Sustainable Design - Automobiles - Unifed Standards

In the world of computers, there are some standards : Voltages, ATX power supplies, hole locations for motherboard mounting, power connectors, RAM or memory types and slots, buses and other connections like USB, Ethernet, 802.11 etc.   Automobile manufacturers should and could have the same approach. Since the 1990s, and even earlier, automobiles have been considered mature products. Little has changed in the past 100 years ranging from an internal combustion engine, lights, steering wheel, hydraulic brakes and air inflated tires. If there were a limited number of categories of vehicles with respect to weight and usage, the interchangeability of parts would be a step towards sustainability. It would improve manufacturing processes by making the industry more competitive, while allow engineers and technicians to develop solutions which would make our vehicles safer and more efficient. Better quality materials would also make the cars last longer.

An automobile with an internal combustion engine has many components which shouldn't vary from one vehicle to another :

• Brakes : A hydraulic system where a piston with a large surface is depressed with low pressure resulting in high pressure at the brake calipers and wheel cylinders  If the cars were known to carry a maximum amount of weight / passengers, at a given speed, the brakes are to be designed to be able to absorb a given amount of energy.  Make a single size of caliper, brake pad and rotor that would fit all cars in that same class. Standards for the brake fittings would also be appreciated. ( in the case of electric motors, regenerative brakes are another case altogether. I can't wait for them to go mainstream. On that note, autonomous cars would also be appreciated. ) Protected brake lines which are made of copper-nickel, would ensure that they last more than 10 years in areas where salt accelerates corrosion.
• Tires : There are standards when it comes to tires and wheels, however the variety is superfluous. If there was a norm for all sedans to have 380mm (15") or 355mm(14") wheels, the tire size could be set for all cars - width, aspect ratio. At the time being, using a tire that is larger or smaller, thus a change in circumference/diameter, can result in a damaged automatic transmission. More vehicles using the same size tires and wheels would mean less tires and wheels being scrapped.
• Suspension, steering rack etc. : There have been countless hours spent on redesigning the wheel. Some changes to the components can improve the ride of a car, yet for most the changes are not that noticeable. Springs and struts could be of standard size and fitting, likewise for many of the other components of a steering rack.
• Electrical components : This is quite easy. A simple start would be a numbering system for fuses. There are already many standards when it comes to the light bulbs on vehicles. Electric locks, window regulator motors, audio system connections etc. could also be the same across all vehicles.
• Disposables : Spark plugs, oil filters, PCV valves, thermostats, air filters- same sizes and locations ( right/left )  for all vehicles could also be designed within a certain class. 

There are some standards for items like fluids, such as motor oil, coolant, brake fluid and automatic transmission fluid. Were standards be to extended for other parts, automobiles would seen as a technological triumph improving our lives.
