Bentley may have delayed itsupcoming 1,400-horsepower electric model, but the luxury automaker has plenty of plug-in hybrid models coming to hold its customers over in the meantime.

As early as 2018, Bentley was spotted testing a Continental GT PHEV, though nothing has materialized in the four years since it was first seen. The project hasn't been scrapped, as our spy photographers captured the plug-in coupe testing a few months ago.

CarBuzz can now confirm that the Continental GT will not be the only model to receive the PHEV treatment. These new spy shots show a prototype 2023 Bentley Continental GT Convertible testing with two fuel doors, a telltale sign of a PHEV. The charge port lives on the left rear fender, while the fuel door is on the other side.

Aside from the Ferrari SF90, the Continental GTC will be the only plug-in convertible available in the United States. These two aren't exactly competitors, so the Continental GTC should have the market to itself. It's unclear exactly which drivetrain Bentley will use for the Continental GT and GTC PHEVs, though it's likely that the two will share the same setup.

The Bentayga Hybrid employs a 3.0-liter turbocharged V6, working with electric motors to deliver 456 horsepower. Meanwhile, the Flying Spur Hybrid gets a smaller but more powerful 2.9-liter twin-turbo V6 with a total output of 536 hp. We prefer Bentley use the latter, but there's a slight chance it could pair the PHEV system with the 4.0-liter twin-turbo V8 like the Porsche Panamera Turbo S E-Hybrid.

In the Panamera, this setup produces a whopping 690 hp.

Bentley has been testing this drivetrain for nearly half a decade, so it's unclear when a production model will arrive.

The PHEV Continental will likely arrive shortly after Rolls-Royce delivers its first all-electric model, the Spectre.

Even though Rolls-Royce now officially has an EV in its range, Bentley is still arguably ahead in terms of electrification. Following the recent introduction of two new Bentayga models, Bentley's range is now officially 50% electrified. Once the GTC PHEV is introduced, the British brand will lead the green charge in the ultra-luxury segment.

The company's delayed EV could be worth the long wait based on the teased performance specifications, which include a sub-two-second 0-60 mph time.
