However it was Matějovský who won the event, thanks to the qualifying points.
Their results meant that Czech Republic earned a total of 32 points in the Nations Cup and moves into a 3-point lead over Germany.
The leader of the Super 2000 category arriving in Slovakia, Fernando Monje, failed to repeat his dominant performance from the opening races in Monza and so it is Peter Rikli who leads the S2000 class by one point.
Other winners of the day were Kevin Krammes (Ford Fiesta in S1600), Andreas Pfister (SEAT León Cup in Single-Make Trophy) and Nikolay Karamyshev (Honda Civic) in Super Production.
Rounds 5 and 6 of the ETCC will be held at the Salzburgring in Austria on May 20th.
