Williams consolidate their position as F1 racing’s third-best team, but after finishing the previous year with the second-quickest car they are frustrated to slip even further back from the imperious Silver Arrows and to be overhauled by a resurgent Ferrari squad. Two podiums each for Valtteri Bottas and Felipe Massa are the high points in a year in which the FW37 looked impressive on quick circuits but uncomfortable at slower ones.
Combination of excellent chassis, Mercedes power, and Bottas-Massa driver pairing sees team return to form. The FW36 is frequently the only real challenger to Mercedes works cars, and though wins remain elusive, finish third overall after podium appearances at eight out of 19 races.
Start their campaign with high expectations, but Renault-powered FW35 a huge disappointment and both Maldonado and rookie team mate Bottas spend season racing largely outside of the points, scoring just twice en route to the team finishing ninth overall.
Switch to Renault power helps boost competitiveness, with Maldonado taking Williams' first win since 2004 in Spain. But inconsistent qualifying (from Senna) and multiple incidents (from Maldonado) hamper progress and team slip backwards as season progresses.
Worst season in team's history, with poor reliability and mediocre pace. Score just five points and make it through to Q3 on only three occasions. Technical director Sam Michael leaves, to be replaced by former McLaren man Mike Coughlan.
Mixed early fortunes, both drivers occasionally making Q3 and lower end of points. Results much improved by mid season, with Barrichello fourth in Valencia. Hulkenberg takes surprise Brazil pole and team finish sixth overall. Hulkenberg dropped for Pastor Maldonado for 2011.
Fail to capitalise on being one of just three teams with innovative double diffuser at season's start. FW31 proves consistent and reliable, but never quite has podium pace. Announce switch from Toyota to Cosworth power for 2010.
Season starts well with a podium for Nico Rosberg in Australia, but then fail to match development pace of rivals. Second place in Singapore the year's highlight, but drop from fourth to eighth in the final standings, with 26 points.
The FW29 proves much more reliable than its predecessor, and the team record just seven retirements instead of 20. Alexander Wurz retires ahead of season finale and is replaced by Kazuki Nakajima, who retains the seat for 2008.
Disappointing season sees team finish eighth in standings. Cosworth-powered package shows early promise, including fastest lap at Bahrain season opener, but challenge quickly fades. Twenty DNFs, with best results two sixth places for Mark Webber.
Finish fifth in standings then bid farewell to engine partners BMW and Nick Heidfeld, who, after scoring his maiden pole, misses last five races through illness/injury. Best result Monaco, with both drivers on podium.
Ralf Schumacher misses six races after fracturing spine in Indy accident. Replaced by Marc Gene and then Antonio Pizzonia. Team ditch radical 'walrus' front wing after disappointing start to season. End it on high with victory in Brazil. Fourth in standings.
Dramatic improvement in form in the second half of the season with four race wins. Finish second to Ferrari in the standings after losing final-race showdown.
