#77 and #78 is very creative and thought provoking. I see a tachometer in #77 and a steering wheel in #78. I like how you were able to use different colors and the potential for that in your designs are very appealing. But #76 is the preferred logo from my team. We can see the G, the i, and a steering wheel. Even tho the G is flipped - I think the logo can get away with it because it shows a steering wheel in the design as well as the G and i.
