharger with two scrolls is the foundation of the BMW TwinPower Turbo.
- Two turbochargers are used by BMW TwinTurbo Power (yes, this variant also exists).
- Don’t confuse TwinPower Turbo with TwinTurbo Power because they are different.
It seems simple, huh? It sort of is. An exhaust manifold that is properly constructed and what is known as a divided intake turbine are both components of BMW’s TwinPower Turbo technology. The last part is extremely important since it aids in properly aligning the cylinders so that exhaust gas can be directed independently on a single scroll.
As you may remember, the TwinPower Turbo is now installed on BMW engines with either four or six cylinders, depending on the fuel type being used. In inline-four applications, the first and third firing cylinders are paired on one scroll, while the second and fourth firing cylinders are coupled on the second scroll.
The combination order for inline-six engines is commonly 1-3-5 on one scroll and 2-4-6 on the other scroll. Given the heated inner V architecture of the BMW V8 units (the N63/S63 generation), the requirement for greater power led to the adoption of twin turbo, or two turbochargers combined. And indeed, despite not having a clear name, the 8-cylinder engine’s turbocharging system is known as BMW TwinTurbo Power.
Moving on to TwinPower Turbo, which utilizes the twin-scroll concept, there are a number of advantages over single-scroll turbochargers.
- due to the balanced pairing of cylinders depending on firing order, the boost response is proper and swift.
- Continual recirculation of exhaust gases via the twin-scroll engine’s exhaust system enables consistent, uninterrupted power output at all engine speeds.
- the turbocharger wheel is fed with as much pulse energy as possible.
- increased running effectiveness and turbocharging unit life
- considerable reduction in fuel use and turbo lag
- a better low-end power delivery that is comparable to twin turbo engines
- measurable progress in lowering pumping losses
Other parts have been created to improve the balance and smoothness of the engine’s operation in order to exploit the advantages of the BMW TwinPower Turbo. The centrifugal force pendulum included into the dual-mass flywheel operates to avoid any irregular engine rotations, which are prone to occur at low rpm. The vertically offset balance shafts correct the vibration optimally.
Does twin turbo correspond to twofold power?
The TwinPower Turbo and the TwinTurbo Power are the two different varieties of twin turbo BMW engines. You’ll discover an exhaust manifold divided into two headers in both possibilities. One turbo unit and two exhaust down tubes make up the TwinPower Turbo. Two turbos and two exhaust down tubes are part of the TwinTurbo Power.
Which BMW model has a twin turbo V8?
From 2008 till the present, the twin-turbocharged V8 petrol engine known as the BMW N63 has been manufactured. The N63’s “hot-vee” architecture, with the turbochargers housed inside the “V” of the engine, makes it the first production automobile engine in the world. Additionally, it is BMW’s first V8 turbocharged engine.
A naturally aspirated V8 engine, the BMW N62 was succeeded by the N63, which made its debut in the 2008 X6 xDrive50i.
How many horsepower can a BMW get from a twin turbo?
180 hp and 280 lb-ft of torque are produced by the 2.0-liter, 4-cylinder, TwinPower Turbo Diesel engine of the BMW starting at 1,750 rpm. With its 8-speed automatic transmission, it can easily go from 0 to 60 mph in just over seven seconds.
What BMW models have twin turbo?
We’re not only referring to mpg numbers when we say that automakers have mastered the art of getting more mileage out of their engines in recent years. German luxury manufacturers and their in-house speed shops frequently employ a powertrain approach that decreases the number of engine configurations and displacements in a company’s range while boosting the number of variations of those fundamental engines. The objective is to accommodate a variety of applications without starting from scratch, including sedans, crossovers, sports cars, and factory hot rods. Consider 2.0-liter four-cylinder engines with a range of 200 to 400 horsepower and V-8s with a range of 400 to 600 horsepower. This strategy controls the expense and complexity of engine development as well as manufacture.
Such power changes can be caused by adjusting boost levels and software in the era of computer-managed turbo engines, as in the Aston Martin DBS Superleggera. Or not. Consider the 445-horsepower N63B44O1 in the 2018 X5 and the 617-horsepower S63B44T4 in the 2019 M5 Competition as the least and most potent iterations of BMW’s twin-turbo 4.4-liter V-8. With the same size and stroke, compression ratio, valve diameters, and cam profiles, BMW manufactures both in its Munich facility. But they are not at all alike.
A 328i is a twin turbo, right?
The 2.0-liter, four-cylinder TwinPower Turbo engine used in the 328i generates 240 horsepower between 5,000 and 6,000 rpm and 255 foot-pounds of torque between 1,250 and 4,800 rpm. TwinPower is BMW’s twin-scroll turbocharger system.
What is a 4-cylinder BMW twin-turbo engine?
Lightweight and quiet, it features BMW’s award-winning High Precision Direct Injection, Valvetronic, and double-VANOS technologies. 2.0-Liter, TwinPower Turbo Inline 4-Cylinder Engine, 240 horsepower Its exceptional fuel efficiency matches its sporty performance, getting you farther on every gallon of gas.
What distinguishes a turbocharger from a double turbocharger?
Essentially, these phrases have the same meaning. A car’s “twin turbo” or “bi-turbo” designation denotes the presence of two turbochargers in the engine.
The preferred terminology is different across various auto manufacturers. In V6, V8, or V12 engines, two turbochargers are frequently employed. A single turbocharger can be used for each bank of cylinders, which has several benefits for packing and efficiency.
For the majority of four-cylinder engines, one turbocharger is adequate. It is occasionally utilized in inline-6 and V6 engines as well.
You may have also heard the phrase “twin-scroll turbocharger”. Now, this doesn’t specify how many turbos were employed. It describes the kind of turbocharger instead.
When exhaust gases approach the turbine area of a turbocharger, they travel in a spiral pattern known as the “scroll.”
The exhaust tracts of consecutively firing cylinders are isolated all the way to the turbine’s mouth in order to eliminate gas-flow interference caused by the exhaust pulses.
The exhaust gases continue to maintain separate routes as they enter two distinct scrolls within the turbocharger unit’s body, giving rise to the phrase “twin-scroll.”
Twin-scroll turbochargers allow for somewhat more powerful tuning of engines than single-scroll models while also providing higher levels of gas-flow efficiency and less turbo lag. Many of the most recent engines employ twin-scroll turbochargers.
So keep in mind that twin-turbo and bi-turbo are interchangeable, but twin-scroll turbo is not.
Are twin turbos preferable to single turbos?
Compared to single-scroll turbochargers, twin-scroll turbochargers are superior in almost every manner. The exhaust pulses are split by two scrolls. For instance, cylinders 1 and 4 may feed to one turbo scroll while cylinders 2 and 3 may feed to a different scroll on a four-cylinder engine with the firing order 1-3-4-2. Why is this advantageous? As the piston reaches bottom dead center and the exhaust valve begins to open, let’s suppose that cylinder 1 is nearing the conclusion of its power stroke. However, there is some overlap as cylinder 2 completes the exhaust stroke, closes the exhaust valve, and opens the intake valve. Since both exhaust valves are briefly open in a conventional single-scroll turbo manifold, less pressure will reach the turbo and less air will be pulled in by cylinder 2, which will cause interference with the exhaust pressure from cylinder 1. In order to solve this issue, the scrolls are divided.
- The exhaust turbine receives more energy, which increases its power.
- Based on the various scroll designs, a larger RPM range of effective boost is feasible.
- There is additional tuning flexibility because higher valve overlap is allowed without impairing exhaust scavenging.
- need a certain engine configuration and exhaust design
- Compared to standard single turbos, cost and complexity.
Twin turbo: Does it use extra fuel?
For instance, Consumer Reports came to the conclusion that smaller, turbocharged engines often get worse gas mileage than larger engines without them. In comparison to their larger, naturally aspirated counterparts, Ecoboost Ford Fusions with turbocharged, four-cylinder engines consumed more fuel in the testing.
