I don't care for Robby Gordon, but he's right. A lighter drive has an advantage.

How big of an advantage can it be? In horse racing, it is a big advantage, therefore the jockeys are all elves. If it was such a big deal in IRL, wouldn't the racers over time all become little elves too? Clearly the individual teams think that it is not a very important factor.

"I don't care for Robby Gordon, but he's right. A lighter driver has an advantage."

"How big of an advantage can it be?"

Over 500 miles...

If the winner averaged 220 mph and the 2nd place car averaged 219.99, the 2nd place car would be 120 feet behind.

A car going 220 mph covers 323 feet per second.

So .01 mph makes a difference.
