F1 Pre-Season Testing 2017: Tuesday Times and Analysis from Barcelona

Bottas had more success with mileage after lunch, completing 86 laps, on a day which saw the world champions trial some radical modifications to the sidepod of the W08.

Felipe Massa believes he had his hardest-working day ever in F1 on Tuesday when he completed the equivalent of two-and-a-half Spanish GPs to put Williams back on track in pre-season testing at Barcelona.

The Brazilian's best lap of 1m19.726s came in the final half-hour of running, deposing the Red Bull of Daniel Ricciardo, which led the way for most of the morning at Barcelona.

Massa drove 67 laps in Wednesday's morning session, second-most to Ferrari driver Sebastian Vettel, who had 82 laps and was fourth-fastest with a time almost a second-and-a-half slower than Massa's.

It was Vettel who logged the most miles during the morning, the German racking up 80 laps, 13 more than Massa as the next best.

Ricciardo was the man who set the early pace for Red Bull, producing one of the quickest times of testing so far on the soft compound.

Mercedes and Renault also continued to share driving chores between their respective drivers, with Lewis Hamilton and Jolyon Palmer running in the morning, and Valtteri Bottas and Nico Hulkenberg taking over in the afternoon.

"We can't take our eyes off them because they have been doing such a great job at the moment".

It was a frustrating day for Hamilton as he encountered balance problems during his 49 laps, an outing the three-time champion described as "not particularly" exciting. However, Vettel's impressive day will boost hopes of a competitive Ferrari package this year.

Palmer's morning was curtailed by a sensor issue on the Renault RS17 after he had posted only 15 laps.

The same can not be said of Stoffel Vandoorne or Jolyon Palmer.

"Based on this testing we can expect to have a few engine changes, but they (Honda) will have addressed this before the start of the season or at least quickly into the season", said McLaren Racing Director Eric Boullier.

Meanwhile, Pascal Wehrlein got his first taste of the new 2017 cars, having been forced to sit-out the entire first test, owing to an injury suffered in the Race of Champions crash he had in January.
