Software-developed designs will be lighter and stronger, though

Car companies are looking for every possible way to eke out a few more miles per gallon these days, some of which involve high-tech combustion, and some others involve ultra-mild hybrid systems. But one generally accepted move is to remove weight, which helps both in efficiency and performance. General Motors has revealed a new technology that may become commonplace for shaving off a few pounds here and there, and the results are pretty freaky-looking.

Technologies like computer modeling and rapid prototyping have already changed the game when it comes to the design and development of passenger cars. But what about race cars, known for typically being further ahead of OEM development cycles? (The future of future development, if you will.) Many automotive innovations we use today trickled down from the racetrack. "IndyCar's technological heritage dates to the use of the first rearview mirror on an automobile during the inaugural Indianapolis

If you can dream it, you can build it.
