Audi Urban

Concept

"How much car is necessary to deliver driving pleasure and urban mobility in an entirely new way?" This question was the starting point for the Audi urban concept. A model of a sailplane was in the studio during the development process as an example of lightweight construction, efficiency and reduction - of the principle of "less is more."

The result is a vehicle that cannot be pigeonholed, a vehicle that redefines the term "driving pleasure" and is completely unencumbered by the baggage of conventional concepts. The Audi urban concept concentrates on the pure essence of driving and conveys freedom at the premium level. At the same time, it offers the comfort and safety of a closed automobile, making it far superior to any motor scooter. With its sleek body and free-standing wheels, the technology study is progressive and highly dramatic while at the same time extremely sporty, yet surprisingly comfortable.

The cabin of the Audi urban concept offers slightly offset seating for two. The roof slides back for entry. This innovative solution makes the Audi urban concept even more fun to drive because the canopy can remain open in good weather. It also allows the cabin to be aired out very quickly. The fit and finish of the show car is characterized by the obligatory Audi perfection. The car's technology is reflective of the brand's wide-ranging competence, particularly in ultra-lightweight construction.

The brand with the four rings has created an entirely new class of vehicle with the Audi urban concept, and that on the premium level. It also marks the new entry point to Audi's future range of electric vehicles, which is crowned by the R8 e-tron high-performance sports car. The Audi urban concept quite literally makes it easy to get into electric mobility.

The technology study is targeted toward people who are interested in technology and are enthusiastic about new approaches to mobility, independent of their age and status. In particular, it addresses an urban public whose lifestyle both reflects the car's modern concept and the driving pleasure associated with it and is a good fit for a possible innovative leasing system.

Technology

The Audi urban concept is also without peer with respect to the technical concept. The outer skin of the show car is made of carbon fiber-reinforced polymer (CFRP); the occupant cell is a mix of CFRP monocoque and an aluminum structure. This ultra-lightweight construction is the foundation for the technology study's extremely low curb weight of just 480 kilograms (1,058.22 lb).

The sophisticated chassis underscores the distinctively sporty personality of the Audi urban concept. Wishbones made from a combination of aluminum and CFRP locate the free-standing, 21-inch wheels.

Manufactured using cladding technology, the wheels are very light and feature a variant of the blade design from the Audi e-tron models. The tire sizes are as unusual as the car as a whole - 125/60 up front and 145/50 in the rear.

The Audi urban concept uses pushrod technology borrowed from motorsports. As in a racecar, the struts mounted in the interior of the monocoque are nearly horizontal. Four disc brakes provide the stopping power. The turning circle measures less than nine meters (29.53 ft) - ideal for a city car. Thanks to the vehicle's low weight, the rack-and-pinion steering does not require any power assistance. Crumple zones in the front and rear plus two airbags provide for a high degree of passive safety. An innovative assistance system helps the driver to avoid collisions with pedestrians.

The battery is mounted transversely behind the seats. The lithium-ion battery, which weighs around 90 kilograms (198.42 lb), stores 7.1 kWh of usable energy. The study's two electric motors together produce 15 kW (20 hp) of continuous power and 47 Nm (34.67 lb-ft) of torque. The motors are mounted between the rear wheels, which they drive via a single-speed transmission.

The Audi urban concept accelerates from 0 to 100 km/h (62.14 mph) in 16.9 seconds. It reaches 60 km/h (37.28 mph) in around six seconds. The show car steps off from traffic lights smartly thanks to the torque of the electric motors, which is fully available from standstill. Top speed is governed at 100 km/h (62.14 mph).

The action radius in the European driving cycle is 73 km (45.36 miles). The battery recharges completely in about 20 minutes with 400 volt three-phase current, and in approximately one hour with 230 volt household current.
