Toyota = ex-Rally team, developed a car for 2001, spent a lot of time preparing for their debut season. Massive budgets too and had their own engine and gearbox. Not a fair comparison.
Stewart = long time F3 level team, progressed through the ranks and made it to F1 with Ford backing. Perhaps a fair comparison, but they were prepared for the season quite a bit in advance and had a fair bit of Ford backing.
Super Aguri = long time JGTC/Formula Nippon team, massive in Japan but no experience in any other series. Bought the 2002 Arrows chassis to run with intially and they had a little bit of Honda backing.
BAR = ex-Tyrrell team, though very few Tyrrell men stayed on. Almost a complete restructure from Tyrrell, Reynard-designed chassis, lots of sponsorship from BAT and 555.
Toyota scored on debut but really had a horrible season, scoring very few points and only finishing ahead of a dying Arrows team. Massive budget and preparation got them nowhere.
I do think it is harsh to compare those teams to Toyota (thats why I didn't mention them although they were my favourite team but you know what I think HSR will not finish have their races this season and USF1 as well already have a 4 straight retirment streak
as for Lotus and Virgin well time will tell but again I have never seen such bad teams in one season but I guess we will see how the season unfolds.
Stewart got a lucky podium in their first season but otherwise retired from almost from every race.
Super Aguri scored no points in their debut season and finished last in almost every race they didn't retire from.
BAR also scored no points and almost retired from every race, Villenueve had a remarkable 11 race retirement streak!
You don't think any of the 3 new teams can beat these debuts? I think Lotus have a chance to beat all 4, and Virgin and HRT merely have to finish races to beat all except Toyota, which is no bad thing considering the massive difference in budgets...
And considering the massive retirement streaks of those 4 old teams, do you still think it silly that new teams aim to just finish? You can't win races without finishing
