Tech gallery: How the Renault RS17 evolved throughout 2017

Renault's original rear wing design courted controversy straight out of the box, as its mounting pillar, attached to the DRS actuator pod, rather than the mainplane was deemed illegal.

During testing the team ran with an over-sized rear wing upper flap.

The team's sidepod airflow conditioners, later dubbed ‘Le Aerocat’ by the team owing to their feline appearance, is seen here.

The RS17’s bargeboards with their two slots in the footplate.

The wider bargeboard footplates now feature four curved louvre-like slots in them.

Two of the front wing options available to Renault, both with different flap tip options.

Changes made to the bargeboards footplate, include the shape and number of the louvres (arrowed).

New turning vanes were introduced with a double leading edge that change the flow around this portion of the car.

Detail of the front brake drum shows that the crossover section not only draws air across the face of the drum but also allows hot air from the brake disc to cross through it.

A look at the front brake duct assembly without the brake drum attached, note the blown axle which was introduced earlier in the season.

A large Gurney trim was fitted to the engine cover cooling outlet in order to aid in pulling airflow through the car.

During practice the team mounted this row of pitot tubes alongside the airbox spar to measure aerodynamic disturbance.

A kiel probe array was mounted behind the front wing in Abu Dhabi to collect data during practice.

The team ran with kiel probe arrays mounted behind the front wheels and three quarters of the way along the sidepod in order to gather data. Note a rearward facing camera/sensor is also mounted in between the front wing pillars.

The RS17 outfitted with some adapted wheel hub sensors to establish the loads present with the 2018 Pirelli tyres. Having used these sensors in previous years, they have plenty of historical data to reference them against.
