A close up of the W09’s rear end, including a nice view of the outwardly slotted and curved rearward Gurney tabs that surround the diffuser. Also note the thermal temperature strips on the crash structure as the teams monitor the exhaust plume’s interaction with it.

A rear end shot of the highly raked RB14. Note also how the main exhaust and wastegate pipes are upwardly angled, a trait shared by all the Renault powered teams. Red Bull’s version is not as aggressive as the ‘works’ team’s solution.

A close up of the C37’s rear end gives up lots of small details, including the outer section of the diffuser. This follows the feather style flap philosophy that Ferrari used for a number of years.

Mercedes’ new front wing as tested at the last day of the first test, which features a vastly revised endplate.

Having had temperature issues throughout the first test, McLaren made some hurried changes at the rear of the engine cover for the second test. You’ll note the two scorch marks behind the original bodywork outlet which are thought to be caused by its proximity to the heat generated by the turbo and exhausts. For this second test three more outlets have been added (just below Stoffel Vandoorne’s number) in order to help the heat be evacuated. This is after the team suffered a failure during the first test, when a clip failed and the exhaust became detached, scorching the bodywork and curtailing running.

A nice action shot showing the rear end of this year’s Haas. Note the use of the feathered flap style diffuser extensions on the outer section, helping to drive performance of this section harder.

The Sauber C37 fitted with a slow-motion camera on the nose which looks across at the front wing in order to monitor its deflection. Also note how the large ‘S’ duct inlet under the nose is perfectly aligned with the nose nostril’s exit.

The Sauber C37 plastered in flo-viz paint on one side of the car as the team looks for answers on how it aero is performing in order that it can continue to make gains. You’ll note it also has a substantial kiel probe array on the opposite side of the car to gather more data with.

Stoffel Vandoorne circulating in the MCL33 with kiel probes mounted in the airbox to study the airflow’s behaviour as it reaches the inlet. Another kiel probe array is mounted ¾’s of the way down the car to see how the airflow in that region is behaving.

Mercedes made an alteration to the central section of its diffuser for the first day of the second test, adding serrations on the trailing edge of the upper Gurney tab to help the airflow to overcome the tall flap above.
