Acceleration: F40, F50, Enzo, CGT & Veyron

Bill I think you have right. I 've read all the 3 articles again. I remember the EU car was mentioned. Infact it was written in the R&T road-test, for its lightness, but NO for its really type version.
250 lb lighter is eaxactly the weight of EU no-cats car, it was mentioned the previous tested EU car in the article too, and here the mistaken.

 

OK I will agree to split hairs.

 

Sure. I think the EURO-spec F40 non-cat version is able a really mid 11's.

You can see it how is fast in the Fast Lane figures.
On rolling start it can match with the Enzo's figures from 30 mph to well over hundred miles per hours. But more.
0-170 mph in 22.3 seconds, with 30 mph in 2.3 secs is awesome for a 1987 car. With 500 hp only, compare to the moderns.

That's why the F40 is still an ICON.

 

Yes Eu F40s have exceeded 200 mph and I'm sure someone here will post that data.

I don't think an F40 will "fly" entering a turn any more than an Enzo would, especially judging by the number of high-speed Enzo incidents on record.

 

Italian magazine Quattroruote tested the F40 in 1989. Max speed was 323,5 kmh (201 mph).

 

More then a few have tested over 200 mph. Quattoroute hit 202.5 mph in one test and 201 mph in another.

The LM, with lots of downforce, and a nice boost in power has hit 229 mph at Nardo.

 

F40's do have some downforce factored in from what I remember reading....plus that huge wing. If a owner wants more downforce a LM wing insert can easily be added.


As for the USA cars, I'm sure under the right conditions even they would top 200.
The one test I recall hit 196 and it was a humid, windy day....

 

Quattroruote: 326.1 kph or 202.6 mph
Auto: 325.1 kph or 202.0 mph
Essai Auto: 326.3 kph or 202.8 mph
Auto Motor und Sport: 321 kph or 199.5 mph

Downforce declarations from Essai Auto @ 200 kph (124 mph):

Front: 50 kgs Cz -0,04
Rear: 120 kgs Cz -0,15

Cx: 0,34
SCx: 0,63
S: 1,85 mq

The LM is able of over 800 Kgs @ 300 kph.
The GTE has a wing more capable, so even more dowforce.
Remember that a LM or GTE are 1000-1080 Kgs car, dry weight.




PS.
Essai Auto explain that the USA F40 lost 13 HP for US the emissions omologation.

 

I've EDIT: Front is 50 KGs

I don't know about 300 kph.

Consider that a LM weight about 300 Kgs less than the Enzo...
The GTE had a downforce like a modern Fia GT figures...or little less.
It was the aerodinamic development for the 1996 BPR championship.

 

Best top speed I have read, nice to know. I added all this info to my database.

Thanks.

 

Does have that flip up spoiler....
And the LM wing is adjustable don't forget.

 

If one hit 196 on a windy, humid day I'm sure it could hit 200. Might not hit the 202.8 of a Euro car though....

 

Bill:

I have heard this stated before in stating the "Enzo is the best" case, but its worth noting that the Enzo achieves 775 kgs @ 300 kph because it NEEDS that given its speed capabilities*. As we know from the weight thread, big numbers are not always best, and its all relevant to a particular car and its needs.

Also the fact that the Enzo has no wing is just a design difference, and the down-force is simply generated in a different way using surfaces elsewhere around the car.

*In the real world there are some documented cases of Enzos taking off and becoming airborne at speeds far less than v max, and although this was caused by a gently undulating surface in the 2 cases I'm aware of, it was in a straight line - quite noteworthy I think.

 

I think Essai Auto have put out erroneous info, simply following popular convention that the USA cars have less hp (often this is true, but not with the F40).

Just because "data" is out there doesn't mean it is correct.

The USA F40 has MORE hp that the ROW cars on account of the adjustment required to meet EPA emissions requirements. 515 hp is often quoted and several sources including Road & Track have so stated.
I have spoken to 2 seperate parties involved in the actual homologation process of the USA F40 and they state this same number. We ought to get one dynoed.

 

Completely understand. But when you exclaim that the Enzo generates all this down-force, and even without a wing (!), clearly this is a personal matter for you as an Enzo owner, so, in a dispassionate manner I was simply pointing out that it generates all the down-force it does because it HAS to, given among other things its speed capability and its overall higher weight. Once it gets rolling to the speeds it can it must be generating a higher momentum than a lighter car, and I'm certain the engineers figured it needed the down-force it was set up with. The F40 clearly does not NEED that much down-force. These material differences are what needs to be considered when comparing these cars, even from a technical or engineering standpoint as you are.

 

Id say a USA F40 can do 198.
