It's been hard to judge winter testing form, and in truth only two things seem clear thus far. One is that Ferrari and McLaren are again the teams to beat, and the other is that Honda appear to have made little progress and are once again struggling.
Who really is leading the chase of the two top teams, however, remains to be seen. Among those who have regularly been near the sharp end at most recent tests are Williams, and the team have been more consistently impressive than several of the works outfits.
Things are most definitely looking up at Grove, although it remains questionable whether or not the team will one day come anywhere close to regaining the form that saw them win seven drivers' world championships between 1980 and 1997, and challenge for another as recently as 2003.
