The Mercedes-Benz E 320 4MATIC, produced from July 1999 to March 2002, represents a significant iteration of the W210 E-Class facelift. Positioned as a mid-to-upper trim level, this variant combined a potent 3.2-liter V6 engine with Mercedes-Benz’s 4MATIC all-wheel-drive system and a five-speed automatic transmission. It aimed to deliver a blend of performance, luxury, and all-weather capability within the E-Class range, appealing to buyers seeking a refined driving experience without sacrificing practicality. The W210 facelift, introduced in 1999, addressed many criticisms of the earlier W210 models, improving build quality and aesthetics.

Powertrain & Engine Architecture
The heart of the E 320 4MATIC is the M112 E 32 engine, a 3.2-liter naturally aspirated V6. This engine, part of Mercedes-Benz’s modular V-engine family, featured a 60-degree V-angle and a single overhead camshaft (SOHC) design per cylinder bank. The M112 utilized a three-valve per cylinder configuration (two intake, one exhaust) and multi-port fuel injection. This engine was known for its smooth power delivery and relatively high specific output for a naturally aspirated engine of its time. The engine code 112.941 specifically denotes the version equipped for the W210 chassis. Paired with the engine was a five-speed automatic transmission (typically the 722.6), chosen for its smooth shifting and suitability for luxury applications. This transmission was electronically controlled, adapting shift points based on driving conditions and throttle input.
Driving Characteristics
The E 320 4MATIC offered a comfortable and capable driving experience. The 224 horsepower and 315 Nm (232 lb-ft) of torque provided adequate acceleration, with a 0-60 mph time of around 7.9 seconds. While not a sports car, the engine delivered strong mid-range power, making it well-suited for highway cruising and overtaking. The 4MATIC all-wheel-drive system enhanced traction, particularly in inclement weather, providing a surefooted feel. The automatic transmission, while smooth, wasn’t particularly quick to downshift, and lacked the responsiveness of a manual gearbox. Compared to the E 430 with its larger V8, the E 320 offered a more fuel-efficient option, but with a noticeable reduction in outright performance. Compared to the diesel variants like the E 320 CDI, the gasoline E 320 provided a more refined and quieter driving experience, albeit with higher fuel consumption.
Equipment & Trim Levels
The E 320 4MATIC typically came well-equipped, reflecting its position in the E-Class lineup. Standard features included leather upholstery, power-adjustable front seats with memory function, automatic climate control, a premium sound system, and wood trim. Optional extras included a sunroof, navigation system, heated seats, and upgraded wheels. The interior design was typical of Mercedes-Benz at the time, emphasizing luxury and comfort. Dashboard layout was relatively straightforward, with clearly marked controls. The 4MATIC models often included unique badging and exterior trim details to distinguish them from rear-wheel-drive versions.
Chassis & Braking
The W210 E-Class featured an independent suspension system all around. The front suspension utilized wishbones, while the rear employed a multi-link setup with a stabilizer bar. This configuration provided a comfortable ride and good handling characteristics. The E 320 4MATIC was equipped with ventilated disc brakes at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard. The 4MATIC system added weight compared to the rear-wheel-drive models, which slightly impacted handling agility, but significantly improved stability and traction.
Market Reception & Comparison
The E 320 4MATIC was generally well-received by automotive critics. It was praised for its comfortable ride, refined engine, and all-weather capability. However, some reviewers noted that the automatic transmission could feel sluggish at times. Fuel economy was considered average for a vehicle in its class. Compared to the BMW 5 Series and Audi A6 of the same era, the E 320 4MATIC offered a more luxurious and comfortable experience, but perhaps lacked the same level of sporting engagement. The 4MATIC system was a key selling point for buyers in regions with harsh winters or challenging road conditions.
Legacy
The M112 engine family, including the 3.2-liter variant found in the E 320 4MATIC, proved to be relatively reliable. With proper maintenance, these engines can accumulate high mileage. Common issues include occasional oil leaks and sensor failures. The 722.6 automatic transmission is also generally durable, but may require fluid changes and occasional servicing. Today, the W210 E 320 4MATIC represents an affordable entry point into the world of Mercedes-Benz ownership. Well-maintained examples are sought after by enthusiasts who appreciate their classic styling, comfortable ride, and robust engineering. The 4MATIC system continues to be a desirable feature, particularly in areas with inclement weather. However, potential buyers should be aware of the age-related maintenance requirements associated with any vehicle of this era.
