Curb Weight: US Super Ferraris, CS and Scuderia

fwiw I took the top off but it wasn't very heavy.

 

Cool car Bill! I heard you mention to Roger in Santa Barbara a few weeks ago that you had bought one. That is a hairy chested machine from an era before airbags, traction control and decent seat belts. See you next time you are in SB!

just found this thread. what a great idea.
it would be useful to have the real hp alongside as well, but the variations on that might be so wide that it wouldnt be conclusive.

btw, when my f40 was at bob houghton's they measured the weight at around 1180 kilos with all liquids - no idea what level of fullness the gas tank was though.
and their guess on the bhp was 550+. it certainly feels fast !

also my euro cs supposedly weighs 1270 kilos. not sure what the level of gas in tank is for that though.

 

Bill,

The Cobra is to die for, what a beauty, congratulations.

No 458 Italia yet on the scales?

 

My car I think was weighed at the factory at 1145 kg. It was written on the invoice, but when I weighed the car during the Italian revision the figure was incredibly of 1060 kg with fuel reserve. This weight made ​​me wince, but I doubt it was real. It would be too low..

Would be interesting to know also both engine curves. Power and torque curves, because these F40 engines could hide several characteristics. There may be differences of 20 hp in top of the power, as same power but different torque, as not compatible curves. Since we talked I heard more opinions, also hearing Ferrari (factory and servicing) people saying there were around 15/20 hp when catalysts were employed. Also engine built accurancy process was important. But also engine running in and engine conditions are basic in these kind of results. When Ferrari tested their F40's engines at 470-490 hp at that time, the results were coming from new engines and could been lower of 20-30 hp than a good running in engine can do later. Then if we add the influence of the torque, it is easy to imagine the variability of results that may come out when we are at the wheel.
Today, from over 20 years, we may be facing of cars fitted with high conserved brand new engines, still tangled engines, as very good running engines, as tired ones desiring servicing. So the gap in engine ability variable may be greater. Some cars are today fitted with Tubi exhaust. Some cars spend their lives in states that fuels are more suitable than others...octane rating are very important too. Behind all this is very difficult to standardize the 60-130 performance of a old turbocharged car expecially taking more than one of these variables.

 

Tested curb weight of euro-spec cars with full fuel tank:
1300 kg = 2866 lb -- GTO (1984)
1240 kg = 2734 lb -- F40 (non-cat, no active suspension, slide plastic windows)
1254 kg = 2765 lb -- F40 (non-cat, no active suspension, 'Lusso' glass windows)
1381 kg = 3045 lb -- F50
1462 kg = 3223 lb -- Enzo

 

Tested curb weight of euro-spec cars with full fuel tank:
1281 kg = 2824 lb -- 328 GTB (non-cat)
1480 kg = 3263 lb -- 348 tb
1417 kg = 3124 lb -- 348 tb Challenge (road legal)
1440 kg = 3175 lb -- 348 GTB
<1400 kg = 3086 lb -- 348 GT Competizione (road version)
1444 kg = 3183 lb -- F355 Berlinetta (1995, w/o airbags)
1427 kg = 3146 lb -- 360 Modena F1
1365 kg = 3009 lb -- Challenge Stradale (with cage)
1471 kg = 3243 lb -- F430 F1
1390 kg = 3064 lb -- 430 Scuderia
1505 kg = 3318 lb -- 458 Italia (2011, light spec. 2009/10 cars ~28 kg heavier)

 

Tested curb weight of euro-spec cars with full fuel tank:
1630 kg = 3593 lb -- Testarossa (1st series, non-cat. Last series including cat ~70 kg heavier)
1644 kg = 3624 lb -- 512 TR
1631 kg = 3595 lb -- F512 M
1724 kg = 3801 lb -- 550 Maranello
1730 kg = 3814 lb -- 575M Maranello F1
1733 kg = 3821 lb -- 599 GTB Fiorano F1
1626 kg = 3585 lb -- 599 GTO

 

This is a FANTASTIC thread.
Well done Bill for putting all this together.

When owners are doing this kind of thing - everyone benefits. The manufacturers will think twice about making exaggerated claims of light weight, extra hp, or performance figures which actually never materialise.

Great thread.

 

Great thread, love the Cobra. Maybe yours could do with setting up if it's not inducing confidence?

 

Bill, thanks a lot for the work on the 458 Italia, nice information on the weight distribution as well.

Based on the weight of that U.S. 458 Italia, it surely has the standard seats and not the Scuderia/16M Carbon seats (can't see the seats from pictures).

The wheels in that 458 Italia are the optional forged 20" wheels, they are 12 lbs lighter than the standard wheels. So, the same car with a full tank of fuel and the standard wheels would hit the scales at 3,497 lbs.

I hope Ferrari works hard on dropping weight from the 458, because the McLaren MP4-12C optioned right is just 50 lbs heavier than the 430 Scuderia, while the standard 458 Italia is almost 400 lbs heavier than a 430 Scuderia.

 

Why? What set up do you have?

 

Great stuff, but continues to reinforce my opinion that Ferrari has lost its way. For the 458 to be that heavy relative to the 430/Scuderia is awful. Any new mid-engine car from Ferrari should be <3,000lbs, which is why I will likely keep my Scud for some time, light, engaging, soulful ... my two cents.....

 

Wow that's heavy. 1590kg fully fuelled and standard, that used to be V12 GT territory.
I can't see how they Scud version of the 458 can be much more than 100kg lighter. At 1490kg it would be 140kg heavier than the lightest 430 Scuderia specification.

 

I'm not sure if anyone has caught this yet but their conversions are wrong for those figures. They say 313km/h which is actually about 194.5mph. I knew it was wrong from a quick glance since I have 300km/h memorized as 186mp/h.

 

What is the difference between 2011 and 09/10 cars which makes up the 28kg??

 

So between a light spec 458 italia (2011) and heavy US Spec italia the weight difference is 85 kg (187 lbs) which is too much of a variation IMO.

 

You can make that much weight difference just by the options you choose on your car.

 

How much weight do the seats save? car and driver weighed the 458 assuming full fuel at 3325 lb http://media.caranddriver.com/files/2011-ferrari-458-italia-vs-2011-mclaren-mp4-12c-2011-porsche-911-gt2-rs-comparison-test-car-and-driver2011-ferrari-458-italia-vs-2012-mclaren-mp4-12c-2011-porsche-911-gt2-rs.pdf
