Concepts, concepts and even more concepts. Audi's electric future is becoming ever-so clear. At least for concepts that is.

On cue, Audi announces an overflow of electric concepts for Frankfurt.

Audi e-tron Sportback Concept

Audi e-tron Sportback Concept

Without a shadow of a doubt, the all-new A8 flagship is going to be Audi’s big star at the forthcoming 2017 Frankfurt Motor Show. Fitted with an autonomous driving system meeting level 3 requirements, the full-size luxury sedan is going to be joined on stage by a pair of even more technologically advanced concepts, one with level 4 capabilities and another one presumably lacking a steering wheel and pedals as it will have level 5 status.

The first concept will take the shape of a coupe-SUV based on the E-Tron Sportback concept introduced earlier this year at Auto Shanghai. It will have the same overall length of 4.9 meters (16.1 feet) and trio of electric motors delivering a combined output of 496 horsepower (370 kilowatts). The zero-emissions showcar will be smart enough to do all the driving on the highway at speeds of up to 81 mph (130 kph) and even automatically change lanes without any human input.

As for the other concept, it will take the shape of a large car (D segment) with no less than four electric motors producing a yet unspecified amount of power. The fullsize model will have a battery pack with enough juice for 435 to 497 miles (700 to 800 kilometers) and Audi has made the promise it will feature a “spectacular and groundbreaking” design, inside and out.

The company isn’t specifying which of the two concepts is being showcased in the adjacent teaser sketch, but our money is on the level 5 autonomous car because of what looks to be a lower roof and a hexagonal windshield different than the E-Tron Sportback’s conventional glass. It has an imposing front end with a new take on Audi’s singleframe grille adorned by the four-ring logo illuminated in white and flanked by interesting panels featuring graphics that seem to be showing opposing triangles.

In related news, the Ingolstadt-based marque also says it will take the wraps off the hotly anticipated RS4 Avant set to share the spotlight with a rear-wheel-drive model coming from Audi Sport. We’re likely dealing with the rumored R8 GT heralding an array of RWD performance cars.
