3. Third Generation (W204: 2007–2014)

Balance Between Performance & Efficiency

The W204 offered a complete redesign and introduced BlueEFFICIENCY—Mercedes-Benz’s take on fuel economy and emission reduction technologies. It also brought turbocharging into mainstream C-Class models.

Top Engine Variants:

• C180 CGI (1.6L Turbo I4):
  Smaller, turbocharged engines for better fuel economy (~156 hp).

• C250 CGI (1.8L Turbo I4):
  Balanced performance with ~201 hp.

• C300/C350 (3.0L – 3.5L V6):
  Powerful and smooth V6 options (228–302 hp).

• C63 AMG (6.2L V8):
  Naturally aspirated V8 with 451 hp—brutal and iconic.

Key Tech Additions:

• Introduction of turbocharging over supercharging.

• Start/Stop functionality in BlueEFFICIENCY variants.

• Improved automatic transmissions (7G-Tronic).

• First C-Class with fully digital driving aids.

Verdict: W204 engines offered a great balance between raw power and modern efficiency. The C63 AMG became a legend thanks to its M156 V8 engine, known for its roar and performance.

4. Fourth Generation (W205: 2014–2021)

The Turbocharged Era

W205 marked a major shift towards lightweight construction (using aluminum) and full turbocharged lineups. It also introduced plug-in hybrids and advanced infotainment systems.

Major Engine Options:

• C200 (2.0L Turbo I4):
  Turbocharged with improved torque and fuel economy (~181–204 hp).

• C300 (2.0L Turbo I4):
  Same displacement but tuned for ~241 hp.

• C350e (Plug-in Hybrid):
  Combined electric motor and turbocharged 2.0L (~275 hp total).

• C43 AMG (3.0L Bi-Turbo V6):
  Fast and nimble with 362 hp.

• C63 AMG (4.0L Bi-Turbo V8):
  A twin-turbo beast with 469–503 hp in the S variant.

Technological Innovations:

• Extensive use of twin-turbocharging.

• Enhanced 9G-Tronic automatic gearbox.

• First plug-in hybrid C-Class.

• Driving modes, adaptive dampers, and full driver assistance systems.

Verdict: The W205 brought refinement and performance in equal measure. The AMG models were quicker and more efficient than ever, and even entry-level models felt premium.

5. Fifth Generation (W206: 2021–Present)

Downsizing with Hybrid Support

The W206 C-Class has fully embraced electrification. All internal combustion engines now come with some form of mild hybrid assistance (48V system), emphasizing sustainability.
