Only one thing has been consistent about Ferrari's season, and that's the peaky nature of its performance. Having left pre-season testing as favourites in the eyes even of Mercedes, the SF90 has only shown that kind of pace throughout one weekend, Bahrain, and even then other problems conspired to cost it victory.
Coming to Barcelona, the big question was could Ferrari recapture it's testing form? With the accelerated introduction of its new-specification engine, as well as aerodynamic upgrades including a modified front wing, rear endplate tweaks and an elongated engine cover fin, there is hope of a step forward.
But perhaps more significant than that question is that, regardless of whether it's faster or slower than the Mercedes, does it feel like it did pre-season? This was something Vettel was keen to discover.
