Alfa Romeo Racing’s 2019 Formula 1 car has been officially revealed ahead of the start of the first day of pre-season testing at Barcelona

The renamed squad rolled out its latest F1 challenger - dubbed the C38 - in the Circuit de Barcelona-Catalunya pitlane prior to the first day of track action getting underway on the opening morning of pre-season testing. 

Alfa Romeo has retained a similar white-and-red livery scheme to last season, having first appeared on-track during a shakedown event last week running a Valentine’s Day themed paint job. 

Five Storylines to look out for in F1 2019

A distinctive front wing design that first broke cover during the filming day has been retained, marking an eye-catching and innovative interpretation of the new aerodynamic regulations with a concept that differs from its rivals. 

Former Ferrari driver Kimi Raikkonen heads a new-look driver line-up for Alfa Romeo, with Scuderia protege Antonio Giovinazzi returning to the team he made his grand prix debut with two years ago for his first full F1 season. 

The team is looking to continue its upward trajectory after securing eighth place in the 2018 constructors' championship under its former Sauber guise. 

Haas also officially presented its 2019 F1 car in the Barcelona pitlane, with track action at the Spanish Grand Prix venue beginning at 0900 hours local time (0800 GMT) as the opening pre-season test gets underway. 

Raikkonen has been handed first duties of getting behind the wheel of Sauber's 2019 F1 car on Monday.
