"Once again in Barcelona, as was the case at the first test in Jerez, we had quite cool weather and a sprinkling of rain, but the teams were still able to get through a considerable testing distance, with all the compounds apart from the full wet tried out, although there was very little significant running on the intermediate," said Paul Hembery.

"Montmelo is well known as a technical and wide-ranging circuit, which makes it an ideal test venue to investigate every aspect of tyre behaviour.

"It's still too early to draw too many conclusions about the year ahead, but the lap times already indicate that the cars are even faster this year, with many of the testing times comfortably inside last year's pole position.

"The teams were able to work through quite a varied programme, including pit stop procedure, in order to acquaint themselves with the characteristics of the 2015 Pirelli range, and match them to their new cars. This work will continue during the next test in Barcelona, which is the final opportunity for the teams to prepare their cars before the first grand prix of the season.

"At this time, we're also pleased to announce that as was the case last year, Pirelli will be the Title Sponsor of the Spanish GP in May, and the Hungarian GP in July."

In addition to the usual 2015 tyre range, teams were also able to try out a prototype medium at Barcelona, which is being assessed by Pirelli for development purposes. Any teams that had not used their allocation of ‘winter hard' prototypes at Jerez were also allowed to carry them over to Barcelona.

Each team is allocated a total of 110 sets of tyres for testing purposes throughout 2015; down from 135 sets last year.

Fastest laps and tyre choices per day

Day 1: Maldonado (Lotus) 69 laps - 1:25.011 (Soft)
Day 2: Ricciardo (Red Bull) 143 laps - 1:24.574 (Soft)
Day 3: Maldonado (Lotus) 104 laps - 1:24.348 (Supersoft)
Day 4: Grosjean (Lotus) 111 laps - 1:24.067 (Supersoft)

After four days of testing a total of 3134 laps were covered, with the performance gains in evidence compared to last year's Spanish Grand Prix pole time of 1:25.232s. This year's Pirelli tyres feature a new rear construction, which distributes temperature more evenly and also contributes to a reduction in lap time.
