Lamborghini chief technical officer Maurizio Reggiani says the Aventador successor won’t feature the advanced supercapacitors of the Sian FKP 37 that was unveiled last week in Frankfurt, and instead use a more traditional hybrid powertrain.
The system used by the Sian adds 34 hp to the supercar and weighs just 34 kg (75 lbs). Reggiani says it works perfectly for a low-volume car like the Sian as a means to improve performance, but isn’t up to scratch for a series-production road car that needs a reasonable amount of all-electric range to meet CO2 emissions.
“With a supercapacitor you can accumulate in the same space three times as much power as a battery. However, it’s clear that at the moment a supercapacitor cannot guarantee that you have the range to do even 5-10km in full-electric mode. The storage is not enough,” he told Car Sales.
“For the Sian, given that it was the first application of hybridization in a Lamborghini it was more important to say what is the DNA of a supersport car. So, the focus was to improve the performance while being as light and compact as possible. The answer to this was the supercapacitor”, he explained.
According to Reggiani, the automaker will develop a different hybrid system for the Aventador successor that can also be used for the replacement to the Huracan.
“With a car that sells in the volumes that the Aventador does, there is another point that you need to take in consideration that relates to CO2 emissions. If you want to attack CO2, you need to have a battery that guarantees a certain range of full-electric mobility. With the supercapacitor as it is today, you cannot have this.”
The Aventador successor will get most of its power from a naturally aspirated V12, while added grunt will be provided by at least one electric motor. Lamborghini will also ditch the outdated independent-shifting rod (ISR) single-clutch transmission for a new dual-clutch ‘box.
