Audi TT Offroad Concept


The Audi TT offroad concept breaks the mold, combining the sportiness of a coupe with the lifestyle and utility of a compact SUV. The four-door model, which Audi has presented at the 2014 Beijing International Automobile Exhibition, adds an entirely new expression to the Audi design language.

The plug-in hybrid drive in the Audi TT offroad concept delivers 408 hp of system output and 650 Nm of system torque. The show car accelerates from 0 to 100 km/h in 5.2 seconds and reaches the electronically governed top speed of 250 km/h without any trouble. It consumes just 1.9 liters of fuel per 100 kilometers, a CO2 equivalent of 45 grams per kilometer. The Audi TT offroad concept can drive over 50 kilometers solely on electric power and thus with zero local emissions, and has a total range of up to 880 kilometers.

The combustion engine is a 2.0 TFSI producing 292 hp and 380 Nm of torque. The two-liter, four-cylinder unit with the large turbocharger is packed with Audi's potent efficiency technology. At part load, indirect injection supplements gasoline direct injection for lower fuel consumption. The exhaust manifold is integrated into the cylinder head - the foundation for the high-performance thermal management system.


A separating clutch links the transverse 2.0 TFSI to an electric motor producing 40 kW and 220 Nm of torque. The slim, disc-shaped electric motor is integrated into the six-speed e-S tronic. The dual-clutch transmissions sends the torque to the front wheels. Mounted on the rear axle of the Audi TT offroad concept is a second electric motor independent of this drive unit. This produces a maximum of 85 kW and 270 Nm. In front of the rear axle is a liquid-cooled, lithium-ion battery comprising eight modules. It contributes to the balanced 54:46 weight distribution between the front and rear axles and to the low center of gravity. The battery stores up to 12 kWh of energy, enough for an electric range of 50 kilometers. An Audi wall box, which manages the energy feed conveniently and intelligently and can deal with a variety of voltages and outlets, is used for stationary charging.

The show car is also designed for use with Audi Wireless Charging technology for contactless inductive charging. The infrastructure side - a plate with a coil and an inverter (AC/AC converter) - is placed on the parking spot of the Audi TT offroad concept and connected to the power grid. The charging process begins automatically when the car drives onto the plate. The alternating magnetic field of the infrastructure side induces a 3.3 kW alternating current across the air gap in the secondary coil, which is integrated into the vehicle. The current is inverted and fed into the electrical system. Charging stops automatically when the battery is fully charged. It takes about as long as charging via a cable, and the driver can interrupt the process at any time. The Audi Wireless Charging technology is more than 90 percent efficient, and is not affected by weather factors such as rain, snow or ice. The alternating field, which is only generated when a car is on the plate, is not harmful for people or animals.


The Audi TT offroad concept shows its strong character on any road surface and in any terrain. On asphalt the show car is sporty and composed, and it can easily handle light terrain thanks to its high ground clearance, short overhangs and e-tron quattro all-wheel drive. 255/40-series tires are mounted on 21-inch wheels, whose delicate five-arm design draws on the look of the Audi e-tron models. Dark trim provides contrast.

Many of the components of the McPherson front suspension are made of aluminum; the four-link rear axle handles longitudinal and transverse forces separately. The ratio of the progressive steering changes with the steering input. The Audi drive select system allows the driver to modify the function of various technical modules in multiple steps.

The Audi TT offroad concept show car features two Audi driver assistance systems that are almost ready for production: the intersection assistant and online traffic light information technology. The intersection assistant aims to help to avoid side-impact collisions, or reduce their severity, where lanes merge and at intersections. Radar sensors and a wide-angle video camera scan zones to the front and sides of the car. If the system detects a vehicle approaching from the side and assesses it to be critical, graduated warnings are displayed in the Audi virtual cockpit.


4.39 meters long, 1.85 meters wide and a wheelbase of 2.63 meters - in these dimensions the Audi TT offroad concept resembles today's compact SUV, the Audi Q3. At 1.53 meters tall, however, it is 8 centimeters shorter, making its sporty character obvious at first glance. The Sonora Yellow outer skin appears to have been modeled from a solid block; the interplay of the clearly drawn lines and the muscularly taut surfaces produces a highly dramatic design. It uses the design language of the Audi TT, but places its elements in a new context.

Horizontal lines dominate at the front of the new Audi TT offroad concept. The broad Singleframe grille bearing the four rings is sculpturally embedded in the body. Two subtle indents in the lower region make the grille appear lighter. Narrow louvers in the grille insert form a structure typical of the Audi e-tron models.

The large air inlets below the Matrix LED headlights are framed in sharp edges and structured with louvers. A third, flat inlet below the grille joins them together. Inside is a blade that increases downforce on the front axle and makes the front of the Audi TT offroad concept appear even wider.


The interior of the Audi TT offroad concept offers space for four. The rear seat can accommodate two adults comfortably. The slim sport seats with integrated head restraints ensure lateral hold. The side bolsters of the front seats are very strongly contoured.


The show car is equipped with three Audi Smart Displays. The fast tablets serve as a mobile infotainment system for use inside and outside of the car. From DVD or TV streaming to controlling the radio or navigation planning, the Audi Smart Display is extremely versatile. One click on the "more" button in the start menu establishes an Internet connection via Audi connect at LTE speed. The user now has access to all of the functions of the Android operating system, from browsing with Google Chrome to visiting the Google Play store.
