We have used capacitors as instant voltage stabilizers in big car audio systems for years. You can buy a 5 Farad cap with digital voltmeter for about $ 100 new.
Lamborghini has recently commissioned/collaborated with two departments at MIT to further develop alternative energy storage solutions, including a new type of carbon material that will be used for the chassis and body panels.
Some current super / hyper cars utilize super capacitors as well as electric and gasoline motors, along with batteries for optimal performance. McLaren uses electric motors to stop gap the turbo lag on their older cars, so this entire complex drive system category is rolling full steam ahead, along with battery and capacitor development. The new Chevy CoPo Camaro factory drag racer is all electric, but uses 800V instead of the more common 440 V setups for more power delivery......into a conventional transmission and torque converter no less. Car is rated around 800 hp and runs the quarter mile in 8s or 9s as is de rigeur for the the Mustang Cobra Jet and Dodge Demon non street versions.
Capacitors have much faster current rise times than batteries because it's a field effect, not a chemical reaction that delivers the energy.
Amazing times we live in; despite my penchant for being a dinosaur with carburetors and manual transmission in my toy car, and carbs and 2 stroke engine in my sled.
