The Audi Allroad Shooting Brake makes its debut at the North American International Auto Show (NAIAS) in Detroit. It is a 2-door crossover allowing it to go off the beaten path and with its high level of functionality, it is ideal for recreational sports.
“The show car combines sex appeal, highly efficient e-tron-quattro technology that produces 300 kW of power yet only consumes 1.9 l/100 km (123.80 US mpg) of fuel and cutting-edge electronic applications. We are offering very concrete glimpses of the near future in this show car,” says Prof. Dr. Ulrich Hackenberg, Member of the Board of AUDI AG, Technical Development.
The Audi Allroad Shooting Brake combines a host of visual elements of future sports car models with the Audi-typical allroad concept and "shooting brake” car body form. Its user interface strategy also offers an outlook on future production solutions.
The Audi Allroad Shooting Brake combines the allroad and e-tron form languages together seamlessly. Like the e-tron model, it has an insert with narrow fins, which resemble the cooling ribs of an electronic component. There is a quattro logo on the lower part of the single-frame. The low-profile central air inlet is milled into the underbody protection that is made of aluminum.
There is plenty of room for four passengers inside. In front, the narrow sport seats give the driver and front passenger optimal body support; they feature highly contoured lateral panels and integrated head restraints, while cushioned pads support the thighs in quick driving through curves. An easy entry function makes it easier to enter the rear seating area. When the rear seatback is folded down, a cargo area with a level cargo floor is created, in which there is space for rather large sports equipment.
The Audi Allroad Shooting Brake plug-in hybrid drive delivers impressive key performance data with 300 kW (408 hp) of system power and a system torque of 650 Nm (479.42 lb-ft).
The show car, which weighs around 1,600 kg (3527.40 lb) without the driver, launches from a standstill to highway speed (62.14 mph) in 4.6 seconds, and its forward acceleration does not quit until it is electronically limited at 250 km/h (155.34 mph). Low fuel consumption figure of 1.9 liters of fuel per 100 km (123.80 mpg) (45 g CO2 per km [72.42 g/mile]) based on the relevant ECE standard. Its total driving range is up to 820 km (509.52 miles).
The 2.0 TFSI in the Audi Allroad Shooting Brake outputs 215 kW (292 hp) of power and generates 380 Nm (280.27 lb-ft) of torque. The transverse mounted two-liter four-cylinder with a large turbocharger is a high-end engine. In part-load operation, indirect injection supplements direct gasoline injection to improve fuel economy; the exhaust manifold that is integrated in the cylinder head enables high-performance thermal management.
The 2.0 TFSI operates together with a disc-shaped electric motor via a decoupling clutch; the electric motor outputs 40 kW of power and 270 Nm (199.14 lb-ft) of torque. It is integrated in the six-speed e-S tronic. The dual clutch transmission, which shifts at lightning speed, sends torque to the front wheels.
A second electric motor, which is separate from this drive unit, is mounted to the rear axle. It supplies propulsive power at low and moderate vehicle speeds with its maximum power of 85 kW and 270 Nm (199.14 lb-ft) of torque. It can also be operated in tandem with the motor and engine at the front axle if the hybrid management system decides that all-wheel drive makes sense. In such situations, e.g. on a slippery road or in light off-road conditions, this essentially makes the
Located just forward of the rear axle is a lithium-ion battery that consists of eight modules. It contributes towards a balanced distribution of weight, and it hardly affects cargo capacity at all. The liquid-cooled battery has an energy capacity of
8.8 kWh, which is enough for 50 km (31.07 miles) of all-electric driving. An Audi wall box is used for stationary charging; it can operate with different voltages and plug connector types, and it regulates the energy transfer conveniently and intelligently.
Drive select management offers three driving modes. There is the EV mode, which can be selected by a button on the multifunction steering wheel; it prioritizes all-electric driving. Here, the front drive unit is inactive, and the electric motor at the rear axle with its powerful torque can rapidly accelerate the two-door car to a top speed of 130 km/h (80.78 mph).
In Hybrid mode, the drive sources operate highly efficiency, and they work together in various ways as necessary. In many situations, the electric motor in front acts as a generator – driven by the engine, it charges the battery, and this extends the car’s effective electric driving range.
In Sport mode, which the driver can select via the Audi drive select system, the car's full system power is available. When a high level of power is demanded by the driver, the electric motor at the rear axle works together with the 2.0 TFSI in a boost mode, in which both drive units output propulsive power.
Depending on the driving situation, releasing the accelerator pedal can cause all drive units to be decoupled, or it can result in energy recovery by regenerative braking. In the first case, the show car coasts with zero emissions since the combustion engine is shut off; in the latter case, braking energy is fed back into the high-voltage battery.
The driver can use the "Hold" and "Charge" functions in the MMI user interface to specifically influence the battery's charge state, e.g. to increase storage of electric energy so that it can be used over the final kilometers to the destination.
