GM had a big day in Braselton, Georgia, on Sunday.

Joining the trio of championships won by sister brand Cadillac, Corvette Racing took home four trophies of their own on Sunday. The No.3 C7.R shared by Jan Magnussen and Antonio Garcia took home the GTLM driver's championship, the GTLM manufacturer's championship for Chevrolet, along with the GTLM team championship.

Garcia and Magnussen, along with endurance specialist Mike Rockenfeller, also took home a second place finish from the weekend's Motul Petit Le Mans--joining a podium finish at Watkins Glen and victories at Sebring, COTA, and VIR.

"This championship was absolutely a team effort," said Mark Reuss, Executive Vice President, Global Product Development, Purchasing and Supply Chain. "The drivers, crew members and engineers were versatile and adaptable, and everybody on the No. 3 Corvette C7.R team contributed throughout the season. Jan and Antonio were consistent, smart behind the wheel and took advantage of opportunities when it mattered most. This was a hard-earned championship."

Since 2001 Corvette Racing has earned 11 Driver titles and 12 Team championships in North American. It's also the second consecutive championship sweep for Corvette Racing after Oliver Gavin and Tommy Milner won the 2016 championships in the No. 4 Corvette.

"This was a very hard year. We haven't had the strongest car this year. If we had a Corvette to finish third, fourth or fifth, we would finish first, second or third," said Garcia. "No matter the kind of car we had, we could gain two or three positions ahead of that. The Corvette Racing team did a great job all season with pit stops, strategy and preparation. No one put a foot wrong all season. Most of the time we stuck with the pace we had and let others make mistakes or apply pressure to our competitors. This was a very intense year but we maximized our results every weekend. Those fourth- and fifth-place finishes are where we got the most out of things. That's a large reason why we have won this championship."

"I'm super happy for the whole team to be in this position to take the green flag. It has been a hard season where we have had to make the most of sometimes bad positions, and I think that is what made the difference," Magnussen added. "We overachieved on the tough weekends and got the absolute most out of things when we needed. We also won the races we could. This is an absolutely fantastic feeling and a fantastic program to be in. Now on to the Manufacturer's Championship!"
