The Saudi Arabian GP will be hosting its second F1 race this weekend. After what was a slightly chaotic first race of the season in Bahrain, the F1 circus reaches Saudi Arabia with a fear of heading into the unknown.The track layout is still new to the F1 teams, and so are the technical regulations. In what will be just the second race of the season, there are quite a few key questions that need to be answered heading into the race.In this piece, we're going to talk about some of the key questions that need to be answered heading into the second race of the season.#5 What will be the pecking order?BWT Alpine F1 Team@AlpineF1TeamDouble points and P5 in the Constructors' Championship. We go again in Saudi! Allez Alpine 3:39 AM · Mar 22, 2022126243Double points and P5 in the Constructors' Championship. We go again in Saudi! Allez Alpine 🙌 https://t.co/9FXZhB9JI0Most of the competitive running and testing that we have seen so far with these new regulations has been in Bahrain. We have only seen the cars attack one particular layout so far and based on that, we had a certain pecking order last season.Coming to the Saudi Arabian GP, however, we have a very different layout on our hands. With the regulations still new, we can expect different cars to have different characteristics. Will those characteristics yield a change in the pecking order? We cannot count that possibility out.#4 Can the Mercedes customer teams recover?McLaren@McLarenF1Onwards and upwards! 10:52 AM · Mar 22, 202211635280Onwards and upwards! 🙌 https://t.co/bQskVj7yZ0The Bahrain GP was particularly brutal on the Mercedes customer teams. If we look at the final classification of the race, then the last 6 running cars were all Mercedes customers.Now the entire blame for the fall in the competitiveness of these teams cannot be put on the power units. Aston Martin suffered from excessive porpoising, while McLaren has had its issues with overheating brakes.Coming to a new track, will we see these teams recovering from an early dip in form? Let's wait and watch.
