TESLA CROSS COUNTRY CONCEPT

Wildlife depends upon soils, plants, air and water to survive. When any of these natural environments are altered, dependent wildlife will be affected. ORV (Off Road Vehicles) have negative impact on natural environments and Eco systems such as erosion, soil compaction, bank stability, water quality, destruction and loss of vegetation, aquatic losses, and wildlife impacts. There has to be more sustainable ways of Off-Roading in order to protect the natural environment and its habitat.






NATURAL ENVIRONMENT

Off-Road cars have negative impact on the natural environment. The high levels of noise can damage animals' hearing sense and cause frantic behavior, ear bleeding and temporary loss of hearing. Moreover, the gasoline and engine oil consumed by these cars can leak into the soil, water streams, rivers and lakes which can contaminate and damage the environment. With off road cars exceeding 80 million visitor days in national forests, it is likely that tens of millions of gallons of gasoline and motor oil contaminate the natural environment every year. 
Further more, the off road cars' heavy weight causes soil compaction and disruption, which can decrease water infiltration, increase runoff and cause severe erosion problems.






PROBLEM SOLVING

Electric cars can reduce the noise emission and disturbance of wildlife since electric motors are significantly quieter than gasoline engines. Also, Electric vehicle do not use pollutant and hazardous chemicals such as gasoline and motor oil, thus protecting the natural environments from contamination. Moreover, the design of a simplified light weight corporeal structure (Monocoque Chassis) can help with the weight reduction of the vehicle in order to reduce the soil compaction and erosion, efficiency and range. 







LIGHT WEIGHT DESIGN

In order to reduce the weight, this design incorporates a light weight structure that is integrated and morphed into the interior and exterior of the vehicle which can simplify assembly, reduce weight while keeping its rigidity. The structure is made of a Carbon Fiber cabin tub, which draws inspiration from the skeleton structure of animals to create a rigid and lightweight design. The cabin tub sits on an Aluminum platform that adds more rigidity, increases durability and houses the batteries and motor assembly. 







AERODYNAMIC DRAG

The overall range and efficiency is a defining part of the design of an electric vehicle. While a lightweight structure can help increase range, aerodynamics play an important role in energy consumption. Since Electric cars do not have an engine in the front, the design and proportions of the car can be utilized and changed to reduce drag coefficient and increase the mileage. 






AERODYNAMICS

Most off road cars have bulky design and that would be problematic for an electric vehicle because battery range is affected by air resistance. Since there is no engine in the front, the passenger cabin can be moved forward, creating a longer and smoother windshield canopy which starts closer to the bonnet. Moreover, narrow intakes in the front can be used to reduce accumulation of high pressure air and channel that air from under the bonnet, or from the sides of the car and exhaust that air cleanly from the back which reduces air turbulence and drag.
