Audi A3 Concept: The future of the Four Rings

After publishing a few days ago, the first sketches, at the Geneva Motor Show Audi unveils the Audi A3 Concept notchback sedan 4.44 meters long, 1.84 wide and 1.39 meters high only one car that incorporates all technical and stylistic trends of the future House of the Four rings. The clean design and rational represents yet another evolution of the Audi design language with the single-frame grille that dominates the front giving it a sporty sculptured look.

Its structure is made from a material made of carbon fiber reinforced plastic (CFRP), the aluminum frame from three-dimensional shape creates a visual effect that emphasizes the breadth of the show car. The angular shape and sharp projectors are equipped with LED technology and blend with the rounded corners of the grille, forming a passage that marks the starting point of the ribs of the hood.

The side, featuring a very high waist line, it gives muscular and taut surfaces that are joined in harmony with the sloping rear window very reminiscent of the forms of a coupe. A fundamental part of the scenic effect is given by the car wheel shaped accentuated that express power, at the same time giving the impression that the car is glued to the ground.

The exterior mirrors, aluminum and carbon fiber, reminiscent of a sports car, while the door handles have brushed aluminum caps, recessed flush with the goalkeeper. The sculpted lines of the car are also taken from the queue that culminates with a sleek spoiler, while the bottom is the fan also made of CFRP material and incorporating the two discharges from a square shape.

The practicality of the third volume also provides a load capacity equal to 410 liters and lowered the threshold load baggage storage facility operations. The austere and elegant interior is built around the new bridge with horizontal. The center console - separate from the main tunnel - is characterized by a minimalist design that recalls some of the concepts seen on the small Audi A1.

Above the console was placed a large 8-inch retractable screen where you can see the many multimedia features of the car, such as satellite navigation and audio controls, in addition to numerous adjustments sophisticated MMI. Rear passengers enjoy the same attention as the front seats: the couch is shaped to accommodate and "contain" two great people who can use the two-tablet PC touch screen installed in the front seat backs.

The UMTS connection provides Internet access for all passengers which can easily browse, send e-mail and use any kind of multimedia application at any time. The aggressive appearance of the car reveals the potential of the engine that is flying under the hood. The unit used for this concept is in fact a powerful 2.5-liter 5-cylinder turbocharged and equipped with gasoline direct injection (FSI), capable of delivering well 408 hp and 500 Nm of torque, available over a range of schemes that between 1,600 to 5,300 rpm.

These performances by the House left no doubt about the potential of the car: the A3 Concept burning sprint from 0 to 100 km / h in 4.1 seconds and reaches a top speed of 250 km / h, electronically limited to tradition Audi. Consumption have declared a value of only 9.1 liters of fuel burned 100 km, resulting in emissions of 212 g / km of CO2 emitted into the air.

These interesting figures were obtained by using an oil pump control, and Audi to the thermal management system combined with energy recovery device. Power is managed by the S-tronic transmission with 7-speed action from two clutches. The gear changes follow each other with lightning-grafts, no cracks, never report loss of power.

The driver according to the needs of the moment can select one of 5 modes of travel: comfort, auto, dynamic, individual and efficiency, the last of which ensures economic operation of the engine. The change can be used in either automatic or manual, in the latter case the gears are selected using the paddle positioned on the steering wheel also features the "launch control" allows very fast standing start, avoiding smoking stage of the huge tires.

The power is discharged on the permanent four wheel drive "four" characterized by an electronically controlled multi-plate clutch. In the case of a slip of the two axes, a few moments in the clutch transfers torque to the wheels with better grip. The structure of the A3 concept follows the pattern of the sporty RS 3 Sportback, designed to trace the curves quickly, but more stable and predictable, in fact the behavior is always neutral self-steering of the car almost to the limit.

The front suspension exploit a classic McPherson layout with support and split axle features a track width of 1,572 mm, while the components of the structure exploiting a special aluminum alloy. To the rear axle was used a four-arm made of high strength steel, can absorb longitudinal and lateral pressure.

The track width of 1,542 mm, is home to shock absorbers and coil springs are mounted separately. For the braking system was chosen to fit pize front discs with four piston supported by a stability system (ESP) that can be set in sport mode or switched off completely. The braking system is housed in specific tires measuring 245/30 and are mounted on alloy wheels double-spoke 20-inch, designed to enhance the ventilation of the brakes.
