The Edison2 concept car that won the $5 Unlike some of the cars in the contest, million prize was designed entirely using which were modified versions of small Solid Edge® software from Siemens PLM production vehicles such as a Prius and a Software. The team’s chief of design, Ron Smart Car, the Edison2 was designed from Mathis, had been using Solid Edge for scratch. Every component was evaluated about 10 years at the time Edison2 was and redesigned when necessary with an founded and, given the tight, two-year eye toward simplicity, strength and low timeframe for the X Prize, he wanted to weight. For example, its brake calipers, stick with the solution he had already used which usually weigh several pounds, are to design a number of successful race cars. less than one pound; lug nuts are 0.2 “One of the cars Ron designed using Solid ounces instead of 1 ounce.

All this took about two minutes. Without synchronous technology, this change could have taken days.” The rotor is part of an assembly, and because the parts in the assembly were interlinked, associated components updated automati- cally. “Without synchronous technology, we might have had to redesign the entire brake system,” he adds. The ability to make even fairly extensive design changes so quickly is allowing Edison2 to incorporate its concepts into a safe, comfortable car for the driving public in an amazingly short period of time. Another example is the work being done to strengthen the frame, which illustrates why fast design changes are crucial to get- ting the next-generation design even better. “As we move forward toward a car that will meet, pass and exceed FMVSS crash test standards, we’re developing the frame to absorb more energy as it hits things,” explains the chief of design,
