Don't you want a car that can't traverse speed bumps though?

#42What's with all the auto-playing videos these days? I don't even know how to turn this video off....
Turn off autoplay in 10 seconds (Firefox): (1)Open a new tab to about:config (2)Type in autoplay (3) Double click the obvious one. Done.

#43> the company will develop in-wheel electric motors, which would eliminate the need for a single large engine. A 'single large engine' is only needed in ICE cars, electric vehicles have a 'small' motor, and can easily have multiple motors. It's already being done by Tesla and Rimac. To my knowledge, an 'in wheel' motor would not be desirable due to unsprung mass, so a motor on the chassis connected to the wheel with…
Also, an in-wheel electrict motor would:
1. suffer a lot more from wear and tear than a motor mounted to the chassis.
2. restrain the amount of space available for brakes. While it would be reasonable to say that a small city car could forego its rear brakes and use electric motors instead to deccelerate, coupled with brakes at the front, a four wheel drive supercar with four electric motors would have no chance relying simply on the stopping power of those motors and no brakes.
3. be very difficult to connect to a powerful cooling system. Even electric motorcycles with 30-40 bhp rely on water cooling, let alone a car 20 times the weight.
4. need serious protection from water damage.

#45This is a concept and the article mentions that many of the technologies do not yet exist.
Thanks, we've added “Concept” to the title to clarify.

#47> Supercapacitors store energy physically and don’t generate the heat of lithium-ions, but as of yet they don’t offer as much power. This probably should read "don't offer as much energy". Almost every mainstream media article about electric cars mixes up these two concepts, sigh.
No they actually mean power. Supercapacitors can energy faster than lithium batteries can(more power). While batteries have power densities hundreds of watts per kilogram, supercapacitors can release thousands of watts per kilogram. Now if we ignore the bullshit with carbon fiber supercapacitors it sounds like what lambroghini really wants is an energy storage system with more energy density and power density than we have today.
Integrating something with a high power density into a vehicle frame might not be such a good idea. If we really do get capacitor level power densities, then the stored energy in the frame could be released really fast during a crash. If the stored energy is enough and released fast enough we essentially have a bomb. There is even the potential for the energy release to cause a relatively localized EMP.

#48So if the carbon fiber body is going to be a capacitor, wouldn't there be a risk of electric shock in case of some damage to it?
No, because the capacitors discharge very fast. The problem is they want capacitors that discharge fast and have a high energy density, which means that during such a crash we could get an explosion or maybe even an EMP.

#50> Lamborghini also intends to make the supercapacitors out of carbon fiber panels that can be used to form the body of the car—so the Terzo Millennio draws energy from its own body. In other words: the car itself is the battery. So does that mean that if you happen to have an accident, there is a chance that a good chunk of your battery gets short circuited? That sounds somewhat dangerous...

Good to see Lamborghini going back to their roots )
