At the 2013 Frankfurt Motor Show Audi will prosent the Sport quattro Concept, a show car that celebrates the 30th birthday of the 1983 Sport quattro.
The concept takes up the ideas first seen in the Audi quattro concept study three years ago and introduces a new hybrid system with a total output of 515 kW (700 hp).
The exterior design is characterized by a verly low stance – the total height is just 1,386 mm – enhanced by the minimal overhangs and large 21-inch wheels with 285/30 tires.
Among the design elements inspired by the quattro models of the early 1980s are the angular, flat C-pillars and the rectangular double headlights featuring Audi’s Matrix LED technology, which will be available by the end of this year in the restyled Audi A8.
Comapred to the 2010 show car, the new Sport quattro Concept has lost the distinctive hood scoop, and the headlights area has a different surface treatment and layout. The sides showcase new air openings behind the front wheels that give the panels a sculpted look.
At the rear, the original fascia, framed by beveled contours, has been replaced by a more conventional design, and the twin, square-shaped tail lamps left out for a more production-ready solution.
Additionally, the front grille has a new racing-inspired, sculpted grille insert with a vertical lower section and an upper section that follows the line of the hood.
Below we report the official design details. Check back soon for the design gallery.
With a wheelbase of 2,784 millimeters (109.61 in), it is 4,602 millimeters (181.18 in) long. With 1,964 millimeters (77.32 in), the two-door model is very wide and at just 1,386 millimeters (54.57 in) unusually low-slung.
Two very flat structures are visible inside the headlight. The wrap-around daytime running lights together with the central low-beam units and the Audi Matrix LED make for a sporty, determined look. The headlights and tail lights are a reinterpretation of lightweight construction.
The headlights forsake fascia, exposing the LED heat sinks, while the tail lights reduce glass and housing to a minimum.
The LED high-beam unit of the Audi Matrix LED headlights is comprised of numerous individual diodes. The individual LEDs, which work in tandem with upstream lenses and reflectors, always deliver excellent illumination. They are activated, deactivated or dimmed individually according to the situation. With the number of LEDs, their arrangement and the size and design of the headlights, the new technology offers many fascinating possibilities.
Another design homage are the “blisters” above the fenders. The Audi designers have reinterpreted and strongly accentuated these lines. They give the body even greater emotional appeal and broad shoulders. Throughout the car, sharp contours frame tautly muscular surfaces. With their interplay between convex and concave curvatures, the engine hood, fenders and flanks define the athletic character of the Audi
Sport quattro concept.
New details: the single-frame grille
The front of the show car is characterized by the hexagonal single-frame grille with a new, sculpted grille insert, a typical element borrowed from racing. Its lower section is virtually vertical; the upper section follows the line of the engine hood.
The low grille emphasizes the width of the car. Two large, vertical blades divide each of the large air inlets, and their form is taken up by the creases in the engine hood. The CFRP splitter is shifted far to the front, as on a race car. The grille is part of Audi’s new design philosophy and provides a first glimpse at the future design of the sporty production models.
The proportions of the rear of the car are defined by the combination of a flat greenhouse and broad shoulders. The spoiler at the lower edge of the rear window underscores the car’s width. Another distinctive element at the rear of the show car is the CFRP diffuser, which extends far upward. Similar to the single-frame grille, its upper section is honeycombed, whereas the lower section houses two large, oval tailpipes. Mounted on a black CFRP facing, the tail lights are rectangular – a typical quattro styling cue – and emphasize the width of the car. A spoiler extends from the rear hatch at higher speeds. The luggage compartment, which is reinforced by a solid crossbeam beneath the rear shelf, has a capacity of 300 liters (10.59 cubic ft).
Precisely penned details round out the dynamic look of the Audi Sport quattro concept. The flared sills are made of CFRP; the power door handles extend automatically to meet an approaching hand. The four rings adorn the front, the rear, the air outlets behind the front wheels and the C-pillars. The center-locking wheels feature a five twin- spoke design.
The interior is focused on the driver. The steering wheel, digital instrument cluster and head-up display are all in the direct field of view. A line running below the windshield encircles both the driver and passenger and integrates all ergonomic functions such as the door openers.
Viewed from above, the slim dashboard is reminiscent of the wing of a sailplane. The support structure of the interior is a carbon shell that also serves as a storage compartment in the side doors. Elements like this make lightweight construction visible.
The quattro drivetrain runs beneath the continuous center console. Sporty racing bucket seats with folding backs, sculpted side bolsters and integrated head restraints up front and full rear seats offer space for four.
The folding mechanism provides access to the rear. A crossbeam behind the rear seats provides for additional rigidity.
The multifunction sport steering wheel is used to switch between a number of virtual 3D displays. All important information is displayed in the fully digital instrument cluster.
Choices include a Race mode with central speedometer, track information and a stopwatch, for example, or the Setup mode with detailed information about numerous race tracks. In addition, the touchwheel of the characteristic Audi MMI control unit makes it easy to enter information.
The innovative air conditioning control unit is integrated directly into the air vents. Temperature, intensity and air flow can be controlled using one and the same element. The display in the vents shows either important media information or the air conditioning settings.
The plug-in hybrid drive makes the Audi Sport quattro concept a breathtakingly dynamic coupe. System output is 515 kW (700 hp); system torque is 800 Nm (590.05 lb-ft).
Power flows through a modified eight-speed tiptronic to the quattro powertrain, which features a sport differential on the rear axle. According to the applicable standard, the show car consumes on average 2.5 liters of fuel per 100 kilometers (94.09 US mpg), a CO2 equivalent of 59 grams per kilometer (94.95 g/mile).
The combustion engine is a four-liter, twin-turbo V8. It produces 412 kW (560 hp) and 700 Nm (516.29 lb-ft) of torque. The cylinder on demand (COD) system, which deactivates four cylinders under part load, and a start-stop system make the sonorous eight-cylinder unit very efficient.
Located between the 4.0 TFSI and the transmission is a disc-shaped electric motor producing 110 kW and 400 Nm (295.02 lb-ft). It draws its traction energy from a liquid-cooled lithium-ion battery in the rear with a capacity of 14.1 kWh.
The show car is charged via an Audi wall box, which uses intelligent charge management to ensure the optimal feed of energy to the lithium-ion battery.
The Audi Sport quattro concept can cover up to 50 kilometers (31.07 miles) on electric power alone. An intelligent management system controls the interplay between the two drives as needed, and the driver can choose between various operating modes.
When the V8 and the electric motor work together, the Audi Sport quattro concept accelerates from 0 to 100 km/h (62.14 mph) in 3.7 seconds – much like the powerful Audi rally cars once did. Its top speed is 305 km/h (189.52 mph).
The lightweight construction concept also plays a large part in this dynamic performance. The occupant cell combines ultra-high-strength steel panels and cast aluminum structural elements.
The doors and fenders are made of aluminum, and the roof, the engine hood and the rear hatch are made of carbon fiber-reinforced polymer. The result is a curb weight including the battery pack of just 1,850 kilograms (4,078.55 lb).
