Mercedes has a chance to clinch the Formula 1 Constructors’ Championship if results go their way in Sunday’s São Paulo Grand Prix.

However, with wet weather in the forecast, fans could be in for a chaotic race once the lights go out tomorrow.

Kimi Antonelli was fastest in FP2 on Friday, and was just 0.082 seconds off the pace set by McLaren’s Lando Norris during the first hour of practice, as Mercedes again showed strong one-lap pace over the first two practice sessions. That could bode well for the Silver Arrows during today’s qualifying session, as qualifying simulations show Mercedes is indeed the team to beat for pole position, with Red Bull and Ferrari just behind them.

Race pace is a much different story, as F1’s simulations indicate that while Mercedes is still in the lead, Red Bull is just 0.03 seconds off their pace, with McLaren 0.07 seconds off the pace, and Ferrari 0.10 seconds off the pace.

Adding more intrigue is a double dose of grid drops and weather. George Russell, Lewis Hamilton, and Max Verstappen are all taking grid penalties for new engine components, with Verstappen set to start the São Paulo Grand Prix from the back of the grid while Russell takes a five-place penalty.

And with Sunday’s forecast calling for rain, anything can happen when the lights go out … as is often the case at Interlagos.

So who will take pole position? Find out with us as qualifying for the São Paulo Grand Prix gets rolling at 1:00 p.m. Eastern on Saturday!
