Not unless that Toyota was 2010's Brawn
.
Toro Rosso did a good job developing their own car in 2008 didn't they? A couple of near podiums and that Monza win wasn't bad for what was formerly Minardi who got gifted a same-year Red Bull chassis (with a Ferrari engine bolted on?).
I'm not too clear on how they handled Toro Rosso's case that year though. Can someone please clarify how their car was developed in 2008 (i.e. - did they just use Red Bull's upgrades; did they develop their own alongside Red Bull or was it just all them and no technical support allowed from the A-team?).
