WASHINGTON (AP) -- The government says it cannot explain areported incident of sudden, high-speed acceleration in a Toyota Prius on a San Diego, Calif., freeway last week.

The National Highway Traffic Safety Administration says in a
statement that it continues to investigate but may never know exactly what happened with the car.

The agency says its engineers are reviewing data from the Prius
owned by James Sikes to try to understand what happened with his
hybrid.

But so far, NHTSA (NIT'-sa) says it has not been able to find anything to explain the incident that Sikes reported.

Sikes called 911 last Monday to report losing control of his Prius as the hybrid reached speeds of 94 mph. A highway patrol officer helped Sikes bring the vehicle to a safe stop.
