Up at the front, Tarquini's cause was being aided by Priaulx's inability to find a way around Porteiro, the Spaniard matching the efforts of the SEAT ahead but never getting close enough to look like challenging. Eventually, Priaulx found a way past with a superb move up the inside of the first corner on lap nine, one that seemed to catch Porteiro unawares.
However, while the reigning champion had no problems cruising up to the back of Tarquini, the Italian was faultless in the Leon's weaker bends, before simply pulling out a gap again down the home straight. While Priaulx was rarely ever more than a second behind his sparring partner, he would not find a way past.
Nonetheless, after such a tough start to the weekend, a fifth and second place finish for Priaulx still puts him third in the standings and makes him the leading
BMW, much to the frustration of the Schnitzer duo.
It was Tarquini's race though, the former European Champion scoring his third win for SEAT in the process. Behind Priaulx, Porteiro held of a late challenge by Jorg Muller for third, while further back, early points leader Yvan Muller resisted Farfus' desperate attempts to snatch fifth off him. The final points position were claimed by Rydell and Gene, the latter fighting his way up from 12th on the grid.
After their abysmal start to the season in race one, Chevrolet attempted to hit back in the second race, but Alain Menu and Nicola Larini fell just short in 10th and 12th respectively. Rob Huff meanwhile was forced to retire with suspension damage again after being tagged by Tiago Monteiro on the first lap.
Elsewhere, Olivier Tielemans scored his second Independents Trophy victory of the day for reigning champions Wiechers-Sport, the Dutchman holding off Proteam dup Sergio Hernandez and Stefano D'Aste for the win.
