Alfa Romeo fans love to go on and on about beauty and soul, but we’re talking about a modern-day Formula One car here. We’re just lucky this isn’t the year of the
penis nose with those. Sauber unveiled their Alfa-branded F1 livery today, and it’s okay. It’s not a gorgeous 4C in F1 car form. It’s just okay.
This isn’t next year’s Alfa Romeo Sauber car yet, but just the 2018 livery shown on a car. We’ll see the car itself much later.
Sauber also
announced today at their press event in Italy that reigning Formula 2 champion Charles Leclerc will be replacing Pascal Wehrlein for 2018, driving alongside returning driver Marcus Ericsson. This is Ericsson’s fourth season with the team. Ferrari’s former third driver Antonio Giovinazzi will now be Sauber’s third driver—in for some testing and first in line to drive if one of the main two can’t race.
I agree that it's boring but I like the idea of teams revealing their liveries separate from the car. I think people want to see the livery almost as much if not more than the car itself.
