Any idea of E450 4Matic 0 to 60 time
 

I have a 2019 E450 4Matic sedan on order. I have a 2018 E400 but there was some misrepresentation of one of the cars features so the dealer has made it very easy for me to change to a 2019 car which will have the feature that was missing on the 2018 car.(Live traffic in Canada)

The 450's HP is about 10% more than the 400's but the torque increase is more modest at around 5%. The Canadian website shows the 0 to 100Km (approximately 62 mph) time for the 2018's at 5.2 seconds which probably translates to about 5.1 for the 0 to 60. Does anyone know what the 2019 times are or are likely to be?

Not sure why I am interested in this as the 2018 is plenty zippy enough for me (particularly in sport mode) but I am :-)

Mercedes lists it at 5.0 seconds

 MSRP $59,950  3.0L V6 biturbo engine  Horsepower 362 hp  Torque 369 lb-ft  5.0 sec est. (0-60 mph)  Launch date: Q3 2018

I read somewhere recently that a test of the E450 was 4.9 seconds 0 - 60. That's really splitting hairs. Even the difference between 5.2 and 5.0 is incredibly small.
