Sounds pretty cool:
"The 6 is the first car in America to capture energy in a fast-charging capacitor with no rare-earth metals, rather than a slower, bulkier and harder-to-recycle battery. Lift off the gas, and the optional i-Eloop system spins the alternator to charge the capacitor in eight seconds flat. The stored juice — roughly 2,000 watts — then powers the electric system and accessories. E.V. and laptop users, take note: unlike lithium-ion batteries, Mazda’s capacitor is designed to charge and discharge millions of times with no loss of storage capacity."
How much power is this and how long might it power the electrical system and accessories?
