For those navigating the pre-owned Mercedes-Benz market, understanding model designations and generational shifts is crucial. Let’s clarify the story surrounding the Mercedes Benz E420, particularly within the context of the E-Class evolution. The E420 nameplate appears in two distinct Mercedes-Benz chassis, the W124 and the subsequent W210.
The Transition: From W124 to W210 E-Class
The predecessor to the W210 E-Class, the W124 chassis, housed the 400E and E420 models from 1992 to 1995. This generation represents what many consider the “old-old” E-Class. However, significant changes arrived with the 1996 model year and the introduction of the W210 chassis. This new iteration of the E-Class was instantly recognizable by its distinctive rounded headlights, a departure from the more angular design of its predecessor. Interestingly, the initial W210 lineup for 1996 didn’t feature a V8 engine option. Instead, the flagship model was the E320, powered by an inline six-cylinder engine.
The Arrival of the E420 in the W210 Chassis (1997)
The V8 engine made its return to the W210 E-Class in 1997 with the introduction of the Mercedes Benz E420. This model marked a significant step forward in performance, equipped with the potent M119 V8 engine. This advanced engine boasted a quad-cam, 32-valve configuration and produced approximately 275 horsepower. Paired with the then-new 722.6 five-speed automatic transmission, the E420 delivered a genuinely spirited driving experience.
E420 vs. E430: A Successor’s Tale (1998)
The Mercedes Benz E420’s reign was relatively short-lived. In 1998, it was superseded by the E430. While fundamentally the same vehicle, the E430 featured a new generation V8 engine, the M113. This engine, while less complex with two camshafts and 24 valves, maintained similar power output to the M119. Furthermore, the M113 offered improved fuel economy and significantly reduced emissions.
M119 Engine Considerations
While both engines are robust, the M119 in the E420 is known for a potential issue with oil tubes. However, failure of these tubes, while requiring attention, typically doesn’t lead to catastrophic engine damage.
M113 Engine Considerations
The M113 in the E430 has its own known weak point: the harmonic balancer. Fortunately, this is a relatively straightforward and inexpensive repair, especially if addressed before complete failure. Beyond this, the M113 generally offers longer service intervals and less frequent spark plug changes, potentially resulting in slightly lower long-term maintenance costs.
Conclusion: E420 or E430 – Which V8 E-Class to Choose?
Ultimately, both the Mercedes Benz E420 and E430 represent excellent choices for a V8-powered W210 E-Class. For the average driver, the performance difference between the two is negligible. Neither engine has inherent widespread problems that would make one definitively preferable to the other. While the M113 in the E430 might offer a slight edge in terms of long-term maintenance costs, both models provide a compelling blend of luxury and V8 performance within the W210 E-Class family.
