Rugged-looking show car features an electric motor for each wheel, and limited self-driving ability in off-road situations.
The covers have been whipped off the Audi AI:Trail Quattro concept at the 2019 Frankfurt motor show.
The concept features four electric motors which can work together to generate a maximum of 320kW of power and 1000Nm of torque.
As there’s an electric motor for each wheel, the AI:Trail can do without weight-adding, energy-consuming differentials and locks. Said to be made from a mixture of steel, aluminium and carbon-fibre, the AI:Trail tips the scales at 1750kg.
To ensure the car has as much range as possible both on- and off-road, top speed is limited to 130km/h. Audi says the car has an on-road range of between 400 and 500 kilometres, while off-road driving range drops to 250km as there’s almost constant wheel slippage.
As the last vehicle in Audi’s AI line of concepts, the AI:Trail is said to have Level 4 self-driving abilities on selected sealed roads, including highways and inner city areas with the appropriate infrastructure.
On unpaved roads the concept is capable of Level 3 self-driving on roads and tracks that have been well mapped. Even then the autonomous system will only drive at low speeds, giving the driver several seconds in which to intervene or take over when necessary.
For more rugged terrain the AI:Trail will keep track of ground clearance, and approach and departure angles, and warn the driver if the car’s limits are about to exceeded. In some situations the car’s electronics will also actively keep the vehicle within the clear track.
The AI:Trail is short but chunky, measuring 4.15m long, 2.15m wide and 1.67m tall. It rides on 22-inch alloy wheels with broad 850mm tyres.
Thanks to its 340mm ground clearance, the AI:Trail can ford water up to half-a-metre deep.
Audi says the car’s large glasshouse, which includes a transparent interpretation of brand’s single-frame grille design, allows passengers to have an expansive view of the trail they are travelling on.
