The air intake for the engine is placed in a nacelle between these rollover hoops, while turbocharged cars use a large duct placed to the left side of the cockpit.
In late 2006, a new chassis for Fernández Racing's Acura team was built which included slight upgrades, leading to Lola terming the car B06/40.
A similar situation would occur in the LMS, with Barazi-Epsilon's Courage Competition outdoing the Ray Mallock EX264, which had one win.
For the 24 Hours of Le Mans, Ray Mallock would again take the LMP2 victory, with Intersport, Binnie and Chamberlain-Synergy also participating.
For the 2007 season, Intersport would move to the LMP1 class with a new chassis, while Fernández Racing would join the series with an upgraded B05/40 for use with the Acura Le Mans project.
Ray Mallock, Horag, Binnie and ASM Team Racing for Portugal would all remain in the Le Mans Series, all running with the 2007 upgrades.
