F1i brings you live coverage of the second day of the final in-season test from the Red Bull Ring.
Following his dominance of the Austrian Grand Prix, Mercedes' Nico Rosberg will drive the W06 Hybrid as he takes over from reserve driver Pascal Wehrlein, who topped the timesheets on the opening day. The 20-year-old is actually set to enjoy more track time as he replaces Esteban Ocon in the partially upgraded Force India.
Wednesday will see a new face in Formula One with reigning DTM champion Marco Wittmann scheduled to run in the Toro Rosso. This comes as a reward for his title success in the German touring car series last year.
Lotus reserve driver will succeed Romain Grosjean in the E23, while Daniel Ricciardo replaces Red Bull junior Pierre Gasly aboard the Renault-powered RB11.
Williams will have Valtteri Bottas back in the FW37 after test driver Susie Wolff finished bottom of the time sheets yesterday. Following his heavy crash during last Sunday's Austrian Grand Prix, Fernando Alonso will be on deck for McLaren-Honda.
Ferrari test driver Esteban Gutierrez is taking over from GP3 racer Antonio Fuoco whose 'childhood dream' debut in the SF15-T ended up with a crash at Turn 1 on the opening day of testing at the Red Bull Ring.
After narrowly missing out on points because of brake issues last Sunday, Felipe Nasr will slot in behind the wheel of the Ferrari-powered C34 to close Sauber's test in Austria.
