FRANKFURT -- Porsche expects its Mission E electric car to account for about 10 percent of its vehicle sales after the car is launched in 2019.
"We have calculated a quantity in the order of about 20,000 for the Mission E," CEO Oliver Blume told Automobilwoche, a sister publication of Automotive News Europe.
The number is about a quarter of the volume achieved by the Macan SUV, the brand's top-selling model, which accounts about 40 percent of all Porsche sales. Last year Porsche's global vehicle sales rose 19 percent to 225,121 sports cars and SUVs.
Porsche unveiled the 600-hp Mission E concept at the 2015 Frankfurt auto show. The four-door car accelerates from 0 to 100 kph (62 mph) in under 3.5 seconds, beating the 911's 4.2 seconds to reach that speed. Porsche has said the Mission E will have a range of more than 500 km (310 miles).
The company is spending about 1 billion euros ($1.1 billion) to introduce the EV, which will be built in its Zuffenhausen plant in Stuttgart, Germany. Porsche's labor boss Uwe Huck has said that Porsche needs to sell at least 10,000 Mission Es a year to make a profit.
The Mission E is a part of parent Volkswagen Group's plan to move beyond its emissions-cheating crisis by launching 30 pure EVs across its brands by 2025 with sales of 2 million to 3 million EVs by then, accounting for 20 percent to 25 percent of its sales.
