Lamborghini Terzo Millennio: Why Supercapacitors Define the Electric Supercar Problem
A concept born not at a motor show, but inside one of the world's foremost engineering universities.
Lamborghini unveiled the Terzo Millennio at MIT's EmTech conference in Cambridge, Massachusetts in November 2017, aiming at the hardest unsolved problem in electric supercar development: how to store and release energy fast enough to make an electric Lamborghini feel like a Lamborghini.
From concept compass to production hybrids
The Revuelto, Lamborghini's current V12 flagship, moved to a plug-in hybrid architecture with three electric motors and a conventional battery pack, suggesting the company recognized that pure supercapacitor technology was not yet ready to carry a production car's full energy burden.
Supercapacitor roots in the Aventador
Low-voltage supercapacitors appeared in the V12 Aventador five years before the Terzo Millennio's unveiling, handling stop-start system duties where their rapid charge and discharge characteristics made them a natural fit.
The body-as-battery ambition
Prof. Hart's Mechanosynthesis Group at MIT is investigating new manufacturing routes for carbon fiber materials that would make the bodyshell double as an energy accumulator, eliminating the weight and packaging penalties that make conventional batteries hostile to supercar architecture.
In-wheel motors reshape the architecture
Lamborghini says the in-wheel motor layout produces a design that represents "a radical expression of aerodynamic supremacy, based around an entirely new architecture, totally dedicated to perfecting airflow."
Replacing the V12's drama with physics
Instantaneous torque delivery, individually controllable at each wheel, could theoretically produce a level of directional agility that no mechanical differential can match.
Competitive stakes for buyers and collectors
Lamborghini's electrification strategy is not a reluctant concession to regulation — the Terzo Millennio staked out intellectual territory as the supercar manufacturer willing to question the most fundamental assumptions about how electric performance cars should be built.
MIT's EmTech stage, not a motor show
Lamborghini chose to unveil the Terzo Millennio concept at MIT's EmTech conference in Cambridge, Massachusetts in November 2017, and the venue told you everything about the car's purpose as a research declaration.
The Sián proved the supercapacitor thesis first
The Sián FKP 37, which arrived in 2019, used a supercapacitor to supplement its V12 rather than a conventional lithium-ion battery, making it the first production hybrid to do so at that power level.
The energy density gap
A supercapacitor array powerful enough to launch a supercar to extreme speeds can deliver ferocious bursts, but sustaining that performance over a meaningful range requires a breakthrough in how much energy these devices can hold.
Self-healing carbon fiber structure
Lamborghini says the Terzo Millennio targets continuous monitoring of the entire carbon fiber structure, both visible surfaces and hidden substructure, to detect cracks and activate a self-repairing process through micro-channels filled with healing chemistries.
Four integrated motors, zero driveshafts
Each of the Terzo Millennio's four wheels incorporates an integrated electric motor, preserving all-wheel drive while exploiting high torque from zero rpm, reversibility for regeneration, and the elimination of mechanical driveshafts.
From research concept to production reality
The Terzo Millennio, the Sián, the Revuelto, and the Temerario form a coherent progression from research concept to hybrid production cars, each incorporating more electrical capability while fighting to preserve what makes the brand worth caring about.
