With the Halfdome Asset you can easily render Cars into an HDR.

I noticed there are no classic Half-Domes for Blender. Half-Domes are very commonly used in the Automotive industry usually for 360 visualizations of cars. 

Any classic equirectangular HDR will work. 

Included:

• Halfdome Mesh & Shader
• 1x Automotive HDR
• Carpaint Shader on Monkey

not included:

• the mustang

10% of the income will go straight to the 'Blender Development Fund'.

Have fun with it and greetings from the automotive capital Germany,
