This isn't a knock on Chevy, or a knock against anyone here, but here is my take on this. After thinking about this for a bit after the mess in the other thread, my guess is that they are talking about "American Racing" series. Because, lets be honest, 99% of all American motorsports fans don't give a crap about F1, WRC, JGTC, DTM, PSC, or BTCC, or anything like that. Those series just don't exist to them. Here in the States, its all 85% NASCAR, 10% NHRA, and the other 5% to ALMS, CART, INDY and others.
In all of those American based motorsports, I would think Chevy has a very good chance of having the most wins. Like was said before, they have over 500 wins JUST in NASCAR. Take the other few series that they race in, and have raced in, and they do have a good chance of being tops. So, they do what you would expect any company to do. You talk about what people know, and leave out what they don't. Most in the entire world of motorsports all time??? Probably not, but who knows for sure. But, most in all American based race series all time???? Very likely.
Another thing that makes me think this is Chevy's own website. If you look at their "Motorsports" section of their website, they only list 5 race series. They list NASCAR, Craftsman TRUCKS, INDY, ALMS, and NHRA. And, they aren't even in INDY anymore. Like I said, in those big American series, and any other big ones from the past here in the states, I have no doubts that they probably have the most wins.
It makes sense really. Most, not all, but most, people who buy Chevy cars don't give a crap about those other series I mentioned. Its just like every year when the "Highest Paid Athlete" topic comes around. I bet 9 of 10 Americans say Tiger Woods. And, to them, in America, thats right. But, in the WORLD of sports figures, its Michael Schumacher. They don't know who the hell that is, so to them, its Tiger. So, most wins in motorsports to an American audience??? Theres no chance they think its Honda, Ferrari, Lotus, or Porsche. Its the bowtie in the states, so its the bowtie in their mind.
