So if a realistic "green" electrical car isn't possible, how come Porsche had a competitive electric car all the way back in 1900? Something definitely doesn't mesh. This year at the Los Angles Auto Show Porsche is not only going to show its dedication to going green by showing the Porsche Cayenne Hybrid SUV (which is already one of the major topics of the auto world), but maybe its earliest sister: the 1900 Porsche electric car, which was later modified to use electricity and gas, making it the first true hybrid automobile.
Why the trip down memory lane? For one, it's a perfect public relations comparison, and it helps highlight Porsche's understanding that as the environment continues to become a bigger and bigger concern that the demands for fuel efficiency and more environmentally friendly cars will continue. Another bragging point is the fact that the original electric Porsche was designed by the founder himself, Ferdinand Porsche, and won the award for "most innovative invention" at the Paris World's Fair in 1900.
This electric car was different from modern versions because it had an electric motor in each front wheel, meaning that though simple, the design was efficient, allowing 83% of all energy expended to go directly to moving the car, as opposed to about 40%, which is roughly the amount used by the average modern internal combustion engine. The car back then went at a top speed of about 30 mph, and different racing versions of it went up to 37 mph, with races often won by Porsche himself. This was a good speed for the time.
The electric Porsche was in trouble because batteries in those days had severe limitations, so to answer this, Porsche added a gasoline engine to create the first Hybrid car. Eventually some of these cars got up to 56 mph-a crazily efficient rate for cars in the first few years of the 20th century.
As the hybrid cars and SUVs are proving far more popular than most car companies originally thought, the trend for more and better hybrids will continue, and after a nearly 100 year hiatus, it looks like the environmentally green branch of cars has made a comeback that's here to stay. When Porsche makes a hybrid SUV, you know, as the old Bob Dylan song goes, that time's they are a' changing. The hybrid cars are here to stay.

Post a Commentgas actually uses much less than 40%. Internal combustion is actually more like 10-15% depending on outdoor temperature. It's first year university physics.
Kent is basically correct in that there is no current, practical, mass-marketed battery that can effectively compete with a gasoline engine in terms of range, speed, re-charge/fill-up time, and price. However, due to global warming concerns, and rising governmental and consumer demand the day of the electric car is coming. There are so many people working on this and so many incentives for achieving this goal, it is only a matter of time. And the last car companies to try to develop electric cars will probably have to end up turning out their electric lights in their car manufacturing facilities for good.
If anyone is gullible enough to believe that an electric car utilizes 84% of its energy while a gasoline only uses 40%, then they are not qualified to even have an opinion about car technologies, let alone spout them to the public. In fact, the electricity that powers the car represents about 50% of the energy
stored in the fuel used to make electricity, and the electric car loses even more energy in storing the energy and then in retrieving it from its battery.
The failure for the past 100 years of the electric car can be summed up in one word : batteries. Without a
practical battery there is no such thing as a practical electric car. We don't yet have an affordable, high capcity, fast recharge , lightweight battery to enable an all-electric car. Rightnow only plug-in hybrids like the Chevy VOLT make both economical and environmental sense. A 40 mile plus electric driving range can accomplish virtually everything that an all-electric can in terms of avoiding oil and carbon emissi
