Text from the website:
The engine that used is a rotary air engine. It is the invention of the Melbourne engineer Angelo Di Pietro. The engine is compact, lightweight and powerful and runs on compressed air from two compressed air tanks on the bike. It revs up to 3,000 RPM, and because of this, the inventors didn’t need any gear box on the bike. There is only one gear, which is just a sprocket bolted directly to the axis of the engine and chained to the rear wheel.

Compressed air is stored in the bike’s on-board carbon fiber tanks. Once mass produced, the bike will have solar panels that will generate enough energy to compress air and store it in the bike’s tanks, which will increase its range indefinitely.

As the bike was designed as a speed record setter, there is no headlight, brake light or indicator lights on the bike. Instead, there were three little cameras fitted at the front and tail on the bike that are used to record the run. The body works were designed to be aerodynamic and lightweight, and it will be made of fiber glass or carbon fiber.

Some explanation from Edwin :
The exterior desing of the car is inspired by the form of fabric blown in the wind. The form also carries traces of the historical Auto Union Type C Streamline race.

There are no conventional doors on the car, but instead, inspired by the jet fighters, there are three glass canopies. The main canopy opens forward together with the steering wheel and the dashboard; the two passengers’ canopies open backwards; and a side panel on the bodywork opens downwards to act as a step, making the event of getting in and out of the cockpit very special and easy.

The interior is simply one continuous sheet, starting from the dashboard, then being folded and bended to create floor carpet and seat.

The interior of the car is as simple and futuristic as the exterior. Single sheet transparent LCD dashboard displays all the essential data such as speed and mileage. The screen in the center of the steering wheel displays digital map. The information can also be projected on the canopy by a head up display. The
whole driving experience would be like flying a fighter jet. There is a small but handy luggage space behind the driver seat for handbags and suitcases. It is also an arm rest for the passengers.

Four wheels are housed inside the car’s four “legs”. Each wheel contains an Audi In-wheel Electric Drive Unit, making the car an evolution in Audi’s trademark “Quattro” all time four-wheel-drive system. The long range Supercharge-ion battery which powers the in-wheel motors are separated into two packs located in front of as well as behind the cockpit, creating a perfect 50:50 weight distribution of the car for excellent handling.

For its occupants, the open bodywork of the car represents highly practical solution for urban mobility through a turning required circle of only three meters and a footprint hardly larger than that of a scooter. The wheel provides easy and agile handling that ensures rarely getting stuck in the traffic, while the low center of gravity of this four-wheeler provide excellent stability.

A completely unique feature of this car is its octagonal wheel fairings that entirely cover the tires. This innovative design creates a pleasing and harmonious feeling along with its pearl-white and blue hub caps, where no one can see the wheel rotating any longer. Instead, the movements of the hub caps are only being seen, giving a silent and graceful gliding appearance along the road.

The Twizy Z.E. concept car is powered by a 20hp (15kW) electric motor that can develop 70Nm of torque, combining comfort with reactive performance at any engine speeds. It can accelerate like a 125cc bike and pulls away quickly from standstill. The car features a 75kph of top speed which may not seem a big number, but since it is designed to be used in busy traffic, it still is a fast car while cutting the traffic easily.

The minimalist interior features control steering pod, a mimicking game like control where brake and gas paddles embedded close to the steering wheel, offering next generation driving environment. The wheels are fully immersed with rubberized tire with independent spoke arrangement that allows the wheels to absorb the road bumps without having used the suspensions. Moreover, the out of the body wheel base has added few extra with the innovative look that the car already has with its clear body shell and green house like design.

The technology aspect of Pholeum includes a composition of memory plastic body work, allowing the material to be deformed back to its original shape under application of heat from scratches and dents. These plastic can be recycled further and remolded again into the same component if the damage is irreparable. The chassis is made of durable aluminum alloy, making the vehicle strong and lightweight. Comprehensive safety for the driver has been ensured with three external airbags, designed to deploy by sensing a fast automobile within a few meters of its radius through motion sensors. Each wheel contains quad electric motors empowered with efficient next generation hydrogen fuel cell technology.

To enrich the alternative mobility, this vehicle is empowered with an electric engine and lithium-based batteries to accumulate the energy located under the seat and charging can be done by plugging-in any standard power socket. The uniquely forward lean main body is designed against the driving direction and the precise edges and clean surfaces add up to an important impression of the design.

Although both the MMVs are light and small, they can attain a maximum altitude of around 10,000 foot above sea level. The overall size and strong structure around the riders ensures passenger safety and can be spotted easily by other vehicles in traffic. The front shock absorber, a side door protection and ballistic shaft recovery system are few safety features of these three-wheelers. Both models include air conditioning and heating, rear view video monitor, automatic vehicle leaning, dual lighting system for ground and air, and stereo MP3 input CD player.

Unlike the conventional aircraft engines, the engines of these MMVs have emission controls, therefore, motorcycle engines and transmissions are being used after modification to provide power reverse to the propellers for both the models. From the test result of the current pre-production engines, it’s been predicted that they would pass the ultra-low emission vehicle standards of California without exhaust treatment.
