Mercedes has gone back to its standard nose configuration for the rest of the Brazilian Grand Prix weekend, after evaluating the impact of an S-duct type concept on Friday morning.

The team was the focus of technical intrigue at Interlagos after Nico Rosberg and Lewis Hamilton's cars were fitted with a S-duct style panel ahead of first practice.

The raised nose section featured an open vent to channel air, and is understood to be part of an evaluation programme that Mercedes is considering for its 2016 car.

The current dominant Mercedes does not feature an S-duct, which teams like Red Bull and McLaren run, but such a device could appear on its challenger next year.

The tests on Friday will deliver valuable input in to design concepts for 2016, with the team considering raising the height of its nose section.

Hamilton and Rosberg tried back-to-back testing with the vent having been sealed off on one of the cars in first practice, as the team conducted its aerodynamic evaluation.

The team also used flo-vis paint to evaluate what impact such a change of airflow would have on the cockpit area.

Neither Hamilton nor Rosberg featured the S-duct vent for second practice and it is thought the team will keep to its more standard configuration for the rest of the Interlagos weekend.
