do you think we will only get a normal filter for vent or we will get something like Model X - Pollution free medical grade HEPA filter?
Normal filter like Model S.
Hopefully Tesla has learned their lesson on that and we will have a normal filter. People shopping for Camry-priced cars are not going to be happy replacing a $250 cabin air filter.
Since the 'firewall' is greatly reduced in size, by being pushed further forward, underneath a steeply slopped frunk hood, I doubt there will be room for a giant HEPA filter on the Model ☰.
One thing I liked to see in the Model S was a more advanced air handling system, but it is forgiven as you can't stack up risks to the sky with your first model.
Model 3 promises vast improvement thanks to the elimination of the dash cluster, but nothing really revealed yet. I would pay good money for the better air handling and filtration system.
I believe that the Model ☰ will use very creative location and shaping of air bag systems, rather than having a bulky dash.
