We had a busy 3 days of testing that showed for the most part remarkable reliability for all the teams ! Overall comparing test times, drivers' conversation and such Mclaren seem to be the preemptive favorites heading into the new season, and 1st race in Melbourne ! That is followed by in my opinion Mercedes and Ferrari. Mercedes seem to have made great gains, showing a very solid platform and covering the most miles/laps out of all the teams in 458 ! RedBull unlike the last 2 years seem to be a little out of sorts, they had issues throughout the test and covered the least number of laps with 304. Both drivers also did not get the amount of testing miles they wanted.
