The 2005 Audi Allroad Quattro Concept is a rugged yet sophisticated take on the A6 Avant, designed to offer both on-road refinement and off-road capability. Sharing its bodyshell and proportions with the newly introduced A6 Avant, this concept builds upon the executive-class wagon’s sleek lines while enhancing its all-terrain credentials. Measuring 4.93 meters in length and 1.89 meters in width, it maintains the Avant’s stately dimensions, but with an extra 60mm of ride height, providing increased ground clearance for off-road adventures.
At first glance, the Allroad Quattro Concept exudes strength and capability, thanks to its muscular stance, flared wheel arches, and underbody protection made of stainless steel with a ribbed structure. Striking bumpers and a widened track further highlight its off-road potential, while the signature single-frame grille and sweeping roofline maintain Audi’s sporty elegance.
A major highlight of the concept is its advanced lighting technology. The LED headlamps feature modular structures, with 14 individual LEDs delivering the same illumination as xenon headlights, complemented by 10 additional high-beam LEDs. The brake lights, turn signals, and taillights also employ high-speed LED technology, with integrated mirror-mounted indicators enhancing visibility.
From the side, the concept’s design stays true to Audi’s Avant philosophy, with a high shoulder line, coupe-like roofline, and low-raked tailgate. Contrasting bumpers, door sills, and wheel arches add a functional ruggedness to the aesthetic, while the 19-inch wheels wrapped in 255/45 R19 tires ensure a commanding road presence. The rear design continues the powerful stance, with two-piece taillights curving inward, reinforcing its sporty yet robust character.
A standout feature is the Open Sky glass sliding roof, covering almost the entire area between the A- and D-pillars. Composed of two large glass segments, the front panel opens electronically, flooding the cabin with natural light. The exterior glass and mirrors boast a hydrophobic nanocoating, repelling water and dirt, improving visibility in wet conditions.
Inside, the Allroad Quattro Concept’s interior is designed for luxury, functionality, and advanced technology. With a four-seat configuration, the high center console extends from the front to the rear, featuring intelligently subdivided storage compartments beneath split-opening armrests. The cockpit prioritizes driver engagement, with the instrument panel seamlessly integrated into the center console, covered in premium leather for a unified, high-end look.
At the heart of the dashboard is an 8.9-inch MMI display, offering an impressive 1024x600 resolution, significantly clearer than the standard 7-inch screens of the time. The horizontal center console houses the engine start button, an electromechanical parking brake, the selector lever for the six-speed automatic transmission, and the MMI control unit, ensuring an ergonomic and driver-focused layout.
The 2005 Audi Allroad Quattro Concept showcases Audi’s vision of a luxury all-terrain vehicle, blending Avant practicality, off-road capability, and cutting-edge technology. With its striking design, innovative features, and rugged elegance, it stands as a bold expression of Audi’s engineering excellence.
