Rumors about a partnership between Aston Martin and Maybach first appeared at the end of last year when we reported that the two companies would team up for a luxury sedan. Now, AutoCar reports that the two companies are set to bring a concept car developed together to the Frankfurt show in September 2011.

While neither Aston Martin->ke13 nor Maybach->ke52 would comment on this rumor, it is believed that the concept to be displayed in Frankfurt will be a luxury car with a high-quality interior finished to the hand-crafted standards of a British luxury saloon.

This news shouldn't really surprise anyone considering Mercedes needs to decide by the end of June which partner they will choose to develop replacements for the 57 and 62 saloons. This type of partnership is mutually beneficial because Aston Martin can bring its interior design skills to the table, particularly the use of traditional materials in conjunction with hi-tech features, and Mercedes can share its new alloy body technology and engines for third-generation Vantage and DB9 models.
