Battery Powered Car Design

Battery Powered Vehicle
Your task is create a vehicle that is battery powered that travels 10 feet in a straight line as quickly as possible.  You may not use any preassembled parts (i.e. wheels on an axle) although you may premade wheels.  You cannot use four identical wheels. 
You will begin your project with a short response that includes your initial plans for the vehicle and should also include drawings (including color) for the shape and overall design.  You should include at least one completion milestone and have Mrs. Pennington check your response before you begin work.
