Ultima GTR- officially the fastest supercar in the world

The Ultima Factory have set a catalogue of devastatingly fast world beating performance figures this week using the same 640bhp Ultima GTR which smashed the 0-100mph-0 world record of 10.3 seconds. 0-60mph in 2.7 seconds.

Ultima utilised the facilities at the world renowned Motor Industry Research Association (MIRA) and Bruntingthorpe Proving Ground to set the times. All tests have been strictly conducted, overseen and verified by an official from Datron Technology who are acknowledged by the Guinness Book of Records and the motoring press as official timekeepers.

The Ultima GTR was fully road legal, fitted with road tyres, built to a standard factory specification and it was driven to and from each test venue.

The world beating performance figures obtained are:

0-60mph
2.7secs

0-100mph
5.5secs

0-150mph
11.8secs

30-70mph
2.0secs

0-100mph-0
10.3secs

100mph-0 Braking
3.9secs

Speed Achieved
204mph on the Bruntingthorpe straight

Top Speed
231mph est. (gearing limited)

Standing ¼ mile
10.5secs @ 140mph terminal *



Engine
Chevrolet V8 377cu in

Power
641bhp

Torque
545ft/lbs

Transmission
Porsche G50


* NOTE- The standing quarter mile time would be at least two tenths of a second faster if tested at an official drag strip as it uses a timing system which is configured differently to the Microsat GPS equipment operated by Datron. Also a seasoned drag strip would provide increased traction, which would reduce times even further.

What do u mean the fastest supercar? Do you mean the fastest street legal supercar? Bc the 1994 Dauer 962 LeMans does 0-60 in 2.6 seconds and its topspeed is 250mph 😛
 
As its a kit car does it count as the fastest production motor vehicle? Or is it just the fastest road legal car?
 
Was that motor forced induction?

If not, then I don't go for it having 641 "Streetable" horsepower. No way you can get that out of a 377" engine and still run on pump gas unless it's blown.

If it's now blown, then I wouldn't really say it's a street car if you have to run racing gas.

Yeah fastest street legal car... here is the link to the site.

http://www.ultimasports.co.uk/gtr/index.html



All of the times were set by a standard, factory built, fully road legal, road tyred Ultima GTR built using all of the high spec factory specified and proven parts. The car was even equipped with heavy luxuries such as air conditioning but no traction control devices; launch control systems or ABS braking aids were used. The car was fitted with its recommended Porsche G50 5 speed transaxle and normally aspirated 640BHP 377ci Chevrolet V8 engine which is a standard offering by the factory from its official engine suppliers American Speed at www.amerspeed.com.
 
It doesn't really count as a supercar beater since it's not a production car. It's a kit car. Still, what means of induction (super or turbo?) do they have on that 377?
 
looks like it handles like cr@p, it lost control just braking from a straight line (around 80 mph maybe).

Absolutly NO refinement. Also it can do is go in a straight line, and even that is questionable.

My advice, get a early C5 corvette for around $18k, then you got yourself a high performance daily driver.
Or spend 9K on a nice turbo kit (to get to the other car's 27k) and get 600-700 rwhp easily. AND be able to destroy this GTR on the track, and be able to drive around town and not be a total joke.

getting 2HP per Cubic inch blown should not require racing gas.

the car is a street car....you can possibly fill it up at the filling station you work at. 😉

hheheh
 
It lost control braking from 100mph. They were trying to break a record not slow down nicely. Have you ever driven a car without ABS? If u just slam on the brakes that happens, but if you were at a track you would NEVER do that.

How can you judge otherwise how it performs on a track?

If your gunna get a turbo "kit" for your Corvette go with the Lingenfelter 725bhp package for 50,000. You also get a warranty. if u want a crack-addict job yes just get some turbo kit throw it on and crap your pants each time u want to push your car ;-)

You can't get 2hp per cubic inch from a small block without either high compression, or forced induction.

If you have a turbo or supercharger, you can get that HP, barely, and still run on premium.

If you are running naturally aspirated, you aren't going to get 640 hp from a 377" engine without some serious compression, a big fat roller cam, and some serious head work.
All of which would make the engine un-streetable, for all but the hardest of the hardcore.

My 427 in my race truck has 640 hp, and it has 14-1 compression, .714" lift roller cam, and better heads than most any small block config. is capable of.
That has to be a pretty radical 377" engine to make that kind of HP with no blower.
No way it's running on pump gas, unless that pump has 110+ octane.

whatever only idiots would attempt that if not locked into a racing class which would then dicate *BUY A DAILY DRIVER*.

my dad's 96 bronco built very mildly gets about 400hp (wheel power) out of 408CI no blower, 9:1 compression, mild cam, 351W small block originally. Runs 92 but can go to 89 when it's cool.

Vette took 1-2 in its class, over the Ferrari's.

so did the cobra in the past...

the GTR is not a production car though....so lemans is not offering to it.

I was just trying to make a point.

It like building a manned missile with 2 inch wings in order to break the world air speed record :/

Not very practical IMHO.

Well, now I have no doubt why domestic guys say there's no replacement for displacement.
