Curb Weight: US Super Ferraris, CS and Scuderia

McLaren F1

Greg A

 

Maybe a ZR1/Z06 and Viper?

 

I second the Mac F1. No way in hell does that thing (with all fluids) weigh in anywhere near 2400 lbs like claimed.

 

I third the F1. I would love to see that plus the Vettes as previously mentioned and maybe an oddball in there for fun, idk maybe the MB SLS?

 

Maybe Cavallo will let us weigh their 917-30.

What about 997 GT2, GT3, etc, other high end Porsches? And some Lambo models for comparison to their Ferrari counterparts (it would be interesting to see how a Gallardo Superleggera stacks up against a Scuderia and Challenge Stradale)?

Good work with everything Bill, thanks for the contributions to the community.

 

or you could say the the US Scuderis is 50 lbs lighter. Bill weighed cars with a full tank of fuel. However, there can be up to 156 lbs difference in weight depending on fuel load.


The US cars don't have side airbags, they use the same bumpers, and seats.

The Yellow Scud Bill weighed doesn't have other lightweight options such as rear carbon deck lid (-22 lbs), cabon rocker panels (-9), manual windows (-42 lbs). The car still had the tools and car cover bag and battery charger (11 lbs), and there can be between 0 and 15 lbs of fluid in the windshield washer reservoir.

 

Any opportunities in the near future to get numbers on the mighty McLaren F1?

 

The F50 GT1 weight is crazy, I would have guessed under 3000lbs but 2000lbs is awesome.

 

Yeah, that is surprisingly low. Even a F40 LM weighs a little over 2400 pounds. And that is light!

 

Is the exhaust different from one F50 to the other? Seats are another "easy" place to look for the extra mass in general.

 

Bill-

Any more opportunities to weight cars over the winter?

The Mac F1, Lamborghini's, perhaps some vintage icons for comparison, like a 289/427 Cobra or Ferrari Daytona?

You're work so far is appreciated, this thread has proven very interesting.

Thanks!

 

Got a prompt to this thread

This is my Mazda RX7SP, part of my project to equal Ferrari F40 performance. I hope its worthy to post here its a one of 25 special race vehicle made for endurance racing in Australia in 1995. very successful car winning the 12hr endurance races against 911RSCS, F355, GTR, NSX, Lotus Espirit Turbo etc etc etc.

Current tested specs are
~440bhp
0-100kmh in 4.40 seconds (VBOX3i)

Here is the Kerb Weight of my RX7 SP (totally full fuel tank, all fluids, tools, spare tire etc, ready to run). My car has a 110+liter carbon fuel tank (you can see it just poking out the bottom left rear of the car) :smile:

2826Lb or ~1282kg as pictured.

(minus spare tire, tools, jack etc = 1264kg)

 

Sorry for the later response to this thread but I really feel more research is needed here as your posting about the CS weight has opened up MORE questions to me than its answered.

I am a bit confused about why your figures for the CS weight are so high compared to the sales blurb Ferrari quoted against the CS as having a DRY weight of 1180kg's (2,601 lbs). Just to add a little bit more detail to the understanding of moving from 'dry' weight to 'kerb' weight on a Challenge Stradale below I present the details of all the fluids required to drive the car (minus fuel).

Fluids Required (which are not included in 'Dry Weight' quoted by Ferrari)

11.5 litres (25.35 lb) of Engine oil
3.5 litres (7.71 lb) of Gearbox and differential oil
1.0 litres (2.20 lb) of F1 transmission oil
2.0 litres (4.40 lb) of Hydraulic steering system & steering box
1.0 litres (2.20 lb) of Air con compressor gases
18.4 litres (40.56 lb) of Engine coolant
1.5 litres (3.30 lb) of Brake fluid
7.5 litres (16.53 lb) of Window washer and xenon headlight cleaner mixture
---------
46.4 kg's (102.29 lb) total fluids with NO FUEL and NO DRIVER
---------

The fuel tanks consist of ;
95.0 litres (209.43 lb) of Fuel tanks

So its basically ~200lbs (approx 90kgs) for 1/2 tank of fuel and essential fluids.
(~100lbs for essential fluids and 1/2 tank of fuel is around the same, ~100lbs.)

Ferrari where insistent in their sales brochures that 1,180kg (2,601 lb's) was the lowest dry weight possible (a European car with full lexan side windows, no stereo, no extinguisher, etc.).

I was therefore expecting to see a minimal car be;

a.) 2,601 lbs - Basic Dry Weight car
b.) 102 lbs - Essential fluids

Total: 2,703 lbs - lightest possible cs with no fuel.
Total: 2,808 - lightest possible cs with 1/2 tank of fuel.

Where I'm confused is how did the car weighed get to the bloat of 2,949lbs with NO FUEL.

Thats a highly significant 246 lbs ( 2,949 lbs - 2,703 lbs) difference between Ferrari quoted best weight of a CS and the car that was corner weighed here.

What is even more disturbing to me is that its basically the 110kg's that Ferrari said they removed from the Modena (!) to begin with!!! So...

Q. How much of this extra weight differences be down to US Holomogation for the US market place (I know US cats and headers are a lot heavier than Euro ones for example) and even the bumpers are heavier too for improved impact absorbtion but how far does this go?

Q. Are we talking about removing virtuall ALL the weight savings over a basically equipped Euro Modena ? If so OMG...

Q. How much of this extra weigh observed is to do with options? Seems like the car was already conservatively spec'd. No stereo and no fire extinguisher or roll bar for example.

Q. Has anyone yet weighed a European spec CS? Both a LHD and RHD versions to compare the difference?

Q. Did Ferrari lie about the Dry weight of 1180kg's on a CS?

Q. Am I missing something???

 

Ok how to you drop 900 lbs. from an F50 ?

 

I've heard the seats in the US car alone are about 40 lbs more each

 

Factory exhaust on both?

 

It's the stripe.

 

I was thinking the same thing. Stock exhaust cans are heavy!

 

Start by replacing the open top tub with an enclosed tub...
