The Mercedes-Benz E55 AMG has earned a reputation for being a fast car, thanks to a supercharged 5.4-liter V8 engine that could deliver 469 hp at 6,100 rpm with up to 531 pound-feet of torque at 4,000 rpm. While this executive car can boast about being very desirable, it isn't a perfect vehicle. Here are some issues that its drivers have encountered over the years with Mercedes-Benz E55 AMG parts and accessories:
The AirMatic suspension system is an E-class feature that is supposed to adapt to various driving styles while at the same time reducing the E55's body roll. However, it can also cause a sense of unfamiliarity for the driver because it doesn't allow him to experience feedback from his car.
Newer E55 models are 472 pounds heavier than the previous versions that weighed in at 3,765 pounds. While it may not seem bulky when it's just moving on a straight path, the extra weight can be a problem when doing quick turns and brakes. The newer model needed 173 feet to decelerate from 70 miles per hour to a complete stop.
The program that handles the brakes also feels too intrusive since it constantly applies its own interpretation of what the brakes should be doing. It causes the car to lurch and lunge at every stop instead of braking smoothly.
High speed and near-limitless power should be controllable with surgical precision and accuracy. However, the E55 has also been criticized for its steering. It doesn't turn curves quite as sharply or as consistently as its competitors do. There's also the unfortunate fact that its steering wheel doesn't quite feel right as it seems too big without being as substantial, especially with its steering-assist program. This makes the wheel wobble slightly when returning to the center.
Because of this, the car isn't quite as finessed as it should be. Just a little push on the accelerator will launch the car forward much too quickly. Still, as the E55 builds up speed, the initial feeling of fear can turn into delight. The street-safe Mercedes-Benz E55 AMG feels like a racecar thanks to the combination of engine and exhaust sounds and the added adrenaline rush to the driver's bloodstream.
