The Jetta TDI Cup will make its first appearance in Iowa this weekend at Iowa Speedway in the fifth race of the VW Jetta TDI Cup on Saturday, September 20 at 5:30 p.m. The race will mark the beginning of a demanding schedule for the final half of the series that will have the drivers racing three consecutive weekends until the finale at Road Atlanta. The 30 young drivers will face a full day on Saturday with practice, qualifying and the race all taking place on the same day, a challenging first in this inaugural season of the clean diesel series. David Jurca, Federal Way, Wash., currently leads the series as the top points earner thus far. Via media.vw.com
