2009 Audi Sportback Concept

2009 Audi Sportback Concept

Audi has unveiled Audi Sportback concept car show in 2009 North American International Automobile Show. In systematic refinement characteristic brand design elements, the five-door model offers a look at the future of Audi Design vocabulary. Since pronounced coupe-like silhouette and the large rear hatch, a length of 4.95 meters (16.24 feet), 1.93 meters (6.33 feet) and only 1.40 meters tall (4.59 feet) of the vehicle safely advanced to the luxury class.Technology Audi Sportback concept noticeably futuristic. Food is provided in the world of clean diesel technology: 3.0-liter V6 TDI clean diesel fuel almost completely eliminates the nitrogen oxides. This engine is already the emissions from all 50 U.S. states and EU6 standard is planned in force in 2014. And a number of measures to ensure the efficiency rating means that the Audi Sportback concept is expected to achieve an impressive fuel consumption figures for the 5.9 liters of diesel per 100 km (39.87 U.S. MPG).

Driving dynamics in a new guise - the idea

Since its introduction in 2004, the concept Sportback has established itself in the compact class. The success of Audi A3 Sportback exceeded even the expectations of their bodies - a lot more customers choose the four-door model with a large rear hatch, the three-door sister.But it is much more than the two extra doors, which are set by Audi A3 Sportback, in addition to the basic model. It is characterized by elegant sports coupe, versatile five-door model, modern technology and a clear sportiness - the dynamics of driving in a new guise.It also offers more space and variability thanks to the tail end of which a total of 54 millimeters (2.13 in), which is more in the three-door model.Starting the first production Sportback marked the second time that Audi start a new trend in the automotive market. The development of the first models in the Avant-seventies laid the foundation for a new class of vehicles far beyond the question of the usefulness of the classic station wagon. A notable selection futuristic and dynamic design, high quality equipment and extreme volatility were the distinctive features of each Audi Avant from the outset.Audi Sportback concept show car is now rolling to the start line with a dual mission: It had been suggested by the title, it symbolizes Sportback principle in its pure form, combined elegance, sportiness and variability.It also signals the company car to show determination not to limit the Sportback version of the compact segment. As indicated earlier in the Audi A1 Sportback concept - a star in 2008 Paris Motor Show - The brand with the four rings will sharply increase the number Sportback models on the market.

Design

Design Audi Sportback concept is almost monolithic clarity and reduce the huge number of lines. The roof, the shoulder and the sill line, appeared to have been made with a single blow. Window strip coupe with four doors frameless kept strictly flat. Viewed from the outside, gently contoured wheel wells over a 10-spoke 21-inch wheels enhance the impression accurately determine the body surface.One of the features are familiar with the two-door coupe Audi A5 more boldly accentuated here: markedly horizontal shoulder area stresses targeting the vehicle body on the road. This effect is further strengthened in front of and behind the broad, flat LED light units. The form is almost fragile promising side mirror is upturned tips - "winglets" - modern jet wings.Show car also offers a new interpretation of a single frame grille. The decision not to use the vertical pillars and a low overall height of major proportions to emphasize sports front of the vehicle. Moreover, particularly striking is the changes of the external circuit one frame grille, as well as posted on the A1 Sportback show car. Flattened the top of the bottom of the visual center of gravity and provide a vivid look at the front edge.Aerodynamically designed air intakes under the headlights to function as air deflectors, which determine the required cooling air duct at reception. They stylistic effect of strengthening the impression of width.Tail show car also apparently linked to the coupe A5. High upper edge of the rear hatch, it is surprising clearly below the surface of the rear lights.The low level of separation of edges and horizontal lines - another feature - the width of stress, and therefore the nature of sports Audi Sportback concept. The four tailpipes integrated into the body and reflector air diffuser insert tips are taken from the sports car sector.Interior design is a procedure and a purist but elegant at the same time. A large glass roof underlines the breadth and sense of space. In the driver-oriented cockpit, air vents, instrument cluster and the retracting MMI monitor contained in the aluminum filigree border.As was the case with the foreign, interior is characterized by an emphasis on horizontal lines and large surfaces. A particularly wide center console - extends from the dashboard to the back - seems to be merely an expression functions.Flat display system is realized as the retractable MMI system in the show car. When the ignition is activated, it spreads horizontally from the slot over the central air register before moving into an elegant arc in the vertical, comfortable position.High-quality materials and construction of fit and finish are obvious when looking around the interior of Audi Sportback concept, and when referring to the surface. Interior decoration is almost entirely made of leather: from headlining, dashboard, doors and all the upholstery seats all the way up to the trunk, with leather stitching emphasizing vehicle design language. Large strips of wood trim on the dashboard, center console and doors are made of oak blockboard and sports delicate horizontal patterns of light and dark lines.Since its surface piano lacquer and brushed aluminum, MMI control unit also adds to the exclusivity of the exclusive interior. Attention to detail even extends to the door opener: Its form is almost a perfect reflection of the distinctive lines of the small rear side windows - the provision of internal and external formal unity.Four sports seats to wait for the driver and passengers. Diamond-stitching of the skin resembles the classical tradition of GT. The shoulders, head and legs like premium-class touring car. With volume of 500 liters (17.66 cubic feet) a barrel generously sized and appointed with high-quality materials.

Drivetrain

The developers at Audi has chosen the world of clean diesel technology as a unit consistent with the best Audi Sportback concept show car. Six-cylinder 3.0 TDI clean diesel is equipped with a system to effectively reduce emissions of nitrogen oxides. Diesel engine Audi development engineers have joined the entire range of new measures in this latest TDI generation: Piezo Common Rail system with 2000 bar injection pressure, high exhaust gas recirculation system and optimized turbocharging result in significantly reduced emissions of the engine material. One of the most important is the sensor of a combustion chamber, allowing more precise regulation of the processes of combustion in the engine - this is the first time that such sensors have been installed on any machine in the world, marking yet another Audi innovation.The state's new-generation TDI as the definitive clean-running, high-tech diesel is sealed by down the exhaust emission control system that reduces emissions by up to 90 percent. This system uses AdBlue, biodegradable, water, an additive that is introduced in small quantities above DeNOx catalytic converter. In addition to the catalytic converter, exhaust emission control system consists of measurement modules, AdBlue tank and heated lines, as well as a developed system of sensors. Additional oxidizing catalytic converters and highly regulated diesel particulate filter round comprehensive emission control system.Due to its extremely low emissions, these modern direct injection diesel engines can be put into operation anywhere in the world, even in the U.S. state of California, which has the most stringent emission limits. Compared with the fleet average of gasoline engines, usually in the U.S., TDI boasts fuel efficiency of the use of up to 40 percent. Diesel technology, thus making a greater contribution than any other type of engine, to reduce consumption of fossil fuels. Audi offers this car in the U.S. and Europe beginning in 2009.As in the American version of Audi Q7 3.0 TDI, V6 produces 165 kW (225 hp) and 550 Nm (405.66 lb ft) of torque at Audi Sportback concept. Power is transferred to the wheels via Audi most advanced transmissions: the new 7-speed Tiptronic. Quattro permanent all-wheel-drive system ensures that the torque generated by a powerful TDI is also effectively converted to the movement and dynamism in all conditions.Weighing just 1800 kilograms (3,968.32 pounds) and the drag coefficient of 0.30, coupe will accelerate from 0 - 100 km / h (62.14 miles / h) in less than seven seconds and reach a maximum speed of 245 km / h (152.24 miles / h).Audi Sportback concept of average fuel economy in accordance with European standard ECE only 5.9 liters of diesel per 100 km (39.87 U.S. MPG), and its CO2 emissions less than 156 g / km (251.06 g / km). These figures are sensationally low for large models is achieved through extensive performance optimization measures.For example, the model electromechanical power steering consumes energy only when steering is included, but not while driving in a straight line.TDI engine is equipped with an innovative system temperature. When the engine is warming up, part of the coolant flow is diverted - another way to improve efficiency, because it helps the engine to warm up quickly. This is a significant operational savings, as many travel relatively short. Fuel pump also works only when there is a demand for fuel, and therefore uses less energy.7-speed S Tronic transmission is very efficient unit with a wide spread of gear ratios. For the first time he had been fitted with transmission oil heating systems, so that it reaches its operating temperature much earlier than intended and, therefore, has a lower level of internal friction.When coasting, Audi Sportback concept - like the Audi A4 and Audi Q5 production models - recuperates energy. This increases the power of current and used to charge batteries. This energy, which is actually for free repair, fed back into the electricity transmission system when necessary. Automatic start-stop system TDI engine shuts down to conserve energy, for example, waiting for traffic signals.And when it is on the move, tires are optimized for low resistance roll to reduce fuel consumption significantly without incurring any shortcomings in the performance area.

Driving dynamics

Audi Sportback concept show car takes the basic architecture, and many of its suspension components with the brand last and most successful model of the family: a dynamic model A4/A5 series. The dynamic suspension set standards here as well, combining precision and dynamism with a high stability and the Chief of poise. Brackets suspension, steering, wheels and brakes were designed for maximum performance and numerous aluminum components are used to keep unsprung weight to a minimum.Five new lines of the front suspension makes a significant contribution to the dynamic nature of the car. By moving further and further differential adhesion, engineers were able to re-design the front axle 154 mm (6.06 inches) forward. The result is an optimal weight distribution between the front and rear axles.Front suspension consists of five links per wheel - to communicate and control arm at the bottom, and two arms control at the top. The fifth link - track rod - joins the steering box and axle bearings. All these references are made from forged aluminum, providing a low unsprung mass, ultra-precise wheel control and a high level of security disaster. Anti-roll bar fabricated with high strength tubular saves additional weight. The basis of the rear axle is a subframe of high bending and torsional stiffness.If the sports-processing is to be combined with a high level of ride comfort, unsprung mass should be the lowest possible level. Audi holds that approach for all the rear axle components. The upper control arms and track rods are of forged aluminum. Provides high rigidity and finger flexion angles change very little when dynamic forces act on the wheel.CDC (continuous damping control) shock absorbers, similar to those that Audi already uses on the luxury Q7 SUV with air suspension, a tube, gas-filled hydraulic units with additional external valve and connecting pipe. Their operation can be continuously varied.Electromagnetically voltage proportional to the valve regulates the flow of hydraulic fluid between the inner and outer tube damper. Less than a flow cross-section of damping characteristics of a solid, more than one makes softer.The control unit applies adaptive operating characteristics when the driver has chosen via Audi drive select. It adapts to match the driver's driving style and road conditions. Even with the comfort mode, shock absorbers can be switched on in a moment to establish a firm, if desired, although not an absolute limit. They are installed in conjunction with sports suspension springs, which still provide a high level of ride comfort, even off-road use.The control unit selects the optimum damping force for the current driving situation, for example, the firm damping to prevent body roll and pitch when cornering fast or braking, lower damping force, or where the surface under the wheels of difficult and uneven.Show vehicle for the first time Audi used electromechanical steering in a car with a longitudinal engine. Its main advantage is that, unlike conventional systems, power steering, it only consumes power when in fact the steering. On average, which means fuel economy 0.2 liters per 100 kilometers, depending on driving conditions.Electromechanical Management Audi Sportback concept can also communicate with the leadership of parking assistant for fully automatic steering when parallel parking.Audi Sportback concept is equipped with ceramic brakes on all four wheels for effective deceleration even under the most demanding conditions. Compared with conventional steel discs, ceramic brakes not only in the last four times longer, up to 300,000 kilometers (186,411 miles), and also offer high resistance disappears. A significant reduction in weight also leads to benefits in terms of comfort and handling, thanks to reduced unsprung mass.The front axle 380 millimeters (14.96 inches) ceramic discs installed in combination with 21-inch wheels. The rear discs have a diameter of 356 mm (14.02 inches). Elaborate cooling geometry ventilated brake discs ensure optimum cooling of the brake discs. The firm grip on the brake disc is guaranteed at the front, 6-piston aluminum monobloc brake calipers and rear floating caliper brake.
