My first time seeing this--is this new?

This article also clarifies the orbit:

He said it’ll be placed in “a precessing Earth-Mars elliptical orbit around the sun.”

Well, this onboard Roadster video would be cool, speculation or not....

SpaceX just sent an email: Elon's Roadster will be the Falcon Heavy test-flight payload.

The amount of power in the batteries of a Roadster is phenomenal. Once the last S2 firing is accomplished the computer triggers a relay connecting the Roadsters batteries into the S2. This could power the S2 for a very long time. With power the S2 can maintain attitude and communications back to Earth complete with video/images of the Roadster as it gets farther away from Earth especially an image of Earth and the Moon far in the background behind the Roadster would be priceless. A camera mounted as if your the driver looking forward out the windshield would be an amazing shot.

How about a couple mannequins strapped into the seats?

At a 200w continuous discharge the 200kwhr Roadster battery would last 41 days.

I wonder what sort of preparation will be done to the car to make it safe for the flight.  I would presume that all fluids would be removed to prevent any leaking and the tires would be cut open to avoid them blowing out when the pressure drops.

From a vibration standpoint highway driving is almost as stressful as most LV vibration testing. Its amplitude is not as high but the duration is a lot longer. The key in qualifying a design is the multiplier of amplitude (level) and the duration. Less amplitude but longer duration is almost as good as a higher amplitude and shorter duration.

As far as any of the car's electronics I would not power any of it up or even have it connected to the batteries. But then again it's Musk's rocket and car!!!

One of the items that may need removal is the shocks. They have a gas filled core and could cause problems.

Air conditioner 
Windshield washer fluid
Shocks
Tires
Brake fluid
Anything else?

The battery, electronics and electric motor(s) have liquid cooling systems (glycol.)

Don’t go disconnecting the air bags though. They could be needed...
This causes me to speculate, if the upper stage makes a course correction will the car need to indicate?
They’ll need the brake lights if the car is going to brake into orbit anywhere.
Power assisted steering could help there
GPS might get a little confused “Turn around and drive 36000km”
Air conditioner wouldn’t be needed but perhaps the heater though it’s going to be hard to heat the vacuum.

The article have been updated to say that the boosters will be attempting landings.

 The roadster could almost fit in the dragon trunk.

So what would fit in the Roadster’s trunk?

Thanks.

So replace the normal battery pack with a smaller set of space rated batteries not needing a cooling loop and some ballast/fill. Do a vibration acceptance of the battery pack and then mount to car. This greatly reduces any operating time but also decreases risk to the rocket. I am sure that it would not take much work to come up with a replacement space rated Tesla Roadster battery pack (a few kwh only not the 200kwh extended pack)

No need to remove the tires. Just take out the valve stems so they are vented to space.

Since it's an original roadster and only had a 53kwh pack I think it would need to have been replaced anyway.

A lot of Superman memory crystals. These guys made it to Elon’s Twitter.
