The Audi allroad shooting brake - an all-purpose e-tron crossover that represents a glimpse at the future of Audi design

Audi has pooled the genes of its rugged allroad models and its forthcoming e-tron hybrids to create a striking and fittingly futuristic new crossover concept for this month‘s 2014 North American International Auto Show in Detroit.

Incorporating a host of design elements that define the brand's future vehicles, the Audi allroad shooting brake combines the elegant lines of a shooting brake with the purposeful stance of an allroad. As befits an allroad-themed study, its hybrid drive - which is as powerful as it is efficient - also makes a new form of quattro drive possible - e-tron quattro.

"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 of fuel (equating to 149 UK mpg) and cutting-edge electronic applications," says Prof. Dr. Ulrich Hackenberg, Member of the Board of AUDI AG, Technical Development. "We are offering very concrete glimpses of the near future in this show car."

The Audi allroad shooting brake represents the first time that Audi has combined elements of the allroad and e-tron model types.

Key features:

  • Powerful and efficient hybrid drive features two electric motors linked to conventional 2.0 TFSI with 292 PS output and 380 Nm torque
  • Total system power 408 PS and 650 Nm of system torque available
  • 0-62mph in 4.6 seconds, 155mph limited top speed, 149mpg and 45g/km CO2, according to appropriate standard, 502-mile driving range possible

The plug-in hybrid drive delivers impressive key performance data with 408 PS of system power and a system torque of 650 Nm (479.42 lb-ft). The show car, which weighs around 1,600 kg unladen, launches from a standstill to 62 mph in 4.6 seconds, and is capable of reaching an electronically limited top speed of 155 mph.

Fuel consumption is measured at 148.7mpg according to the relevant ECE standard, which equates to CO2 emissions of 45g/km. A total driving range of up to 510 miles is achievable.

A second electric motor, which is separate from the 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 Audi allroad shooting brake an e-tron quattro.

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 31 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.

Three modes for Audi drive select
Drive select management offers three driving modes. EV mode, which can be selected by a button on the multifunction steering wheel, prioritises 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 81 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 miles to the destination.
