I have about 700 mi so far. Anytime I barely drive the car hard ( stepping on gas from stop/stop light, RPM maybe to 4K+) l notice the burnt new engine smell.

On my other 2015 vehicle (MB C300) I remember the new engine smell was gone pretty quick.

Im just wondering how many miles to reach before no more burnt smell or otherwise to be concern about.

thanks

you are not suppose to accelerate harshly during the break in period (first 1000 miles)
After 1000 miles if the engine still has a smell you should get that checked. I did not notice a smell on mine.
