The title of World’s Fastest Production Car has been handed off to a new king. Behold the Shelby Supercars Ultimate Aeron Twin Turbo:

As stated on Shelby’s website, the Ultimate Aeron successfully passed the Guiness Book of World Record’s stringent test on September 13. In the test, the car must drive down a stretch of road, turn around, and then drive back up the same stretch of road within 1 hour. The two top speeds are then averaged together. This is to eliminate any favorable or unfavorable road and weather conditions that might be found in one of the directions. The Ultimate Aeron managed 255.83 mph, beating out the current record holder, the Koenigsegg CCR, at 242 mph.

Dry weight is a light-for-this-type-of-car 2750 lbs. This is good, as light cars do everything better. Power is a mind-numbing 1183 horsepower from a twin turbocharged 6.3 liter V8.

For those of you who haven’t been all that fast in a car, let the record show that 255 mph is fast. REALLY REALLY fast. Granted, it probably takes 10 miles to reach that speed, but that is almost twice as fast as my Miata will go.

Price is as out to lunch as its top speed: $550,000. Thats cheaper than a jet, almost as fast, and definitely a lot more fun. Quite the bargain.
