Aston Martin wants to assure you the same V12 powers not only the V12 Vantage, but also its LMP1 race car. So it brought both of them out on a typically rainy afternoon. They can't all be sunny days, right?
In addition to the to-line Vantage and the 2010 DBR1-2 Le Mans race car, that V12, of course, also powers the One-77, DBS, DB9 and the Rapide.
The DBR1-2 competed throughout 2009 and 2010, winning the Le Mans Series in 2009 and landing on the podium three times in 2010. Actually, the car didn't actually land on the podium, that would be a devastating accident and not conducing to finishing first, second or third.
