• SSC Ultimate Aero Twin Turbo at 255 mph

Shelby Supercars (SSC), manufacturer of the ultra high-performance Ultimate Aero Twin Turbo, set the new "World’s Fastest Production Car" record with an average top speed of 255.83 mph. And they got it all on video! That car is fast!

Confident of the 1183 hp vehicle’s abilities, SSC set out to validate their top speed claim in accordance with the strict guidelines set by Guinness World Records. Among other requirements, in order to meet Guinness’ approval, a vehicle testing for the top speed record must drive down the course, turn around, and make a second pass in the opposite direction within one hour. The vehicle’s official “top speed” is calculated by averaging the top speeds of each pass in order to negate any favorable road or weather conditions.

The Ultimate Aero posted a top speed of 257.11 mph (413.83 kph) on its first pass and 254.55 mph (409.71 kph) on its return pass, yielding a new top speed record: a staggering 255.83 mph (411.76 kph). The data, collected by Dewetron’s world-renowned GPS tracking system, will be verified by Guinness before the Ultimate Aero is officially crowned the "World’s Fastest Production Car." This breaks the current official record held by the Koenigsegg CCR at 242 mph by 11.83 mph and the Bugatti Veyron’s unofficial speed of 253 mph by 3.11 mph.

I think the Atom does 2.89, (2.7 official). Thats still slower than the Veyron. Don’t know about the X Bow. I’ve never even heard of it.

The Atom can hardly be described as a car...

but what about the ariel atom and x bow... i thought those cars were goin into production.

nah, they got the top speed nailed but the Veyron still holds the acceleration times for production cars.

There are tuned cars that can do sub2’s though.

you avg the top speed to eliminate any favorable conditions that may help the car go faster... such as the wind blowing towards the back end of the car and such. you run the car in opposite directions to get a clear cut test with no advantages...

well i was talking about the top speed is this case... but even still there are faster acceleration cars than the veyron...not many but a few i didnt know it was official but i also heard that the Ultimate aero scc got up to 257 officially just recently

uh, jtm, the Veyrons speed is official. It doesn’t say so on this site, not on this page anyway, it is true. That is one of the reasons the Veyron was hyped.

What I want to know is, when you say Worlds fastest car, aren’t you actually implying that that about the acceleration rather than top speed?

And doesn’t this thing have a speedometer? Why the averaging top speed?

you’re freakin retarded... the veyrons top speed record is unofficial... which means they only went in one direction probably with the wind at their back...it may not accelerate as fast but it has an official record as the highest top speed. unofficial records dont mean .

i could say i got my 240sx to go 464687343546549mph but unless its official its just a load of bull .

this is sooo slow dred only 2.78 secs to go from 0-60?!! an they say this is better than a the veyron plz bugatti does it in jus 2.3!! an it is still the best of the best

the veyron also did 255 so it ain no big deal an even if it has a higher top speed it still doesn’t accelerate faster than the veyron so it still isn’t better
