<P> At the French Grand Prix, Renault were expected to be faster than Ferrari, but Ferrari again had the advantage . Alonso ran third for most of the race, unable to challenge the Ferraris of Schumacher and Massa . However, a tactical switch to a two stop strategy enabled him to pass Massa and finish second . </P> <P> On 21 July 2006 the FIA banned the use of mass damper systems, developed and first used by Renault and subsequently used by 7 other teams, including Ferrari . Flavio Briatore claimed that McLaren had raised the issue of the system's legality with the FIA . The system used a spring - mounted mass in the nose cone to reduce the sensitivity of the car to vibration . This was particularly effective in corners and over kerbs to keep the tyres in closer contact to the track surface than they would otherwise be . However race stewards at the German Grand Prix deemed the system legal . The FIA announced its intention to appeal that decision and Renault announced they would not race with the system for fear of retrospective punishment if the appeal was upheld . Renault's performance at the German Grand Prix was one of their worst of the season; however, the team blamed blistering of their Michelin tyres rather than the loss of the mass damper system . The FIA International Court of Appeal met in Paris on 22 August 2006, to examine the appeal made by the FIA against the decision of the German Grand Prix stewards . The Court ruled that use of the device known as a Tuned Mass Damper is an infringement of Article 3.15 of the Formula One Technical Regulations . </P> <P> Points scored in the Brazilian Grand Prix secured the Constructors' Championship for Renault in 2006 . </P> <P> On 16 October 2006, Renault announced that the Dutch banking giant ING would replace Mild Seven as title sponsor for three years starting in 2007 . </P>
