Viewed from the side, the vehicle dazzles with flared wheel arches, angular sills (available with stainless-steel insert strips), and large wheels – 17-inch wheels in 7-arm design are standard. The roof is capped off by an offset rail with two high crosspieces. The width of the A4 allroad quattro is emphasized by the rear bumper’s distinctive styling and the integrated horizontal reflectors. On the 2.0 TDI, the two exhaust tailpipes appear side by side; on the 2.0 TFSI and 3.0 TDI, they terminate to the left and to the right.
The Audi A4 allroad quattro is a truly expressive car. Its measurements include: 4.72 meters (15.49 ft) in length, a wheelbase of 2.81 meters (9.22 ft), 1.84 meters (6.04 ft) in width, and 1.50 meters (4.92 ft) in height. It also features greater ground clearance than the Audi A4 Avant: 180 millimeters (7.09 inches) when the Audi A4 allroad quattro is unloaded.
Audi has created a vehicle body consisting primarily of high-strength and ultra-strong steel panels – which, in turn, reduce the car’s weight while enhancing its rigidity, vibrational comfort, and impact safety. An array of precisely arranged metal sections protects passengers in the event of an accident.
In addition to the two front airbags, which take into consideration the precise positions of the driver and front-seat passenger, there are side air bags in the front and, optionally, in the rear as well. Last but not least, a head-protection airbag system also stands at the ready. The integral head-restraint system in the front diminishes the risk of whiplash in the event of a rear-end collision.
The luggage compartment’s base capacity is 490 liters (17.30 cubic feet). This can be increased, however, to an impressive 1,430 liters (50.50 cubic feet) and a length of 1.78 meters (5.84 feet) by folding down the split rear-bench backrest, which optionally features a load-through hatch with removable ski bag. The hatch is exactly one meter wide (3.28 feet). The luggage compartment boasts an ingenious design which enhances its use and is lined with high-quality carpet.
Audi will initially offer three different engines for the A4 allroad quattro: a gasoline engine and two diesel engines. All three are turbocharged direct-fuel-injection engines. They command respect due to excellent performance, impressive pulling power, smooth running, and high fuel efficiency. The engines are further bolstered by pioneering technologies arising from Audi’s modular efficiency expertise. For example, all three units boast a standard on-board recuperation system, which converts mechanical energy into electrical energy during deceleration.
The 2-liter TFSI – voted “Engine of the Year” on four consecutive occasions by an international panel of experts – incorporates three high-end technologies: FSI direct gasoline injection, the turbocharger, and the Audi valvelift system, which boosts pulling power by means of a variable control system. Between 1,500 and 4,200 rpm, the four-cylinder engine delivers 350 Nm of torque to the crankshaft. Peak output is 155 kW (211 bhp). In addition, the 2-liter TFSI propels the Audi A4 allroad quattro to 100 km/h (62.14 mph) in just 6.9 seconds, and to a top speed of 230 km/h (142.92 mph). On average, it consumes a mere 8.1 liters of fuel per 100 km (29.04 mpg).
As for the 2.0 TDI, the successor to the most successful diesel engine ever, a common-rail system providing injection pressure of 1,800 bar ensures excellent driving refinement. The two-liter diesel engine delivers 350 Nm between 1,750 and 2.500 rpm. A respectable 125 kW (170 bhp) provides admirable output, yet requires just 6.4 liters of fuel per 100 km (36.75 mpg). The Audi A4 allroad quattro 2.0 TDI reaches 100 km/h (62.14 mph) in 8.9 seconds and a top speed of 213 km/h (132.35 mph).
The very best of the three engines is the 3.0 TDI. This V6 diesel produces 176 kW (240 bhp) and transmits 500 Nm of torque to the crankshaft at 1,500 to 3,000 rpm. The 3.0 TDI in conjunction with S tronic propels the Audi A4 allroad quattro to 100 km/h (62.14 mph) in 6.4 seconds, and tops out at 236 km/h (146.64 mph). On average, the three-liter engine sips only 7.1 liters of fuel per 100 km (33.13 mpg). Like the other two engines, it already meets the EU’s Euro 5 emission standard.
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.
