Next Monday, the Formula 1 season will kick off with the first official four-day test session at Barcelona. Today we offer a first glimpse of what the cars that will be testing at the Circuito de Catalunya will look like. One of the most highly anticipated machines for 2019 is most definitely the Red Bull Racing RB15. Fitted with the Honda power unit, this is the first Red Bull Racing car not powered by a Renault-built engine in over a decade. In addition to the new engine, the team also has a revised driver line-up with Max Verstappen joined in 2019 by Pierre Gasly. The latter's old team, Scuderia Toro Rosso, already revealed their new STR14 yesterday. Sharing the driving duties for the Red Bull junior squad this year will be old hand Daniil Kvyat who makes a return to the team and newcomer Alexander Albon.
Unquestionably set to star at the sharp end of the grid will be the Mercedes-Benz W10 EQ Power+, which like the RB15 already briefly ran for a filming session this morning. It is the latest in a line of Grand Prix cars that has won the World Championship every year since 2014, so the W10 will start the year as the car to beat.
Over the last few seasons, Renault has gradually moved up the field and with the R.S. 19 unveiled yesterday, the French team aims to score regular podium finishes. To give the final push, Renault managed to pry Daniel Ricciardo away from Red Bull Racing to join Nico Hulkenberg.
At Williams, there is a new livery as shown on this mock-up FW42 courtesy of new title sponsor RoKIT and also a new driver line-up with Robert Kubica finally making a return to F1 racing. He is joined by the highly regarded Mercedes-Benz junior driver George Russell, who makes his F1 debut.
