So...
Mercedes: Bottas is 0.6 seconds faster than last year and Hamilton 0.2 seconds. That gap is enormous, if they were at Spa they'd be almost a second faster than everyone else.
Red Bull: Verstappen is 0.1 seconds slower than last year and Albon is 0.3 faster than Gasly's time. Verstappen starting on the mediums could give him a late-race advantage on low fuel.
Ferrari: Leclerc is 0.9 seconds slower than last year and Vettel is 0.6 seconds slower. Where to begin...they've really dropped the ball, assuming the new car is any better they just need to think damage limitation for these two races; stay out of trouble and grab points whenever possible.
Racing Point: Perez is 0.9 seconds faster than last year and Stroll 0.8 seconds. Look's like they've bridged the gap to the front-runners, or at least to Red Bull, but to be fair that car does look almost exactly the same as last year's Mercedes.
McLaren: Sainz is 0.5 seconds faster than last year and Norris 0.4 seconds. McLaren have evidently stepped up as well, and that was fantastic from Norris.
Renault: Ricciardo is 0.4 seconds faster than last year and Ocon 0.1 seconds slower than Huelkenberg's time. Ocon is a bit rusty obviously but they seem a little better.
AlphaTauri: Gasly is 0.4 seconds faster than Albon's time last year and Kyvat is 0.9 seconds faster. A major improvement over last year, slightly nulled by everyone else's improvements
Haas: Magnussen is 1.1 seconds slower than last year and Grosjean 0.2 seconds slower. Haas is a perfect example of how not to Formula 1.
Alfa Romeo: Raikkonen is 0.9 seconds slower than last year and Giovinazzi 1 second slower. They were really strong here last year so this does not bode well.
Williams: Russell is 0.7 seconds faster than last year and Latifi is 0.5 seconds faster than Kubica's time last year. Russell is killing it and that's a perfectly respectable first qualifying from Latifi. They've closed the gap, we just need to see if they can fight.
In short, Mercedes, Racing Point, McLaren, AlphaTauri and Williams have all improved while Haas, Alfa Romeo and Ferrari have catapulted backwards.
