Toyota will release the first mass-produced gasoline/electric
hybrid vehicle in the U.S. this year. Configured in parallel, the engine and
electric motor are connected to the drive train.
The company claims that the ratio of power provided by each system
is constantly controlled to keep the vehicle in its most efficient mode to
deliver a city/highway fuel economy rating of 52/45 mpg.
More than 35,000 already have been sold in Japan since its release
in 1997. However, the US and Japan versions are designed differently. Engineers
at the National Renewable Energy Laboratory (NREL) test drove the American
version and found it to handle very well in the Colorado mountains. "Because of
the steeply sustained mountain grades, Colorado provides excellent testing
grounds for an HEV (hybrid electric vehicle)," says a test engineer. "The
engines in the Japanese and American Prius are the same, but the American
version performs better because Toyota engineers have increased the engine speed
from around 3,500-4,000 to 4,500 rpm, providing higher engine horsepower." For

As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
Stratasys will be exhibiting two groundbreaking large-scale additive manufacturing technologies, as well as other new products, next month at the International Manufacturing Technology Show (IMTS) in Chicago.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
