DETROIT, Mich. (June 3, 2012) - Johnny O'Connell, of Flowery Branch, Ga., and Andy Lee, of Colorado Springs, Colo., defended their Saturday wins with a Sunday victories in the Pirelli World Challenge Cadillac V-Series Challenge at Belle Isle. The Cadillac and Camaro gave General Motors a weekend sweep on the temporary street circuit in the shadow of their world headquarters.

O'Connell's No. 3 Cadillac Racing Cadillac CTS-V won overall and in the GT class during the 27-lap Round Seven race, which was shortened to a 50-minute timed race after being slowed twice for 12 laps for full course cautions. The race finished behind the safety car, with the Cadillac averaging 66.719 mph in the 56.16-mile race.

O'Connell started from pole in the No. 3 Cadillac Racing Cadillac CTS-V, but lost the drag race from the standing start to the first corner to Lawson Aschenbach's No. 1 Privacy Star/Entrust Porsche 911 GT3. Aschenbach led the first 14 laps, including seven laps under the first caution caused when the No. 2 Hawk Performance Nissan GT-R made heavy impact with the wall.

Aschenbach pulled away from the restart with O'Connell in tow and the No. 9 K-Pax Racing Volvo S60 of Alex Figge and the No. 8 Cadillac Racing Cadillac CTS-V of Andy Pilgrim also giving chase. A bobble by Aschenbach in Turn 12 slid his Porsche wide, and O'Connell moved into the lead on lap 15.

O'Connell and Aschenbach pulled away in a two-man race, with the gap between the two fluctuating slightly as the pair worked their way through traffic. Aschenbach was on the bumper of O'Connell when Roger Miller's No. 23 Ford Mustang Boss 302S hit the tires in Turn 1, rolled onto his side door temporarily, and then settled back on his tires to bring out the final caution on lap 22. Miller walked away, but time expired before the car could be removed and the tire wall repaired to give O'Connell his second win of the weekend and third of the season.

"The day actually began after yesterday's race, going over what my car was doing," O'Connell said. "In yesterday's race, there were some things that I wasn't happy about, and looking at data with my engineer and making the right moves over night. In this morning's session, I pretty much focused on
