Lotus driver Romain Grosjean set the fastest time on Day 1, but could not carry the same pace through afternoon and dropped down to third at the end of the day. But on Day 2, after 95 laps on board the E21, the French driver clocked the fastest time by a comfortable margin of almost one second. The Frenchman said “My feeling in the car is good and it was great to be at the top of the times. Even if it doesn’t mean anything during testing, it’s still good to be at the front.” Grosjean will now hand over the E21 to Raikkonen for the remaining two days of testing at Jerez.

The problem stricken Mercedes team had to pull out their W04 once again after a rear brake problem pitched Lewis Hamilton’s car off the track and straight into the barriers, resulting in him not being able to get enough tracktime on his debut onboard the W04. The damage to the front wing and suspension of the car were minor compared to the rear brake problem and the team said there was a fault in the hydraulic brake line connecting to the right-rear caliper. The car was pulled out of the test session for the rest of the day. An electrical problem on Rosberg's car which led his W04 to burst into flames on Day 1 and a brake trouble on Hamilton's car meant that after two days the Brackley based team could complete only 29 laps in the first two days of testing. 

The Sahara Force India driver Paul di Resta once again impressed and bettered his time from Day 1 by recording the second fastest time on board the all new VJM06. The British racing driver handed over the car to the team’s simulator driver James Rossiter for the last one hour before the end of the day. The team did a lot of aero work on the VJM06 and made set-up changes on the car that not only helped Di Resta clock the second fastest timing but was also helpful in gathering data on the tyre performance.

Torro Rosso driver Daniel Ricciardo was the surprise package in the two days of testing as he was fourth fastest on Day 1, and  despite the STR8 stopping on track earlier in the morning he managed clocking the third fastest time on Day 2. Red Bull driver Mark Webber was the busiest driver throughout the day completing a century of laps. The Australian clocked the fourth fastest time. Webber swapped places on the time sheets on Day 2 with his compatriot but it was the satellite team that proved to be faster. Nico Hulkenberg placed the Ferrari powered C32 in a strong fifth place. The German spent more time familiarizing himself with the car and tried different tyre compounds to gather data. The ex-Force India driver declared himself pleased with his new office space.

Sergio Perez placed seventh in his debut onboard the McLaren MP4-28 and spent a lot of time acclimatising himself with his new office. The team run him through a programme of mechanical and aerodynamic adjustments to familiarise himself with the MP4-28 and completed 81 laps of running. 

Ferrari driver Felipe Massa was unable to record as many flying laps as he would have liked since the team was testing the aerodynamic and exhaust package on the new F138 and wanted to gather as much data as possible on performance of these new components. The Brazilian could only manage to bring himself up to 8th place on the time sheets. 

The team spent most of the time gathering inputs on the aerodynamics and exhausts due to which the Brazilian was unable to set out flying laps having spent most of his time doing speed runs and in analysing various aerodynamic solutions. He explained, “All the changes to the car took longer than planned, but in the afternoon, I managed to do three long runs which were very important in order to understand which direction we need to follow in the coming days.” Massa will be testing for another day at Jerez before he hands over the F138 to Pedro de la Rosa. The Maranello based team will be doing most of the aerodynamic tests and speed runs before Fernando Alonso gets behind the wheel at the second pre-season test in Barcelona.

Reigning World Champion Sebastian Vettel and 2009 World Champion Kimi Raikkonen are yet to hit the track, and Day 3 will have all eyes turning to see what the two champs have in store. By then Mercedes team should have sorted out their teething problems with the car to have a smooth testing day. Mechanical and electrical problems during testing are common, but come as blow to a team which is under pressure to compete with the front-runners specially after recruiting a championship winning driver like Hamilton.
