For better traction and acceleration, the Panamera has larger standard rear tires than the S-Class (275/45R18 vs. 255/45R18). The Panamera’s optional rear tires are larger than the largest rear tires available on the S-Class (295/35R20 vs. 275/40R19).
For better handling and stability, the average track (width between the wheels) on the Panamera is 2.3 inches wider in the front and 1.9 inches wider in the rear than the track on the S-Class.
The Panamera Turbo 4 handles at .97 G’s, while the S600 pulls only .80 G’s of cornering force in a Car and Driver skidpad test.
The Panamera Turbo 4 goes through Road & Track’s slalom 9 MPH faster than the S550 (69.1 vs. 60.1 MPH).
The Panamera S executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the S550 (25.7 seconds @ .72 average G’s vs. 27.2 seconds @ .64 average G’s).
For better maneuverability, the Panamera’s turning circle is .7 feet tighter than the S-Class’ (39.3 feet vs. 40 feet).
The Porsche Panamera may be more efficient, handle and accelerate better because it weighs about 600 to 700 pounds less than the Mercedes S-Class.

The Panamera’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The S-Class does not have an oil pressure gauge.
To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The S-Class doesn’t offer a rear wiper.
To help keep rear passengers entertained, the Panamera offers optional rear seat controls for the radio which can play a separate audio source. The S-Class doesn’t offer rear seat audio controls.
