The Audi urban concept – a completely new kind of concept car

  • An innovative urban concept car with 1+1 seats
  • Sleek cockpit made from CFRP, free-standing wheels with protective plates
  • Elaborate suspension, compact electric drive system for sporty performance

Audi is once again opening up new horizons: the Audi urban concept is a 1+1-seat, ultra-light car for congested urban spaces. The technical study does not fit under any of the conventional categories – the Audi urban concept combines elements of a racing car, a fun car and an urban car into one radical new concept.

The Audi urban concept is not based on any previous model – its development is solely oriented on the strict principles of lightweight construction, efficiency and reduction. The result is a concept car with no unnecessary weight, and one that concentrates on the pure essence of sporty motion.

Innovation engine: The new 1.8 TFSI

  • Ample power and minimal consumption: 125 kW (170 hp) and
  • 320 Nm (236.02 lb-ft) torque, but just 5.7 liters per 100 km (41.27 US mpg)
  • New solutions in fuel injection and other fields of technology
  • Fully electronic coolant regulation system

The engines in the updated A5 family set new standards for sportiness and efficiency. Even the base engine, the completely redesigned 1.8 TFSI, showcases the full extent of Audi’s technological competence. The engineers have developed innovative solutions in numerous fields of technology to achieve surprisingly strong performance with minimal fuel consumption.

The high-end four-cylinder engine displaces 1,798 cm3 and delivers a brawny and constant 320 Nm (236.02 lb-ft) to the crankshaft between 1,400 and 3,700 rpm. Peak output of 125 kW (170 hp) is achieved at 3,800 rpm. With a manual transmission, the 1.8 TFSI accelerates the Audi A5 Coupé from zero to 100 km/h (62.14 mph) in 7.9 seconds on its way to a top speed of 230 km/h (142.92 mph). Despite all this power, it consumes just 5.7 liters of fuel per 100 km (41.27 US mpg) on average, which corresponds to best-in-segment emissions of 134 grams of CO2/km (215.65 g/mile). Consumption has been reduced by 21 percent compared with the previous model engine.

Johan Ernst Nilson – North Pole to South Pole With Audi

  • Audi is partnering Johan Ernst Nilson for his “Last Great Adventure – Pole2Pole”
  • Expedition equipment tested in the Audi Wind Tunnel
  • Audi engineers help to develop super-lightweight sled

It is his greatest adventure to date and probably one of the greatest worldwide. Today, Johan Ernst Nilson starts out on his Pole2Pole expedition. Within the space of 12 months he intends to travel from the North Pole to the South Pole, using carbon-neutral transportation all the way, powered only by nature – and himself. In order to decide which equipment was the best possible choice he was able to rely on Audi technology and know-how for assistance: Nilson tested his equipment under extreme conditions in the Audi Wind Tunnel and Cold Chamber in Ingolstadt. Moreover, Audi engineers were part of the team that developed his super-lightweight sled.

Vorsprung durch Technik: Research for the Future

Audi AG has posted an inside look at the testing involved with developing new vehicles. Audi Engineers put an immeasurable amount of time into each vehicles development cycle perfecting the things we take for granted. Most of these technologies will probably go unnoticed to most drivers and passengers but they are there protecting them from the worst case scenarios.

Test at the reference automotive electronics systems are used to an Audi through its paces to test. Employees of the Electronics Center analyze the functional effects of electrical system voltage fluctuations.

Audi: Next-Generation A4, Q7: Aluminum-Intensive

  • Next-generation Q7 will be as much as 880 pounds lighter.
  • Using 18 different aluminum alloys in the A8, some of which it formulated itself, and that strategy will continue
  • New A4 design has saved 100 kilograms, or 220 pounds

Part 4: Audi TechDay: Lightweight Design: its use in the future

The idea foundry – the Audi Lightweight Design Center
To expand your lead, you have to continuously come up with new solutions. With this in mind, Audi established its own Aluminum Center for Development, Production Planning and Quality Assurance at the Neckarsulm site in 1994.  The facility was renamed the Aluminum and Lightweight Design Center (ALDC) in 2003. Since 2009, it has gone by the name Audi Lightweight Design Center, retaining the same abbreviation.

The ALDC is an idea foundry for the company, its spearhead in the field of lightweight construction. The roughly 180 specialists in Neckarsulm investigate all of the key topics of the future – materials and their alloys, machining and shaping technologies, methods and processes. The ALDC lays down the foundation for the bodies of the future and also for the methods required for their production.

Part 3: Audi TechDay: Lightweight Design: its use in production

Inspired by nature – the ASF bodies
Audi has a tremendous source of inspiration for lightweight construction: nature. Nature wastes nothing, using only as much material as needed in exactly the right place to achieve the best result. Audi follows bionic principles in many areas of ASF technology, both on individual parts and on the overall design of the body.

Aluminum is an excellent material for vehicle bodies. With its low density of 2.7 grams per cubic centimeter (0.098 lb per cu in), it is roughly two-thirds lighter than conventional grades of steel, and since it is a relatively soft metal, it is easy to machine. Alloys, the most important components of which are magnesium and silicon, provide the high strength necessary for vehicle bodies.

Part 2: Audi TechDay: Lightweight Design: Milestones – historic and current models

Lightweight construction with continuity: Audi milestones
Lightweight construction has long been a driving force at Audi. Development work on the ASF body began back in the early 1980s. Audi has been building cars with aluminum bodies since 1994 – with a high degree of continuity, in contrast to its competitors.

Audi Sport quattro (1984)
The Sport quattro is a brand icon. Beginning in 1984, Audi built 214 units by hand in order to homologize its new competition car for the Rally World Championship. The five-cylinder turbo, which displaced just 2.1 liters, produced 225 kW (306 hp) in the street version, making it one of a small group of extreme sports cars at the time.

The Sport quattro had a wheelbase that was 32 centimeters (1.05 ft) shorter than that of the model on which it was based, the Ur-quattro (original quattro). 4.16 meters (13.65 ft) long, it weighed just 1,300 kilograms (2,866.01 lb) thanks to extreme lightweight construction. Only the bodyshell and the doors of the “Shorty,” the latter taken from the Audi 80, were made of steel sheet. The rear hatch was made of a polyester material.

Part 1: Audi TechDay: Lightweight Design – A core competence of Audi

Vorsprung Durch Technik — It’s the heart and soul of Audi design. This is part one of a four part brief composed by Audi.  It documents their progressive work using weight saving technologies to build a better automotive future. Audi continues to make strides in the use of aluminum in all of their past, present and future designs. The extensive use of aluminum will allow for strong, lighter and more fuel efficient vehicles. It’s not a new thing for Audi and theses briefs provide the history and details to prove it. — Ed.

TechDay Lightweight Design

Lightweight construction has long been a top priority at Audi; it is one of the pillars of the brand. As the pioneer of the self-supporting aluminum body, Audi is the worldwide leader in the field of lightweight construction. Future innovations will ensure that the brand can continue to reverse the weight spiral. Each new Audi model will be lighter than the one it replaces.
