The adventures of Pirelli at Silverstone have taken up most of the headlines in recent days in Formula 1 circles, but there are some interesting things going on in the background as the F1 circus moves rapidly to Germany for this weekend's grand prix at the Nürburgring.

Williams, which recently signed an engine supply deal with Mercedes-Benz, has announced a partnership between its engineering division and Nismo, Nissan's performance offshoot.

The two companies will work together in the development of high-performance road cars. Nissan hopes that the alignment with Williams will accelerate the growth of the Nismo brand around the world and improve the company's image by incorporating cutting-edge F1-based technologies and processes into its road-going models. This is a rather more wide-ranging deal than Williams' previous relationship with Jaguar.
