@Michael
I see your question and is really a very good question.It’s a question that i have posed for years.
My personal answer is no. We don’t know and we will never know. Not only us but most of the people that even work in formula 1 or also the driver itself doesn’t know 100% if he had the exact same technical specifications as his teammate. Even his race engineer (and believe me i’m an engineer not in cars but in another sector) doesn’t know exactly. In fact the only persons (which are few in numbers) that knows exactly are the General director, technical director, designer, some providers, executive builders and some engineers of the cars, the others persons even if they work in the same team do not know or are not allowed to know. I’m not talking about visible parts…things that the tv-s or newspaper or photos can reveal to fans,i’m talking about a full complex infrastructure that starts with drawing the car in paper and finish with seating the driver to drive. Nobody is allowed to talk not because they don’t want to talk but there are contracts that doesn’t allow you to talk and if u don’t respect them…you pay the price and remember that talking to the media is the same as giving information to your direct opponents.
Even when a driver says: “i didn’t have the same car as my teammate”. I don’t believe 100% not because he’s a liar but because maybe a driver can just find a justification why he is losing against his teammate…and give the fault to “the cars were not identical”….but maybe he’s right…maybe not…in the end of the day we simply don’t know… it’s all i’m saying. Now there are some case when is visible (silverstone 2010) and we all knows, but there are also what i call the dark components of the cars that we simply don’t know.
Remember that program and build a F1 car is secret to each team. You don’t know how they operate at least if you dont work in those two sectors (program and build) for that team…and not just a normal employer but with a highly position there.
There are only some personal opinions fans. Every fan is allowed to have opinion if one or another driver have the same spec as his team mate, but these remains personal opinions.
I’ll give you my personal opinion. I think that when a team is so dominant it’s more easy to manage the cars. I’m referring to Ferrari 2001-2004 and red bull 2010-2012. I personally believe that Barrichello first and Webber second had not and have not the same cars as their teammates. I have 1 thousand reasons (which remain personal reasons) and it will be long to explain them. I think that in the 2001-2004 maybe only the 2004 championship could have had a different winner if the cars were identical…maybe. I’m personally quite sure that in 2010-2012 If webber would have had the same car with Seb maybe we could have had a different WDC in these years.
As i say these remains personal opinions and i’m not able to prove them (as all the others personal opinions) but i believe that my opinion is right.
My message was a little bit too long but i hope you get right my opinion, and i also i think that your thread is a good one. I’m also not strong in grammatical especially in english but i hope i explained my opinion right.
