Toyota has denied reports in the German media which said it was to build cars sharing the Mercedes A- and B-class platforms.
The report suggested Toyota was considering the move to better utilise the efficiency and capacity of its European plants in the long-term.
It suggested that Toyota would start using the platforms in 2018, when the follow-up models to the upcoming A- and B-class models were introduced.
Mercedes and Toyota were also considering developing the new S-class and Lexus LS alongside one another to cut costs, according to the reports.
A Toyota spokesman in Japan denied the reports, and that they were without substance.
Daimler dismissed the news as “speculation”.
