⚙️ Engine Specifications

Available Engine Options:

Multiple engine options were available for the W204 CLC-Class, typically including 1.8L, 2.0L, and 3.5L gasoline engines, and various diesel variants (e.g., 2.1L CDI). Specific engine codes and variants would be detailed in the manual (e.g., M271, OM651).

Horsepower And Torque:

Varies significantly by engine. For example, a 1.8L turbocharged gasoline engine might produce around 184 hp and 270 Nm torque, while a 3.5L V6 could offer upwards of 292 hp and 365 Nm. The manual will provide precise figures for each variant.

Fuel Delivery Type:

Typically direct injection (CGI for gasoline) or common rail direct injection (CDI for diesel).

Fuel Type Recommendation:

Premium unleaded gasoline (e.g., RON 95/98) for gasoline engines; Euro 5 compliant diesel for diesel engines. Specific grades and octanes detailed in the manual.
