Ok so I couldn't help it today and, without flooring it, let the engine rev close to 6k rpm's but I only did about 90 mph (I think) before backing off. My wagon has close to 900 miles on it. This thing just wants to go so I let it up to that point. Shouldn't hurt it right?

 

I think you just threw a rod, take it back to the dealer immediately for a complete engine overhaul!!

 

 

You'll probably be ok, a lot of people beat the snot out of these cars from day 1. What I worry about most with break in is the rear end gears wearing in right, there is a lot of torque going to those gears, hence the 2 K gear oil change recommendation, they are fairly finely machined to handle the kind of torque they see. If they don't wear in properly you'll be stuck with a whining noise at certain speeds the rest of the cars life or until the gears are replaced. Other than that I don't worry about the engines much, they can take a beating from day one.

 

Lol I think I've done what you did within the first 1 mile with every new car I've owned.

 

 

Beat on it from day 1.

 

Ok Mr. Smarty pants, I'll have you know that I anticipated this so I drove in reverse for about a mile to roll back any potential damage. I are smart!

 

My good Sir, I just read the patriot act and in section 500 page 35,000 paragraph 2,000,000.05 it specifically stipulates that "all things being considered let it be known that it is commendable and, indeed, recommended to drive in an exuberant manner the E63s for short periods of time while still in the break in period. Just don't tell Mercedes Benz." And since my wagon is one of only three Edition 1's in the U.S. I'd imagine Car Max would offer me at least $1500 for the now steaming pile. What have I done!!!!!!!!!

 

I believe that VIC55 did about the same shortly after getting his Edition 1 sedan. Ok so I'm no longer worried and the good news is that so far, no issues or ck engine light.

 

Well I did this from about 45mph so it probably put a lot less stress on the drive train that hitting it hard from a dead stop. Thanks for the diff info. I believe others have stated the same and, so far, no reared whine or other unusual noises. Car is pretty tight and squeak free.

 

Yea, when I first test drove a white wagon with some 300 miles on it. the SA stomped on the gas and then slammed on the (carbon/ceramic) brakes. Was mighty impressive but I wondered how many times he's done this in this particular car. Like you, I wouldn't buy this one.

 

So I take it that you've had no issues so far with your E63s? If not then maybe this is a better way than babying it too much during the first 1k miles?

 

I never break in any of my cars. When I left the dealership lot, I floored it all the way on sport+. No problems until this day. So don't even worry lol

 

Wait, there are Edition 1 Wagons??????? Good sir, I take everything back and now am impressed. I actually had no clue they did that in the wagon, just the sedan. Nice!!!!
