1901 Lohner-Porsche Mixte – Exterior and Interior – Classic Expo Salzburg 2021
At the beginning of the twentieth century, the automobile industry was still searching for the most effective form of propulsion. Steam, gasoline, and electricity all competed as possible solutions. One of the most remarkable attempts to combine these technologies came from the collaboration between the Austrian carriage manufacturer Lohner and a young engineer named Ferdinand Porsche. The Lohner-Porsche Mixte represents one of the earliest hybrid vehicles ever built.
Technical Details
The 1901 Lohner-Porsche Mixte was a hybrid electric vehicle that combined an internal combustion engine with electric propulsion. This unusual system was developed by Ferdinand Porsche, who had already gained attention for earlier electric vehicles equipped with wheel hub motors.
In the Mixte configuration, a gasoline engine was used not to drive the wheels directly but to power an electric generator. This generator supplied electricity to electric motors mounted in the wheel hubs. These motors drove the wheels directly, eliminating the need for a conventional transmission or driveshaft. The concept corresponds to what is now known as a series hybrid drivetrain.
The electric wheel hub motors were a distinctive feature of Porsche’s early designs. Each motor was integrated into the wheel itself, allowing direct drive without mechanical gearing. Early versions used two motors on the front wheels, while later variants could be equipped with four motors, effectively creating one of the earliest examples of four-wheel drive in an automobile.
The vehicle also included a battery system, which helped regulate electrical supply and allowed limited operation even when the engine was not producing power. However, the batteries were heavy and represented one of the main technical limitations of early electric propulsion.
The combined system produced approximately 5 to 7 horsepower depending on configuration. Although modest in output, this power was sufficient to move the relatively heavy vehicle at speeds approaching 50 km/h under favorable conditions. The technical concept was remarkably advanced for the period, anticipating drivetrain solutions that would only become common more than a century later.

Design
The design of the Lohner-Porsche Mixte reflected the transitional nature of early automobiles, combining traditional carriage construction with emerging automotive technology. The body sat on a sturdy chassis and was typically built as an open touring vehicle, allowing multiple passengers to sit in relative comfort.
Large spoked wheels dominated the exterior appearance. Because the electric motors were integrated directly into the wheel hubs, these wheels were significantly heavier than those of conventional cars of the period. Despite this technical complexity, the vehicle’s outward appearance still resembled a refined horse-drawn carriage.
The seating arrangement generally followed a forward-facing layout, with the driver positioned at the front and passengers seated behind. Steering was controlled through a steering wheel, which had largely replaced the earlier tiller systems used in nineteenth-century automobiles.
The bodywork emphasized craftsmanship rather than industrial standardization. As with many vehicles of the era, construction often involved wood framing combined with metal panels and upholstered seating. Lamps mounted at the front of the vehicle provided illumination for night driving and were typically powered by oil or acetylene gas.
Historical Significance
The Lohner-Porsche Mixte occupies an important place in automotive history because it represents one of the earliest hybrid vehicles ever developed. Ferdinand Porsche had already attracted attention at the 1900 Paris Exposition with the Lohner-Porsche electric car, which used wheel hub motors powered entirely by batteries. However, the limited capacity and heavy weight of batteries made purely electric vehicles difficult to operate over longer distances.
The Mixte system addressed this limitation by adding a gasoline engine that functioned as a generator, producing electricity to power the motors. This eliminated the need for a mechanical transmission and allowed the vehicle to combine the advantages of electric propulsion with the extended operating range provided by the combustion engine.
The concept was highly innovative but also complex and expensive. As a result, only a small number of Lohner-Porsche Mixte vehicles were built. Nevertheless, the technical ideas behind the design were decades ahead of their time. The combination of an internal combustion engine, generator, battery system, and electric motors anticipated hybrid systems that would only become widespread in the late twentieth and early twenty-first centuries.
For Ferdinand Porsche, the project also marked an important early step in a career that would later include the development of numerous influential automobiles and the founding of the Porsche brand.
Quirks and Pop Culture
One of the most remarkable aspects of the Lohner-Porsche Mixte is how closely its drivetrain concept resembles modern hybrid vehicles. Although developed in 1901, the principle of a gasoline engine generating electricity to power electric motors is essentially the same as the series hybrid systems used in some contemporary cars.
Another unusual characteristic was the use of electric motors integrated directly into the wheels. While technically elegant, these wheel hub motors made the wheels very heavy, which affected ride quality and suspension performance. Nevertheless, the idea of hub-mounted electric motors continues to attract engineering interest even today.
Because of its innovative technology and association with Ferdinand Porsche, the Lohner-Porsche Mixte has become a well-known example in the history of electric and hybrid vehicles. Surviving examples are displayed in museums and are frequently cited in discussions about the early origins of hybrid propulsion.
Display and preservation
The vehicle was exhibited at the Classic Expo Salzburg in 2021. As one of Austria’s premier classic car events, the show has established itself as a central meeting point for collectors, restorers, and enthusiasts from across Central Europe. The 2021 edition took place at Messezentrum Salzburg and featured more than 250 exhibitors, along with a strong turnout of over 20,000 visitors. Attendees could explore a broad range of offerings—from historical vehicles and motorcycles to automobilia, spare parts, and literature.
Conclusion
The 1901 Lohner-Porsche Mixte stands as one of the most technologically advanced automobiles of its time. By combining a gasoline engine generator with electric wheel hub motors, it created an early hybrid drivetrain more than a century before such systems became common. Although produced in limited numbers due to its complexity and cost, the Mixte demonstrated an extraordinary level of engineering innovation. Today, it is recognized as a pioneering milestone in the development of hybrid and electric vehicle technology.
