Congrats to the Ganassi team.

By the way, I notice one of the 328i teams took second in the ST class in the BMW 200 sister race in the Continental Tire series on Friday at Daytona. Nice job.
I believe the use of the S62 is due to the availability and cost advantage of using a mass produced engine block. Remember the S62 is based on the M62.

Congrats to the team, watched it live.
