The No.25 BMW was fast back in 1975 when it won here at Sebring, now in 2015 the new No.25 showed equally strong pace in the opening practice session for the Mobil 1 Twelve Hours of Sebring.

Dirk Werner put the retro-livered Z4 on the top spot with a lap of 1:59.496 ahead of a pair of Porsches driven by Richard Lietz and Bryan Sellers.

Early session leader Jan Magnussen finished the session fourth fastest for Corvette Racing. Only 2/10ths of a second covered the top five cars in the GTLM class.

In the prototype division Joao Barbosa set the pace for Action Express Racing – finishing fastest at 1:52.485. He topped the two Ligier P2-style prototypes driven by Oz Negri (Michael Shank Racing) and Nic Jonsson (Krohn Racing).

Other class leaders included Colin Braun for CORE autosport in PC and Mario Farnbacher in GTD aboard the No.23 Porsche.

The session was interupted by one red flag when Jeroen Bleekemolen’s GTD-class Viper stopped on track and had to be taken back to the pits.

Cars are back on track at 2:15pm today for their second practice session.
