A fresh report out of Australia suggests the new 992-generation 911 GT3 RS will remain naturally aspirated … and there’s a chance its engine capacity will grow slightly, too.

Speaking to Wheels magazine, 911 product line chief August Achleitner confirmed the next GT3 RS would not make the switch to turbocharging.

He told the publication the lightweight, rear-wheel-drive GT3 RS would enjoy a little more power than the outgoing version (the latter worth 383 kW), while the high-revving flat-six could also grow slightly in size from the current 3 996 cc.

“It could get a small increase,” Achleitner told the Australian magazine, emphasising that any growth wouldn't be substantial enough to change the officially listed 4,0-litre capacity.

In addition, the report suggested the GT3 RS would not employ the Zuffenhausen-based automaker’s new eight-speed PDK transmission but rather retain the seven-speeder. A manual gearbox, meanwhile, would continue to be offered for the GT3.

At worst, expect the new model to remain the same weight as the 991.2 GT3 RS, although Achleitner hinted a slight mass reduction was on the cards.
