Audi will unveil an electric supercar concept that could signal the company is ready to add an e-tron version of its R8 supercar or even replace it altogether.
The PB18 e-tron will be revealed on Aug. 23 during the Pebble Beach Car Week in California.
The concept’s name refers to the Pebble Beach venue and the year of its debut, Audi said in a statement.
Some of technology on the car was "inspired" by elements of Audi’s Le Man winning R18 e-tron hybrid racecar, Audi said, without elaborating further.
Audi has announced and then cancelled an electric version of the R8 supercar twice in the last decade. The project was first cancelled due to its low 216-km (134-mile) range, then revived in 2015 as a low-volume production car after the range was increased to 450 km. It was cancelled again a year later.
Audi said earlier this year that it will build a full-electric e-tron GT "four-door sports car" starting in 2020 to sell alongside its upcoming e-tron SUV and e-tron Sportback “sports activity vehicle.”
The GT will be built at Audi’s Boellinger Hoefe site near its Neckarsulm assembly plant in Germany. Audi builds the R8 supercar on the same site, causing some media to speculate the GT could replace the R8.
Audi has said it will offer around 20 electrified models by 2025, of which more than half would be purely electric.
