decided to sleep through FP1 and get up for fp2. Seems some interesting stuff happened, Hamilton's failure not so much a failure as a smaller issue. Anyone following testing would have picked up on a lot of software issues. For testing they would gradually turn up the software shutdown safety limits as they wanted to push the engine harder and eventually beyond what they hoped to run throughout the season. I can imagine both these things combine to the point where software could cause quite a few unexpected shutdowns throughtout the year.
This may have been an intended one that saved them from the engine blowing up 3 laps later, or could have been an accidental bug in the software, if an engine blows with 5 laps to go, okay, if an engine shuts down because of a safety setting that is wrong and ruins the end of a race... I'll be disappointed.
Lap times were pretty god damned tame, 1:27.2 fastest in FP1 last year, wasn't at all expecting them to max it out but they are 5 seconds off, they dropped to 1:25's in FP2 last year, and 1:27 in Q3 after rain in Q1. Though I presume different tracks will show changing difference in times vs last year, Bahrain fastest in testing was pretty close to Bahrain pole from the previous year, the pretty much 7 second gap is huge.
My guess would be times currently are completely miles off FP3/q1-3 times, but the real question is who will improve the most. Could be that say Merc move up to a 1:28, Mclaren stop at a 1:30 and Red Bull stay at a 1:32, or they all move up together and this is the same order. Not sure anything can be known in terms of times/speed yet, not even sure qualifying will be a true reflection, maybe a couple teams scared of breaking the car will be happy to just use qualifying as further testing. Stick on some harder tyres, fuel up and stay out the entire session at relatively low speeds just to get more laps done.
