Just looked at our homepage, they always say "Daimler ..." (no 's). An explanation could be that the Brand name and not the manufacturer is meant.

Hallo Bama Torsten,

aber es handelt sich doch um die Produkte von Daimler (manufacturer)?

Nee, der Hersteller ist Mercedes-Benz.
Bin mit meiner Erklärung aber auch nicht so richtig glücklich...

Geht nicht beides? Es gibt meines Erachtens dabei nur einen kleinen Bedeutungsunterschied.

Daimler's products = die Produkte von Daimler (Daimlers Produkte)
Daimler products = die Produkte der Marke Daimler (Daimler-Produkte)

#3:

Der *Hersteller* heißt Daimler (bis vor kurzem Daimler-Chrysler).

Mercedes-Benz ist die *Marke* von Daimler für Kraftfahrzeuge.

Either one works for me.

The two phrases do have slightly different feel, a little hard to explain. Daimler's products would mean products of Daimler (in other words possessive). Daimler products would mean products produced from Daimler, or products produced by Daimler. Daimler's products puts the emphasis on Daimler; Daimler products puts the emphasis on the products.

But the meaning is really very close, and there's no reason to prefer one phrase rather than the other.

On balance, I think Daimler products is slightly preferable.

Slight correction: Daimler products would mean products from Daimler, or products produced by Daimler. [my "produced from" is incorrect]
