Audi has revealed the e-tron quattro concept at this year's Frankfurt Motor Show. The concept previews the brand's first large-scale production electric car, due in 2018.

“Audi will present an all-electric, luxury-class sport SUV in early 2018. The Audi e-tron quattro concept provides a concrete foretaste of this. It combines driving pleasure with great range, an expressive design and excellent comfort,” said Prof. Dr. Ulrich Hackenberg, Member of the Audi Board of Management for Technical Development.

Up front, the e-tron quattro concept is fitted with Audi's slim-line headlights, a large grill, an aggressive bumper and a sculpted hood. Turning at the side, the e-tron quattro concept is characterized by sharp lines, a sloping roofline and prominent wheel arches. The exterior mirrors are replaced with a rear-view camera mounted on the fenders.

The rear of the e-tron quattro concept comes with wraparound taillights, a roof-mounted spoiler and a diffuser. It also has a thick body cladding seen at the bottom of the car.

Interior of the Audi e-tron quattro concept

Inside, Audi says the e-tron quattro concept can accommodate four occupants along with 615 liters of luggage space. The interior features Audi's virtual cockpit that debuted in production vehicles in 2014. It also has a flat-bottomed steering wheel as well as a fully-digital instrument cluster with two touch displays finished in black glass and a subtle aluminium frame.

The e-tron quattro concept is powered by three electric motors: one motor drives the front axle while the two others act on the rear producing a total output of 435 PS. Audi says the concept comes with a boosting function that can temporarily increase its maximum output to 503 PS and over 800 Nm of torque. Audi claims the concept can go from 0 to 100 km/h in 4.6 seconds before hitting a top speed of 210 km/h.

The lithium-ion battery is integrated into the floor of the passenger compartment and has a capacity of 95 kWh, which provides a range of more than 500 km. It can be charged through DC or AC electrical current. Audi says a full charge with DC electrical current at a charging point with an output of 150 kW takes just around 50 minutes. As an alternative, the concept is equipped with Audi Wireless Charging technology for contactless induction charging.
