Seat Leon Tdi Wtcc
In only its second WTCC race, the diesel-engined Seat Leon TDI came in first -- in front of its gas-powered Leon sibling. The diesel car only entered the series in July, yet it won three races and the driver was in championship contention up until the final race. BMW didn't need any more impetus than that to start planning its own turbocharged diesel engine program for the race series.
