F1 test round-up: Ferrari gets the glory, Mercedes gets the miles

Only Ferrari and Red Bull ran the rule over the rubber Pirelli feels is 0.5-0.8 seconds per lap faster than the next softest tyre in its range, the super-soft.

LAWRENCE BARRETTO: How good was Ferrari's start?

The ultra-soft runners occupied four of the top-six places in the combined times for the week, with Ferrari duo Vettel and Kimi Raikkonen top and third respectively, split by Force India's Nico Hulkenberg.

On the super-soft tyre, Hulkenberg finished just 0.3s adrift of Vettel, and a third of a second up on Raikkonen.

From fourth to sixth it was a similar story as for the top three, with super-soft runner Sergio Perez in his Force India fifth quickest, sandwiched by Red Bull duo Daniel Ricciardo and Daniil Kvyat's ultra-soft times.

Pirelli surprised by early ultra-soft use

Overall, Ferrari led the way on three of the four days, with Hulkenberg denying the Scuderia a clean sweep on Wednesday.

Raikkonen was forced to settle for third on that occasion as newcomer Haas and Romain Grosjean sprang a surprise by nudging into second, although do not read too much into that.

As for Mercedes, it opted not to set any kind of eye-catching time. Instead Lewis Hamilton and Nico Rosberg ground out the laps (675) and miles (1952) in search of reliability.

No other driver or team came close, with Renault's debutant Kevin Magnussen next up behind the Mercedes pair with 264 laps.

On the constructors' front, Toro Rosso - with a 2015 Ferrari power unit in the STR11 - fared well as it managed 447 laps, but still 227 shy of the German manufacturer.

Ferrari managed just half the distance of Mercedes - 1952 miles compared to 1020 - and barely conducted any set-up work, according to Raikkonen.

McLaren, following its woes last season, started off on a firm footing, until a hydraulics leak in the MP4-31 for Jenson Button on Wednesday, and coolant leak for Fernando Alonso on Thursday, severely curtailed the car's running.

Newcomer Haas will be pleased with the amount of mileage it covered, amounting to just over 800 in total, finishing ahead of McLaren and Manor.

With rookie pairing Pascal Wehrlein and Rio Haryanto on board, Manor managed 254 laps, which could have been more but for spins for Haryanto on each of his two days, costing him and the team valuable track time.

Bringing up the rear was Jolyon Palmer in the Renault, his week in stark contrast to team-mate Magnussen as a software issue on his first outing on Monday and turbo problem on Tuesday restricted him to just 79 laps in total.
