It seems that Mercedes and Nissan have some agreements going, rumors. I would love to have an Infiniti with a Mercedes built motor!Infiniti has openly admitted they are aiming squarely at audi. They want to recreate and surpass what audi has done in the past 20 years. Not sure if anyone remembers old audi but they were not really a luxury maker. They did some racing stuff and in the 80's were part of a huge unintended acceleration scandal.
Infiniti even went as far as to hire Johan De Nysschen, former president of U.S. operations.
BTW the q30 will be sharing parts with the Mercedes A-class.
