Powertrain & Engine Architecture
The heart of the 320 CE is the M104.992 3.2-liter inline-six engine. This engine, a cornerstone of Mercedes-Benz’s engineering prowess, featured a cast iron block and aluminum cylinder head. It employed multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain, contributing to its smooth power delivery and relatively high specific output. The engine’s design prioritized refinement and durability over outright peak horsepower, a hallmark of Mercedes-Benz engines of the period. The automatic transmission used was a four-speed unit, designed to provide smooth and comfortable shifts. While not as sporty as a manual transmission, it complemented the car’s grand touring character. The transmission was electronically controlled, offering adaptive shifting based on driving conditions.
Driving Characteristics
The 320 CE Automatic offered a distinctly different driving experience compared to its 280 CE or 220 CE siblings. The increased displacement and power of the 3.2-liter engine provided noticeably stronger acceleration, with a 0-60 mph time of around 7.4 seconds. While not a sports car, the 320 CE felt confident and capable on the open road. The automatic transmission, while smooth, did result in some power loss compared to the available manual gearbox. Gear ratios were tuned for comfortable cruising, with a focus on mid-range torque rather than high-revving performance. The rear-wheel drive configuration provided a balanced feel, although traction could be a concern in adverse weather conditions.
Equipment & Trim Levels
The 320 CE came standard with a generous array of features, reflecting its position as a premium model. This included leather upholstery, power windows, power locks, and a sunroof. Air conditioning was also standard. Optional extras included a premium sound system, heated seats, and automatic climate control. The interior trim was typically finished in wood veneer, adding to the car’s luxurious ambiance. The dashboard layout was typical of Mercedes-Benz at the time, with a clear and functional design. The exterior featured color-coded bumpers and side skirts, and alloy wheels were standard.
Chassis & Braking
The C124 chassis was renowned for its robust construction and excellent ride quality. The 320 CE featured a wishbone front suspension and an independent multi-link rear suspension, providing a comfortable and controlled ride. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, enhancing safety and stability. The steering was a recirculating ball system with hydraulic power assistance, offering a good balance of feel and ease of use. Stabilizer bars were fitted front and rear to reduce body roll during cornering.
Market Reception & Comparison
The 320 CE was generally well-received by automotive critics. It was praised for its smooth engine, comfortable ride, and luxurious interior. However, some critics noted that the automatic transmission dulled the driving experience somewhat. Compared to the 280 CE, the 320 CE offered a significant performance upgrade, but at a higher price point. The 320 CE was also more expensive to maintain than the lower-displacement models, due to the more complex engine and higher-quality components. Fuel economy, while reasonable for a car of its size and performance, was not a strong point, averaging around 16 mpg in the city and 29 mpg on the highway.
Legacy
The M104 engine, found in the 320 CE, is known for its durability and reliability. With proper maintenance, these engines can easily exceed 200,000 miles. The C124 chassis is also highly regarded for its build quality and longevity. Today, the 320 CE is a sought-after classic car, appreciated by enthusiasts for its blend of performance, luxury, and engineering excellence. While finding well-maintained examples can be challenging, the 320 CE remains a rewarding ownership experience for those who appreciate a classic Mercedes-Benz coupe. Parts availability is generally good, although some specific components may be difficult to source. The car’s enduring appeal lies in its ability to provide a comfortable and refined driving experience, while still offering a respectable level of performance.
