What happens when you get millions of dollars worth of cars to the Top Gear test track for an ultimate drag race - but then the heavens open!!?

Unfortunately, the weather wasn#039;t exactly on our side, but the heavy rain made for a unique opportunity to see just how these cars fared when conditions are less than perfect.
