Heifer fuel

Unlike most people, when Michael Doyle drives past a herd of cattle grazing in a field, he doesn't see future tenderloins or T-bones. He sees fuel.

Retracing Steve McQueen's Los Angeles in his Jaguar XKSS

In 1958, Steve McQueen bought this Jaguar XKSS from a local TV personality who kept it parked in a studio lot on Sunset Boulevard. McQueen cajoled his wife Nellie into writing a check for $5,000 -- today around $40,000 -- and became the third owner of XKSS chassis No. 713, a car that had originally been imported a year earlier by Jaguar North America.

Chrysler recalls Jeeps for fire risk

Chrysler has decided to recall 2.7 million 1993 to 2004 Jeep Grand Cherokee and 2002 to 2007 Liberty models for a potential risk relating to the fuel tank placement between the rear bumper and rear axle. The recall is initiated 15 days after the automaker originally denied a request following a National Highway Traffic Safety Administration investigation. On June 4, one day after NHTSA's finding, Chrysler rejected the request in a media statement, stating the NHTSA's initial conclusions are based on “incomplete analysis of the underlying data.” Chrysler said the impacted models met or exceeded all applicable requirements of the Federal Motor Vehicle Safety Standards, including the ones pertaining to fuel system integrity.
