Q. Has anyone taken their Strad to be weighed and corner weighted? The weights from the Ferrari glossy brochure has the 360 Challenge Stradale at a miniscule 1,180kg's (2,601 lbs). Dig a little deeper and you discover this was the dry weight so that figure excludes all fluids such as essential engine oils and fuels (and ofcourse the passenger!). The Kerb Weight typically assumes to add approx 100kg's or more to a vehicle but it could be higher in real life especially if the passenger is heavier than 68kg's. Kerb weight includes adding; * Gasolene (assumed to be a 90% full tank for purposes of Kerb Weight) * Engine/Gearbox Oil (approx 10 litres) * Engine Coolant * Hydraulic Brake Fluid * Window Washer Fluid * Power Steering fluid * Drivers Weight of 75kg's (assumed to be 68kg's + 7kg's of luggage) Then on top of that the Officially Ferrari's sales blurb indicated 110kg's weight loss over the Modena but that was for the extreme version which was never offered in the US. For the full 110kg's (242.5 lbs) loss in Europe you needed to specify the extreme options (non cost options) which added plexi-glass windows and removed the stereo. In Europe this comprised of; * Deleted Electric window motors and lifter mechanism (2 of) * Deleted Lexan plastic side windows replacing Glass (55% less weight for windows) * Deleted Door window adjustment/runner bars * Deleted Electric window wiring loom * Deleted Becker Stereo * Deleted Dashboard Stereo Box * Deleted Center Dual Speaker Box * Deleted Speakers * Deleted Stereo Wiring Loom It also excluded the weight of optional extra's such as; * Specifying leather instead of cloth (adds more weight) * Optional Rollover bar * Optional Racing Harnesses * Optional Fire Extinguisher * Optional Luggage or Spare Wheel (rare options) * etc. Also the US cars had much tougher emissions and crash protection regulations than most of Europe so this adds pre-cat's and heavier impact protection bars in the bumpers. Q. Anyone know what the US Strads (on the road) really ON THE ROAD weight? I'm assuming ; * 1180kg dry weight + 100kg fluids and driver = 1280kg ~ kerb weight * 1280kg kerb weight + 30kg (assuming typical strad with regular windows and a stereo) = 1,310kg (2,888 lbs) * + any other emissions control equipment and bumper safety stuff (+20 to 40kg?) = 1,350kg? Q. Also has anyone corner weighted their vehicle? What are the weights on each wheel? How even are where front to back, left to right? Did you adjust the corner weighting to account for YOUR actual weight (versus a static deadweight?) for improved handling?
I officially weighed my lightened 996 TT with a full tank of fuel and it came in with 1475 KG, my mildly weight reduced non 4WD (of course) CS with Odessy PC 925 Battery, hyperflow cats and no tool kit, feels massively lighter to drive, at least 200 KG without being scientific
Thank you very much! No we are getting somewhere, so 3053 lb (which is 1385 kg for Europeans ) is the US Spec Stradale kerb weight without Radio. Was this weight with a driver? Full tank of fuel? Any more information on options fitted? Do you know if they had any other extras fitted such as battery tender wiring, fire extinguisher, road legal roll bar (was that an option in US?), etc? Regards, Trevor
Marc, verified by whom? Ferrari claimed 1180kg for a dry weight Euro spec lightest possible car. We know that we need to add 100kg's to go from Dry weight (as factory specified) to derive Kerb Weight from factory Dry weight it would be 1180+100 = 1280. This therefore sounds like what you read was an educated guess based on the fact the brochure said it was 1180 dry weight. However this is for the Lightest variant of the euro spec CS, the one with plexi-glass side windows, no fire extinguisher, no stereo, etc. I'm intruigued to know the real facts for a US spec car with a stereo (with regular glass windows). IMHO no way would that be 1285kg, has to be over 1300kg, likely to be somewhere around 1310kg to 1350kg depending on the drivers weight. (Normally assumed to be 68kgs + 7kgs luggage).
Several posts appeared in the past trying to compare weight of US 360 modena, spider, CS, vs. Euro versions. A search will find these posts. If my memory serves me corrctly; -- there seemed to be a concensus that the 1280Kg or 2820lb CS applies to a euro version w/o fuel, and certainly w/o a driver, not to a NA version -- a North American version was likely around 3050lbs, maybe more At the end of the day, the confusion, frustration, even torturous process of trying to esablish that a North American CS was anywhere near 2820lbs seemed futile. At best, people could take comfort in (i) a strong likelihood that if a North American version 360 modena and 360 spider was about 200lbs more than the euro equivalent, then the CS would likely be 200lbs more than the euro version, and (ii) RELATIVE to a NA version 360 modena and spider, the CS would be a couple of hundred pounds lighter, and therefore faster. But extrapolating (ii), an implication would be that a euro version 360 modena might be equally as fast as a North American CS. Your desire to have someone report an actual weighed CS with a full tank of fuel is right on the mark. No one seems to have done that, though there's lots of verbal diahrrea about what the weight could/should be. Moreover, its a SHAM that Ferrari never did help us owners clear up this issue. After all, we shelled out big $$ for a car that purportedly weighed less than its bloodline, yet could never really get clear information about the real nature of the weight savings. The weight of the CS is KEY because it has only a small HP gain over the 360 modena (25HP) and NO gain in torque. EXACTLY the same kind of confusion regarding WEIGHT is coming with respect to the supposedly lighter 430 Scuderia in North America. Anyway, if you find out anything concrete, please do keep this thread running.
Thanks Paul, good contribution to the thread. Ok, here's some more findings I got by studying the 360CS workshop manuals for the fluid weights; After some research on the dry weight fluids required to calculate a 'kerb weight' for the CS I now present some of my findings. This is not good news for people expecting a lightweight car... Metric Conversions ------------------ 1 kilogram = 2.20462262 pounds 1 litre = 1 kilogram Fluids Required (which are not included in Dry Weight quote) ------------------------------------------------------------ 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 95.0 litres (209.43 lb) of Fuel tank 20.0 litres (44.09 lb) of Fuel reserve tank 1.5 litres (3.30 lb) of Brake fluid 7.5 litres (16.53 lb) of Window washer and xenon headlight cleaner mixture ----- 161.4 litres (355.82 lb) (including a full tank of fuel) ----- As already indicated the DRY weight (without the above fluids) of the lightest 360CS with no stereo, no electric windows and no xenon lights and no driver was 1180kg. This figure however is VERY misleading, especially when used to calculate a Power to Weight Ratio!!! In reality you get closer to this; 1180 kg's (2601.45 lb) dry weight 25 kg's ( 55.11 lb) *(adding stereo, xenons and electric windows back in) 161 kg's ( 355.82 lb) *(assumes full fuel tank) ----- 1,366 kg (3,011.51 lb) ----- Then add a driver in to the mix; 75 kg's (165.34 lb) driver weight (68kg (149.91 lb) driver - do you weigh more?? and 7kg lugguage (15.4 lb) ) ----- 1,441 kg (3,176.86 lb) ----- And if you add in a passenger too; ----- 1,516 kg (3,342,20 lb) <--- worst case scenario (with 75kg driver & passenger) ! ----- Obviously if you assume only the fuel reserve tank full (automatically adds 20 litres) and say only 20% (19 litres instead of 95!) worth of a full tank without a passenger and with no luggage things look much better; 1180 kg's (2601.45 lb) dry weight 25 kg's ( 55.11 lb) *(adding stereo, xenons and electric windows back in) 85 kg's ( 187.39 lb) *(includes fluids and assumes only 20% filled fuel tank) 68 kg's ( 149.91 lb) driver weight (68kg (149.91 lb) driver, no lugguage) ----- 1358 kg (2,993,87 lb) <--- best case scenario for CS's with Stereo, Windows & Xenons and a only 20% full fuel tank ----- 1180 kg's (2601.45 lb) dry weight 85 kg's ( 187.39 lb) *(includes fluids and assumes only 20% filled fuel tank) 68 kg's driver weight (68kg driver, no lugguage) ----- 1333 kg (2938.76 lb) <--- best case scenario for no stereo, lexan side windows and a only 20% full fuel tank ----- So as you can see from these findings weight can differ VERY considerably from car to car.... Thats not even including additional options such as leather, spare wheel, which all can contribute to add even more weight. ---- *Best Case 1333kg (2938.76 lb) *Worst Case Over 1516kg++ (3342.20 lb) ---- *These weights also do not include any additional emissions and bumper regulations weight adding devices required for US Fed law either so the weight could be even higher on the road. Yikes!!! In summary it just goes to show you how much difference it makes to never fill your fuel tank 100% full if you intend to take your CS on the track, oh and ditch the passenger also
Thanks Keith, Can you provide a little more information. Also any other CS drivers had their car weighed? Q. Was that DMV certified scale weight without the driver? Q. Do you know the weight of the US spec cats that where removed vs weight of the anti-cat pipes you had fitted? (so we can work out the difference in weight saved) Q. What specs has your car had fitted from factory? 1. Fire Extinguisher? 2. Stereo? 3. Spare Wheel? 4. Fabric or leather interior spec? I know that all the US cars all had standard side glass windows and electric lifters (no lexan with flap). Very Interesting! Looks like we are finally getting to the bottom of all this now!
I will next time on track. However my friends Gallardo spider was with passenger close to 1,900kg´s before he entered the track, so fluids, extra toys and passenger is ALOT of extre weight.
Easily over 120kg's [264lbs] removed to date. Probably a lot more actually. I'll find out when I corner weight it before I do a proper track day outing soon. I have done some pretty major weight strip out recently including all the sound deading material from removal of the carpets so I cannot wait to find out. Incidentally the carpets themselves are only a mere 1.3kg's per side, [2.8lbs] so they are light as a feather (so I chuckle when people suggest the weight reduction was due to removal of the carpets, erm, sorry but no.). The sound deading and carpets combine to save a total of just 8kg's [17.6lb] which is less than that saved from the gel battery swap. You save more from just junking the battery tray and cover! Not to mention I've shed at another 40kg's [88lbs] more reduction than a stock Strad from just things like ultra light titanium exhaust, race battery and removal of toolkit and tyre foam, etc. Ferrari easily could have junked 150kg's [330lbs] from the Strad but held back in fear of making it faster than their newer model, the F430 around Fiorano.
Trev- The 2004 US owners manual has 3000 lbs/1360 kgs, consistent with what private owners are getting and you estimated. Taz Terry Phillips
