Actually, temperature, humidity, and other weather conditions affect the DA (density altitude), which affect the runs greatly. At Fontana, we ran the same cars, same drivers, same time of day, same track of course, but two different DA: one was 1450 ft while the other was 3200 ft. The E/CLS63 dropped from 13.2 seconds to 12.3 seconds in the lower DA environment. That is almost a 1 second difference in ET because of DA. At Palmdale, even though the track is at higher elevation, DA was even much higher, and these cars were averaging 14.2 seconds while C6 Z06s were averaging 13.7 seconds . Weather conditions affect the DA, which can affect the times immensely. We have experimented with this so much, and I think most of the timeslips are still posted in the E55 section of the forum.

Please note, I'm not saying one car is definately faster than the other, I'm simply saying their performance is very close to each other, and the race will likely be determined by the driver. I actually think the C55 has a slight edge due to the better top-end pull.

Wawy, sorry for the side-track, congrats on the car; Diamond Black is one of my favorite colors........

Pictures please.........

One wonders how they could charge so much when Sponsors like LET sells them for the C32 for like 1k....(and people still complain they are too much) cause they compare them to American V6 and V8. Its MB AMG and vendors know they can charge more thinking we are still willing to pay...

You are absolutely correct about "DA". I should've stated that more clearly in my response. I was simply assuming they were testing at the same track, just possibly at different times of the year therefore different weather elements.
Believe me, I understand about loss of horsepower at altitude. When I drove my Z28 from Houston to Aspen, CO one year, it went from feeling fast and fun to feeling like it was choking for air and dragging an anchor. The average hp loss equates to 3% per 1000 ft, therefore when I reached the 8000 ft altitude of Aspen I was down about 24% hp. It's an art to get a car to run well at altitude per all the air/fuel ratio adjustments necessary to compensate.
Anyway, thanks for adding the additional technical clarification. You are correct sir!

Here's a quick pic for now. It's in our underground parking so it's not the greatest. I've parked it for the winter and will take better ones when I bring it out in the Spring/Summer...
