Mercedes E-Class engine broken? ICE from Europe will solve the problem! In EURO DVIGATEL you can choose and buy any suitable Mercedes E-Class engine.
An engine breakdown can lead any motorist to upset feelings. Overhaul of any engines, including the Mercedes E-Class, is always associated with high monetary costs. By the way, often after a couple of months it turns out that this money was wasted completely in vain - your iron horse is not on the move again. And all because the service masters were not competent enough.
Mercedes E-class: engines
The Mercedes E-class car is one of the most demanded cars of the German concern, the biography of which begins in 1993. The peculiarity of the Mercedes E-Class model is a diverse line of engines with which it was equipped. In all generations of the Mercedes E-Class, both diesel engines, renowned for their economy, and powerful AMG engines were installed.
Engine from Europe: put it on and go!
Repairing the power unit of any car is quite expensive. And if we are talking about such an expensive car as the Mercedes E-Class, then it is worth thinking about the expediency of motor repairs. The right decision would be to buy a Mercedes E-Class engine from Europe - reliable, high-quality, with a high working resource, which will last for many years. Thus, the resuscitation of your car will be limited to the quick installation of the engine and there will be no risks associated with the lack of competence of the repair technicians.
All E-Classes are tested by EURO DVIGATEL specialists for the degree of operability and are accompanied by a full set of related documents.
15.05.2017
One of the most popular Mercedes-Benz series was the E-Class, for which an impressive engine range was created, which included modest 1.6-1.8-liter supercharged units and powerful V8 engines, including AMG variants.
Engine Mercedes-Benz M102 E20 / V20 2.0 l
The M102 E20 inline unit for four cylinders began to be produced in 1980, and it was supposed to replace the archaic M115.
The new M102 family has been designed from the ground up. Along with the 2.0-liter versions, it includes 1.8 and 2.3-liter units, as well as sports 2.5-liter units.
The cast iron cylinder block was re-created, two types of crankshafts were installed. The cylinder head with eight valves and one camshaft did not receive hydraulic valve clearances.
The single-row timing chain drive earned the reputation of an unreliable and quickly out of service part, and in 1987 it was replaced by a double-row chain. The average service life of the timing drive in the M102 E20 motor is up to 150 thousand kilometers.
In 1984, as a result of modernization, the engine received lightweight connecting rods and a crankshaft, as well as hydraulic lifters, other engine mounts and an oil filter.
The disadvantages of the engine include wear on the camshaft, which can only be replaced.
Worn valve stem seals affect high oil consumption.
Engine vibrations occur when the pillows wear.
Also, the M102 is characterized by knocking at idle, which is considered the norm for it.
Engine Mercedes-Benz M111 E20 / E20 ML 2.0 l
Since 1992, the ascent of the M11 E20 engine begins, which became the "ancestor" of the next series of engines for Mercedes-Benz with four cylinders. For this generation of motors, a small cast iron BC, a new crankshaft and a connecting rod-piston group were specially developed.
The cylinder head received 16 valves with a pair of camshafts, hydraulic lifters and electronic fuel injection. Along with atmospheric modifications, compressor versions with the Eaton M62 compressor root were also produced. The resource of the timing chain drive is 250 thousand kilometers.
After 2000, the M111 engine series was improved: the pistons and connecting rods were replaced with an increased compression ratio, the BC received stiffeners. In the cylinder head, the combustion chambers and channels were changed, the fuel system with injectors was modified, the candles and EDZ were replaced and the eco-level was raised to Euro 4.
The disadvantages of the engine include oil leakage due to wear of the cylinder head gasket.
The loss of power and excessive oil consumption is affected by an air flow meter with a resource of 100 thousand kilometers.
Also, the M111 is characterized by noisy work, the fragility of the candles and the pump, the piston skirts quickly wear out and sometimes cracks appear in the exhaust manifold. 3
Engine Mercedes-Benz M271 E18 ML / AL 1.8 L
The M271 power unit has opened another series of in-line 4-cylinder engines, which have been produced since 2002. The M271 E18 motor replaced the entire M111 family at once.
The new unit uses an aluminum BC with cast iron sleeves and a balancing element made of a pair of shafts.
The cylinder head is also aluminum and has two camshafts, four valves for each cylinder, hydraulic lifters and an IFGR system on two shafts.
The cylinder head was used in two versions, in which the intake ports, combustion chambers and camshafts were different.
The supercharger in the motor is an Eaton M65 compressor, and a chain drive is used in the timing.
In 2009, as a result of the improvement, the engine received an IHI Al 0065/0066 turbocharger instead of a compressor, the cylinder head was also modified, and the Siemens SIM4 LDE system became the engine control.
Engine problems include erratic performance caused by a burst crankcase vent hose.
Friction at XX and power loss are caused by coking of valve stems.
Typical for the M 271 E18 is the starting noise that appeared when the chain drive was stretched.
On modernized versions with the EVO mark, the oil level sometimes increases due to the penetration of gasoline. 4
Engine Mercedes-Benz M272 KE / DE 35 3.5 l
The next step in the evolution of Mercedes-Benz V6 engines was the M272 KE / DE 35 unit in 2004. In addition to the impressive 3.5-liter volume, the family included the M272 E25 and M272 E30. Also, volumes of 3.0 liters and 2.5 liters were relevant for him.
The M272 was based on the M112 base with an aluminum cylinder block and a 90 degree camber. Silumin liners received 92.6 mm in diameter, and the new crankshaft had a piston stroke of 86 mm. The pistons themselves are lighter, as are the forged connecting rods and balancer shaft. Aluminum cylinder head with 4 valves per cylinder and 2 DOHC camshafts, with 6mm intake valve stems. The timing drive uses a double roller chain with a resource of 150 thousand kilometers.
In 2011, modifications of the M276 DE35 engine appeared, which were replaced within two years of the M272 on all Mercedes-Benz models.
The main drawbacks of this engine include diesel, combustion Check Engine and errors 1200 and 1208. This is caused by wear of the balance shaft sprockets.
Oil leakage is caused by the unreliability of the plastic cylinder head plugs.
After 70-100 thousand kilometers, you will have to change the intake manifold flaps, but this applies to engines up to 2007. 4+

Mercedes-Benz C 180 W203 Mercedes-Benz C 200 Kompressor W202 Report a bugSelect it and press Ctrl + Enter The central ring road will be built only in 2021, but the fare has already been announced.
One kilometer on the new road will cost the driver 2.5 rubles. Moreover, some sections of the Central Ring Road will be free. Information about the cost is preliminary, the official price list will be released closer to the end of construction.
Now it is not planned to impose fees on drivers in the following areas: in Naro-Fominsk and Odintsovo urban districts. Also, motorists will be able to move around the Central Ring Road in the region of Istra and Solnechnogorsk for free. It was decided to leave the plots free of charge due to the fact that they had already been built before the launch of the project, the builders will only connect new roads to them. A total of 5 separate sections are planned, which will be paid by drivers separately. The total length of the route is 336 kilometers. The list will include the following roads:
Earlier, the construction of the Central Ring Road was stopped due to the fact that the company "Avtodor" did not have enough allocated money. A criminal case has been opened. In September 2019, Jeep cars are sold with a profit of up to 710,000 rubles
In September, FCA RUS presented new conditions for the purchase of Jeep vehicles. The offer applies to the entire model range of the brand. “Recently, there has been consumer interest in the brand on the Russian market. Therefore, September was declared the month of great deals. We want more people to know that Jeep is a legendary brand with high standards of quality, comfort and safety. ” - the company's specialists shared their observations. Thus, buyers of the brand's flagship Jeep Grand Cherokee will be able to get a discount on purchases from 50,000 to 710,000 rubles. A 710,000 ruble discount is available on the Jeep Grand Cherokee Trackhawk, the world's fastest production SUV. For trim levels such as the Jeep Grand Cherokee Overland, the benefit will be 150,000 rubles, and for the Jeep Grand Cherokee Limited - 200,000. Also in September FCA RUS announced a lucrative offer for the legendary Jeep Wrangler SUV. The buyer will be able to buy a bright car with a discount of 200,000 to 550,000 rubles. Conditions apply to 2-door and 4-door versions of the Jeep Wrangler. Side mirrors... Surprising but true. Now many will think about what the rear-view mirrors could interfere with, because they serve for the benefit of the driver. In addition, they are very unpretentious in care and are not expensive. Pay attention to the new Lexus ES, apparently the automaker's engineers have decided to get rid of them now. Instead of mirrors, cameras are installed there, by the way, in Japan, such cars are allowed to move on public roads. So far, this innovation does not apply to other countries, the car will go there with ordinary mirrors.
The engineers assure everyone that the new system allows you to see the picture much better than conventional mirrors, especially in bad weather. The cameras have many advantages, but there is only one minus so far - their cost. Of course, in the future it may become acceptable, but it will still not be on a par with plastic mirrors.
Car radio. Remember the time when radio tape recorders just appeared on the market and took over the domestic auto industry. And those same "Zhiguli", which were constantly tuning and finalizing. Having installed the radio, you could feel like a king, because you could listen to your favorite songs. In modern cars, unfortunately, there is no place for a radio tape recorder, because the transport that is being produced now looks more like a smartphone on wheels. Keys. In the near future, motorists will also refuse keys. Cars will recognize their owners by fingerprints and faces. Agree that it is simple and very convenient. The engine can now be started with a button, the door opens without a key. Recall the first electric starter, it appeared on cars back in 1912 on the Cadillac Model Thirty. Mechanical buttons, selectors, washers. Tesla got rid of all hard buttons. Instead, huge TVs are installed on the dashboard. Other automakers are starting to move to touchpads as well. The car of the future will most likely have only one display that will control all of the vehicle's systems. Do you think it is convenient? In any case, it is inevitable, all this is the future, to which man came himself. |
If such an article had been written twenty or thirty years ago, its message would have been unambiguous - Mercedes power units may not be the most innovative, but there are hardly any more durable motors among competitors.
Today, Mercedes engines use a large number of technical innovations designed to reduce harmful emissions and increase productivity while reducing fuel consumption. Unfortunately, this negatively affected the legendary durability. And if nothing terrible happens to the engine block and head, then malfunctions of the injection system or the supercharger have become something commonplace. Removing defects is usually expensive. It is gratifying that the company quickly learns from its mistakes and quickly gets rid of them.
Gasoline engines 1.6, 1.8, 2.0 M 111 / M 271
Short description:
4-cylinder;
16-valve;
Compressor or turbocharger.
Mercedes has been quite cautious about the topic of supercharging gasoline engines. The Germans relied on a compressor instead of a turbine to provide a smoother increase in power without the unpleasant "turbo lag" effect. The result was presented in 1995 in the form of the M 111 motor with a mechanical compressor driven by a conventional ridge belt. Seven years later, a more modern version of it was shown - M 271.
The most widespread was the 1.8-liter version of the M 271 with a multipoint injection system with varying degrees of boost: from 122 to 192 hp. Some models used a modification with direct fuel injection. It was produced from 2003 to 2005 and developed a power of 170 hp. It can be recognized by the CGI markings.
The drive to reduce capacity led to the creation in 2008 of the 1.6-liter M 271 with compressor. Its use was limited to the C-class W204 and the not very successful CLC. The engine did not have direct injection.
The latest version of the 1.8-liter M 271 with direct injection received a turbocharger instead of a compressor. This motor developed from 156 to 204 hp.
Compressor wear.
For a long time, no one undertook to restore the compressor, offering only to change it. Fortunately, today mechanics have mastered the technology of its regeneration. The cost of such a service is about $ 100-120, including dismantling and installation. The most common compressor malfunctions are rotor bearing wear and clutch failure.
If an annoying howl is emitted during engine operation, then it is time to intervene. But be careful: worn generator bearings make exactly the same sound. You can buy a used compressor disassembled for about $ 300, a clutch repair costs about $ 500, and a brand new unit will cost $ 1,500. Unfortunately, the compressor service life is short - just over 100,000 km.
Timing chain jump.
Timing chain wear, unfortunately, is asymptomatic. She can jump after 60-80 thousand km. It is a pity that a weak single-row chain is used to drive the timing chain. Fortunately, its replacement is not too expensive - around $ 250. The malfunction applies only to M 271 motors.
Oil leaking from the camshaft adjuster.
A typical malfunction of the older generation of M 111 engines. Oil begins to drain from the electromagnets, damaging the electrical harness. Effective elimination of a defect is a laborious task and, worst of all, not always feasible.
Application of engines 1.6-1.8 K / T (M 111, M 271)
These motors were used only in Mercedes cars. They were always located longitudinally in front. All units were assembled at only one plant in Germany.

Output
If you decide on a Mercedes with a compressor, then be sure to choose a newer version of the M 271 and from the very beginning be ready to invest in replacing the timing chain. The advantages of the 1.8 K engine are low fuel consumption. It is better to stay away from older versions of the M 111. Alternatively, you can opt for an atmospheric 2.0 16V or a later 2.4 V6.
Gas engine V6 2.5-3.5 M 272
Short description.
V-shaped 6-cylinder;
24-valve;
Multipoint injection / direct;
For middle class cars and above, SUVs.
The aluminum V-six, codenamed M 272, debuted in 2004. It became the successor to the M 112 V6, which has been in use since 1998. The main changes are the use of the DOHC system (two camshafts in the head) and 4 valves per cylinder instead of 3. A number of modern solutions have been used in the design: an instant change in the valve timing of the intake and exhaust valves, an intake manifold of variable length (i.e. there are dampers). In addition, a balancing shaft is used, which eliminates vibrations caused by a large camber angle of the block. As a rule, in V-shaped engines, an angle of 60 degrees is used (i.e., the full revolution of the shaft divided by the number of cylinders), and in the M 272 engine it is equal to 90 degrees.
Most of the units of the M 272 family have multipoint injection into the intake manifold. In 2006, the version with direct fuel injection debuted. Initially, the engine with the new injection system went to the Mercedes CLS, and is currently used in the E-Class W212 with the designation CGI. In 2010, the successor to the M 276 was presented, however, motors of the M 272 series are still produced today.
Operation and typical faults
The M 272 engine has only one characteristic malfunction. But its elimination is expensive, and the consequences are quite serious. Therefore, recommending a Mercedes V-six is \u200b\u200bquite difficult.
Balancing shaft teeth worn.
The defect has become so widespread that in the United States, owners of faulty cars have filed a lawsuit against the company in the United States, demanding free repair of broken M 272 engines. Wear on the balance shaft gear teeth accelerates chain wear and can cause chain skipping. In addition, as a result of improper operation of the gas distribution system, a dangerous mixture is formed in the cylinders, which leads to the destruction of the catalyst. The malfunction affects all engines with a serial number up to and including 2729 ... 30 468993. Parts to repair are not too expensive (around $ 250), but the procedure requires removing the engine, which will cost around $ 700-1000.

Output
Only one, however, a serious defect casts a shadow on the reputation of the entire family of motors M 272. The engines in which the defect with the balancing shaft has been eliminated are worthy of recommendations. The 5-liter V8 is much more reliable, although the average fuel consumption is 17 l / 100 km.
Diesel engine 200-220 CDI -OM 611
Short description.
4-cylinder;
16-valve;
Common Rail injection system;
Turbocharger;
For middle class cars and above, vans.
In 1997, serious changes took place in the history of Mercedes diesel engines: for the first time, a common rail direct injection engine was used. It was used in the first generation of the Mercedes C-Class station wagon. At the same time, the designation CDI appeared, which is still used today.
The engine received the OM 611 designation. It has 4 cylinders and a working volume of 2.2 liters. The first samples developed 125 hp. and 300 Nm of torque. Compared to its predecessor OM 604, the new unit has received an increase in power by 30%, torque - by 100%, and fuel consumption has dropped by 10%. The injection system operates at a maximum pressure of 1350 bar. Initially, the engines were equipped with a turbocharger with a constant geometry, and since 1999, a supercharger with an adjustable position of the turbine blades has been used. The displacement was also slightly reduced from 2151 to 2148 cm3. The gas distribution system is driven by a chain, there are two shafts in the head, there are four valves for each cylinder.
The OM 611 engine family has several different modifications. In passenger cars (C and E-Class), a unit marked 200 CDI (102-115 hp) and 220 CDI (124-143 hp) was used. In addition, there are 82 and 102 hp variations. for vans Vito, Viano and Sprinter, 122 HP - for Vito and Viano, and 129 hp for Sprinter.
In 2002, with the debut of the E-Class of the W211 series, the 4-cylinder engine of the new generation OM 646 and its derivatives - the 2.7-liter OM 647 and the 3.2-liter OM 648 were introduced. Despite the similar design, about 80% of the components new.
270/320 CDI (OM 612 /OM 613)
The next direction in the development of the OM 611 engine family was the increase in the number of cylinders. The 5-cylinder unit received the designation OM 612, and the 6-cylinder unit was designated OM 613. The first one, marked 270 CDI, developed from 156 to 170 hp, and the second - 320 CDI 197 hp. Also worth mentioning is the 3-liter version 612 OM with 231 hp for the C 30 CDI AMG.
Operation and typical faults
Previous generation Mercedes diesels were renowned for their incredible endurance. Due to the more complex design, sometimes problems arose with the OM 611. It's just that a larger number of elements were more likely to break. Fortunately, serious malfunctions did not occur very often. The cylinder-piston group has high strength. A turbine and a dual-mass flywheel can usually withstand several hundred thousand kilometers. It should be borne in mind that the mileage of the car in advertisements for sale coincides with the real one only in exceptional cases. When choosing a car with CDI, it is necessary to be guided by an assessment of the technical condition of a particular instance.
Difficult launch.
As a rule, it is associated with wear of the high pressure pump, less often with a malfunction of the injection system - nozzles.
Intake manifold.
In many versions of the engine, dampers were installed in the intake system, the closure of which led to an increase in turbulence of the air entering the cylinders, which improved the quality of mixing it with the fuel. Malfunctions of this element lead to a noticeable decrease in engine power and a slower increase in speed.
Thermostat.
CDI engines warm up rather slowly. But if even after several tens of kilometers the motor still does not reach the required temperature, then the thermostat will have to be replaced.
ОМ 611 application
4-cylinder engines were used in class C and E passenger cars, and in minibuses. 5 and 6 cylinders in larger models.
Mercedes C-class W202: 09.1997-05.2000;
Mercedes C-class W203: 05.2000-02.2007;

Mercedes V-class: 03.1999-07.2003;
Mercedes Sprinter: 04.2000-05.2006.
Output
A very good engine for its time - an inexpensive injection system and a durable cylinder-piston group.
In the case of the E-class, instead of the 220 CDI version, you can consider a model with a 270 CDI.
Diesel engine 200-250 CDI -OM 651
Short description.
4-cylinder;
16-valve;
Common Rail;
Turbo or biturbo supercharging.
In 2008, Mercedes introduced a new generation of turbodiesel with the designation OM 651. Initially, the unit had a working volume of 2.2 liters, and since 2011, a 1.8-liter unit has been added to the family. Both diesels have the same cylinder diameter, but the smaller one received a shorter piston stroke - 83 mm instead of 99 mm. The compression ratio in both versions is 16.2: 1.
The engine debuted in its best form with 204 hp. It was installed on C-Class 250 CDI cars. The power unit had a double turbocharging and Delphi piezoelectric injectors. The same solution (biturbo and piezoelectric injectors) was applied somewhat later in the weaker 170-strong version of the 220 CDI. And if there were no particular problems with supercharging, then the injectors caused a lot of suffering. They were so serious that in 2011 a modification of 220 CDI, and since 2012 250 CDI received conventional electromagnetic injectors.
Weaker versions (up to 200 CDI 143 hp) used less troublesome electromagnetic injectors from the very beginning. In addition, these engines had a single variable geometry turbocharger.
OM 651 replaced a wide range of older generation engines - 4, 5 and 6-cylinder, installed longitudinally and transversely, ranging from compacts to vans.
Operation and typical faults
Problems with piezo injectors cast a shadow on the reputation of OM 651. The scale of the flaw was enormous. To eliminate defects during the warranty period, the current production of engines had to be stopped. I must admit that Mercedes conscientiously approached the issue of eliminating the problem. Motors with conventional injectors did not present such problems.
Piezoelectric nozzles.
This is a common malfunction in the early years of production. The engine went into emergency mode while driving. There have been cases of sudden engine stop. Currently, the scale of the problem is small.
Valve train chain.
With an increase in mileage, more and more facts are being recorded about problems with the timing chain. Replacing is troublesome - the chain is located at the back of the engine.
Pump leaking.
Another problem that is gaining momentum with the increase in mileage and the age of cars.
ОМ 651 application
The OM 651 engine has found wide applications ranging from compact models to limousines, sports cars and even vans.

Output
The engine, innovative in many ways, caused Mercedes a lot of trouble. Malfunctions in the 220 and 250 CDI versions further undermined the brand's credibility. Simplified versions are more durable.
Epilogue
Legendary Mercedes engines, in pursuit of power, low fuel consumption and environmental friendliness, have lost their former reliability. The unit itself with a cylinder-piston group is designed for at least 500,000 km of run, but auxiliary equipment fails much earlier, and repairs are very expensive.
The most popular pre-styling engine is the compressor 1.8 M271 Evo, it was installed on the E200 and E250 with 184 and 204 hp forcing. The main problem is the small resource of the timing, chain, stars and tensioner. Often it ended up to 100 thousand, and before the chain jumped, a characteristic noise appeared on the cold and Check Engine. But not everyone was lucky.
- Another problem with the M271 is the leakage of the housing (glass) of the oil filter - it was originally made of plastic, and it cracked. In some cases, replacing the gasket helped, but the correct solution was to replace the body.
- Also, pay attention to whether the oil smells like gasoline and whether there is fogging of oil in the area of \u200b\u200bthe control dipstick, otherwise, most likely, the resource of the crankcase ventilation valve has expired.
- Post-restyled inline-fours 2.0 turbocharged (E200 184 hp and E250 211 hp) - M274 series. In general, a good motor, but with a couple of weak points. The wiring of the variable oil pump valve fails due to constant heating and aggressive environment, which is why the motor can run for some time with oil starvation until the "check" lights up.
- Some of the M274 engines suffered from antifreeze leaks into the oil through the pump (the oil level was above the maximum) and from critical wear of the camshafts (crackling when starting to cold). Both problems were fixed under warranty - just check by VIN whether the car was subject to recall or not.
- On old gasoline V6 3.5 M272 (E300 and E350 until 2011), the problem with the wear of the balance shaft gear and the subsequent violation of the timing phases by the time the W212 was released is a thing of the past. Now the drive resource has increased steadily 150-180 thousand. But the motor remained sensitive to maintenance. So, overheating, detonation from poor fuel, rare oil changes and dust from destroyed catalysts, you can finish off the alumina coating of the cylinders. Therefore, it is mandatory to check with an endoscope.
- When choosing a car with M272, pay attention to oil leaks, this time from under the oil heat exchanger - a family problem.
- Another characteristic problem of the M272 is the wear of the intake manifold flaps, which serves 60-80 thousand, rarely more. If the collector has not changed or been repaired for a long time, then this is waiting for you in the near future.
- Motors V8 M273 (E500) - the same series as the V6 M272. Children's illnesses have been resolved, certain problems remain, and for more or less successful operation, uncompromisingly high-quality service is needed.
- Petrol V6 3.5 new generation (E300 and E350 after 2011) - M276 series. And here, too, children's problems are noticed. In particular, under warranty, the direct injection piezo injectors were changed, as well as timing chain tensioners and dampers (check the VIN, whether it is subject to recall, consult your dealer). A characteristic symptom is a chirp when starting on a cold one.
- The same applies to the M278 series V8 unified with this engine (later E500).
- Diesel engines 2.1 (E200 CDI, E220 CDI, E250 CDI) of different boost from 136 to 204 hp - motors of the OM651 series. Until 2011, they were haunted by the problem of an ultra-low resource of piezo injectors, which were changed under warranty, and together with the control unit. After switching to an electromagnetic motor, it annoyed only with typical diesel problems: EGR, particulate filter, then after 150 thousand injectors, after 200-250 - a turbine and a high-pressure fuel pump, and at the same time the timing chain along with the stars.
- Diesels 3.0 (E300 CDI, E350 CDI) are the V6 of the OM642 series. There were no "early" problems with the injectors here, everything is usually limited to the typical diesel failures described above.
The 200th series appeared much earlier than the E-class itself! Namely, in the back of the W110 - during the life of the second generation of Mercedes cars in the prestigious middle class (then the concept of the E-class did not exist, moreover, as a class of cars, and even more so, as the name of Mercedes). They had a power at the level of 90-105 forces, and with each generation they became more powerful and more powerful, better and better. But they all have several qualities in common - they were two-liter, with four cylinders. And that tradition ended in 2000 in the back of the W210. And in the 211st series it was absent altogether - there the version with the 200 nameplate was only on the 200 Compressor modification, but this motor has always been a much more powerful and sporty derivative of the “just” 200th, so it doesn't count. And most importantly, the 211 had a 1.8-liter engine! The 200s returned again only in 2009, with the appearance of the 212th series - and with several names at once: 200 CGI, BlueEfficiency and just 200. And with the model update in 2013, the Mercedes finally completely decided on the model name and returned the old name to the E200.
