NHTSA probing coolant leak in Porsche 911?

In another embarrassing failure to understand what they're supposed to be regulating, the NHTSA has announced that they are investigating a “coolant leak” in Porsche 911s that were built with the GT1 engine block between 2001 and 2007.

Porsche is developing a new four-cylinder engine set to power entry-level model

High-ranking officials at Porsche's Weissach research and development center in Germany have confirmed that engineering work is progressing on a four-cylinder horizontally opposed gasoline engine, details of which were first revealed by Autoweek earlier this year. The new boxer unit--which is earmarked to power a new mid-engine, entry-level model that insiders describe as a spiritual successor to the iconic 550 Spyder--looks set to become an integral part of Porsche's future model plans. Insiders suggest it will also be offered on the third-generation Boxster and the second-generation Cayman later on in their respective model cycles.
