McLaren Auto Porn

Serious Wheels posted some high rez pics of the 2011 McLaren MP4-12C GT3 car.  It's a beautiful car but the horsepower numbers seem low.  The page claims it's a 3.8 liter V8 with twin turbo chargers and it's putting out 493hp.  That seems a little wack.  My stock Mustang has a 4.6 liter V8 naturally aspirated and is putting out 300hp.  So I'm a little confused.  Click the link to see for yourself.  Serious Wheels
