Progress slows, as the C38 proves frustratingly inconsistent, even with the experienced Kimi Raikkonen at the wheel. Nevertheless retain P8 in the standings, 22 of their 57 points coming at the season’s eventful penultimate round in Brazil.
Team Principal Fred Vasseur steers his squad on a surprisingly rapid upward path, their Ferrari-powered C37 proving increasingly competitive, particularly in the hands of rookie star Charles Leclerc, who scores 39 of their 48 points – a total almost 10 times their 2017 tally.
Another tough campaign ends with just a five championship points. However, the mid-season arrival of Frederic Vasseur as team principal, followed by an Alfa Romeo title sponsorship deal for 2017 plus the signing of Ferrari protege Charles Leclerc, all bodes well for a brighter future.
Lack of funding in the first part of the year means limited development, leaving the team woefully off the pace. Matters improve after mid-season arrival of new owners, and Felipe Nasr scores the only two points of their campaign at the penultimate round in Brazil, giving them a last-gasp top-ten finish in the final standings ahead of Manor.
Recover to eighth in the standings with much-improved C34 car. Rookie driver Felipe Nasr proves a revelation, his partnership with Marcus Ericsson garnering points at nine of the season's 19 rounds.
Endure worst season in team's history, ending a campaign pointless for the first time. Despite Sutil's and Gutierrez's best efforts, uncompetitive C33 proves hard to master and the former's 11th places in Australia and Hungary are their best results.
C32 notable at launch for unique narrow sidepod design, but initially fails to live up to expectations. Benefits significantly from mid-season tyre revisions, with Hulkenberg qualifying third and finishing fifth in Italy as team score 50 of 57 season points in last eight rounds.
Season starts well, with Perez earning high praise for impressive podiums in Malaysia and Canada. C31 proves a competent, all-round package and, though inconsistent, Perez and Kobayashi add further podiums in Italy and Japan in the second half of the season.
Strong first half of season from Kobayashi and Perez, with regular Q3 presences and top-ten finishes. Perez misses Monaco after qualifying crash, then sits out Canada where Pedro de la Rosa steps in. Difficult end to year but Perez and Kobayashi stay for 2012.
Ferrari-powered C29's pace and reliability initially disappoints. Long-term technical director Willy Rampf replaced by James Key, ex-Force India. Performance gradually improves, with regular top-ten appearances. Nick Heidfeld replaces Pedro de la Rosa for final five rounds.
Slow to adjust to new regulations. Podiums in Malaysia & Brazil are rare highlights in tough year in which they drop to sixth in standings. BMW announce they will withdraw from F1 at end of season and in November sell team back to founder Peter Sauber.
Radical F1.08 proves highly effective, powering Robert Kubica to the team's first win in Canada and turning them into genuine title contenders, with podiums at nine other races. Late-season developments less effective, but still finish third with an impressive 135 points.
From the outset occupy the 'best of the rest' slot behind Ferrari and McLaren, scoring in all 17 races, including two podiums. Heidfeld proves the dominant driver, but despite a brutal accident in Canada, Kubica also records several strong finishes.
Fifth in standings in first campaign under BMW control, despite early reliability problems. Part company with Jacques Villeneuve mid season, replacement Robert Kubica scoring Italian podium, matching team mate Nick Heidfeld's Hungarian result.
In June, Peter Sauber announces he is to step down as team principal after negotiating a takeover by BMW for 2006.
Major wind tunnel investment pays off handsomely with impressively consistent season. Score points in 12 races to finish a lonely sixth in the constructors' table. Sign former champion Jacques Villeneuve for 2005.
