McLaren's sporting director Sam Michael has taken a refreshing approach to his Formula One team's pitstop problems by promising that the beers will be on him once the crew average three seconds a stop.
Pitstops have troubled the British Formula One team all season and 2008 champion Lewis Hamilton suffered some glitches again in his two stops on the way to winning in Canada on Sunday.

With no time-consuming refuelling allowed during the race any more, mechanics aim to complete a tyre change in under three seconds while a driver in Canada can be in and out of the pit lane in 21 seconds under a 60kph limit.

Practice makes perfect

“Obviously we put a lot of effort into our pitstops, it's almost like a football team now, the way that we put the energy in,” Michael told Sky television at the Circuit Gilles Villeneuve.

“We were regularly doing two and half second pitstops all the way through practice this weekend.

“The challenge is for them to beat three seconds, and they've got a massive motivation because I've already offered the whole team a round of beers the moment they average a three second pitstop,” he smiled.

They failed to achieve that on Sunday but Michael said the times were still a big improvement. “The first stops were so good that both drivers didn't react in time so we lost reaction time because we dipped about five tenths quicker than we have ever done,” he said.
