At least 50 percent of the brand's sales will come from electrified models by 2025.

Porsche will introduce a second all-electric model in a bid to comply with strict emissions regulations looming in the European Union.

While the company declined to reveal what form it will take, insiders previously hinted it will be an SUV with roughly the same footprint as the Macan. It certainly won't be a sports car in the vein of the 911, and a second electric sedan looks unlikely at best.

"We're starting with a sporty four-door concept in the Mission E, positioned between the 911 and the Panamera, so it's logical that we will look to balance our line-up with a product in a different segment such as an SUV," said Porsche development boss Michael Steiner in an interview with Automotive News.

He added Porsche expects at least half of its sales will come from electrified models by the year 2025, the year stringent emissions norms will come into effect across Europe. Consequently, Porsche will have no problems complying with the new regulations.

Steiner explained he's worried about government officials ultimately regulating certain technologies -- like gas and diesel -- out of the market completely. His comments suggest the flat-six will remain a key part of the Porsche experience in the foreseeable future, at least if decision-makers have their way.

"Customers should be the ones to decide," he opined.
