The Mercedes-Benz E-Class underwent a significant transformation with the introduction of the W210 chassis in 1996, marked by its distinctive rounded headlights. While the initial year featured only the inline-six E320, 1997 marked the arrival of a V8 variant that truly captured enthusiasts’ attention: the 1997 E420 Mercedes.
This model year brought back the V8 power to the E-Class lineup in the form of the E420. Nestled under the hood was the formidable M119 engine. This 4.2-liter V8 was a sophisticated piece of engineering, boasting quad camshafts and 32 valves, delivering approximately 275 horsepower. Paired with the then-new 722.6 five-speed automatic transmission, the 1997 E420 Mercedes offered a genuinely spirited driving experience. This combination provided a level of performance that was both refined and exhilarating, solidifying its place as a desirable model in the E-Class history.
For the subsequent model year, 1998, Mercedes-Benz replaced the E420 with the E430. While fundamentally similar cars, the key difference lay in the engine. The M119 V8 was superseded by the next-generation M113 V8 engine in the E430. The M113, while slightly less complex with two camshafts and 24 valves, maintained similar power output. Importantly, it brought improvements in fuel economy and significantly reduced emissions, reflecting evolving automotive technology and environmental considerations.
Choosing between a 1997 E420 Mercedes and the later E430 often comes down to nuances rather than drastic differences. For the average driver, the performance distinction would be negligible in everyday driving scenarios. Both engines are considered robust and reliable, with their own specific maintenance considerations. The M119 in the 1997 E420 Mercedes is known for potentially needing oil tube replacements over time, a manageable maintenance task. The M113 in the E430 is associated with harmonic balancer issues, but this is also a relatively straightforward and cost-effective repair if addressed proactively. On the whole, the M113 engine generally benefits from longer service intervals and less frequent spark plug changes, potentially translating to slightly lower long-term maintenance costs compared to the M119.
In conclusion, the 1997 E420 Mercedes stands as a compelling choice for those seeking a V8-powered W210 E-Class. It delivers a blend of classic Mercedes-Benz luxury, robust performance from its M119 engine, and a distinctive place in the model’s evolution. While the E430 offers advancements with the M113 engine, the 1997 E420 Mercedes remains a highly desirable and capable vehicle, especially for enthusiasts who appreciate the engineering and character of its quad-cam V8.
