Lohner-Porsche
1989

In the year 1898 when a new century was ready to begin and nobody had heard about the Y2K effect, Jakob Lohner a coachbuilder who owned the " k.u.k-Hofwagenfabrik Jakob Lohner & Co ", with manufacturing facilities in Florisdorf , Vienna , decided that it was the right time to build and sell a modern " horseless carriages " to bring such vehicles up to date, offering the latest technical developments to his distinguished customers among them the House of the Hasburgs .
Lohner disliked " the new horseless carriages " powered by explosion engines that were beginning to run around the roads because he considered that they were too rude, dirty and noisy for his aristocratic customers.
In order for the project to come through safely, he hired as chief engineer a 25 years old, engineer , named Ferdinand Porsche , who as a student of the Imperial Technical School of Reichenberg , had learned and experienced with youthful enthusiasm with electricity as a propulsive energy.
The brilliant ideas usually are the simplest and the more beautiful ones, and this was the case of the propulsion system devised by Porsche for the new Lohner electrical vehicle.

Porsche placed two electrical motors as bushings of the front wheels in such a way that its rotors turned with the wheels, whereas both stators were fixed by a rigid axis and to the suspension.
Therefore there was no need of drive shafts, transmission, gears, straps, chains,or clutch. Due to its extreme simplicity the transmission operated, therefore, without losses produced by mechanical friction with an incredible yield of 83%.
When it first appeared in the World Exhibition of Paris , in April 14th ,1900 , the Lohner-Porsche with electrical motors astonished the automobile world and was an authentic novelty for the automobile fans of that time.
Ferdinand Porsche himself made a demonstration trip with the new vehicle traveling from Versailles to the Exhibition , which was worth a Great Prize to him.
The innovating success of its design catapulted him to the fame as engineer, whereas Lohner received orders for a later production of 300 of these vehicles, becoming a wealthy man, afterwards he sold his patent to Emil Jellinek
The headlines of a specialized magazine of the time said " the new development, sets a new landmark ", " it eliminates all the intermediate mechanisms completely like the gears, chains of transmission or the differentials. All in all, this it is the first car that it does not use a traditional system of transmission. "
The specialized press of that time considered the Lohner-Porsche a vehicle particularly safe to drive, " since it doesn't spins-off in tight turns or slips in muddy streets . "
Each one of the motors of the Lohner-Porsche vehicle developed 7 CV power during 20 minutes , althoughthe normal power was 2.5 CV at 120 r.p.m. . A battery of 44 cells of 330 ampers per hour and 80 volts provided the vehicle a range of 50 kilometers . The minimum speed was 17 km/h , cruising speed 37 km/h and the top speed was 50 km/h . the vehicle had an electrical front brake , whereas in the rear axis it was fitted with a mechanical brake with an iron strap . It also incorporated safety mechanisms in the rear axis to avoid the car sliding backwards in the hills.

The wheels had wooden spokes with a diameter of 650 mm in the front and 950 mm in the rear. The vehicle weighed 1 ton , attributable in a great part to the battery that weighed 410 kg , and to the front wheels with motors, that weighed with their rotors 110 kg each one.

Depending on its design, equipment and motor, the Lohner-Porsche had a price that oscillated between 10,000 and 35,000 Austrian crowns , this was pretty much more expensive than a car with a combustion engine. The rich, famous, and aristocrats became, in the following years, their main users. The Viennese coffee tycoon Julius Meint , Margrave Sandor Pallavicini , Emil Jellinek , father of Mercedes (Daimler agent in Nize), the automobile company Panhard-Levassor of Paris, Prince Egor von Fürsrstenberg , the cinema pioneer Ludwig Stollwerk , the banker Baron Nathan Rotschild ,Prince Max Egon von Thurn und Taxis were all owners of Lohner-Porsche vehicles .

Porsche always considered that motor racing was a good way to test and improve its designs so that same year ( 1900 ) he developed and build racing cars in Florisdorf with bush electric motors . In one of them, only the batteries weighed 1,800 kg . , Porsche personally delivered this car, that reached a top speed of 60 km/h , to its buyer, driving it himself to Luton, in the north of London, to his new owner E.W. Hart .
The Apolo space missions, the NASA used this concept of electrical motor to drive its lunar vehicle. The invention of Professor Ferdinand Porsche is still used at the present time, the electrical company Canadian Hydro-Quebec has presented and displayed an electrical vehicle with a transmission system developed from the invention of Porsche . Several international automobile companies also are taking advantage of this Porsche idea in their development projects for ecological vehicles.

Looks like the car could use a Tire Pressure Warning System! biggrin.gif
