The Great LaFerrari Dry Weight Mix-up

LaFerrari was presented in 5th of March 2013 in Geneva Motor Show. To my knowledge Ferrari never gave any weight figure for the car, but somehow the press concluded that its dry weight was around 1255 kg, i.e. same as dry weight of Ferrari Enzo.

One of the first to do so was Autocar, which shared this image on the launch day:

This can be seen in ferrarichat launch thread of LaFerrari in forum post:

However, Ferrari did claim that its chassis was 20 % lighter as in Enzo. This is evident in YouTube video:


Also much earlier, In Paris auto show in September 27th 2012, Ferrari showcased the carbon chassis of the forthcoming LaFerrari and shared a press release which is still visible here:
https://www.autoblog.com/2012/09/28/ferrari-f70-enzo-carbon-fiber-chassis-paris-2012/

"The overall chassis is 20 percent lighter than the Enzo Ferrari, despite the extra weight required by housing the hybrid components and to meet regulatory obligations. Torsional rigidity is increased by 27 percent and beam stiffness is up by 22 percent."

Autocar later informed more details about weight of battery and motor:

"But also behind and beneath the seats sits a 60kg lithium ion battery pack which, via a 25.7kg electric motor, provides a further 160bhp and 199lb ft to give combined outputs of 950bhp and 715lb ft."

Apparently the combined weight of battery pack and electric motor (85.7 kg) is still not the complete hybrid system weigh. Evo magazine states this:
https://www.evo.co.uk/ferrari/laferrari/13921/laferrari-v-mclaren-p1-how-the-hypercars-stack-up

"The electrical side of the powertrain consists of an ultra-compact Samsung lithium-ion battery pack, situated in the floor and supplying current to a motor mounted behind the transmission and driving the differential directly. A secondary generator, effectively a big alternator, recharges the battery from the engine. The electrical system adds 140kg in weight, the battery being 66kg, yet Ferrari says the car will weigh ‘about 1300kg’ (the Enzo was 1365kg). Total combined power is 950bhp."

It is not clear to me if Ferrari has mentioned any overall weight figure even verbally, but somehow the dry weight of Enzo (1255 kg) ended up being also LaFerrari's dry weight figure and shared all over the internet and magazines. And as it was later found out, this figure was almost 200 kg too optimistic, as discussed in thread:

If anyone knows more about the subject, please share.

 

Perhaps Ferrari now tries to restore the trust, as the dry weight figure for Daytona SP3 is so high that it might be actually real.

 

I suppose this is the most accurate weight figure for LaFerrari hybrid system that has been mentioned:

https://www.evo.co.uk/ferrari/ferrari-laferrari
Together with the batteries, the combined weight of the hybrid system is 146kg - roughly half that of the admittedly beefier 918 Spyder’s hybrid system. It more than pulls its weight, improving acceleration by 20 per cent and delivering a 50 per cent reduction in CO2.

Then again, according to Autocar, the battery pack weights 60 kg while Evo says its 66 kg, so I assume total hybrid system weight is either 140 or 146 kg depending the source.
