Audi urban concept, an urban vehicle with a 1 +1 seating. Although it has four wheels, the electric propulsion showcar not fit into any existing automotive category. The urban concept Audi weighs only 480 kg and combines elements of a racing car, a roadster, a recreational vehicle (fun car) and a city car, giving life to a radically innovative new concept. No doubt has the potential to rise as the pioneer of a new mobility.
“How many cars does it take to create a completely new way of driving pleasure and urban mobility?” This is the question that has given rise to urban Audi concept. The study design was presided over every phase of development by the model of a glider, a symbol of light construction, and reduced efficiency, ie the principle “less is more.”
The result is a vehicle that has no place in any current stereotypes, a vehicle that gives new meaning to the term “driving pleasure” and is completely free of any hindrance. The Audi urban concept focuses on the pure essence of driving, conveying release level. However, it also offers the comfort and safety of a closed car, making it far superior to any scooter. The technical prototype, with its slender body and wheels of the same independent, modern and very emotional, but also distinctly sporty and surprisingly comfortable.
In the cockpit of the Audi urban concept fit two people, while the passenger seat moved back slightly compared to the driver. The roof can be opened by sliding backwards, presents a novel solution that, on the one hand, increase driving pleasure, as the dome can remain open during good weather, and secondly allows very rapid ventilation.
Showcase finish boasts a perfection that is already an obligation Audi. And their technology reflects all brand competition, particularly in regard to lightweight construction.
With the urban concept Audi brand with the four rings opens a completely new vehicle segment and category Premium. At the same time Audi completes its range of electric vehicles for the future, which now covers urban concept from Audi to the R8 high-performance sports e-tron. This vehicle literally provides access to electric mobility.
The technical prototype is aimed at those interested in technology and new ways of mobility, no matter their age or status. And especially to the urban public whose lifestyle fits the modern concept and driving pleasure it brings, as well as a possible system of leasing of the most innovative.
The urban design concept Audi is completely new, but has historical roots you determine which date back to the Auto Union racing cars of the 30’s. These race cars are already ahead of its time for its concept of lightweight construction and engines mounted on the back. His big-wheel independent, outside body, are another area that shares the urban Audi concept with them.
The technical prototype electric White color pearl effect us today measures 3219 mm long, 1678 mm wide, but only 1189 mm high, and his body all the lines pushed forward. All glass is extremely flat, the roof line slides down a wedge side window while drawing a line upward. The typical Audi waistline enhances this part of the body of the urban concept.
The blade upright and leaning forward is in front of the rear wheel stresses the lateral perspective. The red outline acts as a bow speed and remember to roll high-performance sports Audi R8. At the bottom, the sides of the body is wider.
This increases the soil surface, which has two important functions: firstly generates downforce at high speeds, and on the other hand can be used for battery charging by induction, a process especially convenient.
The typical single-frame grille Audi bearing the four rings, is presented in the urban Audi concept as a closed surface can be folded forward, as she hides behind the load connection. Flat LED headlights protrude from the body by adopting a three-dimensional effect.
Fiber bands that make up the flashing LED extend protective plates on the wheels. The fairing surrounds the wheels almost completely separated from the body, and the front wheel rotates with the wheel turning. The rear lights, three-dimensional design taillight and brake are built into the vehicle body and line the top of the rear window. The rear of the car features a small trunk that opens like a drawer.
Another innovative idea from Audi exclusive urban concept is the mobile nature of the front segment of the glass area, which is mounted on rails and can be moved back by hand, sliding the rear segment rigid.
During the march the roof can be opened or closed as desired. The roadster is a technical prototype adapted to the needs: it has no windows that go down nor a heavy air conditioning, and the dome closed against rain and cold air. As an alternative to urban concept with a sliding roof Audi has developed a second body version, a spyder with a flat strip surround glass doors that open obliquely upward.
The entrance to the urban concept Audi is done with the roof moved backwards. Both driver and passenger must go to the car avoiding the edge, as in a bathtub, because there are no doors. However, it requires great flexibility, since a grip on the windshield frame and specially designed seating surfaces provide access to the vehicle.
The Showcase offers space for two people. The driver and passenger sit side by side, but the right seat is moved back 30 cm to provide enough space for shoulders and arms. The two bases of the seats are part of the monocoque, thus saving considerable weight. They feature a padded foam material tailored to customer, like a racing car. Seat belts pass through an opening in the backs.
The feeling you have when riding in the urban Audi concept slightly resembling an airplane cockpit and the seating position is very sporty. The driver can adjust the position of the steering column and pedals, made of aluminum. Both components can be moved lengthwise, pedals 22 cm and 14 cm steering column to access additional vehicle and 6 cm for individual adjustment.
The steering column is exposed, and consists of a strong open profile in the center of elegant design that is mounted nearly horizontally. On the back features a display which shows the most important information. The steering wheel, small hexagonal keys and integrates with wheels that can also handle driving programs of electric propulsion system offers Audi drive select system.
Everything inside the technical prototype has undergone the strict dictates of lightweight construction. Below runs a sturdy windshield wing-shaped profile, also open in the center, facing the interior of one side to another, as new dashboard court, integrates a control unit for heating and two large diffuser air.
Instead of a carpet pad is used to cover new parts of the floor, made of a technical fabric originally developed in the athletic footwear industry that repels water and is very sturdy. The seats are upholstered with fabric and foam padding edges are trimmed with kangaroo leather. The dashboard is decorated with aluminum inserts.
In regard to the technical concept, the Audi urban concept is also unique in its kind. The outer skin is manufactured Showcase plastic material reinforced with carbon fiber (CFRP), while the monocoque cabin combines a CFRP and aluminum structure. This lightweight construction provides the basis for the extremely low unladen weight of the technical prototype, a mere 480 kg.
The complex undercarriage markedly enhances the sporty Audi urban concept. As independent wheel suspension 21-inch triangular wishbones compounds act by a combination of aluminum and CFRP. For the manufacture of the wheels, which are very light, used a technology called cladding, and its design differs slightly from the image and produce laminar Audi e-tron. The format of the tires is as unusual as the car itself: 125/60 front and 145/50 rear.
The urban concept Audi makes use of push rod from the world of racing, and like the racing cars, his arms telescope, located inside the monocoque, are in a near horizontal position. Four disc brakes are responsible for deceleration. The turning diameter is less than 9 m, making it ideal for a city car. With the reduced weight of the vehicle, the steering rack can do without the power assistance. Deformation zones in front and behind, and two airbags, ensure high passive safety. A novel assistance system helps drivers avoid collisions with pedestrians.
The battery is mounted transversely behind the seats. The lithium ion battery, weighing about 90 kg, 7.1 kWh of energy stored, of which 5.7 kWh useful. The two electric motors together yield prototype 20 hp (15 kW) of continuous power and 47 Nm of torque, and are located between the rear wheels, which propel through a single gear ratio.
The urban concept Audi accelerates from 0 to 100 km / h in 16.9 seconds, and reaches 60 km / h after about 6 seconds. With the pair of electric motors, available now at a standstill, the showcar accelerates the output of a light in a very dynamic. Its top speed is limited to 100 km / h.
Autonomy in the European test cycle is 73 km and the battery was fully recharged in about 20 minutes when 400 volts alternating current, and in about an hour in the home network of 230 volts.
Audi is working intensively in the future of charging technology to offer an alternative to vehicle load plugged into the outlet. Wireless Charging Audi concept (AWC) refers to non-contact charging by induction. The facility needed for the load, which is a plate composed of a coil and converter AC / CA, is placed in the regular parking Audi urban concept and is connected to the mains. The primary coil, inserted into the plate, generated with 3.6 KW of power a high frequency alternating field.
When the urban concept is placed on the plate, the charging process starts automatically, the alternating magnetic field of the facility through the gap induces an alternating electrical current to the secondary coil, which is integrated into the vehicle. After rectification of this current is fed to the onboard network, which charges the battery or fuel as heating equipment. The alternating field is set only when a vehicle on the surface, so that there is a danger to people or animals.
The charging process ends automatically when the battery is fully charged, although the driver can stop at any time. The effectiveness of the AWC is comparable to other charging technologies. Rain, ice or snow will not affect you. The new technology makes charging of electric vehicles is simple and incredibly comfortable. In a next phase of development may also be integrated into road infrastructure, for example in car parks or residential streets.
