Number 1 for Ultima
Discussion
Sorry for the DM link, but any press is good press!

Until Bugatti reveals its hand, Ultima claims the record for the fastest-accelerating road-going car in the world.
The 6.8-litre supercharged V8 strapped to the Evolution Coupe produces 1020bhp for skin-warping performance and a ferocious 0-60mph time of just 2.3 seconds.
Just because it currently has the crown as the quickest car to clip the national speed limit doesn't mean it's unfathomably expensive. In fact, you could have 19 of the British-built sports cars for the price of one Chiron.

Sorry but I can't see how a 2wd car can get that time down for 0-60. Even with much lower power , cars struggle and have to use fancy traction control to get decent launches.
I mean dragsters do... With that power and drag slicks on, its more than possible for this car? (Not a fair test if the other cars in the article are using road legal, but I'd have thought that time, with the 'best' tyres is achievable)?4WD doesn't help much after a certain point, once nearly all the weight is transferred to the rear wheels under such extreme acceleration, having "traction" on the front wheels would just add weight to the car and the center differential is loosing a lot of efficiency by transferring the power to the rear wheels. All this is reducing the efficiency, the power/weight ration, thus the acceleration.
First of all, what the hell good is 0 to 60 unless your in a bar or at a drag strip. Meaningless number on a race track or on the street. But what it really says is whats the 25 -30 mph to 100 -120 thats where this car lives and thats where any Ultima with 500 or more HP KICKS BUTT. At 30 MPH your out of 1st gear, 100 mph is only one shift away. Let them have their PDK MAGNO TECHNO whatever. 4 wheel drive just makes up for cars that are to heavy to accelerate all that mass on two contact patches. Carbon brakes same thing just to much mass to decel so you go to carbon brakes that really arent that neat until you get them hot. Colin Chapman was right less mass is where its at, he just never had enough power available in his street cars to really exploit it. just me on a rant, lee

+1 I still can't find another car (of this type) to fill a space in my garage. ROWDYRENAULT said:

+2I am almost certain the 0-60 time is done in 2nd gear by factory. Reduces wheel spin and no gear change.

Dragsters have a rear axle that uses 'torque effect' to push the tyres onto the road. You can see this if you watch a drag car that is set up wrong hop on the back wheels as it launches.The Ultima has limited opportunity in the rear wishbones for this geometry as they are not trailing arms.
Drag axles don't hold a steady line as you power out of a corner.
Paul completely agree with your second gear start for 0-60. I had my g50 moded by CMS with a longer 4th and 5th gear and that works well for freeway use. But if I ever get the opportunity, meaning I break the box big time, I would start with a first gear 3/4 of the way to second and then spread out the other 4 gears to the same 5th gear ratio I have now which is a .66 overdrive. lee
If these were verified times they would be video and "official" statements as opposed to claims.
Not saying the claims are spurious but another trip to Dunsfold to prove this car is quicker around the track than the previous 720 would be a good start. not to mention fantastic publicity.
Roll on some official timing events and the Nurnburgring!!
Trouble is I suspect the order book is overflowing so no real need to prove anything.

If you haven't seen the Engineering Explained channel on YouTube it's worth so time if you're the curious type. He covers the theoretical limit to the fastest 0-60 time with a couple flaws but still pretty close.

' cough ' "bullst" ...
No disrespect but why do the records and claims for performance never get backed up at public events with crowds/independent verification?
We've had years of the "top gear test trak" debate is this the new one?
Will customer cars achieve these figures and if so can we see proof at some point?
Fair play if so!

try you car
i won 3 british championships drag racing, so know how to get the times of 0-60-0-100 and 1/8 & 1/4 mile times to the minimum on a motorbike, but never really competeted with a car
This is a program that been developed to use the maths to work out times, but sadly doesnt allow torque into the equation.
the formular is close and i did beat it a few times, but overall it was about right.
Traction is the enemy and with grip juice and Avon Park(santa pod uphill so loose 0.3 seconds on the 1/4)best times could be achieved by its upto the factory to show the records and be in teh guinessbook of records to be official.
