Sauber C29 F-Duct

With barely two weeks having passed since the season-opening Bahrain GP, Sauber has managed to copy McLaren’s radical “F-duct” system and fitted its own version of the system to its C29 cars.

In two weeks?

Incredible! Apparently this system took McLaren about two years to come up with!

The duct idea helps stall the rear wing at high speed when the driver closes off a vent in the cockpit and was given the green light by the FIA before the Bahrain GP.

Appearing to be mounted to the left-hand sidepod of the C29, with rules restricting changes to the chassis tub under the homologation rules, it is not known how the drivers can manipulate the air flow through the car.

Another contrast to McLaren’s design is that the air channelled through the C29 appears to be blown out onto the main profile of the rear wing, rather than the upper element as is believed to happen on the McLaren MP4-25.

The team intends to test the system in practice for the Australian GP before deciding whether to run the unit in qualifying and the race.

"We have no testing, and this is the first opportunity we have to try it. We have to test it, make sure it works and then decide if it is raceable or not. We just have to have the patience to test it properly,” said Sauber driver Pedro de la Rosa.
