Year after year we say it, and year after year it's true... to finish first, first you have to finish.

With no significant overhaul of the regulations it isn't exactly surprising that that there were no serious reliability issues over the three days of testing.

That said, for the most part reliability was very impressive.

Amidst all the talk of long runs, short runs, fuel loads and the rest, the main factor is - as we saw with Ferrari last year - it's no use having pace if your car isn't going to last the distance.

Consequently, AlphaTauri, who had a pretty dreadful 2022 and are now understandably subject to deep and meaningful speculation within the Red Bull empire, will be pleased with what they achieved over the three days.

While Yuki Tsunoda was the sixth fastest driver overall, and fourth on the C4, teammate Nyck de Vries completed the second highest number of laps.

Indeed, when you consider that he had less time in the car than the man who completed the most (Alonso), the Dutch youngster had a very busy time of it, as did fellow rookie Logan Sargeant.

With Alonso doing the lion's share of the testing it comes as no surprise that Felipe Drugovich completed the least number of laps, however, worryingly, joining the Brazilian-Italian at the wrong end of the table are the McLaren pair, Lando Norris and Oscar Piastri.

With that in mind, with just 312 laps to its tally, compared to 456 for AlphaTauri and 439 for Williams, McLaren will be approaching the season opener with understandable trepidation.

Of then three main title contenders, Red Bull completed 413 laps, compared to Ferrari's 417 and Mercedes 398.

Since it supplies for of the teams it comes as no surprise that Mercedes tops the engine reliability chart, though with just two teams the Honda RBPT unit is looking formidably strong.
