Tuenti Racing's Pepe Oriola set the pace in free practice one at the World Touring Car Championship's maiden visit to Slovakia
The Spanish racer set his time at the Hans Roth-designed Slovakia Ring early in the half-hour session, before running off the road in a late effort to improve his benchmark.
The 17-year-old has claimed an Independent's victory in each round this season, and was again on form to hustle his Sunred-prepared Leon to a time of 2m14.434s.
Lukoil Racing's Gabriele Tarquini finished 0.198s adrift of Oriola in his similar Leon WTCC. The Italian held fourth during much of the session, but eclipsed James Nash's Arena Ford Focus for the runner-up position two minutes prior to the chequered flag.
Marrakech reversed-grid pole-sitter Nash, who is running without 30kg of penalty ballast for the first time this season due to changes to the car's suspension, secured third. The Milton-Keynes racer's Arena team-mate Tom Chilton sat out the session with fuel pressure sensor difficulties.
Chilton has a single session of practice available before qualifying this afternoon, as no testing took place at the Slovakia Ring on Friday. The Reigate driver can call on circuit knowledge from his brother Max, who has tested extensively at the venue as part of his GP2 preparations.
Rob Huff was the highest placed of this season's dominant RML factory Chevrolet drivers in fourth, some 0.820s behind Oriola. Team-mates Alain Menu and championship leader Yvan Muller followed in fifth and seventh respectively. More is expected of the Chevrolet men in free practice two.
The top-six was completed by Tarquini's Lukoil Racing team-mate Aleksei Dudukalo. The Russian is aiming to recover ground after a torrid preceding meeting in Marrakech.
The session was red-flagged after 12 minutes when former Formula 1 driver Tiago Monteiro stopped out on track. His Tuenti Leon was recovered to the pits and later rejoined the action.
Hungarian rookie Gabor Weber suffered an early incident to find the gravel in his Zengo Motorsport BMW.
