Diesel fumes linked to illnesses

DIESEL exhaust fumes have been linked to a range of illnesses and long term health conditions from heart disease to diabetes. The fumes are a complex mixture of gases and fine particles containing contaminants including microscopic particles less than one-fifth the thickness of a human hair and small enough to penetrate deep into the lungs and bloodstream. Over a long period of the time, exposure to the fumes can raise the risk of potentially deadly blood clots and increase the risk of stroke by narrowing the arteries that carry blood to the brain.

2011 Audi R8 GT, an AW first look

Pricing has not yet been revealed, but given the extent of the changes to the new two-seater, buyers should expect a hefty premium over the R8 V10's $147,000 price tag when the GT goes on sale in North America.
