Tarquini was exactly a tenth behind Menu, beating the bamboo engineering Chevrolets of Michel Nykjaer and Alex MacDowall which were both within a second of the pace.
Norbert Michelisz was this time the best of the BMWs in eighth, ahead of the SEATs of Darryl O'Young and Aleksei Dudukalo, while Mehdi Bennani completed the top ten in his BMW.
Muller was again fastest in the second session, but only managing a 1m23.124s. Huff was 0.369s behind, with Menu 0.659s shy.
Tarquini was eight tenths off the pace, with Tiago Monteiro going well in his Sunred-powered Leon to finish fifth and only nine tenths from Muller.
MacDowall and Nykjaer were next up, while Tom Boardman impressed with the eighth best time. Fellow Toms Coronel and Chilton were ninth and tenth.
