U.S. auto safety regulators have launched an investigation
into electric sports car maker Tesla Motors Inc's (TSLA.O) luxury Model S sedan
after three car fires in six weeks, and Tesla announced it is raising the
vehicle's ground clearance.
Tesla shares fell in premarket trading on Tuesday following
the news but they were up 3.5 percent in early-afternoon dealings.
The U.S. National Highway Traffic Safety Administration has
opened a preliminary evaluation of the risks associated with highway debris
striking the underbody of the 2013 Model S, the agency said on its website on
Tuesday. (r.reuters.com/cys74v)
