The company is waiting for better batteries before bringing the electrified 992 to market.
Porsche has narrowed the time-frame for launching a 911 plug-in hybrid.
The forthcoming 992-generation will be the first electrified production 911, but Porsche CEO Oliver Blume cautions that a plug-in variant will not be immediately available.
"We are waiting for the further evolution in battery technology so you should not expect a plug-in version in the coming years," he recently told reporters, according to Automotive News Europe. "It's currently planned when the 992 is refreshed."
The company previously claimed that current battery technology does not meet its minimum performance requirements for the 911 family.
The upcoming Mission E features a unique 800-volt battery configuration, claimed to be capable of handling track sessions without going into a limp mode to prevent overheating. The 911 will not be offered in all-electric form, though the company is considering such variants for the Boxster and Cayman.
