Porsche was founded on Apr. 25, 1931 by Ferdinand Porsche, Adolf Rosenberger and Anton Piëch in Stuttgart, Baden-Württemberg, Germany. The company is an automobile manufacturer specializing in luxury, high-performance sports cars, SUVs and sedans. It has been reported in 2022 that Porsche had €37.630 billion Euros in revenue and a total of 39,162 employees. For 2022 alone, their production output totaled 321,321 vehicles. On Oct. 10, 2019, Porsche and Boeing announced they signed a Memorandum of Understanding to explore the premium passenger electric vertical takeoff and landing (eVTOL) aircraft for the urban air mobility (UAM) market, now called advanced air mobility (AAM) market and the extension of urban traffic into airspace.

In Sept. 2015, Porsche unveiled the Mission E all-electric concept sports car at the Frankfurt International Motor Show in Germany. Of note, the Mission E electric concept car can go from zero to 100 km/h (62 mph) in less than 3.5 seconds and inside, there is an intuitively operated by eye-tracking and gesture control system including using holograms. In Jun. 2018, the electric sports car got its official name, the Porsche Taycan. On Sept. 4, 2019 Porsche releases the production version with deliveries expected before the end of 2019. With that said, Porsche has the technical know-how to design and manufacture electric road vehicles. In March 2018, Porsche published a white paper on The Future of Vertical Mobility.

Porsche is looking to enhance its scope as a sports car manufacturer by becoming a leading brand for premium mobility. In the longer term, this could mean moving into the third dimension of travel. We are combining the strengths of two leading global companies to address a potential key market segment of the future. — Detlev von Platen, Member of the Executive Board for Sales and Marketing at Porsche AG, Porsche press release, Oct. 10, 2019

Three companies, Porsche, Boeing and Aurora Flight sciences, will be working together to design and create the eVTOL premium personal air vehicle. While the initial design which Porsche and Boeing created and revealed to the public on October 10, 2019, one can expect this design to change over time based on refined requirements by lead management, engineers, mission requirements and technological constraints.

As of Oct. 11, 2019, there is an international core team of 20 people located in St. Louis (USA), Stuttgart (Germany), and Lucerne (Switzerland) designing the eVTOL aircraft. The team consists of business development personnel, engineers and designers. This is the first time Porsche has explored Urban Air Mobility and discussions began in the summer of 2019.

A 2018 study by Porsche Consulting forecasts that the urban air mobility market will pick up speed after 2025. The study also indicates that urban air mobility solutions will transport passengers more quickly and efficiently than current conventional means of terrestrial transport, at a lower cost and with greater flexibility. –Porsche press release, Oct. 10, 2019

Unnamed (T2) luxury passenger eVTOL concept design aircraft
The Unnamed (T2) is an autonomous luxury two passenger eVTOL concept design aircraft that is very modern in design. The aircraft would have room for two passengers and their luggage. It is unknown if the aircraft could be switched over to manual piloting. (T2, or 2 tilt electric ducted fans, is a designation we had to give the aircraft to distinguish it from several other Porsche eVTOL concept design aircraft.)

While very few specifications were revealed for the concept design aircraft, one of the Porsche brochures estimated the cruise speed of passenger eVTOL aircraft would be approximately 200 km/h (~124 mph). This concept design aircraft has two front VTOL-only electric ducted fans (EDFs) inside the blended wing body of the aircraft and has two rear tilting EDFs that are used for both VTOL and forward flight. The rear two EDFs will most likely also tilt rearward (both would tilt independently of each other) allowing the aircraft to travel in all directions. The aircraft either has four or eight electric motors and are powered by easily removed fast-charging high-performance battery packs.

The aircraft has panoramic wrap around windows allowing forward, left and right visibility for spectacular views with a solid roof above the passenger compartment. The aircraft has one main low blended wing body. The ends of the main wing fold down vertically when the aircraft is landing which makes the landing area of the aircraft smaller and the bottom of the wing tips also act as landing gear. The wing and fuselage is made from carbon fiber composite for a high strength and low weight ratio. The aircraft has one vertical stabilizer. The aircraft lands on the bottom of its foldable wing tips.

Working prototype targeted for 2020
Porsche has an ambitious plan to fly a working prototype in 2020. Very few details have been released about their eVTOL aircraft except that the personal air vehicle is currently planned to be 100% electric, will carry two passengers, will be a premium priced personal aircraft, will be well styled and will be an autonomous aircraft but will able to be flown manually if any passenger has the proper training to fly an aircraft.

Porsche patents
Porsche applied for a patent for an eVTOL aircraft on Jul. 3, 2019, and a patent for a power supply for an aircraft and corresponding aircraft on Jul. 2, 2019. Both patents were published online on Jan. 9, 2020. The aircraft patent reveals the eVTOL has four ducted propellers. Two (2) sets of ducted propellers are on each side of the fuselage, in the front of the aircraft and two sets of ducted propellers on each side of the fuselage, in the rear of the aircraft. While at rest, the propellers are hidden by louvers. When the aircraft is in forward flight, only the back set of ducted propellers are used for forward flight and the front set of ducted propellers turned off and louvers close over them, for better aerodynamics.

One additional design concept revealed from the power supply for an aircraft and corresponding aircraft patent is when the eVTOL takes off, it is tethered to a smaller auxiliary drone with a battery as the drone's cargo. The eVTOL and battery drone take off together autonomously while the battery drone feeds electric power to the eVTOL (and the battery drone itself) for vertical flight until the eVTOL passenger aircraft transitions to forward flight. After the eVTOL passenger aircraft transitions to forward flight, the auxiliary drone releases itself and apparently returns to the landing pad where it took off. However, the patent doesn't give any specific details where the battery drone will land and recharge itself. (This patent could be for the eVTOL passenger aircraft or for other aircraft they are designing.)

October 2019 update
Currently the discussions by Porsche and Boeing is the aircraft's main function will be for personal urban air travel. There has been no talk about this eVTOL aircraft being used as a ridesharing air taxi. Also, no other versions or models are being discussed at this time.

Future
According to some news reports, this unnamed eVTOL concept design aircraft was cancelled due to the Covid-19 pandemic. The company predicts the future of Vertical Mobility or advanced air mobility (AAM), will include person eVTOL aircraft, on-demand air taxis, eVTOL rentals, eVTOL buses and eVTOL rescue operations. The company predicts the target date of a high volume eVTOL aircraft flying worldwide will be by 2035.

• Aircraft type: Passenger eVTOL concept design aircraft
• Piloting: Autonomous
• Capacity: 2 passengers
• Cruise speed: ~200 km/h (~124 mph)
• Propellers: 4 electric ducted fans (EDFs). 2 EDFs are VTOL-only, 2 EDFs rotate for VTOL and forward flight. The front 2 VTOL-only EDFs have louvers that close during forward flight, providing a more efficient aerodynamics during forward flight.
• Electric motors: 4 or 8 electric motors
• Power source: Easily removed fast-charging high-performance battery packs
• Fuselage: Carbon fiber composite
• Windows: Panoramic wrap around windows allowing forward, left and right visibility for spectacular views with a solid roof above the passenger compartment
• Wings: 1 blended low wing body with foldable wings for storage and landing purposes
• Tail: 1 vertical stabilizer
• Landing gear: Lands on the ends of the wing tips
• Safety features: Distributed Electric Propulsion (DEP) means having multiple propellers (or electric ducted fans) and multiple electric motors on an aircraft so if one or more propellers (or electric ducted fans) or some electric motors fail, the other working propellers (or electric ducted fans) and electric motors can safely land the aircraft. DEP provides safety through redundancy for passengers or cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.
