Volkswagen Group's Seat unit will launch the production version of the el-Born electric hatchback under its standalone Cupra brand.
The Cupra el-Born will be the first performance-oriented car based on VW Group's modular MEB electric platform when it goes on sale in Europe next year.
The el-Born was unveiled as a Seat concept at the 2019 Geneva auto show.
Cupra has been chosen to launch the el-Born instead of Seat because the EV fits perfectly with Cupra's performance orientation and customer profile, Seat said.
Cupra CEO Wayne Griffiths said making the el-Born a Cupra performance model allowed the brand to differentiate it from VW Group's other MEB-based compact electric hatchbacks.
These include the VW ID3, which will go on sale in Europe in September, and the Audi Q4 e-tron and Q4 Sportback, both due next year. Skoda's version, called the Enyaq, will arrive by the end of the year.
"Seat and Cupra are essential for the development of the company. Each one has its clear role, its own personality and attributes and addresses different customer profiles," Griffiths said on Wednesday during a virtual press conference.
Engineers have developed a new dynamic chassis control system for the el-Born, Seat said. It adapts automatically to any conditions and offers a superior level of driving dynamics, the brand said. The Cupra el-Born can accelerate from 0 to 50 kph (31 mph) in 2.9 seconds.
The model has a 500 km (320 miles) range, thanks to its 77-kilowatt-hour battery that car be charged with the energy needed for at least 260 km in 30 minutes.
Seat CEO Carsten Isensee said there will not be a Seat version of the el-Born.
The Cupra el-Born will be built at VW's factory in German alongside the VW ID3 and Audi Q4 e-tron.
Skoda will build the Enyaq at its plant in Mlada Boleslav, Czech Republic.
