Is Ferrari hiding its true pace?

With 3 days of testing now complete, it seems like Red bull is the fastest car. But testing means nothing if we compare the teams in terms of lap time, but testing demonstrates the problems related to the power unit.

Dominant Red bull.

RB19 was the most successful car for Red bull. And they continued to develop the car from RB19 not really changing the concept of the car. Although reports suggest that RB19 has 90% changed aerodynamics compared to its predecessor. Red bull looked more stable than other teams while the reigning champion Max Verstappen pushed the car. According to Helmut Marko, Red bull has found a solution to help Max and Perez both drive the car according to their driving styles. The red bull seemed dominant in testing as well with Perez clocking the fastest time, Perez's lap time was 2-tenths quicker than last year's pole lap of Charles Leclerc.

Ferrari

Ferrari didn't seem like it was focusing much on lap times rather they were mainly focused on trying different setups. According to motorsport Italy Ferrari did their lap times with 30-35kg more than Red bull. A source closer to Red bull reported that Red bull knows where Aston Martin and Mercedes are in the pecking order, but they don't know where Ferrari will be. Either Ferrari was sand bagging or was just focused on different configurations to help their drivers get comfortable with the car. The SF-23 is a front limited car due to their front wing not generating downforce, and their main title contender likes a car that has a lot of front end. But Charles Leclerc is really good at adapting the car and pushing to the limits. The SF-23 is more than one second quicker than its predecessor. The main talking point of the Sf-23 was its efficiency and tire wear. Efficiency was its a much better car than last year's. It has gained almost 10km/h of straight-line speed with efficiency which was the major problem of the F1-75. Tire wear was also a major problem of F1-75 which it seems is inherited in its successor. But that was mainly due to the slimmer rear wing Ferrari ran in its 3 days of testing. And having more fuel onboard causes stress on tires ultimately resulting tire degradation.
