🔍 Model Background

The Mercedes-Benz C230 W203 2.5L V6 (2005–2007) was a sporty and refined variant of the second-generation C-Class, offering European performance, luxury, and daily usability in a compact package. This model stood out for introducing a new-generation V6 engine that delivered enhanced power and smoothness over earlier four-cylinder options.

At its heart was a 2.5-liter DOHC V6 engine producing around 201 horsepower and 181 lb-ft of torque. This engine, part of Mercedes’ M272 family, was paired with either a 6-speed manual transmission or a 7-speed automatic, giving the C230 a more engaging and responsive character than many of its rivals in the entry-luxury segment.

Visually, the C230 featured a sportier appearance, often with AMG-style trim, alloy wheels, and a lowered stance. Inside, it offered high-quality materials, supportive seats, and advanced features like dual-zone climate control, a premium sound system, and optional navigation—all wrapped in a driver-focused layout.

Produced from 2005 to 2007, the C230 W203 2.5L V6 served as a dynamic bridge between economy and performance in the C-Class range. It’s remembered today for its smooth V6 power delivery, solid build quality, and understated sportiness, making it a standout among compact premium sedans of its era.
