- The S600 (1992-1995) had a 6000 cc V12 engine producing 420 HP and featured an all-wheel-drive system.
- The 600SE, 600SEL, and 600SEC (1993-1998) also used the V12 engine but with 412 HP, and the 600SEL added a rear-biased all-wheel-drive system.

- The use of advanced materials such as fiber-reinforced plastic for the roof
- Improved aerodynamics with features like active air control and an adjustable front splitter

The interior also featured advanced technology for its time, including:
- A driver information center displaying navigation data, vehicle settings, and other relevant information
- Electronic climate control with sensors monitoring both inside and outside temperatures
- An advanced audio system capable of playing CDs or cassettes
Safety features included:
