I always wonder why almost all modern V8/V6 engines start to use 2 upstream O2 sensors, 1 per cylinder bank, plus at least 1 downstream O2 sensor, that's more than MB M119's single O2 sensor.

My 11 year old 400E just passed emission test last week, the maximum pollution I got for idle and 40kmph was HC of 40 ppm and CO of 0.03%, does anybody know what numbers one normally gets from new V8 MBs?
99 BMW 540i 6-speed 110K Km
03 SAAB 9-5 wagon 80K Km
92 400E (Sold) 245K km
Still missing the days with the Benz, it kept me busy.
