And the award for Top Speed Achieved by a Production Automobile goes to: Shelby Supercars' Ultimate Aero Twin Turbo. Claiming a stretch of public road in Washington State for the effort, the SSC UATT made two runs in accordance with Guinness Book of World Record rules, one in each direction. The first run clocked 257.11 MPH, the second, return one came in at 254.55 MPH. The average: 255.83 MPH. That bests all challengers -- yes, even the Veyron -- by at least 3 MPH.

For comparison, the SSC's V8 packs 1,183 BHP and 1,094 ft-lbs. as opposed to the Veyron's 16 cylinders, 1,001 HP, and 922 ft-lb. In addition to a bigger punch, the SSC also carries less weight: 2,700 pounds versus the Veyron's 4,162. Much of the Veyron poundage no doubt is attributable to its interior, which is a splendid place to be even when you're not doing 250+. SSC still needs to submit the paperwork and get official certification from Guinness before it's run is, as we say, officially official. Intriguing, though, that of all the names mentioned, the one not broached was the previous holder of the top speed record: the Callaway Sledgehammer.

      I think its cute how everyone seems to be forgetting that the Veyron has never made an official top speed run, and was never officially the worlds fastest car.

      The Veyron was designed as an engineering experiment and showcase, not as a top speed contender.

      the record for fastest street legal gets toasted again this year... there are 3 other waiting for their Nardo run...and the first already reached 248mph in pretesting runs under bad weather conditions.. that the Veyron record gets beaten was only a question of time

      With the power to weight ratio so much better than Veyron, I would have thought it would better by more. I guess the drag must be a little bit more or they were just going for the record and it has a little more on tap.
        • 7 Years Ago
        The SSC website actually claims 272 at redline in 6th. They don't go out of their way to say the car can actually do that, but it's a subtle mention in the spec sheet.
        • 7 Years Ago
        Power to weight only applies to acceleration, and has no affect on top speed. Top speed is power versus aero drag.
          • 7 Years Ago
          Really...than what your saying is that even if the Veyron was 9000 lbs., but the same coefficient of drag (air), it would still have the same top speed. You might want to rethink that and add other other things to your equation.

      It also wins the world record for "worst copy-cat of the Lamborghini Diablo."

      The Bugatti Veyron can do 260mph and I really hope Bugatti are ready to take back the crown. SSC Aero? Come on! It is the ugliest thing in "production" today by far. It looks like a Diablo-McLaren design copy. Go Veyron, Go!

      Some of you guys need to take some classes or at least study up on Aerodynamics. Weight has little effect at that speed. In fact, more weight might even be helping.
        • 7 Years Ago
        Weight CAN help. At very high speeds with very high drag, traction can become a major issue. More weight is more traction.

      I wonder when we'll reach a limit to max speed in a production car

      Bugatti should just make a stripped down, barebones "racing version" of the Veyron to shut these guys up. Honestly I would be embarassed to have built one of these Ultimate Aeros knowing that it only got about 3mph faster when
      A. Its not really a production car in the same way as the Veyron
      B.It is 1500lbs lighter.
      C. It looks like every other racing car out there (i.e. its a Maclaren ripoff)

      Why did they bother? 3mph faster? They should at lest try to get 10-20mph faster before submitting this.
        • 7 Years Ago
        You are an idiot apparently. If you had read the article you would notice that the driver said they had plenty of room to improve on the top speed but there was not enough straight pavement. To get that top speed he had to drive 210MPH through an S curve, sounds really easy for you right? Oh and I guess you forgot that the Bugatti top speed of 253MPH is unofficial too? They can go ahead and make a stripped down version but "these guys" aren't gonna shut up cause they know what they are doing.

        I think it is great that a small company is taking on a international behemoth. Veyron is like the space shuttle...it burns up its tires and consume all of its fuel in 15 minutes...but it gets you to that speed. I think many people considers a sports car to be more than just speed alone, but this is a luxury car that can get you very fast very quickly for a very brief period. It isn't meant to be a sports car.
        • 7 Years Ago
        It wouldn't matter if they took out everything except the drivers seat and driving controls, as others have mentioned, weight has no influence on top speed. It's all about aerodynamic drag(which increases with the square of speed). The engine will have the same amount of drag to overcome unless they change the body/aerodynamic design.

        Now, lower weight WOULD make it handle better, and accelerate faster, which would be nice.

        I may be an idiot but you are apparently a juvenile or an adult with a very low IQ. Why call me names over something as mundane as a car blog? Grow up and get off the internet every now and then so you can learn how to socially interact with society.
      • 7 Years Ago
      Wow. They actually did it. On a public road, no less.

      I guess congradulations are in order.

        i totally agree. can you imagine the speeding ticket?
      • 7 Years Ago
      I drove that very same road a little over a week ago. A bit slower though.

      Great road for high speed runs. Very empty. You only have to worry about the Hanford Nukes.
