Flat, wide and compact: the three hallmark design characteristics of the Audi A3 Sedan. Even the vehicle proportions accentuate the dynamic character of these new models. While the Audi idiom of sporty elegance embodies the basic traits of the design, a wealth of other design details on the Saloon also make a thoroughly distinctive statement. Muscular taut surfaces, coupé-like roof contour and especially the wedge-shaped design lines and shadow edges instantly emphasise the vehicles’ pronounced forward-moving stance.

Hybrid aluminium construction:
Unlike many other vehicles in its class, the Audi A3 sedan is not built simply of steel, but using hybrid aluminium construction. An innovative lightweight construction technology that has hitherto been used mainly for sports cars – and produces lower consumption, superior agility and therefore greater efficiency.
TFSI® engine:
FSI® direct-injection technology is a unique Audi innovation that was originally developed for the Le Mans 24-hour endurance race to deliver more power and torque, as well as enhanced fuel efficiency. Precisely the right amount of fuel and air are injected into the combustion chambers, enabling the engine to ‘breathe’ more easily. It results in reduced heat loss and increased output, with around a 15% reduction in fuel consumption and significantly lower exhaust emissions. We’ve also developed TFSI®, with turbocharging – giving cars an extra injection of power.
TDI® engine:
We introduced TDI® to the roads in 1989, and since
then, we’ve continuously refined it, including developing common-rail technology. Under this system, a series of piezo injectors uses electrical charge to precisely control the amount of fuel injected into the engine. As well as reducing noise, this allows combustion to happen at a lower temperature, with less oxygen, which lowers emissions.
S tronic® Transmission:
Driving is all about thinking ahead, which is just what the S tronic® dual-clutch transmission does. It works almost as two separate systems, one engaging the odd-numbered and the other the even-numbered gears. So when you’re accelerating in second, it has third gear waiting for you. And once you make the switch, it’s already thinking about fourth. With two clutches working together, you can change gears almost instantly while experiencing smooth, uninterrupted power.
Energy Recuperation:
When a vehicle brakes, the discs convert the kinetic
energy into thermal energy, which is wasted as it cannot be used. With a recuperation system, like the one that is fitted as standard on all A3 models, the kinetic energy is converted into useful electrical energy. The way it works is simple. While the car is coasting or braking, the alternator voltage is raised above the level of the basic electrical system, which enables the alternator to generate electrical energy and store it temporarily in the battery. When the vehicle accelerates, this energy is used to relieve the load on the alternator, resulting in a fuel saving of up to 3%.
Aerodynamics:
A car’s shape is one of the most important factors
that influences its e ciency. It’s why we’ve worked to make the Audi A3 as aerodynamic as possible.
