It costs $1.3 million to buy one, but each one costs $2 million to build.
There's a faster production car available now (The SSC Ultimate Aero TT), but it's not quite 3 MPH faster at the top end and slower 0-60 because it's rear-wheel drive.
At top speed the tires would disintegrate within 15 minutes, but it would use up its 22 gallons of fuel in 12.
Remember when putting a Holley 900 CFM carb on a muscle car sounded like a lot? This thing sucks in 10,000 CFM at full throttle.
