Based on these specs the E55 400lbs lighter than the CLS55 with same HP but it shows that E55 is slower.
Can someone make sense of what I read at the Car and Driver review? Also it show E55 limited although I've driven the car 160MPH +

traction issues with the E55 explains this small discrepancy i guess you are seeing in 0-60 and 0-100.

if your car goes above 160, then it is possible you have a tune on your car already that has deleted the factory speed limiter/governor.

How can I tell if I have a tuned car? I bought the car from MB with CPO. Should this disqualify this car from MB's CPO program at the time of purchase?

the CLS55 are actual test results where as the E55 are estimates.
