Mercedes boss Toto Wolff believes Ferrari currently has the strongest power unit but reminds that it is too early to judge engine performance. The Silver Arrows' team leader suggested that pre-season testing could be deceptive and it remains to be seen how much progress the scarlet team has made on the engine side.Speaking to German publication Auto Motor und Sport, Wolff said:“We feel that Ferrari have the strongest power unit at the moment. You have to see it in perspective, only one of the tests has been completed. Ferrari should not be praised too quickly. Winter tests can be deceptive.”Ferrari looked strong and reliable in Barcelona's first pre-season test. The Austrian executive director of the Silver Arrows team, however, was reluctant to make any predictions and was cautious to judge the Prancing Horse's engine gains.Scuderia Ferrari@ScuderiaFerrari𝗦𝗢𝗨𝗡𝗗 𝗢𝗡 Firing up for 2022 🤩#essereFerrari @Charles_Leclerc @Carlossainz5510:41 AM · Feb 3, 2022239833404𝗦𝗢𝗨𝗡𝗗 𝗢𝗡 🔊Firing up for 2022 🤩#essereFerrari 🔴 @Charles_Leclerc @Carlossainz55 https://t.co/tsZLpaggW1Overall, Ferrari racked up a total of 437 laps as a team, with Carlos Sainz being the busiest driver of the three-day test.

After taking a look across the field at Barcelona, however, one can expect the squad from Brackley to bring a significantly different W13 to the Bahrain test.
