BOWMANVILLE — When the Corvette Racing team goes out Saturday for qualifying at the Mosport Grand Prix, fans will need a program to keep track of the changes on the once-powerhouse squad.

For most of its time in the American Le Mans Series, the Corvettes have been virtually unbeatable — especially so at Mosport, where the C6-Rs and the C5-Rs before them won an unprecedented four consecutive GT1 championships.

But with rule changes this season moving the Corvettes to the GT class, the wins have been few and far between. In fact, the team currently sits fourth behind class-leading BMW, with Porsche and Ferrari in between.

So Corvette Racing boss Doug Fehan decided to shake things up, breaking up the driving pairing for the No. 3 and No. 4 cars.

Olivier Beretta will move to the No. 3 Corvette C6-R, joining Johnny O’Connell, while Jan Magnussen will be reunited with former teammate Oliver Gavin in the No. 4 C6-R.

“Although racing is a technology-driven sport, there is also an important human element,” Fehan said.

“This change was made in consultation with all four drivers, and they are in complete agreement that this is the way forward.”
