The first and second generation of the Audi A3 rolled off the assembly line with an analogue speedometer and tachometer. The current A3 is available with the optional Audi virtual cockpit. The all-digital cockpit depicts the most important driving-relevant information in high resolution on a TFT screen with a 12.3-inch diagonal. The driver can switch between two views by pressing the 'View' button on the multifunction steering wheel. In Classic mode, the instruments are as large as conventional analogue instruments. In Infotainment mode, however, a central window dominates. It provides more space for the navigation map or displays easy-to-read lists from the Telephone, Radio and Audio functions. Tachometer and speedometer are displayed here as small round gauges.
Cockpit: from analogue to digital
The A3 is also the forerunner in the Audi model portfolio when it comes to drive system variants. Besides eight conventional petrol and diesel engines, the A3 model series has also been available in the UK with two alternative drive systems since the launch of the third generation: a natural gas-powered model available and a plug-in hybrid. The Audi A3 e-tron is the premium brand's first plug-in hybrid, pairing a 1.4 TFSI with an electric motor. The combustion engine produces 150PS and delivers 250 Nm (184.4 lb-ft) of torque; these figures for the electric motor are 75 kW and 330 Nm (243.4 lb-ft), resulting in overall system power of 204PS. When connected to a 380 volt three-phase outlet, it takes just over two hours to fully recharge the lithium-ion battery (8.8 kWh).
Drive system: from conventional to alternative
The racing-inspired electrohydraulic dual-clutch transmission made its debut in an Audi series production model with the second-generation A3. It enabled lightning-fast gear changes with no break in propulsive power. Today the S tronic dual-clutch transmission is firmly established and is available in nearly every model family.
Transmission: first dual-clutch automatic transmission
The A3 reflects the development of lighting technology over the last 20 years. The first Audi A3 was equipped with halogen lights. Today the premium compact comes standard with xenon headlights. Optional Matrix LED headlights illuminate the road with a light very similar to daylight without causing glare for other road users. 15 LEDs in each Matrix LED headlight radiate from three reflectors to produce the high beam. A camera on the interior mirror feeds information to the controller. The controller turns individual LEDs on or off as needed, or dims them in 64 steps. The Matrix LED headlights can thus realise several million different light distributions. They specifically illuminate road signs with 30 percent less power to prevent glare caused by reflections.
Light: from halogen to Matrix LED
The numerous driver assistance systems in the A3 exemplify the premium brand's rapid pace of development in electrical systems and electronics. The current model generation offers such systems as Audi active lane assist or Audi pre sense front including predictive pedestrian protection. The optional traffic jam assist in the current A3 is groundbreaking. The system maintains distance to the vehicle ahead in traffic. If the customer combines the traffic jam assist and S tronic, the A3 automatically sets off again following brief stops. In slow-moving traffic up to 37mph on well-paved roads, the traffic jam assist even takes over the steering – a key step toward piloted driving.
Assistance systems: on the home stretch to piloted driving
The Audi A3 has now become a global player, having conquered the roads of more than 100 sales markets. Audi produces the Audi A3, A3 Sportback, A3 Sportback e-tron and A3 Sportback g-tron* models at its site in Ingolstadt. In 2001, the Audi Group expanded portions of A3 production with a facility in Győr, Hungary. Today, the Audi A3 Saloon and A3 Cabriolet come off the assembly line there. Audi produces the A3 Sportback and the A3 Saloon for the Chinese market at its factory in Foshan. Total production volume since the car made its debut 20 years ago is more than four million A3 models.
