Having worked in the automotive and truck industries for many years, I can provide some insight. To develop a true and efficient electric vehicle as produced by Tesla requires re-engineering the platform from the bottom up. The vehicle is designed around the technology and needs of consumer, light weight, alternative materials, and new technologies, amongst other. Many existing auto makers are having difficulties producing this type of product, as they rely on existing infrastructure and parts designed for older fossil fuel applications.
An example in comparison,
If you went to a fast food restaurant and ordered a salad, what would you receive? You would get the lettuce and tomatoes as used on the burger, chopped slices of cheese as used for cheese burger, and a salad dressing likely made from the vegetable oil used to make the fries with vinegar added.
Is this really what you wanted?
This typically translates into extra weight, poor aerodynamics, and existing parts that don’t adapt well to newer platforms, and limited efficiency. Many fossil fuel vehicles were produced from platforms required to support the weight of engine and supporting systems, with respect to location. Due to these systems, aerodynamics and weight are always a problem, and production of many parts to support this platform type, cost is an issue. This is clearly observed by some automakers attempting to produce electric vehicles with limited success, miles per charge, and excessive price with respect to quality and efficiency. Quality and efficiency says everything.
Do you want a vehicle developed around an older platform and infrastructure, or developed to meet customer needs? Do you want the salad from the fast food restaurant? Or are you looking for something different.
It’s an easy decision, and why I support this company.
