Above this post are the acceleration figures.
cubic inches (cui)
max rpm (rpm)
volumetric efficiency % (VE)
84 [benchmark between a 2- and 4-valve engine, since this V12 is a 3-valve one]
horsepower target (bhp)
corrected displacement (atmospheric equivalency)
748 (bigger than GM's ZZ632 Big Block!!)
Engine size: 748 cihttp://hpwizard.com/car-weight.html
Driver mass: 0 kg
Type: Race car (prod. model)
Total mass: 1534 kg
If I swapped 748cui for 364.933cui, I get a 1077kg curb weight figure, as opposed to 1534kg. Half of these two curb weight figures added equal to 1305.5kg, but this is still slightly higher than Pagani's dry weight figure of 1250kg. Therefore, (1306+1534)/2 = 1420kg curb weight. Very close to what Car & Driver got (1384 kg), but also very close to what Quattroruote got (1423 kg not including driver).
Things I selected in HPWizard: well-rounded, low-squared-sloping-up, high-scuttle-rounded-top-wings, bowed windscreen (plan), rounded windscreen (peak), constant canopy width (plan), semi-fastback style, lower rear quarters are of constant width (leaning towards outward taper), monocoque design (MR layout), perfectly smooth body, worst design (I selected that on purpose since it is an extreme track toy), convertible body style, 265-30-20 front and 355-25-21 rear tires, race car production model with high downforce, 2035mm wide x 1169mm high
==== 1.95m2 frontal area, 0.93m2 drag factor, -0.98m2 lift factor, 0.476Cd drag coefficient
Pretty similar to a Dodge Viper ACR or maybe a McLaren Senna (although a drag coefficient figure was never released for the Senna).
