The French-Romanian carmaker Dacia Renault to increase production
Prof. Ferdinand Porsche created the first functional hybrid car.
He developed the first hybrid car in the world, electric car and advanced all-wheel drive car it was a century ago, and now Porsche brings a recreation of the Semper Vivus in New York.
NEW YORK April 20, 2011 The name Porsche has been associated with innovations in automotive engineering avant-garde since the beginning of the last century in 1900 Prof. Ferdinand Porsche unveiled his Lohner Porsche, an electric car with hub motors driving wheel front wheels Soon after, this car featured all-wheel drive and brakes four wheel drive, another world first a highlight of his early years as a car designer was the Lohner-Porsche Semper Vivus that went into the story 111 years ago as the first functional hybrid car.
The Semper Vivus recreation alive Porscheâ of a tribute to visionary invention Prof Porscheâ Fully functional Semper replica Vivus, from original drawings and exhaustive search, is a collaborative effort between Porsche Engineering and Karosseriebau Drescher, a construction company cars based in Hinterzarten in Baden-Württemberg WÃ, Germany  this faithful replica, whose visionary design impresses to date, is exposed at the New York Auto Show press day on April 20th.
Professor Ferdinand Porsche was to design and develop its cars in 1896 The first fruit of his efforts was an electric vehicle known as the Lohner-Porsche has been driven by steered wheel hub motors, and it made sense to universal Exhibition in Paris in 1900. This was soon followed by an even more impressive example of the innovative spirit Porsche professor a race car with four electric motors wheel hub has become the worldâ car first AWD passenger and marked the debut of automotive engineering brakes wheel drive no less visionary was the next idea of Professor Porscheâ; in 1900, it has combined wheel hub powered driving battery with a gasoline engine, creating the series hybrid propulsion principle.
Prof Porsche had entered a new territory with the Semper Vivus, first functional car full of worldâ In this hybrid vehicle, two generators paired with gasoline engines formed a single charge unit, simultaneously providing electricity to the hub motors of wheel and the batteries in autumn 1900, Professor Porsche started working on a prototype with hybrid drive petrol-electric Presumably he founded any hybrid car worldâ on a conversion of its electric racing vehicle of the Semmering-Bergrennen race this end, combined its hub motors of electric wheel with two combustion engines and no mechanical connection whatsoever to a drive axle instead, they each conduit an electric generator supplying two wheel hub motors and accumulators with electricity this was the birth of the series hybrid drive as a hybrid concept, Semper Vivus has was also able to cover longer distances on battery power until the combustion engine had to be hired to recharge the batteries.
To save weight and create a space for a gasoline engine, Prof. Porsche permuted accumulator 74 original cells in its Electromobiles for a smaller battery with only 44 cells in the middle of the vehicle he installed two-cooled water May 3 PS2 6 kilowatts DeDion Button gasoline engines - driving two generators to produce electricity - each producing February 5 HP1 84 kilowatts both motors operate independently, each providing 20 amperes at a voltage of 90 volts the electricity generated by the first dynamo flowed to the wheel hub motors, with excess power being sent on batteries another advantage is that it is also possible to use generators as electric start engines for the gasoline engine by reversing the direction of rotation.
In practice, Professor Porsche had yet to address the main problem of its wheel hub Car heavyweight vehicle? Although the total weight of the hybrid cara Semper Vivus was only 70 kg more than the original version, the prototype was 1200 kg challenge for mixing tiresâ soft tire rubber in other respects as well the hybrid concept was still very far to be ready for mass production with its disembodied chassis, presentations gasoline engines and unsprung rear axle, the Semper Vivus may have impressed visitors at the Paris Motor Show in 1901, but potential car buyers must have felt bare-bones prototype was not for them the interaction of the motor, batteries and still need control system of many developing and, in addition to ambitious control technology, a constant problem was the dirt being thrown and fouling accumulators However, the hybrid concept new possibilities that Professor Porsche resolutely began to turn into reality.
In 1901, Prof. Porsche developed the revised concept of the â gasoline-electric hybrid cara in a variant that was ready for series production as the Porsche Lohner-mixed borrowing the French term â Cars mixtesâ With a four-cylinder, engine mounted in the front, this model reflects the concept vehicle Mercedes recently designed by Wilhelm Maybach, but with two wheel hub motors in accordance with the concept of a hybrid car series Prof. Porsche was now using a powerful May 5 liters, 25 ch 18 kilowatts four cylinders of the Austrian Daimler motor company as the electric generator engine was connected by a drive shaft to the electric generator located under the seat, with the control managed by a main controller next to the flywheel direction.
To solve its problems vehiclesâ weight, Prof. Porsche was to constantly reduce the size of the battery while trying to design a sealed battery case to dust While the Joint Lohner-Porsche could drive a few kilometers on electrical power only because of the ability of the reduced battery, the empty weight of the passenger car body four places which fell to about 1200 kg in the normal driving mode of the gasoline engine and a run generator at a rate constant, feeding the wheel hub motors and the battery with electricity at a constant voltage in addition to its CONCEPTA drive high level of efficiency, the car has advantages offered other by reversing the polarity, the generator could be used as an electric starter motor, eliminating the need to hand the intense and dangerous engine start.
Before the end of 1901, Ludwig Lohner and Professor Ferdinand Porsche had torn a respectable income by selling five Lohner-Porsche Mixte cars With a selling price of about 14,000 Krone each, made the cars very exclusive products Buyer this original series was Emil Jellinek, the well-known general agent of Daimler motor company in Stuttgart-rkheim Untertà and inspiration behind the first Mercedes named after her daughter the previous year Despite this contact, an agreement cooperation to provide Mercedes engines failed to materialize and only seven Lohner-Porsche with Daimler engines were built from 1903 the Panhard Levassor gasoline engines were used because the great french carmaker had acquired the license rights for France, the great Britain and Italy Ludwig Lohner.
At the same time, the Porsche professor again significantly altered his training concepts CARSA For reasons of weight and reduce production costs, it provides the purely electric driving ability and shrinks the battery at least to start the engine startup It replaced storing the missing energy unit with another innovation the generator, designed as a fixed armature machine was equipped with an electromechanical speed controller patented as œdevice to automatically regulate the electric generators prof Porsche also ushered in a new development wheel hub motor technology has redesigned casing of the hub allowed kingpins to be relocated closer to the center of the wheel This steering geometry, patented May 1902, reduced significantly the effect of road impacts and the effort required to turn the wheel to reduce the unsprung mass of the wheel, Prof. Porsche also reduces the diameter of its wheel hub motors, it compensates by using wider win ding.
In April 1902, after considering these improvements, Professor Porsche took his place on the starting grid for the Exelberg race his mixed race car two-seater was not only visually impressive due to its modern proportions but impressive on the track and his Lohner- Porsche seemed to cope effortlessly with the road even the steepest gravel April 2 km of unpaved to Exelberg, and it emerged as the winner in the large car class Porsche received additional publicity visibility in autumn 1902 when Austrian Archduke Franz Ferdinand with driver in the Lohner-Porsche at a military maneuver aristocratic passenger seems to have liked the car body with its elegant touring Soon after, Prof. Porsche received a letter from thanks testimony â œjust satisfaction in all respects his Imperial Majestyâ was after the ride.
Despite these impressive demonstrations, sales Mixed production variants remained much lower than expectations With only 11 hybrid cars sold, the return on investment was not up to the enormous costs of technical development between 1900 and the main problem in 1905 was undoubtedly the high selling price depending on the design and equipment, a Lohner-Porsche joint cost between 14400 and 34028 Krone, in some cases making it almost twice as expensive as vehicles comparable engine, conventionally powered This was compounded by the high cost of maintenance of the complex drive system that has not been able to keep pace with increasing the reliability of normal petrol cars of pure electric vehicles however, were economically more successful about 65 electric cars Lohner-Porsche were sold during the first five years of series production at the end of 1905.
In November 2007, the Porsche Museum has launched one of the most interesting and challenging projects in its history, building a faithful replica of the 1900 Lohner-Porsche Semper Vivus Even 111 years after its invention, the construction of the first operating worldâ car hybrid was a big challenge for all Finally, it was not only extreme attention to visual details but also achieving the same performance as the original Porsche Museum entrusted the production to a team of experts led by coachbuilder Hubert Drescher which had already proved its competence in many difficult restoration projects as a number of racing car projects, the aluminum body of Type 64 Porsche museum exhibition comes from the Hinterzarten coachbuilder workshop as well.
extensive research in various archives of across Europe was the first stage The result was a handful of black and white photos and technical drawings using original foundation of the ProjectA As with Prof. Porsche replica Semper Vivus started as a blank sheet of paper This means that, in addition to a lot of imagination, the project required extensive research and calculations to accurately recreate an accurate picture and operation of the electric wheel hub motor as no specification or other documents have survived, experts initially created loan accounts and prepare design drawings on graph paper of the secular way This involved careful and laborious measurement study photos and drawings Since there was not operating wheel hub motor in existence, technical details such as the performance and range evaient be raised and calculated from scratch.
When it came to selecting materials, coachbuilder Drescher took his inspiration, among other sources, coaches and cars from the dawn of the 20th century it took the help of experienced suppliers that have been responsible for manufacturing the special materials fully functioning Semper Vivus replica, which lasted about three years to build, not only includes replica components for example, it is possible to install original components, including combustion engines.
Today, the innovative spirit of Professor Ferdinand Porsche Porscheâ lives aga Center for Research and Development in Weissach, Germany where the company applies its engineering strength to develop various hybrid systems Porscheâ first production hybrid, the 2011 Cayenne S hybrid SUV is selling in many markets, including the United States full parallel hybrid system will be adapted for use in the Panamera S hybrid that goes on sale later this year with an MSRP of 95000 exclude engineers Porsche destination is currently developing its 911 GT3 R hybrid race car to increased competition while continuing work 918 Spyder plug-in hybrid super sports car the company was first shown at the Geneva Motor Show in 2010.
