While Porsche continues to heavily invest in its electrification program, the Porsche 911 and 718 Boxster/Cayman remain combustion-engined only. An all-electric 718 is expected, at least as an option, with its next major redesign as its mid-engine layout is ideally suited for a floor-mounted battery pack. Adapting the famously rear-engined 911 to house an electric powertrain, however, is way more challenging.

But a plug-in hybrid 911 is not only possible but is reportedly in development. Not expected to arrive for a few more years, the hybridized 911 will not be the ultra-fuel efficient sports car some might think, but rather a serious performance machine. It wouldn't be a proper 911 any other way.

Speaking to Autoblog, Porsche CEO Oliver Blume has made this fact very clear. "To think in the future for the 911, there are good ideas for a special kind of hybrid, a very performance-oriented hybrid where we use, for example, a 400-volt system for our electric motor and for the power electronics, like we use in our plug-in hybrids, with a high power density," he said. "We want to have a very high power [output] with very big performance and driving ability. That's more or less our idea of how to continue with the 911."

If you're looking for a zero-emissions Porsche, there's the all-electric Taycan.

Unlike say, a Toyota Prius, a future 911 Hybrid is all about performance and fuel efficiency is a very distant second, at best. Blume did mention "there is also space for a very sporty pure electric two-door sports car," but no final decision has been made yet and the 911 will retain its flat-six engine "for a long time to come."

Porsche has already proven incredible performance can be achieved with a plug-in hybrid setup; look no further than the 689 horsepower Panamera Turbo S E-Hybrid. Is it fuel-efficient for its class? Yes, but performance and handling is the main objective. The Porsche 911 will never sacrifice performance for efficiency.
