Renault juniors Guanyu Zhou and Max Fewtrell will both take to the wheel of Formula 1 cars during this weekend’s Goodwood Festival of Speed.

Both drivers race in the F1 support paddock in Formula 2 and FIA Formula 3, and have previous experience of the 2012 Lotus-badged chassis from various demonstrations runs they have performed as part of the Renault Roadshow. They will share driving duties with current Renault F1 driver Daniel Ricciardo.

Zhou and Fewtrell were set to be joined by two-time Macau Grand Prix winner Dan Ticktum in Red Bull’s 2012 F1 car, until the Britain was dropped from its junior team last week. Red Bull Racing has confirmed to Formula Scout that Ticktum’s place will be taken by another former junior: Patrick Friesacher.

The 38-year-old Austrian was backed by Red Bull from 2001-’03, when he raced in International Formula 3000 for the RSM Marko team ran by Red Bull driver development boss Dr Helmut Marko. He picked up one win in 2003 but was dropped by Red Bull at the end of the season.

A fourth season with Super Nova and Scuderia Coloni brought another win, and earned Friesacher a F1 drive with Minardi for 2005. After his racing career ended, Friesacher has become a regular driver for Red Bull in various F1 demos.

There will be several other F1 cars in action at the Festival of Speed, with Paul Stewart – the British F3 race-winning son of Sir Jackie Stewart and founder of super successful Int. F3000 and British F3 team Paul Stewart Racing – demoing his father’s 1971 world championship winning Tyrell 003.
