Is this how a 0 to 60 test is performed? A stock 550 should be between 5 to 5.2 seconds, which I never can achieve and plus mine is tuned. I think it's my fault. All I do is hit the gas at a stop light and check my results on a phone. I don't hold down the brake and rev the engine nor did I put the car in S mode or change the suspension.

So this brings me to the question..how is a proper 0 to 60 test done? I can't go on a track here but I want to try it on an open back road.

My car is stock and does 0-62mph (0-100km/h) in 4.6 to 4.9, depending on road condition. Measured with RACELOGIC Performance Box (10Hz GPS).

Are you serious? That's way below Mercedes's numbers and also test drives by pro drivers. Not sure how you are getting such low numbers. How do you perform a 0 to 60 test? Also, are you getting these times with paddles or auto?

Mercedes Germany was claiming 0-62mph in 4.8 for 4matic cars with 2 person on bord. So my car is pretty much spot on.

However, I do have the Twin Turbo engine (2012-2016). Two buddies of mine have 2010-2011 5.5 N/A E550ies! One 4matic, one rwd. I was able to measure the 4matic with two person on bord and it went 5.3 for 0-62. That really surprised me, as the car feels a lot slower than the twin turbo. If one looks carefully on the data, 1st gear acceleration is similar between both engines. 2nd gear is stronger in the twin turbo. 3rd gear is even stronger. Therefore 62-125mph (100-200km/h) is a huge difference (11s vs. 14s!)
