If it's a Daimler-Benz public information officer who pens the article,then they at least allow that the A2 numbers are credible.Which is very useful information.

The comparison is not entirely fair.

The Mercedes allegedly has a device that sucks in air at the front and blows it out in the wake at the back, heated and mixed with CO2.
Though it helps aerodynamically, it makes the Mercedes use a lot more gas that the Tesla.
In two weeks time further details will become clear

It does not sound like it helps enough aerodynamically.

I found a picture of their first, rather crude, usage of this device in an automobile:


Apparently the aerodynamics needed all the help it could get.

Same type, driven by a contemporary:
