BWM used to be the archenemy of turbocharging (and front-wheel-drive) but today, there really isn't a Bavarian-engineered motor worth our time that doesn't come with at least one turbo, though they also opened the way for performance diesels with their “M” tri-turbo and quad-turbo setups.

TwinPower plays an important role when it comes to efficient and dynamic BMW gasoline and diesel engines. But what is TwinPower Turbo in reality and what does it have to offer to the automotive world?

When it comes to gasoline engines, TwinPower Turbo has three components that apply to anything from three- to twelve-cylinder engines: valvetronic, direct fuel injection and turbocharging. Meanwhile, turbodiesels use common rail injection.

Valvetronic, which stands for variable valve and electronic, is a BMW developed technology that allows to optimize consumption by adjusting the valve lift. The automaker says this technology will singlehandedly reduce fuel consumption by 10 percent while also offering better response.

This mainstream name that people associate with BMWs actually hides behind it a potent technology. The engine's computers offer continuous and precise control over variable intake valve lift. This key system means that when you press the gas pedal, the software system control how much the valves open instead of a regular intake system’s throttle plate.

The system uses another set of rockers that are controlled by an electronically operated camshaft. Because this system can adjust the valves from fully opened to almost closed, the engine doesn't need to rev as much to increase the load.

Valvetronic was first introduced in 2001 on the 316ti 3 Series model and was primarily used on the mass market naturally aspirated motors, like the N42 straight-4 and N52 straight-6. However, it was not used on the twin-turbo N54 straight-6. Instead, the single turbo N55 straight-6 that replaced it it in 2009 offering the same output and the N74 twin-turbo V12 in the top 7-Series were made the switch to Valvetronic. After that, the technology was of course not only in BMW’s big cars, but also in the smaller turbo engines offered on the 1 Series.

BMW uses the name High Precision Injection for its direct injection system with central multi-hole injectors, which gradually replaced port injection systems in the 2000s. Both naturally aspirated and turbocharged BMW engines used piezo injectors. However, BMW’s new N55 six-cylinder turbo engine that has been in use since 2010 in models like the 335i, 535i, X3, X5 and X5 use a solenoid-type injection system developed by Bosch. This system was most likely chosen in order to keep the cars competitively priced (cheap) in the U.S.

The name “TwinPower Turbo” has confused many people as to what lies under the hoods of their BMWs. That's because the name describes both single and twin-turbo engines, despite what the name might suggest.

There was even a class-action lawsuit against BMW for confusing so many people. Calling the TwinPower Turbo a "false twin," the BMW lawsuit said that the Bavarians are guilty of false advertising in attempting to use the word "twin" in the name when the engines only use a single turbo.

TwinPower Turbo originally appeared on twin-scroll, single turbo (launched on the 5 Series Gran Turismo in 2009, followed by E90 335i, 135i, X3 and X5 in 2010) engines starting with the N55 (six-cylinder single turbo replacement for twin- turbo N54) and N74 (6-liter V12 twin-turbo in the 760i and 750Li) in 2009. Twin-scroll turbocharging is basically the core technology for TwinPower Turbo BMWs, but not all of them have it nowadays.

The twin-scroll design starts with an exhaust manifold that separates the exhaust gasses that can interfere with one another, as the gasses flow two through different spirals called “scrolls”. The turbo has two nozzles with different nozzles, one smaller and sharper for better low-end response and another larger and less angled one that comes in at high output requirements. BMW calls its special exhaust manifold Cylinder-bank Comprehensive Manifold or CCM for short.

As we mentioned above, modern BMW TwinPower engines don't necessarily use twin-scroll turbochargers, but they do have a distinct exhaust manifold that catches more exhaust pulses to feed the turbo and thus create more power with less lag.

Three-Cylinder Revolution: B37 and B38 TwinPower Turbo Gasoline and Diesel

A revolution is coming our way from BMW: three-cylinder engines, both gasoline and diesel that can rival much bigger ones. These are built under the modular engine strategy all using the same 500cc cylinders and offer TwinPower Turbo technology in outputs from 120 to 220 horsepower.

Right now, we know that the diesel was codenamed B37 and the gasoline B38, though what their variants and specific outputs are we don’t really know yet. Their first applications are in the hybrid sportscar and more importantly the FWD 1 Series and the family. They are already used by the RWD and in the lower part of the range.

The Best Four-Banger Turbos in the World

Let's start things off small, shall we? In 2004, production started for the straight-4 engine, co-developed with PSA Peugeot Citroen. As a MINI, we know this turbo motor from the Cooper S and JCW, but in 2011, BMW had need of its abilities and came up with the N13 design, which had a different oil filter housing that allowed it to be fitted longitudinally in the RWD 1 Series. The engine was fitted to models like the 101 hp 114i, the 134 hp 116i or the 170 hp 118i model.

Perhaps the most important engine for BMW right now is the so-called N20, a 2.0-liter turbocharged straight-four that also has “TwinPower Turbo” written on its engine cover. This motor has replaced the naturally aspirated straight-6 in “20i” and “28i” BMWs, and is a viable and very efficient alternative.

The N20 displaces 1,997cc and has two stages of output, depending on the model you buy. The 184 PS version is the least powerful and is available on the current X1 and xDrive20i, the F30 320i, 520i and base Z4 sDrive20i. Meanwhile, the top version of this 2.0-liter TwinPower engine makes 245 PS and is used by the F30 328i, 528i as well as the X1, X3 and Z4 models with similar sounding names.

Straight-6 TwinPower Turbo: N55

When you add TwinPower Turbo technology to a straight-six engine, the advantages really become obvious. The N55 twin-scroll engine replaced the more expensive twin-turbo setup of the N54 back in 2009. But both engines pretty much offer the same sort of advantages. Comparable output to BMW's own 4.0-liter V8 is achieved, with a lighter block and more low-end torque, even more tan that found in the E92 M3's high-powered S65 V8.

The basic N55 makes 302 hp (305 PS) and 300 lb-ft (400 Nm) of torque. It's available in cars like the 335i, 135i and all the SUV models. There’s an even more power version called the N55HP, which makes 315 hp (320 PS) and 330 lb-ft (450 Nm) of torque, used by high-end models like the 640i, 740i and even the sporty M140i hyper hatchback.

The engine made its debut with the 5 Series GT in 2009. Equipped with this upgraded version of the six-cylinder, the BMW 535i Gran Turismo is said to be able to accelerate from a standstill to 100 km/h (62 mh) in 6.3 seconds, with a top speed limited to 250 km/h (155 mph). In terms of fuel economy/autonomy, BMW's 535i GT sits at 8.9 liters/100 kilometers or 31.7 mpg, while CO2 ratings climb at 209 grams per kilometer.

twinturbo and biturbo what is the difference and what are the differences

Contrary to the beliefs of some "experts", the name of the system biturbo or twinturbo do not display the turbine operation scheme - parallel or sequential (sequential).

For example, in a Mitsubishi 3000 VR-4, the turbocharging system is called TwinTurbo (twinturbo). The car has a V6 engine and it has two turbines, each of which uses the energy of the exhaust gases from its three cylinders, but they blow into one common intake manifold. U, for example, German cars there are systems similar in working principle, but they are not called twinturbo (twinturbo), but BiTurbo (BiTurbo).
On the Toyota car The inline-six Supra has two turbines, the turbocharging system is called TwinTurbo (twinturbo), but they work in a special sequence, turning on and off with the help of special bypass valves.
The Subaru B4 car also has two turbines, but they work in series: at low speeds, a small turbine blows, and at high speeds, when it fails, a second larger turbine is connected.

Let's take a look at both systems now. bi-turbo (biturbo) and twinturbo (twinturbo), or rather, what they write about them in “these your Internets”:

bi-turbo (biturbo) - a turbocharging system, which consists of two turbines connected in series. In system biturbo two turbines are used, one small and the other larger. A small turbine spins faster, but at high engine speeds, a small turbine cannot cope with compressing the air and creating the right pressure. Then a large turbine is connected, adding a powerful charge of compressed air. Consequently, the delay (or turbolag) is minimized, and a smooth acceleration dynamics is formed. Systems biturbo not a very cheap pleasure and are usually installed on high-end cars.
System biturbo (bitrubo) can be installed as on a V6 engine, where each turbine will be installed on its own side, but with a common intake. Either on an in-line engine, where the turbine is installed by cylinders (for example, 2 for a small and 2 for a large turbine), or sequentially, when on exhaust manifold First, a large pipe is installed, and then a small one.

twin turbo (twinturbo) - this system is different from bi-turbo in that it is not aimed at reducing turbo lag or equalizing acceleration dynamics, but at increasing performance. In systems twinturbo (twinturbo) two identical turbines are used, respectively, the performance of such a turbocharging system is more efficient than systems with a single turbine. In addition, if you use 2 small turbines, similar in performance to one large one, you can reduce unwanted turbolag. But this does not mean that no one uses two large turbines. For example, a serious dredge might use two large turbines for even more performance. System twin turbo can work both on V-shaped motors and on in-line ones. The sequence of turning on the turbines can vary, as well as on biturbo systems.

In general, for even more fun, no one bothers you to stick 3 (!) Turbines or more at once. The goal is the same as for twinturbo. I must say that this is often used in drag racing and never on stock cars.

Engine: a new benchmark for efficiency and dynamism.
BMW X models offer their own distinctive interpretation of typical BMW driving pleasure. The BMW X1 xDrive28i combines this special driving experience with an efficiency that is unmatched in this performance class. As a result, this new BMW X1 model offers a sporty power delivery of a kind that has been previouslyconfined to six-cylinder engines - but combines it with outstanding fuel consumption and emissions performance.

It's all down to the latest generation 2.0-liter four-cylinder Gas engine, which sets new standards with various innovative technologies. The powerhouse BMW X1 xDrive28i"s achieves the twin goals of BMW EfficientDynamics in impressive style: it constantly raises the bar for driving pleasure, while at the same time reducing fuel consumption and emissions.

With a displacement of 1997 cc and world-exclusive BMW TwinPower Turbo technology including twin-scroll turbo, High Precision Injection,
Double-VANOS and VALVETRONIC, it delivers a maximum output of 180 kW/245 hp. at 5000 rpm - 55 kW more than the previous top power
BMW 2.0 liter petrol engine.

Debut: First use of the BMW TwinPower Turbo in a four-cylinder engine.

BMW Twin Power Turbo technology gives the new four-cylinder engine the kind of power that naturally aspirated engines can only achieve by
more cylinders and significantly more displacement. Four-cylinder engine with an all-aluminum crankcase, including motorsport-derived bottom plate, is
lighter and more compact than a six-cylinder engine of equivalent power. These are direct benefits to the efficiency of the BMW X1 xDrive28i as well,

The new engine offers more torque, too, than the previous naturally aspirated engines. Rated torque of 350 Nm, which comes to the stream in just
1250 rpm provides a very good budget response. Energetic power delivery, only with slightly higher idle move, is a very seductive feature of this new engine,
and the power rises steadily all the way to the top of the load range. New BMW X1 xDrive28i has 0 to 100 km/h (62 mph) sprint time
6.1 seconds (6.5 seconds from automatic transmission gears). These improvement times are 0.7 seconds and 0.3 seconds respectively on those for
The previous model with a six-speed automatic transmission. The new BMW X1 xDrive28i hits a top speed of 240 km/h (149 mph).

Turbocharger twin-scroll system. The exhaust streams leaving the two pairs of cylinders are kept completely separate as they pass through
Exhaust manifold and turbocharger, taking the spiral to the turbine wheel. This configuration results in very low exhaust emissions at low
engine speed, and allows the energy of the exhaust pulses of the gas to be optimally controlled and translated into powerful rotation of the turbine blades, without
delay response. The result is instant throttle response and typical fastrevving BMW Performance.

More dynamic characteristics plus reduced emissions thanks to VALVETRONIC, dual VANOS and direct fuel injection.

Fully integrated cylinder head VALVETRONIC variable valve timing control system, and Double-VANOS variable intake and exhaust valve timing, have a further positive impact on the development of the power industry. The BMW X1 xDrive28i engine has assembled intake and exhaust valves and the latestgeneration VALVETRONIC system which is still faster action thanks to
optimized stepper motor with built-in sensor.

The patented BMW VALVETRONIC system with variable smoothly inlet valve control lifts dispenses with throttle valve systems of typical early generations of engines. Instead, the mass of air into the combustion chamber is controlled within the engine, resulting in a significantly faster response. Pumping losses have been kept to a minimum, making the engine more efficient.

The new engine is extraordinarily high efficiency, for a turbocharged unit, also up to a High Precision Injection petrol direct injection system. The hotel is located between valves, electromagnetic injectors Max pressure injection up to 200 bar precisely control fuel delivery. Fuel is injected in close proximity to the spark plug, resulting in a clean and homogeneous combustion. The cooling effect of the injected fuel also results in a higher compression ratio than on naturally aspirated turbocharged engines. The result is a further improvement in efficiency.

The efficiency theme continues with a computer controlled oil pump and an on-demand electric coolant pump. In addition, the new BMW X1 xDrive28i is listed as standard with a six-speed transmission mechanical box with Auto function start-stop. This system automatically shuts off the engine when the vehicle is stopped at an intersection or sits in stationary traffic in order to prevent unnecessary idling and wasteful fuel use.

New engine technology and extensive, standard BMW-equipped EfficientDynamics features achieve an exceptionally good balance between performance and fuel consumption. The new BMW X1 xDrive28i has an average EU test cycle fuel consumption of 7.9 l/100 km (35.7 mpg IMP), a 16 percent increase on the outgoing model. CO2 emissions with a capacity of 183 grams per kilometer.
