Good point, Rob. As CAD and CAE become more of an integrated process as opposed to siloed tools done by different groups within engineering, there are bound to be design efficiencies. The real benefit, here, though was upping the number of prototype designs explored without upping the number of physical prototypes having to be built. Time saver and money saver.
Interesting article, Beth. That's a nice way to increase possibilities in design -- to do it with computers instead of physical prototypes. While the process may not have saved design time in this case, I would imagine it would inevitably save time as this practice becomes part of the standard design process.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
