Exhaust exits at several hundred MPH helping to pull air, causing a negative pressure, and push air out the diffuser---yes this will help with the aero.
As for the extra weight, no problem, they have to make weight to meet regulations. And power should be no problem as they have limitations to keep the revs and power in check.

This is one of the reasons our diffuser is designed the way it is and why we get such good results. :idea:

Looks like a bucket of greet paint hit him or something. ???

 

Looks like it is being rolled back into the garage. The car did suffer a power steering failure.

 

In a way, that's impressive. The car is light, so there is enough down force to necessitate the need for power steering.

 

Green PS fluid? Interesting.

 

So, back to my original thought of paint of some sort on the track...

 

This article from 2009 my shed some light on what we are seeing....

In short they say it is normal for the teams to spray on some paint when testing to see the real life airflow patterns.

 

FRANKFURT (Reuters) – Daimler AG's Mercedes-Benz is to gain full ownership of the racing team Mercedes GP by buying the 24.9 percent stake held by team principal Ross Brawn, Germany's auto motor und sport magazine reported on Wednesday.

The Mercedes Grand Prix racing team will continue to compete under Brawn's leadership, and cars and engines will continue to be developed and manufactured in England, the magazine said.

It said it obtained the information on the sidelines of pre-season tests in Valencia.

"We will only inform at a given time when there are facts," a spokesman for Mercedes motorsport told Reuters.

Mercedes bought a 75.1 percent stake in the team in November 2009 together with its partner, Abu Dhabi investment company Aabar, which bought a 9.1 percent stake in Daimler in March 2009.

The team emerged from the former Honda team after a management buyout led by former Ferrari technical director Ross Brawn. Honda quit the sport for financial reasons.

 

Flow Viz is a fluorescent powder suspended in a light oil (often paraffin). This is liberally applied by a spray gun to bodywork up stream of the area you want to investigate. As the car laps, the airflow spreads the non drying liquid back along the car, following the same path over the surface as the airflow. By then analysing the patterns the flow Viz leaves, you can see the behaviour of the airflow over the car. Details like direction and attached\non-attached flow can be observed. But this is only surface airflow and this is not the entire story when it comes to aerodynamics, so Flow Viz is only one solution for measuring aero on track.

 

It's almost as if they are creating one big porous wing.

 

Massa not having the best day in testing....

 

That must be the new "Back Off" feature. I'm guessing these didn't fit...
