Powertrain & Engine Architecture
The heart of the 320 CE is the M104.992 3.2-liter inline-six engine. This engine, a significant upgrade from the earlier M103, featured a more modern design with four valves per cylinder and a double overhead camshaft (DOHC) configuration. The M104 was known for its smoothness and responsiveness. Fuel delivery was handled by a Bosch multi-port fuel injection system, optimizing combustion efficiency and power output. The engine produced 220 horsepower at 5500 rpm and 310 Nm (228.64 lb-ft) of torque at 3750 rpm. The 5-speed manual transmission was standard, providing precise gear changes and enhancing the driving experience. While an automatic transmission was available, the manual was favored by enthusiasts for its improved performance and engagement.
Driving Characteristics
The 320 CE with the manual transmission offered a compelling driving experience. Acceleration to 60 mph was achieved in approximately 7.6 seconds, and it could reach a top speed of 235 km/h (146 mph). The inline-six engine delivered a linear power curve, providing strong acceleration throughout the rev range. The well-tuned suspension, featuring wishbones at the front and an independent multi-link setup at the rear, provided a comfortable ride while maintaining excellent handling characteristics. Compared to the lower-powered 220 CE or 280 CE models, the 320 CE offered a noticeable performance advantage, making it a more engaging and rewarding vehicle to drive. The manual gearbox allowed for greater control and driver involvement, while the automatic, though smoother, slightly diminished the sporty feel.
Equipment & Trim Levels
The 320 CE came standard with a generous array of features, reflecting its position as a premium coupe. Interior appointments included leather upholstery, wood trim, and power-adjustable front seats. Standard equipment also included an anti-lock braking system (ABS), power windows, central locking, and a high-quality sound system. Optional extras included a sunroof, automatic climate control, and upgraded audio systems. The interior design was characterized by its understated elegance and high-quality materials, creating a luxurious and comfortable cabin environment.
Chassis & Braking
The C124 chassis was renowned for its rigidity and safety. The 320 CE benefited from a robust suspension system designed to handle the increased power output. The front suspension utilized wishbones, while the rear featured an independent multi-link setup, providing a comfortable ride and precise handling. Braking duties were handled by ventilated discs at the front and solid discs at the rear, providing ample stopping power. The ABS system further enhanced safety by preventing wheel lockup during hard braking.
Market Reception & Comparison
The 320 CE was well-received by automotive critics, who praised its performance, handling, and luxurious interior. It was often compared favorably to its rivals, such as the BMW 3 Series Coupe and the Audi Coupe. While the 320 CE offered a higher level of refinement and comfort than some of its competitors, it was also more expensive. Fuel economy, at 14.7 l/100 km (16 US mpg) in urban conditions, was typical for a high-performance coupe of its era. Compared to the 220 CE and 280 CE, the 320 CE offered significantly more power and performance, but at a higher price point and with slightly increased running costs.
Legacy
The Mercedes-Benz C124 320 CE remains a sought-after classic car today. The M104 engine is known for its durability and reliability, provided it is properly maintained. Well-maintained examples command a premium in the used car market. The C124’s robust construction and timeless design have ensured its enduring appeal. While parts availability can be a concern for older vehicles, a dedicated community of enthusiasts and a network of specialist suppliers help to keep these cars on the road. The 320 CE represents a high point in Mercedes-Benz coupe design and engineering, offering a blend of performance, luxury, and build quality that continues to impress decades after its production ended.
