And now, the facts, proving you wrong. Lets start with car weight... Here you can see the matrix that the ACO uses for GT1 cars to determine their restrictor size, 1125kg is the minimum weight that the cars can run. Next, the bulletin from the ACO stating that each car had to add an additional 25kg to the minimum weight, bringing it up to 1150kg So, there you can see that no additional weight advantage was given to either car. The only other things that can determine performance are restrictor size and fuel capacity. The following were taking from the Le Mans website, which has a shit ton of data compiled from the race. As you can see, in race trim, each team elected to run their car as light as possible, as well as they both have the same size fuel cell, 90L Looking at the restrictor size, and their corresponding weight based off the chart above Aston: 2 - 30.7mm; larger than 1125kg, but smaller than 1175kg, on a 6.0L motor Corvette: 2 - 31.2mm; corresponds to a car that weighs 1225kg for a 7.0L motor Its obvious that the C6R has a motor advantage. Looking at the side by side pics, hp is nearly the same, but the C6R makes 84 more ft-lbs of torque 1200 rpm earlier. "Dude, wtf, you proved us wrong, the Astons weren't cheating!!! How did they win then??" They ran a flawless race. Unlike the Corvette who spent at least 15 minutes changing a bad alternator.
