Powertrain & Engine Architecture
The E 240 was powered by the M112 E 24 engine, a 2.4-liter naturally aspirated V6. This engine, part of Mercedes-Benz’s new modular engine family, featured all-aluminum construction, a significant departure from the cast-iron blocks of previous generations. The M112 utilized a SOHC (Single Overhead Camshaft) valvetrain with three valves per cylinder (two intake, one exhaust), optimizing gas flow and contributing to improved efficiency. Fuel delivery was handled by a multi-port fuel injection system, ensuring precise fuel metering. The engine produced 170 horsepower at 5900 rpm and 225 Nm (165.95 lb-ft) of torque at 3000 rpm. The five-speed manual transmission was standard, providing a direct connection between the engine and the rear wheels. While an automatic transmission was available, the manual offered a more engaging driving experience and slightly improved fuel economy.
Driving Characteristics
The E 240, with its 170 hp and manual transmission, offered a balanced driving experience. Acceleration from 0 to 60 mph took approximately 9.1 seconds, and it reached a top speed of 223 km/h (138.57 mph). Compared to the more powerful E 320, the E 240 felt less urgent in acceleration, but it provided ample power for everyday driving and highway cruising. The manual gearbox, while not particularly sporty, was precise and easy to use. The suspension, tuned for comfort, absorbed bumps effectively, providing a smooth ride. The E 240’s handling was predictable and stable, making it a confidence-inspiring car to drive. Compared to the automatic version, the manual offered more control and a more connected feel, particularly on winding roads.
Equipment & Trim Levels
The E 240 came standard with a respectable array of features, including power windows, power locks, air conditioning, and an AM/FM stereo. Upholstery was typically cloth, although leather was available as an option. Optional extras included a sunroof, heated seats, automatic climate control, and a premium sound system. The interior design was typical of Mercedes-Benz at the time – understated elegance with high-quality materials. The dashboard layout was functional and easy to use, with clearly labeled controls. Trim levels were relatively simple, with most options being added individually rather than packaged into specific tiers.
Chassis & Braking
The W210 E-Class featured a robust chassis with double wishbone suspension at the front and an independent multi-link suspension at the rear. This setup provided a comfortable ride and good handling characteristics. The E 240 was equipped with ventilated disc brakes at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, enhancing safety and control during hard braking. The steering was a rack-and-pinion system with hydraulic power assistance, providing precise and responsive steering feel. The standard tire size was 205/65 R15, mounted on 7J x 15 inch wheels.
Market Reception & Comparison
The E 240 was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and fuel efficiency. However, some critics noted that its performance was not as exciting as that of its more powerful siblings. Compared to the E 220, the E 240 offered a noticeable performance boost, while remaining relatively affordable. Compared to the E 320, it was less powerful but more fuel-efficient and less expensive to maintain. Fuel economy was a strong point for the E 240, achieving around 22.8 US mpg in combined driving. Reliability was generally good, although some owners reported issues with the electronic systems.
Legacy
The W210 E-Class, including the E 240 variant, established a reputation for durability and longevity. The M112 engine proved to be a reliable powerplant, capable of high mileage with proper maintenance. Today, the E 240 remains a popular choice among enthusiasts and collectors, particularly those seeking a classic Mercedes-Benz that is both comfortable and reliable. While parts availability can be a concern for older models, the E 240’s robust construction and relatively simple design make it a relatively easy car to maintain. The E 240 represents a sweet spot in the W210 lineup, offering a good balance of performance, luxury, and affordability.
