Following the Bahrain Grand Prix, Martin Whitmarsh discusses the race and Vodafone McLaren Mercedes plans for the three week gap before the next race in Spain

Lewis usually makes excellent race starts, but that wasn't the case in Bahrain. What happened?
"It was a procedural error - his engine was on the incorrect setting and that led to the anti-stall procedure kicking in, so he was swamped by everyone else as he tried to get away."

He has admitted that he forgot to push the correct button...
"Yes, but as a team Vodafone McLaren Mercedes doesn't habitually blame its drivers in public. Is the procedure clear? Is it simple enough? We have to look at all the details."

People are accustomed to celebrating Lewis's successes, but this just didn't seem to be his weekend. His demeanour remains very upbeat, though.
"I think he's disappointed, but he's very strong-minded. He had a reasonable qualifying run, but a practice accident meant Friday wasn't his greatest day, and nor was Sunday. He won't lose confidence, though. He believes in himself and knows he can get the job done. He'll go away, rebuild and come back stronger in Spain."

Lewis switched to a one-stop strategy after he ran into the back of Fernando Alonso on lap two. Have you determined the cause of the accident?
"It's an interesting situation for those of us on the pit wall, because you see an incident such as that and have to respond in terms of pulling him in, getting the car repaired, looking at fuel load options that might help him recover and so on. At the time we didn't actually know how it all unfolded, however. People come up immediately after the race and ask, "So, was he brake-tested?" and you can't answer. It is assumed that you are being evasive, but in truth you simply don't know. It was only when I went into the engineers' room and started looking at the details that I realised Lewis's upper front wing had disappeared about two seconds before the accident, so he suddenly lost downforce. We haven't analysed why that happened but we suspect the structure had been weakened by previous contact. To be fair to Lewis it could have broken of its own accord, but that has never happened before so contact is the most likely cause. There's certainly no evidence that Fernando did anything wrong. The impact damaged other elements of Lewis's car apart from the wing - he just had to cope as best he could."

Heikki drove very well again, but his afternoon wasn't entirely without problems.
"No. For a reasonable proportion of the race his car was wounded by a very bad flat spot, after he locked up on the opening lap. By the time he pitted his front right tyre was worn down to the canvas. For his second stint, with hindsight, we were maybe on the wrong type of tyre, but we went long and heavy just to try something different. It didn't benefit us, but there was no harm done either.
"Heikki set the fastest lap, which added a positive sheen but also underlined that we didn't unleash the car's full potential throughout the race. It's a further illustration that you have to get every element of the weekend absolutely right."

Heikki has been with you for three races and has scored a hat trick of strong points finishes. How do you assess progress so far?
"In all he has been with us for 11 weeks and he's just getting stronger and stronger. The feeling within the team is that we still haven't seen the best of him. Lewis thinks as much, too, and that's good because he knows he'll have to raise his game. Both Heikki and Lewis have learned a lot in the 20 grands prix they've done. They are deeply ambitious - and I know teams always claim their drivers love each other - but everyone at Vodafone McLaren Mercedes can sense the mutual admiration that exists between them. They want to beat each other but they are open and fair, so there are lots of positives."

There has been a tendency for people to view the world championship as a two-way fight between Vodafone McLaren Mercedes and Ferrari, but BMW Sauber is emerging as an ever more consistent force.
"You have to congratulate BMW Sauber. I know we underperformed a little bit, but their cars were very strong. It's clear that this is going to be a tight, exciting championship - and that's good for the Formula 1 audience. You have to go to each race with a strong car, you have to set it up and operate it properly and the drivers have to race it well. If you fall short in any of those areas, you're going to slip back into the pack."

The series now heads to Europe after three flyaway races. What's next on the schedule for Vodafone McLaren Mercedes?
"We've got an aero test coming up in a few days and then we're back on track next week in Barcelona, which will be our first proper test for five weeks. It's unusual for teams to make great progress during a period of no testing, but I'm confident we are about to make a big step forward. That said, we recognise and respect the strong job Ferrari and BMW are doing and don't suppose they'll be standing still."
