My entry for this challenge is a 3-wheeled lightweight roadster designed for high performance yet economical. It would be powered by an Inline 4 cylinder gasoline engine (likely a large motorcycle engine with a lot of torque). It would be constructed of all lightweight materials including fiberglass and carbon fiber to keep it below 900 pounds to maximize performance and fuel economy. It features independent double wishbone suspension on the front wheels and a paralever arm suspension/drive train combination on the rear wheel. Based on a similar design, you could expect upwards of 180 horsepower, a top speed exceeding 150MPH and experience 0-60MPH in less than 4 seconds. No fancy 3D rendering has been used for display, just pure SketchUp goodness. See link below for blog entry and image gallery: #3d_challenge_105 #roadster
