The Driveline
The 2.0 TDI transmits its power to a six-speed manual transmission. The 3.0 TDI and 2.0 TFSI feature the next generation of Audi's dynamic and very efficient S tronic. This innovative dual-clutch transmission switches extremely smoothly among its seven gears within a few hundredths of a second. S tronic also excels thanks to its high efficiency ratio and a broad spread of the gear ratios. The seven-speed S tronic has a fully automatic mode at the ready: the driver can shift as required, if necessary via shift paddles on the steering wheel.

In the Audi A4 allroad quattro drivetrain, the differential is in front of the clutch and immediately behind the engine. This technical stroke of genius made it possible to reposition the front axle much closer to the vehicle's front end, in turn allowing for a long wheelbase and an ideal distribution of the axle loads. The benefits include steady straight-line stability, superb ride comfort, and excellent driving dynamics.

The Audi A4 allroad quattro features quattro permanent all-wheel drive as standard equipment. Its purely mechanical center differential favors the rear, distributing power at a 40:60 ratio to the front and rear axle. If necessary, the quattro permanent all-wheel drive can route up to 65 percent to the front or as much as 85 percent toward the tail end.

The Chassis
The width of the Audi A4 allroad quattro lays the foundation for its driving dynamics. The car's track is 1,583 mm (62.32 in.) at the front and 1,574 mm (61.97 in.) at the rear - some 20 mm (0.79 in.) wider, respectively, than the A4 Avant. The body is higher on account of a new chassis with longer springs, which - like the new shock absorbers - combine sportiness with comfort. The standard, 17-inch lightweight alloy wheels are fitted with 225/55 tires. At a diameter of 690 millimeters (27.17 inches), even this standard configuration looks rather imposing. For the time being, Audi is also offering 18-inch wheels.

The chassis in the A4 allroad quattro retains all the advantages which distinguish the A4 model line. Steering is straightforward and responsive. A steering box beneath the wheel conveys the driver's input directly to the wheels. The five-link front suspension and the self-tracking trapezoidal-link rear suspension consist largely of aluminum to reduce unsprung weight. 16-inch brakes with excellent cooling behavior provide for rapid deceleration. It should come as no surprise that the A4 allroad quattro offers sportiness, comfort, and stability - onroad and offroad. After all, it is an A4.

On rough terrain, the A4 allroad quattro relies on a high-tech feature of its Electronic Stabilization Program (ESP): the Offroad Detection (ORD) technology automatically identifies the type of driving surface and adjusts the ESP's control parameters accordingly. When the driver depresses the gas pedal, ESP increases propulsive power by tolerating more wheel spin than otherwise. If necessary, it will override for a time in the interests of safety.

On paved roads, Audi drive select further enhances the joys of driving. This control system automatically and perfectly adapts the personality of the Audi A4 allroad quattro to the driver's preferences. Audi drive select namely evaluates the engine's throttle response, the Servotronic power steering, and S tronic's shift points in automatic mode. The driver can freely switch among three different engine maps: comfortable, standard, and sporty. And MMI navigation plus provides yet another on-board control option, and is individually programmable.

Audi drive select can be paired with Audi dynamic steering. It consists of a superimposed gear system, and varies the steering ratio as well as steering assistance in a continuously variable manner. Audi drive select functions directly at low speeds and indirectly at high speeds. At the vehicle's cornering limit, the dynamic steering keeps the A4 allroad quattro on course via split-second corrective actions - subsequently obviating extensive ESP intervention.

Equipment Packages
The Audi A4 allroad quattro will be available at dealerships early this summer at a basic price of 37,100 euros. It is generously equipped with 17-inch lightweight alloy wheels, fog lights, a headlight washer system, roof rails, a convenient luggage-compartment cover, a reversible loadliner, an automatic climate-control system, an electromechanical handbrake, and a sound system with CD player.

Optional equipment also includes a multitude of attractive features. The high-beam assistant automatically switches between high beams and low beams. The two-part panoramic glass roof with an electrically operated interior shade suffuses the interior with sunlight and fresh air. And the electromechanical tailgate, the ingenious three-zone climate-control system, the xenon plus headlights with LED daytime running lights and LED reverse lights, and the climate-controlled comfort seats are all luxurious options.

If a customer so desires, they can take delivery of an A4 allroad quattro with innovative assistance systems straight from the luxury class. Audi lane assist helps the driver to remain in a given lane, while Audi side assist makes it safer to change lanes. Adaptive cruise control is a radar-assisted cruise-control system which detects vehicles ahead and maintains the proper following distance by braking and accelerating on its own. Should the rate of deceleration for some reason not suffice, the system alerts the driver via one of two alarms based on the extent of danger.

Audi also offers top-notch multimedia options. The world-class MMI navigation plus system belongs to Audi's cutting-edge generation of new high-tech devices. It integrates a color display with three-dimensional maps, a DVD player, a voice-activated unit facilitating whole-word commands, and a large hard disk drive which stores data for navigation, music, and phoning. MMI navigation plus can be rendered even more sophisticated by means of tuner modules which enable digital TV/radio reception. Last but not least, a Bang & Olufsen sound system indeed constitutes a luxurious extra: its 14 speakers delivering 505 watts create breathtaking surround sound.
