Engine Failure Forces Paul Newman Out of Car Race DAYTONA BEACH, Fla. (Reuters) - Actor Paul Newman's bid for a second 24 Hours of Daytona title ended eight hours into North America's only round-the-clock endurance race Saturday.

Newman's Porsche, running in the GTU classification -- one of five divisions racing simultaneously -- blew an engine and officially retired at 9:35 p.m. after completing 225 laps.

The 75-year-old actor and longtime race car driver was part of the winning team in the GTS category in 1995.

The Academy Award winner was not driving when the engine blew. Teammate Michael Brockman was behind the wheel.

Newman did start the race and moved his Porsche into 31st place overall by the end of his one-hour shift. The car, also driven by Brockman, Gunnar Jeannette, Michael Laver and Brazil's Pierre Kleinuburg was running as high as 22nd overall before going out.

Defending champion Dyson Racing's Ford Riley and Scott was in complete control at the 10-hour mark, holding an 11-lap lead over its nearest rival, a Dodge Viper from the GTO class. Driven by team owner Rob Dyson, Elliott Forbes-Robinson, Max Papis and Briton James Weaver, the car had completed 313 laps as of 11:20 p.m.

Last year's winning car was the only entry from the elite SportsRacing division in the top five.

All three Ferrari 333 SPs developed early engine problems.

Two entries from Cadillac, making its first racing appearance in 50 years, were strong starting, at one point running 1-2. But they fell off the pace with wheel problems.

The Cadillac driven by Andy Wallace, Butch Leitzinger and Franck Lagorce was still second in the elite category but it was running seventh overall and 16 laps behind Dyson.
