According to a report from Auto Motor und Sport, Toyota is considering a partnership with Daimler to build Mercedes-Benz' A- and B-Class sub-compacts on the Japanese automaker's MC platform. The idea is to maximize the efficiency and output of Toyota's European plants, and could also include sharing development costs on each brand's next generation flagships: the Lexus LS and Mercedes S-Class. Daimler has dismissed the report as "speculation," while a Toyota Motor Europe spokesman toed the company line, only saying "It's part of our normal business practice that we regularly talk to other carmakers but there are no specific projects planned at the moment."
