Background

Ferrari changed the livery on the F10's engine cover after the team was accused of promoting Marlboro cigarettes with its previous design.

The lead-up to the first practice session saw the media focus on several major upgrades various teams had introduced in time for the start of the European season. Mercedes abandoned the use of an airbox mounted atop the engine cowling, in favour of a rigid vertical rollbar and two pronounced air intakes directly behind the driver's cockpit. Virgin's solution to their problem of having a too-small fuel tank was to bring a longer chassis to accommodate a larger fuel tank and a brand-new fuel feed system that would allow them to run as light as possible during qualifying. The VR-01 was also given a "shark fin" engine cowling. However, owing to the volcanic eruptions in Iceland that had disrupted air travel across Europe at the time of the previous race, only one chassis was able to make it to Barcelona, to be used by Timo Glock. Following several dramatic engine problems that had affected both them and their customer teams, Ferrari were given permission by the FIA to modify their engines. In the wake of controversy that arose from accusations that their generic Marlboro "barcode" decal contained subliminal advertising, Ferrari removed all traces of it from their car for the weekend. Elsewhere, Hispania signed former Jaguar driver Christian Klien as a test driver, running him in the place of Karun Chandhok for the first practice session. Klien's FIA Super Licence – the licence that allows a driver to race in Formula One – was reported to have expired as he had not raced in over three years (his last appearance being at the 2006 Italian Grand Prix), which would have prevented him from leaving pit lane and taking to the circuit. Klien took part in the session, with reports claiming that his racing licence had been renewed just ten minutes before the session began.

Practice and qualifying

Michael Schumacher outqualified his Mercedes team-mate Nico Rosberg for the first time in the season.

The first practice session was incident-free, save for Sauber's Pedro de la Rosa falling victim to a gearbox failure. Lewis Hamilton and Jenson Button topped the timing sheets for McLaren, with Michael Schumacher experiencing a resurgence to finish third after a poor opening to his 2010 campaign. The German later admitted that the team's updates to the W01 had inspired more confidence in him. Local favourite Fernando Alonso was eighth for Ferrari, sandwiched between the Renaults of Robert Kubica and Vitaly Petrov. Heikki Kovalainen was once again the fastest of the new teams, his Lotus T127 finishing four seconds slower than Hamilton and less than two behind the Williams of Nico Hülkenberg.

Hülkenberg would later provide drama in the second session, when an off-track excursion at the exit of Campsa resulted in an impact with the wall that tore the front wing off. Toro Rosso's Jaime Alguersuari stopped on the circuit with just a few minutes remaining in the session, with the recovery truck hitting a bridge as it returned the stricken car to the pits. The session was topped by Sebastian Vettel, followed closely by team mate Mark Webber and Schumacher once again setting the third-fastest time. Alonso improved to fourth, while the McLarens of Hamilton and Button slipped backwards; Hamilton finishing fifth and Button ninth. Jarno Trulli supplanted team mate Kovalainen as the fastest of the new teams.

The third session was marked by separate incidents by Petrov and Kamui Kobayashi, both of whom found a puddle of standing water in the middle of the Repsol corner just minutes apart. Kobayashi survived unscathed, but Petrov spun and crashed. The damage to his R30 was extensive enough to warrant the team changing his gearbox, earning himself a five-place grid penalty. Similar penalties were applied to both Virgin Racing cars after the team failed to notify the FIA of changes to their gear ratios before the deadline, and to Hispania's Karun Chandhok, who replaced his gearbox.

Qualifying was a race to see who would place third on the grid as the Red Bulls of Webber and Vettel setting the fastest times in each of the three session. Webber went on to take pole position. Q1 saw the elimination of the six newcomers – a running theme throughout the season – as well as the Williams of Rubens Barrichello. Barrichello claimed he had been unable to understand his engineer while out on the circuit. The Circuit de Catalunya has a history of radio-related problems; during practice sessions for the 2009 race, Mark Webber reported being able to hear Spanish truck drivers talking to one another over CB radios. Lotus was once again the fastest of the newcomers, with Trulli and Kovalainen qualifying nineteenth and twentieth respectively, ahead of the two Virgins and the two Hispanias.

The second session was similarly themed, as Sutil, de la Rosa, Hülkenberg, Petrov, Buemi, Alguersuari and Liuzzi all fell away. Just four tenths of a second separated all but Aluguersuari and Liuzzi from making it into Q3. Elsewhere, Mercedes elected not to send Michael Schumacher out to join everyone else late in the session as they were confident his time would be enough to see him through to the final session. Ferrari committed to a similar course of action in 2009, with the end result being that Kimi Räikkönen was eliminated early on.

The final ten-minute period was once again dominated by Red Bull, with Webber to the fore. Hamilton edged out local hero Alonso for third on the grid, while Button narrowly missed out on putting his MP4-25 alongside his team-mate. Schumacher slotted into sixth place, followed by Kubica, Nico Rosberg, Felipe Massa and Kobayashi. Ferrari were later fined US$20,000 (in keeping with the sport's strict financial penalty rule) for an unsafe release that saw Alonso deployed directly into the path of Rosberg; the young German was forced to swerve in the direction of the pit wall – and came close to contact with it – in order to avoid a collision.^[5]

Race

Sebastian Vettel qualified second, but dropped to third place in the race due to brake problems.

The front-row starting Red Bulls of Mark Webber and Sebastian Vettel started well off the line, and even though they were challenged by Lewis Hamilton and local hero Fernando Alonso on the long dragrace to the first corner, they maintained their positions with polesitter Webber leading. Reigning world champion Jenson Button and seven-time world champion Michael Schumacher kept fifth and sixth, but there was light contact between Robert Kubica and Kamui Kobayashi which sent both falling down the order. Nico Rosberg in the second Mercedes was forced to take evasive action and ran onto the grass. Kobayashi's BMW Sauber team-mate Pedro de la Rosa had a similar altercation with Sébastien Buemi that resulted in a puncture for the Spaniard, while Buemi was demoted to last on the road. The incident would later morph into a greater problem for de la Rosa, forcing him to retire with accident damage. The other first-lap incident saw an early exit for Bruno Senna, his Hispania spearing into the barriers at the same corner as the Buemi-de la Rosa incident. Lotus's Heikki Kovalainen was the only driver who failed to start the race when his gearbox software attempted to select two gears at the same time.

The Red Bulls, especially Webber, slowly started pulling away from Hamilton, but the rate at which he pulled away was not as quick as one would have expected. The gap to Hamilton increased by two or three tenths of a second per lap, not by a full second as suggested in practice and qualifying. The first and only round of pit stops came shortly after lap fifteen, and a mistake by Red Bull cost Vettel four seconds, and a place to Hamilton. McLaren also did not have a perfect pitstop with Button, the result being that he came out behind Schumacher at the end of turn 1. Button was later critical of the German's swipe across the circuit to claim the position. He spent the rest of the race looking at the Mercedes' rear wing.

The sole surviving Hispania of Karun Chandhok was caught up in two separate incidents in the final sector of the circuit. The first saw contact between his car and Felipe Massa's Ferrari as the latter attempted to lap him as they negotiated the corner before the final chicane; Massa, who had been lacking speed all weekend, experienced a better-handling car with a damaged front wing. A pitstop would have meant dropping down at least two or three places for Massa and since the handling of the car wasn't hampered much due to the damage, the team took the decision of not bringing Massa in for a front wing change. The second of Chandhok's incidents saw Jaime Alguersuari chop across his front end at the same corner, knocking his front wing off. Chandhok was forced to pit, but retired a lap later with suspension damage caused by the collision; Alguersuari was given a drive through penalty for his efforts. His team-mate Buemi had been penalised earlier after rejoining the track in unsafe manner, just ahead of Jarno Trulli.

Williams gambled on a two-stop strategy for Nico Hülkenberg, a mistake that shunted the German driver down the order where he was caught up in a duel with a struggling Rosberg. Sébastien Buemi was the only other retirement, stopping on lap forty-four with hydraulics problems.

Lewis Hamilton had a wheel rim failure on the penultimate lap and crashed out of second place.

Local favourite Fernando Alonso took second place as a result of Hamilton's problems.

The race order settled down with Webber leading from Hamilton and Vettel. Alonso was fourth, ahead of the Schumacher-Button scrap which Massa also joined, with Sutil, Kubica and the recovering Rubens Barrichello in the Williams completing the top ten. On lap fifty-four, Vettel went wide at turn six, with a suspected front brake failure and had a trip across the gravel. This damaged his tyres, and he came in for inspection and also for a new set of tyres, which dropped him behind Alonso. It was soon evident that he was struggling with brake issues, and thus Vettel had to slow down for the rest of the race to nurse his brakes and finish the race. On lap sixty-five – the penultimate lap of the race – Hamilton lost second place when he suffered a left-front tyre puncture followed shortly by a blowout at turn three, which punted him into the wall, although far less violently than when a similar accident claimed then McLaren teammate Heikki Kovalainen at the 2008 race. He was classified as finishing fourteenth as he had completed 90% of the winner's race distance, his accident gifting second place to Alonso and allowing the fading Vettel back onto the podium for third. Vitantonio Liuzzi suffered a similar fate to Hamilton when his engine gave up on the same lap, the Italian stopping on the circuit.

Mark Webber won his first race of the season from pole position.

Mark Webber crossed the finish line first, becoming the tenth driver in ten Spanish Grands Prix to win from pole. Alonso finished second, with Vettel third and the unresolved Schumacher-Button scrap seeing the former World Champion home before the defending champion. Massa finished sixth, followed by Sutil, Kubica, and Barrichello and Alguersuari, who were a lap down. Jarno Trulli's Lotus was the first of the new teams to finish the race, whilst Virgin Racing notched up their first double-finish of the season, despite Timo Glock and Lucas di Grassi driving different versions of the VR-01. The final result meant that Button kept his championship lead going into the next round by just three points, while the same amount separated McLaren from Ferrari in the constructors' standings, with Red Bull only a further three points behind.
