Soon drivers will be able to plot eco-friendly routes. Engineers from Audi of America Inc.'s California Research Labs are working with three California universities to reduce CO2 emissions through intelligent interactions between the driver and the car. "The path between two points can be measured in distance, but it can also be measured in the amount of carbon dioxide that our vehicles emit," says Daniel Rosario, Audi's manager of Connected Vehicles. When drivers choose a route with the lowest CO2 emissions, they can improve fuel efficiency by 20 percent. Rosario notes the technology exists today — it just needs to be integrated into an "intelligent vehicle network."
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
