What engine size is W211?

The Mercedes-Benz W211 is an executive sedan manufactured by German automaker Mercedes-Benz between 2002-2009. The W211 represents the third generation E-Class model and came in both sedan and station wagon body styles.

The W211 E-Class was launched in 2002 to replace the previous W210 generation that had been produced since 1995. The W211 brought a range of improvements over the preceding W210 including a more streamlined exterior design, increased interior room and updated engine options. It continued the E-Class tradition of providing a comfortable and luxurious driving experience paired with powerful engine performance.

Gasoline Engines

According to Specs for all Mercedes Benz E Class (W211) versions, the W211 E-Class was available with the following gasoline engine options:

E 200 Kompressor – 1.8 L supercharged I4, 163 hp (2002-2006)
E 240 – 2.6 L V6, 177 hp (2002-2006)
E 270 CDI – 2.7 L V6, 170 hp (2002-2006)

E 280 – 2.8 L V6, 186 hp (2002-2006)
E 320 – 3.2 L V6, 221 hp (2002-2005)
E 350 – 3.5 L V6, 272 hp (2006-2009)

E 500 – 5.0 L V8, 302 hp (2002-2006)
E 550 – 5.5 L V8, 382 hp (2006-2009)

The gasoline engines ranged from 1.8L 4-cylinder units in the base E 200 Kompressor to powerful 5.5L V8s in the top E 550 model. Mercedes offered both V6 and V8 layouts, with horsepower output between 163 hp to 382 hp depending on the engine and model year.

Diesel Engines

The W211 E-Class offered several diesel engine options during its production run from 2002-2009. The main diesel engines available were:

2.2L I4 – Two versions were offered: the 200 CDI with 134 hp and the 220 CDI with 150 hp (Wikipedia)
3.0L V6 – The E280 CDI produced 190 hp, while the more powerful E320 CDI made 224 hp (Ultimate Specs)

5.0L V8 – Only available on the E500 CDI, this 258 hp turbocharged diesel V8 was exclusive to the W211 (FCP Euro)

These turbocharged diesel engines provided a good balance of power, efficiency, and reliability for E-Class buyers looking for an alternative to gasoline engines.

Smallest Engine

The smallest engine available in the Mercedes-Benz W211 E-Class was the 1.8-liter M271 inline-4 gasoline engine. This 4-cylinder motor had a displacement of 1796 cc and produced 143 horsepower at 5500 rpm and 184 lb-ft of torque at 4000 rpm (Mercedes-Benz M271 engine – Wikipedia, 2023).

The 1.8L engine was offered on lower trim models like the E200 and E200 Kompressor. It provided adequate power for daily driving needs, but was considered underpowered by some, especially when mated to an automatic transmission. This petite powerplant focused more on fuel efficiency than performance.

Though modest in size and output, the 1.8L inline-4 gave the entry level W211 respectable acceleration. This smallest engine struck a balance between economy and drivability. It allowed Mercedes to attract buyers looking for the luxury and refinement of an E-Class without the thirst for fuel or maintenance costs of a larger six or eight-cylinder motor.

Largest Engine

The largest engine option available in the Mercedes-Benz W211 E-Class was the 6.3 liter AMG V8 engine. This high-performance engine was introduced in 2006 on the E63 AMG model (Wikipedia, 2022).

The 6.2 liter M156 V8 engine displaced 6,208 cc and produced 507 hp at 6,800 rpm with 465 lb-ft of torque at 5,200 rpm (Wikipedia, 2022). This powerful naturally aspirated V8 allowed the E63 AMG to accelerate from 0-60 mph in just 4.3 seconds, with an electronically limited top speed of 155 mph (Wikipedia, 2022).

Key features of this hand-built AMG engine included an all-aluminum block and heads, a staggered ignition firing order, and variable valve timing on the intake and exhaust camshafts. The engine was mated to a 7-speed automatic transmission and had enlarged brake discs and calipers to handle the power increase over standard E-Class models (Wikipedia, 2022).

In summary, the largest engine offered in the W211 generation E-Class was the high-revving 6.2 liter V8 in the E63 AMG model, providing over 500 horsepower in a luxurious midsize sedan package.

– Advanced common rail diesel engines with piezo inline injection, optimized combustion, and lower particulate emissions.

– Introduction of Bluetec emissions control technology for diesel engines to reduce nitrogen oxides.

– Improved engine mounts and sound insulation for reduced noise and vibration.

Through continuous innovation in engine design, Mercedes-Benz has pushed the boundaries for performance, efficiency, and technology in the automotive industry. The W211 E-Class demonstrated the latest advancements in Mercedes’ renowned engineering.

Fuel Efficiency

Fuel efficiency varies across the different engine options available in the Mercedes-Benz W211 E-Class. According to Car Emissions, the W211 models achieve an average fuel consumption of 34.2 mpg or 8.6 liters/100km based on 87 models tested

Specifically, the E200 Kompressor model with a 1.8 liter 4-cylinder gasoline engine gets around 20 mpg city and 29 mpg highway per Mercedes-Benz specifications (https://www.ultimatespecs.com/car-specs/Mercedes-Benz/1377/Mercedes-Benz-E-Class-(W211)-200-Kompressor.html). Real world fuel economy for this engine is generally a bit lower.

The E280 model with a 3.0 liter V6 gasoline engine achieves approximately 18 mpg city and 25 mpg highway based on Mercedes-Benz estimates. However, actual fuel efficiency depends heavily on driving style and conditions.

On the diesel side, the E320 CDI with a 3.2 liter turbodiesel V6 sees fuel economy around 22 mpg city and 33 mpg highway per Mercedes-Benz. Many owners report getting 35-40 mpg or better with conservative driving.

Overall, fuel efficiency can vary significantly depending on engine, transmission, driving style, conditions, mileage, and maintenance. But generally, the 4-cylinder gasoline, 6-cylinder gasoline, and diesel engines offer progressively better fuel economy.
