The data on the ownership of automobiles continues to climb as the influence of industrialization continues to spread. Along with the increase in the automotive industry comes an increase in fuel consumption, greenhouse gases, and resource usage. This in return increases the demand and cost of fuel and resources. Even though car manufacturers do put in the effort to minimize the negative consequences of automobiles and increase its efficiency, measures to achieve sustainability are rarely implemented [117]. With the introduction of nanotechnology, new opportunities to make the industry safe and sustainable have arisen. The combination of car engineering and nanotechnology has influenced change in each part of the car. For instance, the improvisation of nanomaterials such as carbon black and silica in car tires results in lower rolling resistance, abrasion resistance, friction, and extended tire life and safety; decrease in weight; and overall a superior performance. In addition, brominated isobutylene‐co‐para‐methyl styrene elastomer‐based nanoclay has proved to increase the air retention of tires by 50% in comparison with halobutyl rubbers. CNTs have also been used to enhance the tensile strength and tear strength of the tires [118]. In terms of thermal performance, nanofluids have the potential to improve the cooling rates of the engine by increasing efficiency, decreasing the weight, and making the thermal management systems more simple. They can also be added to fuel additives, coolants, engine oils and greases, and brake fluids [119–121].
