Detroit-In a setback to use of so-called zero-emission vehicles, early March found General Motors recalling its 1997 Generation I EV1 electric cars and 1997-98 S-10 Electric Trucks. The company says the vehicles were produced with a charge port that may fail during charging. If this occurs, heat could build up within the port and a fire result. GM's advanced technology group says that although the small part can be replaced in the pickups, the more complex EV1 installation precludes repair. The notice said the company would assist in termination of the lease, and "discuss your immediate transportation needs."
Generation II, 1999 EV1s were not involved "due to their uniquely different charge-port design." The company says electric vehicles are still very important to GM.
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.
