Mercedes motorsport chief Norbert Haug insists that the new version of the Concorde Agreement should continue to include a ban o🎉n the use of customer cars in F1.

Currently, teams are responsible for designing and building their own chassis and aren't able to simply buy a chassis 'off the shelve🌞' from a rivaওl outfit.

The issue of customer cars is one that has been discussed at length for some time, but as tal🍃k🌸s about the revised version of the Concorde Agreement continue, Haug said it was important that the rules stayed as they were for the food of the sport.

"Generally speaking, I think Formula 1 has a heritage and a history," he said during the latest FOTA Fans Forum. "I just do not think that a Lotus should be a McLaren or a HRT should be a Ferrari; this would be the case if you had customer cars. It was and i💫s in discussion but we also need to respect 💮the likes of, for example, the very successful Williams team and the independents in Formula 1 like Sauber.

"I just think they have the right to build their own car and I think they're quite interested in building their own car - this is a very, very important ꦚpart of Form♌ula 1."

Haug added that customer car🅺s would also not necessarily be a cheaper option for smaller teams like Marussia and HRT - wh💞o are currently racing to prepare cars for the season ahead.

"At first glance you might think it is less money but, if you carefully go through it, it's not nece🐼ssarily less money - it's not the ideal solution," he said. "If it was the ideal solution, I think everybody would have chosen thaꦍt path already."
