Land speed racing has many ties to fuel efficiency. The better streamlined your car is, the less power you need to go a certain speed. In land speed racing, this translates to higher speeds with less power. For fuel efficiency, this means less fuel at the speed you drive.
One of the most innovative cars in racing is a series of cars called the Nebulous Theorem. They are built with nearly no ground clearance and extremely minimal frontal area. The NebII has set records at 360mph with a turbo 1.5L engine. (About 700hp). Power needed to overcome aero drag cubed is proportional to speed. So, if you assume 700hp to overcome drag at 360mph, only 3hp is needed at 60mph.

ok thats cool I wont need to go over 70 mph, mostly 50 and under
so Im hearing different choices from you guys, some high some low , i can go either, so whats the pros and cons of each? I see both on the net, remember Im only going 50 mph 15 miles round trip to work
