Back in August, SSC->ke1114 unveiled the Ultimate Aero XT, which was a special edition Ultimate Aero featuring an all-new 423.6-cubic-inch 1,300 horsepower engine, and an updated exterior and interior. The XT was limited to only 5 units with each carrying a different price tag, with the most expensive one being the car number No. 5 at a whopping $850,000.

According to SSC, the final Aero XT is now entering production, so if you were planning to acquire one, it looks like you have missed your chance. This last Aero XT features an exterior color specially chosen by the customer and that will never be used again on any Ultimate Aero or Tuatara.

This special edition also features some key assemblies that will be featured in the upcoming Tuatara. The company’s new supercar will be delivered to first customers in 2013.

Our hats go off to the bunch at SSC, now we just need to wait and see is the Tuatara is everything SSC has touted it as – essentially a Bugatti Veyron->ke1112 killer…
