Final answer:
The design team presented Concept 2, a solar and wind energy-powered vehicle, and Concept 4, an ethanol-powered alternative fuel vehicle, as two options for LTC Green Vehicles, aiming at sustainability and practicality for commuters.
Step-by-step explanation:
The two options for LTC Green Vehicles that were researched by the design team involve vehicles powered by alternative energy sources to remain environmentally friendly and practically adoptable by commuters, while staying compatible with existing infrastructure.
The first option, referred to as Concept 2, includes a commuter vehicle powered by a combination of solar cells and wind energy. These energy sources charge batteries at municipal charging stations, which in turn power the vehicle's wheel hub motors, equipped with regenerative braking systems.
The vehicle itself is a small, three-wheeled car with an enclosed cabin for two passengers. The second option, Concept 4, is similar but differs in its energy source, utilizing ethanol as a fuel to run the engine of the small, two-seater vehicle.
