In GTE-Pro, any one of those cars (except #98) could easily be a winner.
It's going to be really tight in LMP1 as well. I have a lingering feeling Audi may have the pace over the Toyotas at Silverstone, but I couldn't say for sure. The Ferraris are certainly very quick in a straight line, as well as the Aston Martins. I'm leaning towards the Aston Martins in the reliability department, but really if all cars are flawless in their pit work, staying on track, not hitting each other, etc., I really believe we could see a 1-2-3-4-5 (#97, #51, #71, #91, #92) all within 10 seconds at the end of the race. It should be a really good race... the best the WEC's seen, I think.
