Torque Output Range:

Varies significantly with engine size and type.

Valvetrain:

Overhead camshaft (OHC), 2 valves per cylinder (some performance variants had 4 valves per cylinder).

🔧 Transmission

Transmission Type:

Typically a 4-speed or 5-speed manual transmission was standard on many models.

Transmission Type:

Optional 4-speed automatic transmission (722.4) and later a 5-speed automatic transmission (722.5).

Fluid Type Automatic:

Typically Mercedes-Benz Specification 236.1 or 236.3 automatic transmission fluid (ATF).

Fluid Type Manual:

Gear oil, typically SAE 75W-80 or SAE 75W-90 GL-4/GL-5 specifications depending on application.

📐 Dimensions

Length:

Approximately 4420 mm (174.0 in) for early models, increasing slightly in later versions.
