That is just 1" higher than
That is just 1" higher than the Model 3 is now (6.5" vs. 5.5") so I seriously doubt that it will take much engineering other than using different springs. All economical cars work to reduce aerodynamic drag on the car, especially on the highway. I had Chevy Volts and now have a Cadillac ELR and they both have low air dams/skirts that scrape on speed bumps and steep driveways. The rubber skirt on the Volt was only 4" off of the ground, and Chevy actually did a free swap for customers because so many were scraped off in normal driving. I've driven in southern India and the last thing that you are worried about is scraping on speed bumps, as driving conditions and traffic is a challenge, to say the least. But it is a good thing that they have such an easily fixed issue to be in compliance with local needs. The greater challenges will be getting the price of Tesla models down to more affordable levels, and building out the Supercharger network in India.
