My question is if the toyota cars were so bad why is it that they were on podiums pretty often last year?
They had five podiums in seventeen races. Given that there are three steps on the podium, that means there were fifty-one podium places on offer, that meant they were on the podium 9.8% of the time. So I don't know what you mean by "pretty often". For comparison's sake, there was a Brawn driver on the podium 45.1% of the time.
That, I think, is much more worthy of the description of being on the podium "pretty often". Toyota went nine straight races (Spain to Monza) without getting anywhere near the podium; the closest they came was fourth in Turkey.
Toyota was never a bad team. You can't just jump into F1 and be competitive, no matter who you are. Other teams have bought teams. Red Bull used to be Jaguar. Mercedes used to be Brawn who used to be Honda who used to be BAR. Toyota came into F1 on it's own. Built everything from scratch and hired who they could. The toyota way was in place but the management was different. It wasn't what F1 was used to and that caused problems. But Toyota was never a bad team.
How were they not a bad team? They certainly weren't in league with the likes of Minardi and the tail-enders, but in one hundred and forty race starts, they only got on the podium thirteen times. They claimed just three pole positions, three fastest laps and no wins. They were in the habit of employing mediocre drivers (Schumacher, da Matta, Panis, Trulli), and their most successful driver -Glock - had a success rate of scoring 1.5 points per race. Toyota may not have been a bad team, but they sure as hell weren't a good one.
Gascoyne came in and the team did good. Trulli was never a race winner, he won once at Monaco, the slowest track. He was always good at qualifying but in races he was called the Trulli train. He couldn't win in a car that Alonso could win in. In his one win in Monaco, he qualified on pole. Most of the races in Monaco are won from pole. Every other race hes qualified on pole, he has never won. Glock was never a good qualifier. He was sacked from F1 before and went back to GP2, then came back to F1 with Toyota and never matched Trulli in qualifying. Before Glock, Ralf Shumacher was washed up as well. He couldn't match Trulli in qualifying either. No one even offered Ralf a contract after his stint in BMW Williams. Neither one of those drivers were 'A grade' the way Alonso Hamilton or Raikkonen are. If they had one of those guys they could have won. But Toyota was fine settling with a Glock and a Trulli, who they could pay less and expect less as well. I'm not sure why anyone would think either of these guys are top drivers. If they were they'd be at top teams. Glock needed to work on his qualifying pace and Trulli needed to work on his race pace. We see where they're driving at now.
So if anything Toyota flattered them, it wasn't them who flattered Toyota.
I'm still failing how any of that proves your argument that Toyota were a "good team". If anything, you're arguing for them being a dismal failure.
There are 3 teams that have or had interest in Toyota's car. Stefan, HRT and Durango. I don't think there is a rule that states you can't build a new chassis for the season. If that were the case Mercedes would be illegal, as they built an entirely new chassis. If they can do it I don't see why HRT can't 'purchase' the designs of the TF110 and use it to make their own car. Also, to those saying that most of the Toyota crew is gone, that doesn't mean there are no Toyota employees. Pascal Vasselon is still employed by Toyota and he's the head designer of the TF108 TF109 and TF110.
Mercedes did not build an entirely new chassis. What they did was increase the wheelbase by moving the front wheels forward in order to get a better weight distribution.
Hispania cannot purchase and run the TF110 because they have homogated their chassis. Homologation is a process of standardising parts. In this case, the driver's survival cell. They submit the designs to the FIA, the FIA approves them, and after that, it is set in stone. They are not permitted to make any changes to the survival cell - they
must use it all season long. The only exception is on the grounds of safety, which requires them to apply to the FIA for a special dispensation. Because the TF110's survival cell is different to the Hispania F110's, Hispania cannot run the TF110 this year. Nor can they take the TF110 parts and swap them for the F110's so that it's a TF110 with an F110's survival cell. These cars are designed as a whole, and it's likely a chop-job would just produce a worse car because they're compeltely different shapes. You could make the argument that they could employ the designers of the TF110 to synthesise the two together, but Hispania do not have detailed-enough schematics of their current car. I've heard that they won't be able to introduce upgrades until they finish reverse-engineering it, which will not be done untl Valencia at the earliest. Given that it would take months to design a hybrid TF110/F110 chassis, it would just be a waste of time, effort and money.
