To stay under increasingly strict CO2 emission limits in major markets, Volkswagen Group expects it will have to sell about 1 million battery electric and plug-in hybrid vehicles a year by 2025, reports Automotive News Europe .

The Group currently offers three electric car—the VW e-Up, the e-Golf, and the the Audi R8 e-Tron—and six plug-in hybrids—the VW Golf GTE, Passat GTE, Audi A3 Sportback e-Tron, Q7 e-tron quattro, Porsche Panamera S E-Hybrid, and Cayenne S E-Hybrid.

By 2020, though, Volkswagen hopes to add another 20 new electric and plug-in hybrids to the range. These include Porsche’s Mission E electric car and the Audi e-tron quattro, which will by the Audi’s first mass production EV.

So far, though, electrified vehicles have been a relatively small slice of the pie chart of Volkswagen brand sales. At the end of this year, Volkswagen is expected to have sold slightly more than 100,000 electrified since 2010. Toyota, by comparison, sells about 75,000 Prius plug-in hybrids a year.

Despite that, VW brand production chief Thomas Ulbrich says that VW could build up to 75,000 electrified vehicles and that the number could easily rise if demand did.

Helping VW along to its goal will be the new MEB platform that whose development was announced  in October. VW says that the new platform will allow the company to build emotionally appealing EVs with a range of up to 310 miles.
